what is the importance of biodiversity to ecosystem

2. California has prairies, deserts, lakes, forests and beach. Antibiotics, fungicides, anticancer drugs, blood-clotting agents and thinners, anesthetics, cardiac regulators and fever suppressants are among the drugs we have obtained from wild biodiversity [8]. Human life relies on our ecosystems providing the life-sustaining services of providing oxygen, detoxifying our soil and water, providing materials for clothing and shelter and providing our food and the nutrients we require. E.O. Genetic erosion of crops is an issue of concern today. It is commonly believed that the more diversity of life within an ecosystem the stronger it is and the better able it is to sustain itself in the face of external stresses. The importance of biodiversity for numerous industries across Australia has not been quantified, but recent issues exemplify our ongoing reliance on functioning ecosystems to maintain key processes that, in the past, may have been taken for granted. Ecosystems affect the biosphere, or life on earth. Biodiversity is important for maintaining an important balance of the ecosystem. When species are examined for biodiversity, three elements are looked at: The greater the variety of species, the healthier the ecosystem is. Energy is continually input into an ecosystem in the form of light energy, and some energy is lost with each transfer to a higher … Plants, for instance, help humