defining biodiversity essay

ENCYCLOPEDIC ENTRY

Biodiversity.

Biodiversity refers to the variety of living species on Earth, including plants, animals, bacteria, and fungi. While Earth’s biodiversity is so rich that many species have yet to be discovered, many species are being threatened with extinction due to human activities, putting the Earth’s magnificent biodiversity at risk.

Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species  in one region or ecosystem . Bio diversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence. However, only around 1.2 million species have been identified and described so far, most of which are insects. This means that millions of other organisms remain a complete mystery.

Over generations , all of the species that are currently alive today have evolved unique traits that make them distinct from other species . These differences are what scientists use to tell one species from another. Organisms that have evolved to be so different from one another that they can no longer reproduce with each other are considered different species . All organisms that can reproduce with each other fall into one species .

Scientists are interested in how much biodiversity there is on a global scale, given that there is still so much biodiversity to discover. They also study how many species exist in single ecosystems, such as a forest, grassland, tundra, or lake. A single grassland can contain a wide range of species, from beetles to snakes to antelopes. Ecosystems that host the most biodiversity tend to have ideal environmental conditions for plant growth, like the warm and wet climate of tropical regions. Ecosystems can also contain species too small to see with the naked eye. Looking at samples of soil or water through a microscope reveals a whole world of bacteria and other tiny organisms.

Some areas in the world, such as areas of Mexico, South Africa, Brazil, the southwestern United States, and Madagascar, have more bio diversity than others. Areas with extremely high levels of bio diversity are called hotspots . Endemic species — species that are only found in one particular location—are also found in hotspots .

All of the Earth’s species work together to survive and maintain their ecosystems . For example, the grass in pastures feeds cattle. Cattle then produce manure that returns nutrients to the soil, which helps to grow more grass. This manure can also be used to fertilize cropland. Many species provide important benefits to humans, including food, clothing, and medicine.

Much of the Earth’s bio diversity , however, is in jeopardy due to human consumption and other activities that disturb and even destroy ecosystems . Pollution , climate change, and population growth are all threats to bio diversity . These threats have caused an unprecedented rise in the rate of species extinction . Some scientists estimate that half of all species on Earth will be wiped out within the next century. Conservation efforts are necessary to preserve bio diversity and protect endangered species and their habitats.

Biodiversity, also called biological diversity, is the variety of life found in a place on Earth or, often, the total variety of life on Earth. A common measure of this variety, called species richness, is the count of species in an area. Biodiversity also encompasses the genetic variety within each species and the variety of ecosystems that species create.

Examining counts of species is the most common method used to compare the biodiversity of various places. A second way to weigh species biodiversity is to recognize the unique biodiversity of those habitats that contain few but unusual species, such as volcanoes, thermal vents, and hot springs. In practice, biodiversity is weighted differently for different species.

What has led to the decline in biodiversity in recent times?

The pace of decline and extinctions in biodiversity has risen dramatically over the last century, as the effects of climate change increased and human activities such as agriculture, fishing, and hunting continued to encroach into more remote natural areas all over the world.

Which year was named the International Year of Biodiversity?

The United Nations named 2010 as the International Year of Biodiversity. It was a yearlong celebration intended to raise public awareness about the importance of biodiversity and the need to reinforce conservation efforts.

How many species are on the extinction list in the biodiversity report for 2019?

A 2019 report by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services noted that up to one million plant and animal species are facing extinction because of human activity.

biodiversity , the variety of life found in a place on Earth or, often, the total variety of life on Earth. A common measure of this variety, called species richness , is the count of species in an area. Colombia and Kenya , for example, each have more than 1,000 breeding species of birds , whereas the forests of Great Britain and of eastern North America are home to fewer than 200. A coral reef off northern Australia may have 500 species of fish, while the rocky shoreline of Japan may be home to only 100 species. Such numbers capture some of the differences between places—the tropics, for example, have more biodiversity than temperate regions—but raw species count is not the only measure of diversity . Furthermore, biodiversity encompasses the genetic variety within each species and the variety of ecosystems that species create.

(Read E.O. Wilson’s Britannica essay on mass extinction.)

Although examining counts of species is perhaps the most common method used to compare the biodiversity of various places, in practice biodiversity is weighted differently for different species, the reason being that some species are deemed more valuable or more interesting than others. One way this “value” or “interest” is assessed is by examining the diversity that exists above the species level, in the genera, families, orders, classes, and phyla to which species belong ( see taxonomy ). For example, the count of animal species that live on land is much higher than the count of those that live in the oceans because there are huge numbers of terrestrial insect species; insects comprise many orders and families, and they constitute the largest class of arthropods , which themselves constitute the largest animal phylum. In contrast, there are fewer animal phyla in terrestrial environments than in the oceans . No animal phylum is restricted to the land, but brachiopods ( see lamp shell ), pogonophorans ( see beardworm ), and other animal phyla occur exclusively or predominantly in marine habitats.

Some species have no close relatives and exist alone in their genus, whereas others occur in genera made up of hundreds of species. Given this, one can ask whether it is a species belonging to the former or latter category that is more important. On one hand, a taxonomically distinct species—the only one in its genus or family, for example—may be more likely to be distinct biochemically and so be a valuable source for medicines simply because there is nothing else quite like it. On the other hand, although the only species in a genus carries more genetic novelty, a species belonging to a large genus might possess something of the evolutionary vitality that has led its genus to be so diverse .

A second way to weight species biodiversity is to recognize the unique biodiversity of those environments that contain few species but unusual ones. Dramatic examples come from extreme environments such as the summits of active Antarctic volcanoes (e.g., Mt. Erebus [ see Ross Island ] and Mt. Melbourne in the Ross Sea region), hot springs (e.g., Yellowstone National Park in the western United States), or deep-sea hydrothermal vents ( see marine ecosystem: Organisms of the deep-sea vents ). The numbers of species found in these places may be smaller than almost anywhere else, yet the species are quite distinctive. One such species is the bacterium Thermus aquaticus , found in the hot springs of Yellowstone. From this organism was isolated Taq polymerase, a heat -resistant enzyme crucial for a DNA -amplification technique widely used in research and medical diagnostics ( see polymerase chain reaction ).

More generally, areas differ in the biodiversity of species found only there. Species having relatively small ranges are called endemic species . On remote oceanic islands, almost all the native species are endemic . The Hawaiian Islands , for example, have about 1,000 plant species, a small number compared with those at the same latitude in continental Central America . Almost all the Hawaiian species, however, are found only there, whereas the species on continents may be much more widespread. Endemic species are much more vulnerable to human activity than are more widely distributed species, because it is easier to destroy all the habitat in a small geographic range than in a large one.

In addition to diversity among species, the concept of biodiversity includes the genetic diversity within species. One example is our own species, for we differ in a wide variety of characteristics that are partly or wholly genetically determined, including height, weight , skin and eye colour, behavioral traits, and resistance to various diseases . Likewise, genetic variety within a plant species may include the differences in individual plants that confer resistance to different diseases. For plants that are domesticated, such as rice, these differences may be of considerable economic importance, for they are the source of new disease-resistant domestic varieties.

The idea of biodiversity also encompasses the range of ecological communities that species form. A common approach to quantifying this type of diversity is to record the variety of ecological communities an area may contain. It is generally accepted that an area having, say, both forests and prairies is more diverse than one with forests alone, because each of these assemblages is expected to house different species. This conclusion, however, is indirect—i.e., it is likely based on differences in vegetation structure or appearance rather than directly on lists of species.

Forest and prairie are just two of a plethora of names applied to ecological assemblages defined in a variety of ways, methods, and terms, and many ideas exist regarding what constitutes an assemblage. Technical terms that imply different degrees to which assemblages can be divided spatially include association , habitat , ecosystem , biome , life zone , ecoregion , landscape , or biotype . There is also no agreement on the boundaries of assemblages—say, where the forest biome ends and the prairie biome begins. Nonetheless, especially when these approaches are applied globally, as with the ecoregions used by the World Wide Fund for Nature (World Wildlife Fund, WWF), they provide a useful guide to biodiversity patterns.

The catalog of Earth’s biodiversity is very incomplete. About 1.9 million species have scientific names. Estimates of the total number of living species cluster around 10 million, which means that most species have not been discovered and described. (These estimates omit bacteria because of the practical problems in defining bacterial species.) Simply counting species must be, at best, an incomplete measure of biodiversity, for most species cannot be counted within a reasonable time. At the present rate of describing new species, it will take about 1,000 years to complete the catalog of scientific names. Of the approximately 1.9 million species now described, perhaps two-thirds are known from only one location and many from examining only one individual or a limited number of individuals, so knowledge of the genetic variation within species is even more constrained. From just a few well-studied species, it is clear that genetic variability can be substantial and that it differs in extent between species.

It should be noted that the pace of species population declines and extinctions has risen dramatically over the last century, as the effects of climate change increased and human activities such as agriculture, fishing , and hunting continued to encroach into more-remote natural areas. A 2019 report by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services noted that up to one million plant and animal species are facing extinction due to human activity. (The loss of biodiversity as a result of human activity and various methods aimed at preventing this loss are discussed in the articles conservation and biodiversity loss .)

To assist in the daunting challenge of protecting species, a number of biologically rich but threatened regions containing high numbers of endemic species have been identified and mapped. Such “ hot spots ” of biodiversity have been described to assist governments and nongovernmental organizations in the development of conservation priorities.

The United Nations named 2010 as the International Year of Biodiversity (IYB)—a yearlong celebration intended to raise public awareness about the importance of biodiversity and to reinforce conservation efforts. Many of the conservation goals promoted by the IYB have resurfaced periodically in later United Nations awareness campaigns—such as the International Year of Forests (2011), the International Year of Soil (2015), and the International Year of Sustainable Tourism for Development (2017).

Biodiversity includes not only species we consider rare, threatened, or endangered but also every living thing—from humans to organisms we know little about, such as microbes, fungi, and invertebrates.

At the Center for Biodiversity and Conservation, we include humans and human cultural diversity as a part of biodiversity. We use the term “ biocultural ” to describe the dynamic, continually evolving and interconnected nature of people and place, and the notion that social and biological dimensions are interrelated. This concept recognizes that human use, knowledge, and beliefs influence, and in turn are influenced, by the ecological systems of which human communities are a part. This relationship makes all of biodiversity, including the species, land and seascapes, and the cultural links to the places where we live—be right where we are or in distant lands—important to our wellbeing as they all play a role in maintaining a diverse and healthy planet.

How do we study biodiversity?

Exploration and monitoring.

To study biodiversity, scientists conduct expeditions to survey and monitor species, habitats, and their interactions. On these expeditions, scientists ask questions about, measure, and collect data on various dimensions, such as population sizes and trends, distribution and habitat use, and impacts of management or other human activities. From primates in Southeast Asia to flamingos in the Andes, the CBC is engaged in numerous monitoring projects across the globe.

Tools of the trade 

Biodiversity scientists use a variety of tools for collecting and analyzing data at various scales. Landscape monitoring techniques , for instance, use imaging systems such as remote sensing and drones to capture images across an area. Machine learning can be used to identify and count species or classify landscape types captured in these images or in video or audio clips. Mathematical modeling with software such as Maxent enables scientists to model species niches and distributions across these landscapes and predict how they will respond to climate change. New technological advances enhance our ability to monitor biodiversity and implement conservation and management activities.

Read more about the CBC’s Biodiversity Informatics Program to learn how information technology can be used to collect, organize, and analyze biodiversity data.

Synthesizing evidence

The vast knowledge collected through these various methods forms the evidence that decision-makers need to enact effective and sustainable conservation approaches.

Learn more about our evidence-informed practice by reading about the CBC’s Evidence Initiative .

Building capacity

By strengthening the ability of community leaders, educators, managers, and other professionals to study biodiversity, we improve our ability to effectively manage and conserve the variety of life.

The CBC’s program in Southeast Asia develops capacity for conservation science through multidisciplinary research training of Vietnames graduate and undergraduate students, direct training of protected area staff in survey techniques, and co-leading training workshops on improving wildlife trade management.

The CBC’s Network of Conservation Educators and Practitioners (NCEP) improves training, teaching, and learning in biodiversity conservation with up-to-date, open-access resources for teaching and learning on a range of conservation topics, and by leading training and research initiatives to advance the field of conservation education.

Why is biodiversity important?

Biodiversity is important to most aspects of our lives. We value biodiversity for many reasons, some utilitarian, some intrinsic. This means we value biodiversity both for what it provides to humans, and for the value it has in its own right. Utilitarian values include the many basic needs humans obtain from biodiversity such as food, fuel, shelter, and medicine. Further, ecosystems provide crucial services such as pollination, seed dispersal, climate regulation, water purification, nutrient cycling, and control of agricultural pests. Biodiversity also holds value for potential benefits not yet recognized, such as new medicines and other possible unknown services. Biodiversity has cultural value to humans as well, for spiritual or religious reasons for instance. The intrinsic value of biodiversity refers to its inherent worth, which is independent of its value to anyone or anything else. This is more of a philosophical concept, which can be thought of as the inalienable right to exist. Finally, the value of biodiversity can also be understood through the lens of the relationships we form and strive for with each other and the rest of nature. We may value biodiversity because of how it shapes who we are, our relationships to each other, and social norms. These relational values are part of peoples’ individual or collective sense of wellbeing, responsibility for, and connection with the environment. The different values placed on biodiversity are important because they can influence the conservation decisions people make every day.

Developing community-based partnerships are crucial for supporting communities in the management and conservation of biodiversity that are vital to their wellbeing.

Threats to Biodiversity

Over the last century, humans have come to dominate the planet, causing rapid ecosystem change and massive loss of biodiversity across the planet. This has led some people to refer to the time we now live in as the “anthropocene.” While the Earth has always experienced changes and extinctions, today they are occurring at an unprecedented rate. Major direct threats to biodiversity include habitat loss and fragmentation, unsustainable resource use, invasive species, pollution, and global climate change. The underlying causes of biodiversity loss, such as a growing human population and overconsumption are often complex and stem from many interrelated factors.

The good news is that it is within our power to change our actions to help ensure the survival of species and the health and integrity of ecological systems. By understanding threats to biodiversity, and how they play out in context, we can be best prepared to manage conservation challenges. The conservation efforts of the last decades have made a significant difference in the state of biodiversity today. Over 100,000 protected areas—including national parks, wildlife refuges, game reserves, and marine protected areas, managed both by governments and local communities—provide habitat for wildlife, and help keep deforestation in check. Other types of conservation actions such as restoration, reintroduction, and the control of invasive species, have also had positive impacts on conservation efforts And these efforts have been bolstered by continuous efforts to improve environmental policies at local, regional, and global scales. It is vitally important that these policies recognize and center local values, needs, and realities to sustainably manage resources for healthy ecological as well as human communities.  By acknowledging the interconnections and feedbacks between people and nature, assessing our existing knowledge, and applying evidence to our conservation decisions, we can develop effective approaches for conservation and sustainability for all life on Earth.

What Is Biodiversity?

Biodiversity.

Biodiversity is the extraordinary variety of life on Earth — from genes and species to ecosystems and the valuable functions they perform. E.O. Wilson, the noted biologist and author who coined the term “biodiversity,” explains it as “the very stuff of life.”

For at least 3.8 billion years, a complex web of life has been evolving on Earth. Millions of species inhabit land, freshwater, and ocean ecosystems. All species, including human beings, are intricately linked by their interactions with each other and the environments they live in.

Biodiversity — short for biological diversity — is the variety of all living things and their interactions. Biodiversity changes over time as extinction occurs and new species evolve.

Scientists often speak of three levels of diversity: species, genetic, and ecosystem diversity. In fact, these levels cannot be separated. Each is important, interacting with and influencing others. Changes at one level can cause changes at other levels.

What Is a Species?

Species come in all shapes and sizes, from organisms so small they can only be seen with powerful microscopes to huge redwood trees. They include bacteria, protozoa, fungi, flowering plants, ants, beetles, butterflies, birds, fishes, and large animals such as elephants, whales, and bears. Each species is a group of organisms with unique characteristics. An individual of a species can reproduce successfully, creating viable offspring, only with another member of that species.

We are still learning about how many species exist and how they relate to each other and their environment. Current estimates are of about 10 million species on Earth, of which only about 1.9 million have been named and catalogued. Scientists race to catalog species before they go extinct. An "endemic" species occurs in a particular area and nowhere else.

New species are still being discovered, for example by scientists from the Smithsonian National Museum of Natural History. Entomologist Dr. Jonathan Coddington and colleagues published the discovery of the largest web-spinning spider ( Nephila komaci ) in the world in 2009. In 2012, Dr. Terry Erwin and colleagues discovered 177 species of parasitic wasps . Using submersibles to study deep coral reefs, Icthyologist Dr. Carole Baldwin continues to encounter new species of fish . The study of fossils reveals new species from the past that are now extinct. For example, Paleobiologist Dr. Nick Pyenson and colleagues discovered that the diversity of sea cow species used to be higher on Earth.

When a new species is discovered, it is given a name. Scientific naming follows certain rules or conventions. A new species is assigned to a genus based on its relatedness to other organisms. Its unique species name may be related to one characteristic that makes the species different from others, the place it was found, or can have the name of a colleague.

In 2013, Smithsonian Mammalogist Dr. Kristofer Helgen and colleagues named the first new species of carnivorous mammal recorded from the Americas in 35 years. Its relatedness to "olingos" placed it in the genus Bassaricyon , while its species name, neblina , refers to the Andean cloud forests (neblina = "fog") in which it was found. A new species of jellyfish discovered by Dr. Allen Collins  was given the scientific name of Tamoya ohboya , thanks to a teacher's claim that people said "oh boy" when they saw it.

What Is Genetic Diversity?

Biodiversity includes the genes that every individual inherits from its parents and passes on to the next generation. Genetic diversity is found everywhere, from the variety of songs and feather colors of birds to the colors, tastes, and textures of apples and other foods. Genetic variation, which determines the extent to which individuals can adapt to their environments, is extremely important to their survival.

A genome is the complete set of genetic material (i.e., DNA) of an organism. To preserve Earth’s genomic diversity, scientists at the National Museum of Natural History are collecting and freezing hundreds of thousands of DNA samples. The collection will be used for the new field of genomics , a discipline that sequences, assembles, and analyzes the function and structure of genomes, providing information into the future about plants, animals, fungi, bacteria, and protists, even those that are extinct. The Smithsonian's repository of DNA is just one of many that together make up the Global Genome Project that seeks to preserve genetic samples from every species on Earth.

What Is Ecosystem Diversity?

Genes determine the traits of individuals that form populations of a species. Individuals from different species interact to form communities. These interact dynamically with non-living environmental components, such as water or minerals, to form an ecosystem. Some ecosystems such as tropical forests and coral reefs are especially complex and host a large number of species. Other ecosystems such as deserts and Arctic regions have less complexity and thus a lower number of species, but all those species are ecologically important and some are endemic to that ecosystem.

Monitoring Biodiversity

Many Smithsonian scientists are working on ways to monitor and measure biodiversity over time. Smithsonian Conservation Biology Institute scientists Dr. Francisco Dallmeier  and Dr. Alfonso Alonso  developed a Framework for the Assessment and Monitoring of Biodiversity. The framework provides guidance about how to go about designing and implementing assessments and monitoring programs, how to report the information gathered, and how to use the gathered scientific information to track the conditions of ecosystems and the species that inhabit them.

For more than three decades, Smithsonian scientists and institutional collaborators with the Forest Global Earth Observatory (ForestGEO) have been studying forest biodiversity and function at more than 60 sites around the world. A newer initiative, the Marine Global Earth Observatory (Marine GEO), brings together Smithsonian marine scientists from the U.S., Belize, and Panama to collaborate with colleagues from around the world to monitor ocean ecosystems.

Botanist Dr. John Kress  took a leadership role in 2006 when the Smithsonian and five other international scientific organizations founded what is now Consortium of Scientific Partners on Biodiversity and has grown to include 24 major scientific organizations as partners. The Consortium looks for innovative ways to investigate biodiversity and explore solutions to loss of biodiversity as humans continue to interact with the biosphere.

Essay on Biodiversity in 500 Words for Students

• Updated on  
• Dec 7, 2023

Essay on Biodiversity: Biodiversity refers to the variety of animals and plants in the world or a specific area. Even in today’s modern world where so many technological advances have taken place, we still rely on our natural environment and resources to survive, A healthy and vibrant ecosystem is not disturbed by human activities. We humans are the largest consumers of natural resources, and you know what? We are also a real threat to the natural environment? Biodiversity is not just about a variety of animal and plant species, but, also offers us water, climate, disease control, nutrition cycle, oxygen release, etc. According to one report released by the United Nations, around 10 lakh plant and animal species are on the verge of extinction. The worst thing is that this number is almost at a doubling rate.

Why is Biodiversity Important?

Biodiversity supports all life forms on earth. To understand the importance of biodiversity, we don’t need to think or act like a biologist. All we need is a holistic understanding. 

• Biodiversity promotes resilience and stability in our ecosystem. If there is any natural disturbance in the environment, a diverse ecosystem will be able to survive and recover better.
• Fields like agriculture, forestry, and medicine completely rely on biodiversity. We get genetic resources from biodiversity, which is essential for agriculture and medicine fields.
• A healthy biodiversity environment means healthy humans. The medicinal drugs we use are derived from plants, animals, and microorganisms.
• In many parts of the world, biodiversity is an integral part of cultural identity. Indigenous tribes are connected with their natural environment and species. 
• Forest areas and oceans play an important role in regulating global temperature and storing carbon dioxide.
• Our environment is constantly changing and the species around it also need to adapt to for to survive. Therefore, genetic diversity within species is also important.
• Natural activities like soil formation, nutrient cycling, water purification, etc, are all dependent on biodiversity.

What is Biodiversity Loss?

Biodiversity loss means the global extinction of various species, resulting in the loss of biological diversity. One of the main factors responsible for biodiversity loss is the conversion of natural habitats into agricultural and urban areas.

Biodiversity Essay

Broadly speaking, biodiversity, also known as biological diversity, refers to various types of plants and animals on Earth. The process of continuous biodiversity conservation is essential right now. A greater level of biodiversity is necessary to maintain the harmony of the natural environment. Here are a few sample essays on biodiversity.

100 Words Essay On Biodiversity

200 words essay on biodiversity, 500 words essay on biodiversity.

The term "biodiversity" is used to describe the variety of plants, animals, and other species found in an environment. All of them have a significant impact on preserving the planet's healthy ecosystem. In order to sustain the health of the ecosystem and human life, it is critical to maintain a high degree of biodiversity.

However, maintaining biodiversity is getting more challenging due to the increasing air, water, and land pollution on our planet. A number of plant and animal species have gone extinct as a result of the quick environmental changes brought on by the aforementioned causes of biodiversity loss.

By encouraging individuals to adopt more environmentally friendly behaviours and practises and to build a more peaceful and sympathetic relationship with the environment, it is possible to preserve biodiversity.

‘Bio’, which stands for life, and ‘diversity’, which means variety, make up the phrase "biodiversity." The diversity of life on Earth is referred to as biodiversity. Living species include all types of plants, animals, microorganisms, and fungus.

Benefits Of Biodiversity

Community engagement to protect biodiversity is crucial. Biodiversity has several economic advantages.

Many parts of the world benefit economically from biodiversity. The tourism and recreation industries are facilitated by biodiversity. National Parks and Natural Reserves gain a lot from it.

The best locations for ecotourism, photography, art, cinematography, and literary works are in forests, animal reserves, and sanctuaries.

Biodiversity is essential for maintaining the gaseous composition of the atmosphere, breaking down waste, and removing contaminants.

Biodiversity helps in improving soil quality.

Types Of Biodiversity

Genetic Biodiversity | Genetic diversity refers to the variance in genes and genotypes within a species, such as how each individual human differs from the others in appearance.

Species Biodiversity | The variety of species found in a habitat or an area is known as species diversity. It is the diversity of life that is seen in a community. Ecosystem Biodiversity | The diversity of plant and animal species that coexist and are linked by food webs and food chains is referred to as ecological biodiversity.

The biological diversity of many plants and animals is essential to everything. However, biodiversity is declining daily for a number of causes. Our planet could no longer be a place to live if it doesn't stop. Thus, several strategies help in boosting the earth's biodiversity. The three main threats to biodiversity today are habitat loss, hunting, and poaching. At an alarming rate, humans are destroying forests, grasslands, reefs and other natural areas.

Hundreds of species that live in these habitats are therefore vanishing every year. Due to population decline caused by illegal hunting and poaching, several species are put under even more stress.

Importance Of Biodiversity

Maintaining biodiversity is crucial for the health of the ecological system. Many species of plants and animals are dependent on each other. As a result, if one becomes extinct, the others will begin to become vulnerable. Additionally, as both plants and animals are necessary for human existence, it is crucial for us as well. For instance, in order to exist, humans require food, which we obtain from plants. We cannot produce any crops if the soil does not provide a conducive climate. As a result, we won't be able to live sustainably on this planet.

Biodiversity in both flora and fauna is essential today. Therefore, to prevent the decrease in species in danger, we need to implement a number of interventions. Furthermore, vehicle pollution should decrease. So that both humans and animals can get fresh air to breathe. Moreover, it will also decrease global warming which is the major cause of the extinction of the species.

How To Preserve Biodiversity

The basic goal of biodiversity conservation is to protect life on earth, all species, the ecosystem, and a healthy environment for all time so that it will continue to be healthy for future generations. The maintenance of the food chain, the provision of a healthy habitat for many animals, including people, and the promotion of our sustainable development all depend heavily on biodiversity conservation.

Here are some ways you can preserve biodiversity:

Set Up Gardens | The simplest approach to increase biodiversity is to build gardens inside of homes. In the yard or even on the balcony, you may grow a variety of plants. Additionally, this would contribute to bringing in more fresh air within the house.

Plant Local Flowers, Fruits And Vegetables | Plant a variety in your backyard or a hanging garden using the native plants, fruits, and vegetables of your region. Nurseries are excellent places to learn about caring for and preserving plants.

3 R’s | Reduce your consumption, reuse what you can, recycle before throwing away.

Since humans consume the majority of biodiversity resources, it is primarily their duty to maintain and safeguard biodiversity in order to save the environment. The diversity of species, the health of the ecosystem, the state of the environment, and the continued viability of life on earth are crucial. By maintaining and safeguarding species, ecosystems, and natural resources, biodiversity conservation can be achieved for the sustainability of a healthy planet. Some rare species can be saved with the help of law enforcement.

All living species are interconnected and can be negatively impacted by one disturbance and therefore maintaining biodiversity is crucial for human survival. Inadequate biodiversity protection puts human life, as well as the lives of plants, animals, and the environment, at danger. As a result, we must make every effort to preserve our biodiversity.

Biodiversity Explained: Facts, Myths, and the Race to Protect It

By MJ Altman on January 4, 2023

As ecosystems and habitats degrade and disappear worldwide, biodiversity — the interconnectedness of all forms of life on our planet — is in jeopardy. In light of a new global agreement to protect our lands, ocean, and waters, explore what biodiversity really means and what it will take to preserve life on Earth.

From microscopic fungi to mega forests, “biodiversity” is the collective term for the variety of life on Earth in all its forms. It is 4.5 billion years of evolution, embodied.

Biodiversity is responsible for our food, our soil, our water, our weather, even the air we breathe. Yet despite being a crucial foundation for our collective future, biodiversity is often lost amid conversations on climate change — until recently.

In December 2022, leaders from nearly 200 nations adopted a landmark UN agreement to reverse nature’s rapid decline before it’s too late. Known as the Kunming-Montreal Global Biodiversity Framework , it calls for protecting 30% of the planet’s land, ocean, and inland waters and includes 23 other targets to help restore and protect ecosystems and endangered species worldwide.

Here are 12 things you should know:

1. Biodiversity is more than just the total number of species on Earth.

“It is actually more complex than that,” Dr. Thomas Lovejoy, the late ecologist, told the United Nations Foundation in 2018. “It’s about the genetic diversity within species, the diversity of habitats, and the large biological units known as biomes.”

This includes the interactions that occur between species within ecosystems – primordial relationships that shape our environment in countless, often unseen ways.

“Without biological diversity, there is no other life on Earth — including our own,” he explained. “Even though we are often oblivious to it, this diversity of life is what provides clean water, oxygen, and all other things that end up being part of our diet, as well as clothing and shelter. It provides a lot of psychological benefits too, which are not much appreciated.”

2. We’re only just beginning to understand biodiversity’s influence and importance in our lives.

Earth’s many ecosystems rely on a delicate, complicated, and fascinating tangle of life that, in many ways, remains a mystery. In fact, the term “biological diversity” wasn’t introduced to the scientific community until 1980 in a research paper on species loss by Dr. Lovejoy. Scientists still haven’t identified all forms of life on the planet. New species are discovered every year.

Take kelp, for example. These undersea forests provide sustenance and shelter for marine species like chinook salmon, which, in turn, serve as a staple food for orcas. And kelp also absorb excess carbon dioxide, which can help mitigate climate change.

3. The planet’s biodiversity holds enormous, untapped potential for medical and scientific breakthroughs.

Lovejoy described each species on the planet as a unique set of solutions for a particular set of biological problems. “Whoever would have thought a bacterium from a Yellowstone hot spring would revolutionize forensic and diagnostic medicine, make the human genome project possible, and confer benefits in the trillion-dollar range?” he wrote as a Senior Fellow at the United Nations Foundation, citing a previously unknown and seemingly inconsequential microbe discovered in 1966 that revolutionized genetic testing and immunization development, including the COVID-19 vaccine.

Today, one-fourth of all modern medicines are derived from tropical plants, and 70% of all cancer drugs are natural or bio-inspired products. In the past decade, researchers in Nova Scotia found a soil fungus that can disarm antibiotic-resistant bacteria — a discovery that could transform the fields of medicine and agriculture. The possibilities for discovery and innovation are monumental.

4. Climate change and biodiversity are interconnected.

Climate change is causing biodiversity loss, and biodiversity loss is causing climate change. Here’s how: Destroying and degrading ecosystems releases more carbon dioxide into the atmosphere than burning fossil fuels.

Meanwhile, the consequences of burning fossil fuels — rising global temperatures, an increase in wildfires, and ocean acidification, to name a few — are threatening habitats and wildlife alike. In late 2019 and early 2020, for example, more than 60,000 koalas were killed by wildfires in Australia so massive that nearly 3 billion animals died or were displaced as a result. Earlier this year, the Australian government officially listed koalas as an endangered species.

At COP 27 last year, world leaders reached a historic agreement to create a “loss and damage” fund to support communities that are already feeling climate change’s disastrous impact, including biodiversity loss and its impact on livelihoods.

5. Biodiversity can help us adapt to climate change.

The UN considers biodiversity our strongest natural defense against climate change. Land and ocean ecosystems currently absorb 60% of human-caused emissions , and they are the planet’s only way of storing massive amounts of carbon dioxide. Coastal wetlands, for example, protect against storm surges and flooding during extreme weather while also storing carbon dioxide and creating oxygen.

According to a joint estimate by the UN Development Programme and the Government of Papua New Guinea, every dollar invested in environmental protection generates more than $2,500 in so-called ecosystem services — water regulation, coastal protection, carbon storage, and other invisible functions that nature provides. It’s one of the reasons that Papua New Guinea launched the first-ever national, independent Biodiversity and Climate Fund to protect its status as one of just 17 “megadiverse” countries.

6. Less biodiversity means a higher risk of disease.

For decades, the scientific community has warned that biodiversity loss increases the spread of infectious disease . Why? Because extinction upsets the ecosystem in unpredictable ways, and the destruction of natural habitats increases interaction between humans and wildlife. Biodiversity essentially acts as a barrier between humans and animal-borne disease.

Species that tend to survive logging, farming, mining, wildlife trade and consumption, and other human activities behind widespread biodiversity loss are often “vectors of disease” like mice and mosquitoes, which host pathogens that are able to make the jump to humans. It’s one of the reasons why cases of Lyme disease in the northeast United States have spiked in recent decades: With fewer mammals to prey on, ticks are increasingly seeking out people. In fact, roughly 75% of emerging infectious diseases are zoonotic .

It’s also why researchers like Dr. Alessandra Nava and her team of virus hunters at Brazil’s Fiocruz Amazônia are tracking the spread of disease in bats, monkeys, and rodents in the world’s largest rainforest. Their goal is to stay a step ahead of future pandemics by better understanding the pathogens contained within the jungle’s creatures before they come in contact with humans — encounters that become more likely as the human footprint expands.

7. Biodiversity on land depends on biodiversity in water.

Maintaining the ocean’s ecological balance is crucial for protecting biodiversity on land, as well as maintaining our ability to feed future generations. The ocean plays a vital role in regulating the planet’s weather and water and the air we breathe. It is also the planet’s largest source of protein , feeding more than 3 billion people every day who rely on fish as a staple food.

Yet the ocean remains a vastly unexplored ecological frontier. While scientists have identified 200,000 marine species , the actual number is estimated to be in the millions. Unsustainable fishing practices, pollution, climate change, and habitat destruction are threatening creatures that may vanish before we even knew they existed.

8. Our planet’s biodiversity is on the brink.

Some 1 million species are threatened with extinction right now. That’s more than any other time in history, and they’re disappearing at a rate that is 1,000 times the norm. The culprit is the way most humans consume, produce, travel, and live.

A 2019 UN report found that we have altered 75% of the planet’s terrestrial environment, 40% of its marine environment, and 50% of streams and rivers. Nearly three-fourths of our freshwater resources are devoted to crop or livestock production, which often means using pesticides, fertilizers, fuels, and antibiotics that pollute our rivers, streams, seas, and soil. Every day we are destroying habitats and degrading massive amounts of soil and water through industrial manufacturing and agriculture while jeopardizing precious natural resources that could be lost forever in our lifetime; in the past two decades, we’ve lost half of the planet’s coral reefs . Deforestation in the Amazon rainforest hit a record high last year; some 18% is gone already, with scientists warning that we’re approaching a tipping point toward potential collapse .

9. Sustainability is the only way forward.

Such irresponsible production and consumption of our natural resources come at a catastrophic cost. We are destroying our planet at an unprecedented rate and losing a vast number of plants, animals, insects, and marine life in the process — to the detriment of our own future. Humanity’s health and well-being are dependent on a biodiverse planet.

Fortunately, examples are emerging of a greener, more sustainable way of doing business. Circular economic models are becoming more common as companies realize the economic and environmental value of reducing, reusing, and recycling their supply chain. At the same time, more citizens are demanding sustainable sourcing and socially just labor practices from their consumer goods. In 2022, the founder of the outdoor retailer Patagonia announced plans to invest all of the company’s profits toward combating climate change . “If we have any hope of a thriving planet — much less a business — 50 years from now, it is going to take all of us doing what we can with the resources we have,” Yvon Chouinard wrote .

10. Indigenous communities are crucial.

For thousands of years, Indigenous communities have served as the planet’s most effective environmental stewards. Today, according to the UN, Indigenous people manage more than 20% of the planet’s land and 80% of its biodiversity. “For us, it is not a passion, or a job,” Hindou Ibrahim of the Mbororo tribe in Chad, an SDG (Sustainable Development Goal) Advocate and Indigenous rights activist, told the UN last year. “It is our way of living. And that’s what we have done for all generations.”

In 2015, the UN created the Local Communities and Indigenous Peoples Platform to ensure their formal participation in global negotiations on climate change.

11. Conservation is critical.

One of our most promising solutions is preservation. Restoring degraded ecosystems alone could provide up to one-third of the climate mitigation needed to keep the Earth from warming too far above pre-industrial levels. This means creating protected areas, curbing extractive capitalism, and restoring the planet’s enormous amount of degraded land.

People across the globe are leading efforts to do just that. One inspiring example is Rita Mesquita, who expanded the amount of protected rainforest in Brazil by 76% during her time in the country’s Ministry of the Environment. Today, she oversees programs that encourage residents and visitors alike in Manaus to interact with the surrounding Amazon rainforest.

12. We need cooperation — and revolution — at all levels.

We need partnerships among countries, communities, consumers, and corporations. And we’re seeing signs of progress every day. In fact, at COP 27, the Governments of Brazil, Democratic Republic of Congo, and Indonesia announced an alliance to protect their respective rainforests. Their historic agreement could pave the way for more multilateral action and impact. Coming just a month later, the Kunming-Montreal Global Biodiversity Framework represents an enormous and long-awaited step toward halting extinction rates that some scientists are calling an existential crisis akin to climate change.

A huge part of the solution to the biodiversity challenge will be transforming how we approach the natural world and our place within it. As Dr. Lovejoy told the UN Foundation in 2018 , “There needs to be a major shift in perception from thinking of nature as something with a fence around it in the middle of an expansive, human-dominated landscape … to thinking about embedding our aspirations in nature.”

Essay on Biodiversity

Biodiversity is a term made up of two words - Bio meaning Life, and Diversity meaning Variety. The term biodiversity refers to the variety of life on Earth. Plants, animals, microbes, and fungi are all examples of living species on the planet.

Types of Biodiversity  

Genetic Biodiversity- Genetic diversity is the variation in genes and genotypes within a species, e.g., every human looks different from the other. 

Species Biodiversity- Species Diversity is the variety of species within a habitat or a region. It is the biodiversity observed within a community.

Ecosystem Biodiversity- Ecological biodiversity refers to the variations in the plant and animal species living together and connected by food chains and food webs.

Importance of Biodiversity 

Biodiversity is an integral part of cultural identity. Human cultures co-evolve with their environment and conservation is a priority for cultural identity. Biodiversity is used for Medicinal purposes.

Many plants and animals are used for medicinal purposes, like vitamins and painkillers. It contributes to climate stability. It helps in controlling the effects of climate change and managing greenhouse gases. 

Biodiversity provides more food resources. It supplies many vital ecosystems, such as creating and maintaining soil quality, controlling pests, and providing habitat for wildlife. Biodiversity has a relationship with Industry. Biological sources provide many Industrial materials including rubber, cotton, leather, food, paper, etc.

There are many economic benefits of Biodiversity. Biodiversity also helps in controlling pollution. Biodiversity helps in forming a healthy ecosystem. Biodiversity also acts as a source of recreation. Along with other factors, biodiversity helps in improving soil quality.

Long Essay on Biodiversity 

There are many economic benefits of Biodiversity. Biodiversity is a source of economic wealth for many regions of the world. Biodiversity facilitates Tourism and the Recreational industry. Natural Reserves and National Parks benefit a lot from it. Forest, wildlife, biosphere reserve, sanctuaries are prime spots for ecotourism, photography, painting, filmmaking, and literary works.

Biodiversity plays a vital role in the maintenance of the gaseous composition of the atmosphere, breakdown of waste material, and removal of pollutants.

Conservation of Biodiversity  

Biodiversity is very important for human existence as all life forms are interlinked with each other and one single disturbance can have multiple effects on another. If we fail to protect our biodiversity, we can endanger our plants, animals, and environment, as well as human life. Therefore, it is necessary to protect our biodiversity at all costs. Conservation of Biodiversity can be done by educating the people to adopt more environment-friendly methods and activities and develop a more harmonious and empathetic nature towards the environment. The involvement and cooperation of communities are very important. The process of continuous protection of Biodiversity is the need of the hour.

The Government of India, along with 155 other nations, has signed the convention of Biodiversity at the Earth Summit to protect it. According to the summit, efforts should be made in preserving endangered species. 

The preservation and proper management methods for wildlife should be made. Food crops, animals, and plants should be preserved. Usage of various food crops should be kept at a minimum. Every country must realize the importance of protecting the ecosystem and safeguarding the habitat. 

The Government of India has launched the Wild Life Protection Act 1972 to protect, preserve, and propagate a variety of species. The Government has also launched a scheme to protect national parks and sanctuaries. There are 12 countries - Mexico, Columbia, Peru, Brasil, Ecuador, Democratic Republic of Congo, Madagascar, India, China, Malaysia, Indonesia, and Australia, in which Mega Diversity Centres are located. These countries are tropical and they possess a large number of the world’s species.

Various hotspots have been made to protect the vegetation. There are various methods for conserving biodiversity. 

If biodiversity conservation is not done efficiently, each species would eventually become extinct due to a lack of appetite and hunger. This scenario has been a big issue for the last few decades, and many unique species have already become extinct. As a result of a lack of biodiversity protection, several species are still on the verge of extinction.

FAQs on Biodiversity Essay

1. What are the three types of Biodiversity?

Biodiversity is referred to as the variability that exists between the living organisms from different sources of nature, such as terrestrial, marine, and other aquatic ecosystems. Biodiversity has three levels, which are genetic, species, and ecosystem diversity. This is also considered as the type of ecosystem.

2. What is Biodiversity and why is it important?

Biodiversity is responsible for boosting the productivity of the ecosystems in which every species, no matter how small, has an important role to play. For example, a greater variety of crops can be obtained from a plant species which is in large numbers. If species diversity is in a greater amount, then it ensures natural sustainability for all life forms.

3. What is the connection between Biodiversity and the Food Chain?

If a single species goes extinct from the food chain, it will have an impact on the species that survive on it, putting them on the verge of extinction.

4. How are human beings affecting biodiversity?

Pollution- Pollution not only affects human beings, but also affects our flora and fauna, and we should control the pollution to conserve our biodiversity.

Population- Population control is a must to maintain a balance in our ecological system. Humans contribute to pollution by bursting crackers and by not following all the traffic rules.

5. How does Deforestation affect biodiversity?

Deforestation- Trees are very important for survival. They help in balancing out the ecosystem. Deforestation leads to the destruction of habitat. Deforestation should be stopped to protect our animals and plants. Deforestation not only removes vegetation that is important for removing carbon dioxide from the atmosphere, but it also emits greenhouse gases.

Biodiversity and Ecosystem Stability

Introduction: Biodiversity, Stability, and Ecosystem Functioning

Climate change and other human-driven (anthropogenic) environmental changes will continue to cause biodiversity loss in the coming decades (Sala et al . 2000), in addition to the high rates of species extinctions already occurring worldwide (Stork 2010). Biodiversity is a term that can be used to describe biological diversity at a variety of different scales, but in this context we will focus on the description of species diversity. Species play essential roles in ecosystems, so local and global species losses could threaten the stability of the ecosystem services on which humans depend (McCann 2000). For example, plant species harness the energy of the sun to fix carbon through photosynthesis, and this essential biological process provides the base of the food chain for myriad animal consumers. At the ecosystem level, the total growth of all plant species is termed primary production, and — as we'll see in this article — communities composed of different numbers and combinations of plant species can have very different rates of primary production. This fundamental metric of ecosystem function has relevance for global food supply and for rates of climate change because primary production reflects the rate at which carbon dioxide (a greenhouse gas) is removed from the atmosphere. There is currently great concern about the stability of both natural and human-managed ecosystems, particularly given the myriad global changes already occurring. Stability can be defined in several ways, but the most intuitive definition of a stable system is one having low variability (i.e., little deviation from its average state) despite shifting environmental conditions. This is often termed the resistance of a system. Resilience is a somewhat different aspect of stability indicating the ability of an ecosystem to return to its original state following a disturbance or other perturbation.

Species Identity, Functional traits, and Resource-Use

Species diversity has two primary components: species richness (the number of species in a local community) and species composition (the identity of the species present in a community). While most research on the relationship between ecosystem diversity and stability has focused on species richness, it is variation in species composition that provides the mechanistic basis to explain the relationship between species richness and ecosystem functioning. Species differ from one another in their resource use, environmental tolerances, and interactions with other species, such that species composition has a major influence on ecosystem functioning and stability.

The traits that characterize the ecological function of a species are termed functional traits, and species that share similar suites of traits are often categorized together into functional groups. When species from different functional groups occur together, they can exhibit complementary resource-use, meaning that they use different resources or use the same resources at different times. For example, two animal predators may consume different prey items, so they are less likely to compete with one another, allowing higher total biomass of predators in the system. In the case of plants, all species may utilize the same suite of resources (space, light, water, soil nutrients, etc.) but at different times during the growing season — for example, early- and late-season grasses in prairies. Increasing species diversity can influence ecosystem functions — such as productivity — by increasing the likelihood that species will use complementary resources and can also increase the likelihood that a particularly productive or efficient species is present in the community. For example, high plant diversity can lead to increased ecosystem productivity by more completely, and/or efficiently, exploiting soil resources (e.g., nutrients, water). While primary production is the ecosystem function most referred to in this article, other ecosystem functions, such as decomposition and nutrient turnover, are also influenced by species diversity and particular species traits.

Diversity-Stability Theory

Theoretical models suggest that there could be multiple relationships between diversity and stability, depending on how we define stability (reviewed by Ives & Carpenter 2007). Stability can be defined at the ecosystem level — for example, a rancher might be interested in the ability of a grassland ecosystem to maintain primary production for cattle forage across several years that may vary in their average temperature and precipitation. Figure 1 shows how having multiple species present in a plant community can stabilize ecosystem processes if species vary in their responses to environmental fluctuations such that an increased abundance of one species can compensate for the decreased abundance of another. Biologically diverse communities are also more likely to contain species that confer resilience to that ecosystem because as a community accumulates species, there is a higher chance of any one of them having traits that enable them to adapt to a changing environment. Such species could buffer the system against the loss of other species. Scientists have proposed the insurance hypothesis to explain this phenomenon (Yachi & Loreau 1999). In this situation, species identity — and particular species traits — are the driving force stabilizing the system rather than species richness per se (see Figure 2).

In contrast, if stability is defined at the species level, then more diverse assemblages can actually have lower species-level stability. This is because there is a limit to the number of individuals that can be packed into a particular community, such that as the number of species in the community goes up, the average population sizes of the species in the community goes down. For example, in Figure 2, each of the simple communities can only contain three individuals, so as the number of species in the community goes up, the probability of having a large number of individuals of any given species goes down. The smaller the population size of a particular species, the more likely it is to go extinct locally, due to random — stochastic — fluctuations, so at higher species richness levels there should be a greater risk of local extinctions. Thus, if stability is defined in terms of maintaining specific populations or species in a community, then increasing diversity in randomly assembled communities should confer a greater chance of destabilizing the system.

Experiments and Observations Can Evaluate the Diversity-Stability Relationship

A wealth of research into the relationships among diversity, stability, and ecosystem functioning has been conducted in recent years (reviewed by Balvanera et al . 2006, Hooper et al . 2005). The first experiments to measure the relationship between diversity and stability manipulated diversity in aquatic microcosms — miniature experimental ecosystems — containing four or more trophic levels, including primary producers, primary and secondary consumers, and decomposers (McGrady-Steed et al . 1997, Naeem & Li 1997). These experiments found that species diversity conferred spatial and temporal stability on several ecosystem functions. Stability was conferred by species richness, both within and among functional groups (Wardle et al . 2000). When there is more than one species with a similar ecological role in a system, they are sometimes considered "functionally redundant." But these experiments show that having functionally redundant species may play an important role in ensuring ecosystem stability when individual species are lost due to environmental changes, such as climate change.

More recently, scientists have examined the importance of plant diversity for ecosystem stability in terrestrial ecosystems, especially grasslands where the dominant vegetation lies low to the ground and is easy to manipulate experimentally. In 1995, David Tilman and colleagues established 168 experimental plots in the Cedar Creek Ecosystem Science Reserve, each 9 x 9 m in size (Figure 3A), and seeded them with 1, 2, 4, 8 or 16 species drawn randomly from a pool of 18 possible perennial plant species (Tilman et al . 2006). Plots were weeded to prevent new species invasion and ecosystem stability was measured as the stability of primary production over time. Over the ten years that data were collected, there was significant interannual variation in climate, and the researchers found that more diverse plots had more stable production over time (Figure 3B). In contrast, population stability declined in more diverse plots (Figure 3C). These experimental findings are consistent with the theory described in the prior section, predicting that increasing species diversity would be positively correlated with increasing stability at the ecosystem-level and negatively correlated with species-level stability due to declining population sizes of individual species.

Experiments manipulating diversity have been criticized because of their small spatial and short time scales, so what happens in naturally assembled communities at larger spatial scales over longer time scales? In a 24-year study of naturally assembled Inner Mongolia grassland vegetation, Bai et al . (2004) observed variation in the biomass of species, functional groups, and the whole community in response to strong interannual variation in growing-season precipitation. They found that while the abundance of individual species fluctuated, species within particular functional groups tended to respond differently such that a decrease in the abundance of one species was compensated for by an increase in the abundance of another. This compensation stabilized the biomass productivity of the whole community in a fluctuating environment (see Figure 1). These findings demonstrate that local species richness — both within and among functional groups — confers stability on ecosystem processes in naturally assembled communities.

Experiments in aquatic ecosystems have also shown that large-scale processes play a significant role in stabilizing ecosystems. A whole-lake acidification experiment in Canada found that although species diversity declined as a result of acidification, species composition changed significantly and ecosystem function was maintained (Schindler 1990). This suggests that given sufficient time and appropriate dispersal mechanisms, new species can colonize communities from the regional species pool and compensate for those species that are locally lost (Fischer et al . 2001). This observation emphasizes the importance of maintaining connectivity among natural habitats as they experience environmental changes.

Evidence from multiple ecosystems at a variety of temporal and spatial scales, suggests that biological diversity acts to stabilize ecosystem functioning in the face of environmental fluctuation. Variation among species in their response to such fluctuation is an essential requirement for ecosystem stability, as is the presence of species that can compensate for the function of species that are lost. While much of the evidence presented here has focused on the consequences of changes in species diversity on primary production in natural ecosystems, recent research has found similar relationships between species diversity and ecosystem productivity in human-managed ecosystems (e.g., Jactel et al . 2005).

Essay on Biodiversity 1000+ Words

Biodiversity, short for biological diversity, is a remarkable tapestry of life that blankets our planet. It encompasses the variety of living organisms, ecosystems, and habitats that make Earth a vibrant and thriving place. In this essay, we will delve into the importance of biodiversity, the threats it faces, and why we should protect it.

The Marvelous World of Biodiversity

Imagine a world without colorful flowers, buzzing bees, towering trees, or majestic tigers. Biodiversity is what makes our world so diverse and beautiful. It includes everything from tiny microbes in the soil to the largest whales in the ocean. Earth’s rich biodiversity provides us with essential resources, from food to medicine, and enriches our lives in countless ways.

The Benefits of Biodiversity

Biodiversity is not just about pretty landscapes and exotic animals; it plays a crucial role in sustaining life on Earth. It helps maintain a stable and healthy environment. For instance, forests with diverse tree species are better at absorbing carbon dioxide, a greenhouse gas that contributes to climate change. Biodiversity also supports pollinators like bees and butterflies, which are essential for our food supply. The more diverse our ecosystems, the more resilient they are to threats like diseases and extreme weather.

Food and Medicine

Biodiversity is the foundation of our food system. Different plant and animal species provide us with a wide range of foods, from fruits and vegetables to grains and meats. Moreover, many of the medicines we rely on come from plants and animals. For example, the bark of the willow tree gave us aspirin, and the Madagascar periwinkle plant provides a lifesaving medicine for cancer patients. Protecting biodiversity ensures that we have a diverse and healthy diet and access to essential medicines.

Cultural and Recreational Value

Biodiversity isn’t just about science and survival; it also enriches our cultures and leisure activities. Many indigenous communities around the world have deep cultural connections to the land and its diverse species. Biodiversity inspires art, literature, and music. Imagine a world without the fascinating stories of animals like the African elephant or the enchanting songs of birds like the nightingale. Biodiversity enhances our quality of life in ways we might not even realize.

Threats to Biodiversity

Despite its immense value, biodiversity is under threat. Human activities, such as deforestation, pollution, overfishing, and habitat destruction, are driving many species to the brink of extinction. Climate change, fueled by the burning of fossil fuels, poses another significant threat. Rising temperatures can disrupt ecosystems and push species out of their habitats. These threats not only endanger the creatures themselves but also disrupt the delicate balance of our planet.

Conservation Efforts

The good news is that people around the world are working hard to protect biodiversity. Conservation organizations, scientists, and governments are implementing measures to safeguard endangered species and preserve critical habitats. National parks and wildlife reserves provide safe havens for countless plants and animals. Additionally, there are international agreements like the Convention on Biological Diversity aimed at preserving biodiversity on a global scale.

What You Can Do

You, as a young environmental advocate, can also play a crucial role in protecting biodiversity. You can start by learning more about the species and ecosystems in your area. Participate in local conservation efforts, like planting trees or cleaning up parks. Reduce your environmental footprint by conserving water, reducing waste, and using energy-efficient appliances. Spread the word about the importance of biodiversity to inspire others to take action.

Conclusion of Essay on Biodiversity

In conclusion, biodiversity is a precious gift that we must cherish and protect. It sustains life on Earth, provides us with essential resources, and enriches our cultures and enjoyment of the natural world. However, it faces serious threats from human activities and climate change. By understanding the importance of biodiversity and taking action to conserve it, we can ensure a healthier and more vibrant planet for future generations. Let us celebrate the wonders of biodiversity and work together to safeguard the incredible diversity of life on Earth.

Introduction:

Biodiversity also known as biological diversity is the variables that exist among several species living in the ecosystem. These living organisms include marine, terrestrial and aquatic life. Biodiversity aims to understand the positions these organisms occupy in the broader ecosystem.

Importance of Biodiversity:

When there is biodiversity in our ecosystem it translates to a greener environment. This is because plant life thrives in a balanced ecosystem. This invariably affects humans as we consume plants for our survival. Also, a healthy ecosystem can help to reduce the risk of diseases and the way we respond to them.

Increasing Biodiversity:

Some changes could be encouraged to improve biodiversity in our environment.

Some of them are:

1. Stopping penetration of invasive alien species.

2. Using sustainable agricultural methods.

3. Having protected areas for spices to thrive.

4. Having an organic maintenance culture for fertilizers.

Conclusion:

To make the world a safe place for all organisms, we must maintain good health in all the ecosystems. This is the benefit of paying attention to biodiversity.

Diversity is the hallmark of nature. Things exist in different forms which creates diversity. Biodiversity is a significant and desirable variation in plant and animal existence on the surface of the earth. The variation exists due to genetics, species and the ecosystem or the habitat. Biodiversity is an important aspect in the world because it enables the survival and sustainability of living things on earth.

Types of Biodiversity:

The variation in living things has resulted in different types of biodiversity depending on the certain variables. Genetic diversity is due to the genetic components shared by living organisms. The species that have similar genes diverge and they develop differently thus creating biodiversity. Species diversity occurs when a habitat comprises different kinds of living things. Ecological diversity is through the interaction of living things that share common sources of energy in an ecosystem which contributes to biodiversity.

The existence of living things in an ecosystem and the functioning of the ecosystem contribute to the relevance of biodiversity in nature. Through biodiversity, living organisms are able to acquire food and other important resources to sustain their lives. The climate and environmental changes are regulated because of biodiversity. The culture is enriched through biodiversity as it involves existence of several groups of species and people in one environment.

All the three types of biodiversity are important to the existence of living organisms. The ecosystem is the hallmark of diversity because it helps to sustain the lives of diverse living things.

Biodiversity is the variability or the diversity of the different species of life forms. The planet earth is habitat for a wide variety of flora and fauna like plants, animals and other life forms.

What is Biodiversity?

Biodiversity or Biological diversity refers to the variety and variability of living beings on planet earth and it is the degree of variation of life. It represents the wealth of biological assets available on earth and encompasses microorganism, plants, animals and ecosystems such as coral reefs, forests, rainforests, deserts etc.

Threats to Biodiversity:

The growing population, industrialization, technology, etc., all are impacting biodiversity. The increased human activities have been reducing the natural area for plants, animals and other living things. A number of plants and animals have gone extinct because of increased deforestation and other factors. Growing pollution, causing global warming and climate change, is a big threat to biodiversity. The decline in biodiversity would in turn lead to imbalance in the ecosystem and would become a threat to the human race as well as other living organisms.

Different plants and animals are dependent on others to live and keep the natural surroundings in a balanced state. For example, human beings are dependent on various plants and animals for their food, shelter, safety, clothes etc. Similarly, every living species is dependent on some other species. It is, therefore, important to preserve biodiversity in our planet in order to maintain the ecological balance.

Protecting Biodiversity:

As we know, the biodiversity loss is a serious threat for human race, we all should work for maintaining biodiversity, and find out solutions to reduce the biodiversity decline. Since, air pollution and deforestation are major threats to biodiversity, these are the first things that need to be controlled. Government should frame stricter laws and organizations should sensitize people to be concerned about it and contribute their bit.

Biodiversity, also referred to as the biological diversity refers to the diversified form of plants and animals that exists in our planet . It also denotes each and every aspect of the ecosystem such as micro-organisms, coral reefs, rainforests, deserts, forests etc.,

A good balance in biodiversity supports human race and humans on the other hand must ensure to save biodiversity. This essay is going to talk about the importance of biodiversity and the role of human beings in safeguarding the ecosystem.

There are more than 300,000 species of flora that has been identified and there should be many more unidentified varieties. Similarly there must be infinite variety of other species in our Earth and these together form a perfect natural protection for the human race. Biodiversity supports human race in different ways.

Few of them are listed below:

1. Some of the species capture and stores energy and releases it back in the atmosphere for human consumption.

2. Some biological species help in decomposing organic materials and thus acts as a natural recycling agent.

3. Plants and trees help in reducing pollution and maintain the purity of atmospheric air.

4. It is from the biological resources that humans receive food and shelter.

5. The astonishing beauty of biodiversity is the base for tourism industry to flourish.

Decline in Biodiversity:

The Earth’s biodiversity is undergoing a severe decline and this is a great threat to the human race. There are several factors that lead to the decline in biological species, the most significant one being the behavior of human beings.

1. Human beings destroy forests to build houses and offices. Through deforestation humans are actually destroying the natural habitat of many plants and animals.

2. All new scientific inventions are causing harm to the environment. We cannot even find some species of birds today because of the increase in noise pollution.

3. Global warming is another reason for the decline in biodiversity. Some species require specific climate to survive and when the climatic conditions change continuously these species either migrate or become extinct. Decline in the number of coral reefs are a perfect example.

Steps to Be Taken:

The Government and different voluntary organizations must act upon immediately to create awareness among people on environmental issues and its consequences. It is also the responsibility of every common man to save mother Earth by maintaining a rich biodiversity .

If proper care is not taken, the biodiversity of Earth may become extinct one day and if it happens then, humans have to find another planet to live. It’s better to act now before it gets too late.

Biodiversity can be said to mean the extreme importance of a very wide variety of animals and plants that are resident on the planet earth or in a particular habitat. It is very necessary to maintain the level of biodiversity on the earth so that the environmental harmony can be balanced. Biological diversity is another name for biodiversity and is widely the variability or diversity of all the different species of animals and plants on this planet. Having a very high biodiversity is extremely essential to help maintain the surroundings in a state of harmony. Biodiversity can be loosely defined as a variety of fauna and flora that are available in a specific habitat or the planet earth. Biodiversity is largely originated from the terms – species diversity and species richness.

Biodiversity is mainly a united view of the biological varieties. A lot of other words and terms have been at one time or another used to explain diversity. Some of these terms include taxonomic diversity (this comes from a species diversity point of view), ecological diversity (this comes from an ecosystem diversity point of view), morphological diversity (this comes from a genetic diversity point of view) and functional diversity (this comes from the point of view of the functions of the species). Biodiversity gives quite a uniform view of the above discussed biological varieties.

Biological diversity is quite important because its helps maintain the ecological balance in a system. Different animals and plants depend on one another to fulfill all of their needs. For example, we human beings depend on various animals and plants for our clothes, shelter and food. Other species also do the same and depend on a variety of other species to sustain them and provide them with the basics. Biodiversity and its beautiful richness ensure that the earth is fit enough for the survival of each and every one of the organism living on the earth. However, the ever increasing pollution is negatively affecting biodiversity. Quite a lot of animals and plants have gone into extinction as a result of this pollution and a lot more are going to become extinct if proper care is not taken and the pollution of the environment continues to exponentially and this would cause a sharp decline in the biodiversity.

We human beings have to understand how important the maintenance of the immensely rich biodiversity is. Smokes from vehicles causes a high rate of air pollution and this causes harm to a lot of species. The level of pollution in the atmosphere has to be put under control. Water bodies like seas, oceans and rivers are polluted by the release of industrial wastes into the. These wastes are very harmful to the marine organism and life in the water bodies. There is therefore a need to try as much as possible to dispose industrial wastes through other means and methods that do not harm the environment. The industrial wastes can be primarily treated before being disposed into the water properly and safely.

When you are a biology student biodiversity is one of the most important words you can learn. Not only that but it also becomes your lives calling to maintain it. But let’s not get ahead of ourselves before we can understand why it is important, we need to understand what it is.

This term refers to the many different life forms that inhabit the earth at this moment, this includes bacteria, plants, animals and humans and it also refers to their shared environment. Life has manifested itself in many different forms we do not know why exactly but we are certain that they all exist and depend on each other for survival.

Why is biodiversity important?

The answer to this question is more important than just simply stating what biodiversity is. My personal experience as a student has thought me that I learn best when I have an example so I will give you an example of the importance of biodiversity.

The famous Yellowstone Park is a natural reserve and national park but before it was declared as such it was just another forest that man wanted to hunt in. The geographical region had many wolfs inhabiting its plains, for generations they were hunted until they became extinct in the region. After a while, the coyotes began to reproduce as they hade more space and they started hunting the small mammals, which lead to a decrease in the population of eagles in the area but the most significant change came because of the deer. After fifty years of no wolfs in the park the number of roe deer rose and since they had no natural predators, they no longer feared open grasslands. That’s when they started grazing extensively which depleted the grass on the shore of the Yellow stone river and this, in turn, made the soil loos. The river began to take away a lot of soil and to deposit it in other places flooding certain areas while at the same time causing droughts to happen in other places.

Biologists came to the park with a wish to restore its wolf population and after a decade of planning and working they restored one pack to the park. The pack soon made the deer go back to the forest so they could be harder to hunt, the coyote’s population dropped because they couldn’t compete with the wolf, that led to the increase of small rodents which let to the return of carnivores’ grate birds. But above all the grazing on the river edge stopped and after a few years, the Yellowstone river returned to its natural flow.

This story is completely true and I love to use it as an example of the importance of maintaining biodiversity. There are many regions in the world that have similar problems and if we do not do our best to conserve biodiversity, we could be looking at similar or even worst natural catastrophes.

People tend to mass produce and they do this with most things. They will destroy a forest of many thousands of life forms to make a plantation with one single plant, the same is true of animal farming. With our need to be productive all the time we lose sight of the small things that make the system function as whole. Even though an insignificant thing as a bug or a wolf pack might seem the least important for our daily lives once we take them out of the picture, we see that the balance and wealth biodiversity gives to the planet is not something that can be easily compensated.

The genetic, species and ecosystem variability of flora and fauna on earth are known as Biodiversity. For painting what exactly is Biodiversity, we need a large canvas beyond imagination. Such is the volume of the subject. But, the actual meaning and terms are still not clear.

Keeping it very simple and to the point, the term ‘Biodiversity’ comprises of two words. The first word is Bio, and the other one is Diversity. Bio means the forms of life and Diversity means mixture or variety. So, when both the words combine they form a definition like this ‘Biodiversity means various and mixed forms of life on earth.’ The variety of life forms on earth includes plants and animals and their natural habitat.

Facts about Biodiversity:

Digging into the term ‘Biodiversity’ more generously makes us realize that we have over 10,000 species of birds on earth. The amazing number blows everyone’s mind. Insects have a different counting, and their species are in millions. Plants are also a part of this biological system, and hence there are more than 20,000 species of plants.

Even after so many species of plants, animals and insects have specified there are still over millions of species which are not known by anyone. These species cannot be counted under any head as they don’t pursue an identity. The actual picture says that earth is home to almost 50 million species or even more than that. These facts do not conclude the point because one or the other day there may be many new species evolving.

Biodiversity is essential for survival. The importance of Biodiversity not only related to plants, animals and natural habitat. But it also provides us so many natural products such as fibre and timber and the fresh water to carry out our daily lives. Therefore we need to understand the importance of Biodiversity.

1.   The natural and organic resources:

In the happiness of living our lives, we often forget that Biodiversity is a part of nature. We should protect it no matter whatever be the limitations. Mother Nature has provided us with enough resources which are the Biological Resources. These include wood, medicines, food, etc., which are direct blessings of Biological System or by-product of the Biological Systems. Herbs and plants play a vital role in producing medicines. They may get their final touch from the pharmaceutical companies, but the original source is plants which are again a part of Biodiversity.

2. Biodiversity provides fibres:

It is important to know that wool, jute, palms, etc., use to produce various types of fibres after processing which are again part of the Biological Systems. So, if biodiversity does not persist how people will have access to these fibres? Flax plants use for the production of linen, which is extensively using for making clothes. Similarly, Corchorus plants and Agave plants are using for the production of Jute and sisal respectively. These fibres are no doubt essential for the cloth industry. Therefore it becomes our duty to maintain the Biodiversity.

3. Powerful benefits of Biodiversity:

People may not be aware of the importance, but there are many spiritual benefits of biodiversity. Our folk dances, mythology, and history have a deep link with the Biodiversity in one or the other way. Everyone enjoys or experience the Biodiversity in a different format. Biological diversity also contributes to attracting tourists, especially flora and fauna, which is a rare phenomenon in cities. Therefore it is our ethical duty to preserve Biodiversity.

Preserve Biodiversity:

There are different ways in which we can preserve our Biological environment. Biodiversity should be protected by following these ways.

i. People should stop the process of hunting and poaching the animals. They are a part of Biodiversity.

ii. Protection of endangered species and their surroundings.

iii. We need to curb pollution for protecting Biodiversity.

iv. The explosive growth of population is a threat to Biodiversity. So, to maintain the biological balance, we need to have the population growth under control. Otherwise, people will be exploiting natural resources unethically for survival.

All steps must be taken to protect biodiversity. Things may seem difficult in the initial stages but practicing them will lead to genuine results. Creating awareness on environmental issues and the negative impact of the loss of biodiversity will let people understand the inevitable need for biodiversity conservation.

It is our responsibility to protect the endangered species of plant and animals. If one wants to reach their destination, then it is imperative to take the first step. Without taking a step forward, things will never change on their own. To make a better tomorrow, we need to take steps for preserving our very own Biodiversity.

Biodiversity is a term used to refer the different forms of life on the Earth. It also includes the variety of species in the ecosystem. There is an uneven distribution of the biodiversity on the Earth due to the extreme variation of temperatures in different regions. For instance, it is more in regions near the equator due to warm climatic conditions. However, near the pole, the extreme cold and unfavourable weather conditions do not support a majority of life forms. Additionally, changes in climatic conditions on the Earth over a period of time have also led to the extinction of a number of species.

Biodiversity is often defined at different levels depending upon the category of species. For example, taxonomic diversity is used to measure the species diversity level of different forms of life on the Earth. Ecological diversity is a broader term used for the ecosystem diversity. Similarly, functional diversity is a type used to measure diversity based on their feeding mechanisms along with other functions of species within a population.

Distribution:

There is an uneven distribution of biodiversity on the Earth. In fact, it increases from pole to equator. The climatic conditions of a region decide the presence of different species in an area. Not all species can survive in all weather conditions. Moreover, lower altitudes have a high concentration of species as compared to higher altitudes.

The importance of biodiversity does not only lie in the survival of various species of the earth. There is social, cultural as well as the economic importance of it as well. Biodiversity is of extreme importance to maintain the balance of nature. It is vital to maintaining the food chain as well. One species may be the food for another species and various species are linked to each other through this food chain. Apart from this, there is scientific importance of the biodiversity as well. The research and breeding programmes involve the variety of species. If these species cease to exist then such programmes shall not be possible.

Also, most of the drugs and medicine which are vital for the cure of many diseases are also made from many plants and animals. For instance, penicillin is a fungus through which the penicillin antibiotic is extracted.

Another important importance of biodiversity is that it provides food to all including human beings. All the food we consume is either derived from plants or animals such as fishes and other marine animals. They are also the source of new crops, pesticides and source material for agricultural practices.

Biodiversity is also important for industrial use. We get many products such as fur, honey, leather and pearls from animals. Moreover, we get timber for plants which are the basis of the paper we use in our everyday life. Tea, coffee and other drinks along with dry fruits and our regular fruits and vegetables, all are obtained from the various plants.

There is cultural and religious importance of many species as well. Many plants and animals are worshipped in different cultures and religions such as Ocitnum sanctum (Tulsi) which is a plant worshipped by Hindus.

Biodiversity in India:

India ranks among the top 12 nations which have a rich heritage of biodiversity. There are about 350 different species of mammals along with 12000 different species of birds which are found in India. Additionally, there are around 50000 species of insects which have their habitat in our country. There are a wide variety of domestic animals such as cows and buffaloes along with marine life which is found in India. Moreover, India is a land of 10 different biographical regions which include islands, Trans Himalayas, Desert, Western Ghats, Gangetic Plain, Semi-arid zone, Northeastern zone, Deccan Plateau, Coastal islands and the Western Ghats.

The Gradual Decrease:

Not all species which existed in the ancient times exist today as well. For example, dinosaurs used to exist on our planet in older times. But they were not able to adapt to the changing environmental conditions which led to their extinction from the Earth. Similarly, there are many other species which are on the verge of extinction due to the urbanisation and modernisation of the world. With the increase in population, there has been a constant need to reduce the forest areas and make way for new cities. This has led to the reduction in forests which are the natural habitat for many wild animals and plants. Due to this many wild plants have become extinct and there has been an increase in the man-animal conflict as well. Hence there has been a need to conserve the biodiversity so as to maintain the balance of nature.

Initiatives for the Conservation of Biodiversity:

There have been initiatives by the governments all over the world to conserve the existing biodiversity on the earth. For example, there are dedicated national parks which earmark the area for wild animals and plants and reduce human intervention in their lives. There are various wildlife conservation programmes in place to protect the vulnerable and endangered species. For example, Project Tiger is one such measure in place to increase the population of tigers in our country.

There are also many laws in place which make the hunting of endangered and vulnerable animals a punishable offence. At the international level, UNESCO (United Nations Educational, Scientific and Cultural Organization) and IUCN (International Union for Conservation of Nature and Natural Resources) have also initiated many programmes in order to preserve various species.

It is not possible for the human to live all alone on the Earth. Various other life forms are equally important and play their roles in the mutual survival of the various species on the Earth. Each one of species has its own set of contribution for the environment. Already many species have become extinct as they were not able to survive in the changing weather conditions. Hence it is our duty to ensure that our activities do not affect the other flora and fauna on the planet. Although there are a number of steps taken by the government so as to preserve the various life forms, we should also contribute individually towards this cause. If we do not act today, we may yet again witness the extinction of the vulnerable biodiversity which may further disturb the balance of nature.

Types of Biodiversity

Importance of Biodiversity

Biodiversity in india, biodiversity definition.

“Biodiversity is the variation among living organisms from different sources including terrestrial, marine and desert ecosystems, and the ecological complexes of which they are a part.”

What is Biodiversity?

Biodiversity describes the richness and variety of life on earth. It is the most complex and important feature of our planet. Without biodiversity, life would not sustain.

The term biodiversity was coined in 1985. It is important in natural as well as artificial ecosystems. It deals with nature’s variety, the biosphere. It refers to variabilities among plants, animals and microorganism species.

Biodiversity includes the number of different organisms and their relative frequencies in an ecosystem. It also reflects the organization of organisms at different levels.

Biodiversity holds ecological and economic significance. It provides us with nourishment, housing, fuel, clothing and several other resources. It also extracts monetary benefits through tourism. Therefore, it is very important to have a good knowledge of biodiversity for a sustainable livelihood.

Also Read:  Flagship Species

There are the following three different types of biodiversity:

• Genetic Biodiversity
• Species Biodiversity
• Ecological Biodiversity

Species diversity  

Species diversity refers to the variety of different types of species found in a particular area. It is the biodiversity at the most basic level. It includes all the species ranging from plants to different microorganisms.

No two individuals of the same species are exactly similar. For example, humans show a lot of diversity among themselves. 

Genetic diversity

It refers to the variations among the genetic resources of the organisms. Every individual of a particular species differs from each other in their genetic constitution. That is why every human looks different from each other. Similarly, there are different varieties in the same species of rice, wheat, maize, barley, etc.

Ecological diversity  

An ecosystem is a collection of living and non-living organisms and their interaction with each other. Ecological biodiversity refers to the variations in the plant and animal species living together and connected by food chains and food webs.

It is the diversity observed among the different  ecosystems in a region. Diversity in different ecosystems like deserts, rainforests, mangroves, etc., include ecological diversity.

Biodiversity and its maintenance are very important for sustaining life on earth. A few of the reasons explaining the importance of biodiversity are:

Ecological Stability

Every species has a specific role in an ecosystem. They capture and store energy and also produce and decompose organic matter. The ecosystem supports the services without which humans cannot survive. A diverse ecosystem is more productive and can withstand environmental stress.

Economic Importance

Biodiversity is a reservoir of resources for the manufacture of food, cosmetic products and pharmaceuticals.

Crops livestock, fishery, and forests are a rich sources of food.

Wild plants such as Cinchona and Foxglove plant are used for medicinal purposes.

Wood, fibres, perfumes, lubricants, rubber, resins, poison and cork are all derived from different plant species.

The national parks and sanctuaries are a source of tourism. They are a source of beauty and joy for many people.

Ethical Importance

All species have a right to exist. Humans should not cause their voluntary extinction. Biodiversity preserves different cultures and spiritual heritage. Therefore, it is very important to conserve biodiversity.

India is one of the most diverse nations in the world. It ranks ninth in terms of plant species richness. Two of the world’s 25 biodiversity hotspots are found in India. It is the origin of important crop species such as pigeon pea, eggplant, cucumber, cotton and sesame. India is also a centre of various domesticated species such as millets, cereals, legumes, vegetables, medicinal and aromatic crops, etc.

India is equally diverse in its faunal wealth. There are about 91000 animal species found here.

However, diversity is depleting at a drastic rate and various programmes on biodiversity conservation are being launched to conserve nature.

Why is biodiversity important?

Biodiversity is essential for the processes that support all life on Earth, including humans. Without a wide range of animals, plants and microorganisms, we cannot have the healthy ecosystems that we rely on to provide us with the air we breathe and the food we eat. And people also value nature of itself.

Some aspects of biodiversity are instinctively widely valued by people but the more we study biodiversity the more we see that all of it is important – even bugs and bacteria that we can’t see or may not like the look of. There are lots of ways that humans depend upon biodiversity and it is vital for us to conserve it. Pollinators such as birds, bees and other insects are estimated to be responsible for a third of the world’s crop production. Without pollinators we would not have apples, cherries, blueberries, almonds and many other foods we eat. Agriculture is also reliant upon invertebrates – they help to maintain the health of the soil crops grow in.  Soil is teeming with microbes that are vital for liberating nutrients that plants need to grow, which are then also passed to us when we eat them. Life from the oceans provides the main source of animal protein for many people.

Trees, bushes and wetlands and wild grasslands naturally slow down water and help soil to absorb rainfall. When they are removed it can increase flooding. Trees and other plants clean the air we breathe and help us tackle the global challenge of climate change by absorbing carbon dioxide. Coral reefs and mangrove forests act as natural defences protecting coastlines from waves and storms. 

Many of our medicines, along with other complex chemicals that we use in our daily lives such as latex and rubber, also originate from plants. Spending time in nature is increasingly understood to lead to improvements in people’s physical and mental health. Simply having green spaces and trees in cities has been shown to decrease hospital admissions, reduce stress and lower blood pressure.

What is a diversity essay, identify how you will enrich the campus community, share stories about your lived experience, explain how your background or identity has affected your life, other interesting articles, frequently asked questions about college application essays.

Diversity essays ask students to highlight an important aspect of their identity, background, culture, experience, viewpoints, beliefs, skills, passions, goals, etc.

Diversity essays can come in many forms. Some scholarships are offered specifically for students who come from an underrepresented background or identity in higher education. At highly competitive schools, supplemental diversity essays require students to address how they will enhance the student body with a unique perspective, identity, or background.

In the Common Application and applications for several other colleges, some main essay prompts ask about how your background, identity, or experience has affected you.

Why schools want a diversity essay

Many universities believe a student body representing different perspectives, beliefs, identities, and backgrounds will enhance the campus learning and community experience.

Admissions officers are interested in hearing about how your unique background, identity, beliefs, culture, or characteristics will enrich the campus community.

Through the diversity essay, admissions officers want students to articulate the following:

• What makes them different from other applicants
• Stories related to their background, identity, or experience
• How their unique lived experience has affected their outlook, activities, and goals

Prevent plagiarism. Run a free check.

Think about what aspects of your identity or background make you unique, and choose one that has significantly impacted your life.

For some students, it may be easy to identify what sets them apart from their peers. But if you’re having trouble identifying what makes you different from other applicants, consider your life from an outsider’s perspective. Don’t presume your lived experiences are normal or boring just because you’re used to them.

Some examples of identities or experiences that you might write about include the following:

• Race/ethnicity
• Gender identity
• Sexual orientation
• Nationality
• Socioeconomic status
• Immigration background
• Religion/belief system
• Place of residence
• Family circumstances
• Extracurricular activities related to diversity

Include vulnerable, authentic stories about your lived experiences. Maintain focus on your experience rather than going into too much detail comparing yourself to others or describing their experiences.

Keep the focus on you

Tell a story about how your background, identity, or experience has impacted you. While you can briefly mention another person’s experience to provide context, be sure to keep the essay focused on you. Admissions officers are mostly interested in learning about your lived experience, not anyone else’s.

When I was a baby, my grandmother took me in, even though that meant postponing her retirement and continuing to work full-time at the local hairdresser. Even working every shift she could, she never missed a single school play or soccer game.

She and I had a really special bond, even creating our own special language to leave each other secret notes and messages. She always pushed me to succeed in school, and celebrated every academic achievement like it was worthy of a Nobel Prize. Every month, any leftover tip money she received at work went to a special 509 savings plan for my college education.

When I was in the 10th grade, my grandmother was diagnosed with ALS. We didn’t have health insurance, and what began with quitting soccer eventually led to dropping out of school as her condition worsened. In between her doctor’s appointments, keeping the house tidy, and keeping her comfortable, I took advantage of those few free moments to study for the GED.

In school pictures at Raleigh Elementary School, you could immediately spot me as “that Asian girl.” At lunch, I used to bring leftover fun see noodles, but after my classmates remarked how they smelled disgusting, I begged my mom to make a “regular” lunch of sliced bread, mayonnaise, and deli meat.

Although born and raised in North Carolina, I felt a cultural obligation to learn my “mother tongue” and reconnect with my “homeland.” After two years of all-day Saturday Chinese school, I finally visited Beijing for the first time, expecting I would finally belong. While my face initially assured locals of my Chinese identity, the moment I spoke, my cover was blown. My Chinese was littered with tonal errors, and I was instantly labeled as an “ABC,” American-born Chinese.

I felt culturally homeless.

Speak from your own experience

Highlight your actions, difficulties, and feelings rather than comparing yourself to others. While it may be tempting to write about how you have been more or less fortunate than those around you, keep the focus on you and your unique experiences, as shown below.

I began to despair when the FAFSA website once again filled with red error messages.

I had been at the local library for hours and hadn’t even been able to finish the form, much less the other to-do items for my application.

I am the first person in my family to even consider going to college. My parents work two jobs each, but even then, it’s sometimes very hard to make ends meet. Rather than playing soccer or competing in speech and debate, I help my family by taking care of my younger siblings after school and on the weekends.

“We only speak one language here. Speak proper English!” roared a store owner when I had attempted to buy bread and accidentally used the wrong preposition.

In middle school, I had relentlessly studied English grammar textbooks and received the highest marks.

Leaving Seoul was hard, but living in West Orange, New Jersey was much harder一especially navigating everyday communication with Americans.

After sharing relevant personal stories, make sure to provide insight into how your lived experience has influenced your perspective, activities, and goals. You should also explain how your background led you to apply to this university and why you’re a good fit.

Include your outlook, actions, and goals

Conclude your essay with an insight about how your background or identity has affected your outlook, actions, and goals. You should include specific actions and activities that you have done as a result of your insight.

One night, before the midnight premiere of Avengers: Endgame , I stopped by my best friend Maria’s house. Her mother prepared tamales, churros, and Mexican hot chocolate, packing them all neatly in an Igloo lunch box. As we sat in the line snaking around the AMC theater, I thought back to when Maria and I took salsa classes together and when we belted out Selena’s “Bidi Bidi Bom Bom” at karaoke. In that moment, as I munched on a chicken tamale, I realized how much I admired the beauty, complexity, and joy in Maria’s culture but had suppressed and devalued my own.

The following semester, I joined Model UN. Since then, I have learned how to proudly represent other countries and have gained cultural perspectives other than my own. I now understand that all cultures, including my own, are equal. I still struggle with small triggers, like when I go through airport security and feel a suspicious glance toward me, or when I feel self-conscious for bringing kabsa to school lunch. But in the future, I hope to study and work in international relations to continue learning about other cultures and impart a positive impression of Saudi culture to the world.

The smell of the early morning dew and the welcoming whinnies of my family’s horses are some of my most treasured childhood memories. To this day, our farm remains so rural that we do not have broadband access, and we’re too far away from the closest town for the postal service to reach us.

Going to school regularly was always a struggle: between the unceasing demands of the farm and our lack of connectivity, it was hard to keep up with my studies. Despite being a voracious reader, avid amateur chemist, and active participant in the classroom, emergencies and unforeseen events at the farm meant that I had a lot of unexcused absences.

Although it had challenges, my upbringing taught me resilience, the value of hard work, and the importance of family. Staying up all night to watch a foal being born, successfully saving the animals from a minor fire, and finding ways to soothe a nervous mare afraid of thunder have led to an unbreakable family bond.

Our farm is my family’s birthright and our livelihood, and I am eager to learn how to ensure the farm’s financial and technological success for future generations. In college, I am looking forward to joining a chapter of Future Farmers of America and studying agricultural business to carry my family’s legacy forward.

Tailor your answer to the university

After explaining how your identity or background will enrich the university’s existing student body, you can mention the university organizations, groups, or courses in which you’re interested.

Maybe a larger public school setting will allow you to broaden your community, or a small liberal arts college has a specialized program that will give you space to discover your voice and identity. Perhaps this particular university has an active affinity group you’d like to join.

Demonstrating how a university’s specific programs or clubs are relevant to you can show that you’ve done your research and would be a great addition to the university.

At the University of Michigan Engineering, I want to study engineering not only to emulate my mother’s achievements and strength, but also to forge my own path as an engineer with disabilities. I appreciate the University of Michigan’s long-standing dedication to supporting students with disabilities in ways ranging from accessible housing to assistive technology. At the University of Michigan Engineering, I want to receive a top-notch education and use it to inspire others to strive for their best, regardless of their circumstances.

3 Biodiversity: Its Meanings, Roles, and Status

• Published: January 2014
• Cite Icon Cite
• Permissions Icon Permissions

This chapter reviews biodiversity science concepts that lead to both definitions and metrics for tracking change. Beyond its general meaning, the term “biodiversity” is now common in a wide range of situations, from ecology, through conservation biology, nature conservation, environmental sciences, and environmental policy. Common approaches to measuring biodiversity are outlined and its roles, state, and trends described in way that is relevant for economics. There are many perceptions of what biodiversity includes and how to measure changes over time and space. It is argued that the starting point for economic valuation must come from accounting properly for the benefits that flow from biodiversity. Included are the general categories of intrinsic and extrinsic values, ecosystem services, heritage, adaptability, and resilience, and relevant components and metrics of biodiversity for each of these are indicated, and areas where there are significant gaps in knowledge and information identified.

Essay on Conservation of Biodiversity for Students and Children

500+ words essay on conservation of biodiversity.

Conservation of biodiversity is vital for maintaining the Earth’s environment and sustaining life on the planet. There are a number of ways in which the richness of biodiversity helps in maintaining the ecological system. Conservation of biodiversity is important for the survival of living beings on Earth. Hence, a lot of emphases is being given on the conservation of biodiversity these days.

The Extinction in Biodiversity

Due to human activities, numerous varieties of animals go extinct each year. Western Black Rhinoceros, Dodo, Tasmanian tiger, Golden Toad, Woolly Mammoth, Caribbean Monk Seal, Ivory-billed Woodpecker, and Japanese Sea Lion are some of the species of animals that have gone extinct.

Lemur, Mountain Gorilla, Vaquita, Sea Turtles, Amur Leopard, and Tiger are some of the species that are on the verge of extinction. Apart from these many species of plants and trees including Lepidodendron, Araucaria Mirabilis, Wood Cycad and Kokia Cookie have gone extinct and many species are endangered.

Need to Conserve Biodiversity

Earth is a beautiful planet which has given us many things which occur naturally. Natural resources, rivers, valleys , oceans, different species of animals and beautiful varieties of plants and trees are among some of these.

In today’s world, we are busy developing our surroundings and spoiling our beautiful environment. Today, we have exploited most of the things that were available abundantly in nature. Thus, there arises a need to conserve these natural things. Among other things, there is a serious need for the conservation of biodiversity.

Importance of Conservation of Biodiversity

Conservation of biodiversity is important for many reasons. Here are some of the main reasons to conserve biodiversity:

• Process of Food Chain: Different species of animals and plants serve as the source of food for other animals and living organisms. Thus, conserving biodiversity help to keep the food chain among the living organisms.
• Nutritional Needs: The decline in the variety of plants and animals would mean the decline in the variety of food we eat. So, this is likely to result in nutritional deficiencies.
• Cleaner Air: Plants and trees have a greater ability to purify the air and keep the atmosphere clean. As there is a decrease in the number and types of trees and plants, it impacts the quality of air in a negative way.
• Better Cultivation of Crops:   Fertility of soil is maintained by many insects, organisms and microorganisms work on different levels. So we have to maintain the level of microorganism which is better for the cultivation of crops.
• For Medical Reason s: For making different medicines many species of trees and plants are used so as to cure various diseases.

Methods to Conserve Biodiversity

Methods that can help in the conservation of biodiversity are

• Control Population: The greater the population the higher the needs which would result in further exploitation of flora and fauna and decline in biodiversity. For the conservation of biodiversity, we have to control the human population and allow other species of plants and animals to replenish on our planet.
• Control Pollution: The changing climate, deteriorating air quality and the growing amount of pollution on land and water bodies are leading to different types of diseases in many. It is essential to reduce the activities leading to pollution so as to conserve biodiversity.
• Reduce Deforestation: Due to deforestation, there is the loss of habitat. Due to this reason, wild animals are unable to survive in the new environment and die.
• Avoid Wastage: We need to understand that natural resources are not only essential for us but are also vital for the survival of other species. We must thus utilize only as much as we require them so that these remain available in abundance in nature for future use.
• Spread Awareness: Apart from this, one of the best methods to conserve biodiversity is by spreading awareness. The government can do so at a bigger level. While we can spread awareness by word of mouth and through social media.

Conservation of biodiversity is of utmost importance. We must all make efforts to conserve biodiversity rather than contributing towards its declination. Thus, the richness of biodiversity is essential for the survival of living beings on Earth.

Biodiversity Benefits for Ecology Essay

Introduction

Benefits of biodiversity.

According to the most common definition, biodiversity simply refers to having a variety of species. It is a reflection of the population, variety and variability of organisms on earth. Biodiversity includes diversification within and between different species and among ecosystems.

This variation of species in the ecosystem is a very important concept and factor that indeed is the basis for sustaining life on our planet. Considering such a great role of this matter, it is regrettable that biodiversity has been threatened by a number of factors largely fueled by human activities in recent days. This essay discusses the benefits of biodiversity on both the human beings and other living things.

To start with, biodiversity provides most of the food that humans and other living beings use for their survival. Humans feed on a wide array of living organisms like animals, plants, fish and others, which provide holistic nutritional value to them. Likewise, predators depend on other animals for food while plants rely on microorganisms to keep soil suitable for growth. Clearly, with an alteration in biodiversity, not only humans but also many other species of living things stand to suffer.

Secondly, biodiversity is a primary and great source of medicines and herbs used all around the world to treat various illnesses and health conditions. In the developing world, herbs are harvested directly even where drugs are manufactured for the ingredients to be primarily sourced from living things, especially plants. To give a more specific example, penicillin and anesthetics, which are commonly used in human treatment, are got from animal species and microbes.

Biodiversity is important for fighting against different threats that can harm our health and life. With a rich genetic composition within a species, the capacity to counter different bacteria, virus and other health impairing factors is greatly improved. For example, human beings avoid inbreeding in order to expand their genetic diversity, thereby this factor gives them an advantage and better chances to survive genetic and health attacks.

In addition, biodiversity is important for global warming mitigation. There are several plant tissues and organic matters on land and in ocean ecosystems that process carbon, which is part of the combination of greenhouse gasses contributing to climate change. For instance, as a measure for controlling the rate of global warming and desertification, countries worldwide have launched campaigns to plant many trees so that they can act as carbon sinks.

Again, biodiversity is very important for sustaining the global economy. Many people derive direct and indirect incomes from exploiting biodiversity. Indeed, it provides an important contribution to the economic development of all the nations of the world. Natural pesticides, fibers, waxes, fuel, gums, dyes and many others are goods harvested from biodiversity. Also, nature related holidays and ecotourism that are the main sources of income of many countries rely on biodiversity.

Moreover, the most important supporter of life, which is soil and water in it, depends on biodiversity for its maintenance. If the soil were eroded, then life would cease to exist very quickly. Microorganisms in the soil are responsible for breaking down organic matter and serving plants with essential nutrients. Vegetation, on the other hand, keeps soil intact and protects it.

Clean air that is very essential for life is purified by plant species, which filter unwanted and harmful particles from industries, recycle oxygen and regulate atmospheric composition. Indeed, plants use carbon dioxide to manufacture food and give out oxygen in its place.

Humans depend a lot on planted crops to provide food which are, however, susceptible to many pests. Other organisms including insects, birds and fungi eliminate a great majority of the potential pests that attack crops. These natural and cheap ways of controlling pests are far superior to artificial ones as pests often develop resistance to the latter.

The intrinsic value of biodiversity must not be also overlooked. Human beings and a number of other animals enhance their emotional wellbeing by being close to natural beauty. For example, the mutually helpful relationships between humans and biodiversity are easily discernible in arts, traditions and religions of diverse cultures all over the world. For instance, a picture depicting a beautiful; nature where green and healthy trees are represented is considered by many to have a calming effect on the human’s mind.

Generally, biodiversity provides all the basic needs of men and other higher animals. The provision of food, shelter, clothing and all the other basic needs can be traced back to the issue under the consideration. In fact, almost all food comes from living things, fabric for clothes is made from plants and skin or fir of animals while many of the materials used by people to build houses also have an organic nature and are the results of biodiversity.

That is why it is necessary to state that biodiversity is not just an important and beneficial but crucial aspect of life. Nature has its own way of balancing life, and biodiversity is at the center of this grand plan. Every single organism that exists on our planet has a role to play in supporting other life forms in all the different ecosystems. Biodiversity must be, therefore, protected and preserved if humans want the life to be sustained.

Build a Corporate Culture That Works

There’s a widespread understanding that managing corporate culture is key to business success. Yet few companies articulate their culture in such a way that the words become an organizational reality that molds employee behavior as intended.

All too often a culture is described as a set of anodyne norms, principles, or values, which do not offer decision-makers guidance on how to make difficult choices when faced with conflicting but equally defensible courses of action.

The trick to making a desired culture come alive is to debate and articulate it using dilemmas. If you identify the tough dilemmas your employees routinely face and clearly state how they should be resolved—“In this company, when we come across this dilemma, we turn left”—then your desired culture will take root and influence the behavior of the team.

To develop a culture that works, follow six rules: Ground your culture in the dilemmas you are likely to confront, dilemma-test your values, communicate your values in colorful terms, hire people who fit, let culture drive strategy, and know when to pull back from a value statement.

Start by thinking about the dilemmas your people will face.

Idea in Brief

The problem.

There’s a widespread understanding that managing corporate culture is key to business success. Yet few companies articulate their corporate culture in such a way that the words become an organizational reality that molds employee behavior as intended.

What Usually Happens

How to fix it.

Follow six rules: Ground your culture in the dilemmas you are likely to confront, dilemma-test your values, communicate your values in colorful terms, hire people who fit, let culture drive strategy, and know when to pull back from a value.

At the beginning of my career, I worked for the health-care-software specialist HBOC. One day, a woman from human resources came into the cafeteria with a roll of tape and began sticking posters on the walls. They proclaimed in royal blue the company’s values: “Transparency, Respect, Integrity, Honesty.” The next day we received wallet-sized plastic cards with the same words and were asked to memorize them so that we could incorporate them into our actions.

Deciphering the Significance of the Estates General: an In-depth Exploration of its Definition and Impact

This essay about the Estates General examines its role and significance in medieval France. It explores how this tripartite assembly, representing the clergy, nobility, and commoners, served as a governance forum and a reflection of societal dynamics. The text discusses the historical origins, the debates surrounding its impact, and its legacy in promoting political expression, dissent, and the early seeds of democratic ideals. The essay concludes by highlighting the Estates General’s lasting influence on the evolution of governance and representation.

How it works

In the vast expanse of historical chronicles, few elements are as richly layered or as hotly contested as the Estates General. Arising from the complexities of medieval France, this institution not only functioned as a governance nexus but also reflected the intricate societal dynamics of its time. Its importance transcends mere politics, embodying the power struggles, the pursuit of representation, and the evolution of governance systems.

At its core, the Estates General was a tripartite assembly, with each segment representing a different estate: the clergy, the nobility, and the commoners.

Each estate possessed a single vote, thereby mirroring the hierarchical structure of society where privilege and status determined influence. Summoned occasionally by the monarch, it served as a forum for discussions on various issues, including taxation and legislation. Yet, its convocation was more than just an administrative formality; it represented the monarch’s duty to engage with subjects and seek their collective wisdom, a principle deeply rooted in medieval political philosophy.

The origins of the Estates General can be traced back to the early Middle Ages, with foundations in the assemblies convened by Charlemagne and his successors. However, it was not until the 14th century that the institution took on its recognizable form. The convocation by Philip IV in 1302 marked a significant turning point, establishing a precedent for future monarchs to seek the counsel and consent of their subjects.

Debate persists regarding the significance and impact of the Estates General. Critics often view it as a mere façade—a theatrical display designed to appease the nobility and clergy. Indeed, its proceedings frequently devolved into stalemates and discord, reflecting the divergent interests of its constituent estates. Moreover, its authority was limited, with real power remaining firmly in the hands of the monarch.

However, such criticisms fail to acknowledge the Estates General’s potential as a venue for political expression and dissent. Despite its limitations, it provided a platform for articulating grievances and asserting rights, foreshadowing the democratic ideals that would later take root. The convening of the Estates General in 1789, during the upheaval of the French Revolution, attests to this legacy. In this instance, the Third Estate—the commoners—demanded representation, challenging the entrenched privileges of the nobility and clergy and paving the way for the end of feudalism.

Additionally, the Estates General acted as a catalyst for societal and institutional change, sparking debates on governance, taxation, and the distribution of power. The early seeds of representative governance and popular sovereignty can be discerned within its tumultuous sessions. While its immediate impact may have been limited, its legacy persists in today’s democratic institutions.

In conclusion, the Estates General stands as a testament to the complexities of medieval governance and the evolving nature of political representation. Its significance may be debated, but its impact on the historical narrative is undeniable. From its embryonic stages to its role in revolutionary transformation, it has shaped the contours of power and authority, leaving a lasting imprint on history. As we explore its significance, we are reminded of the enduring quest for representation, consensus, and the pursuit of a more just and equitable society.
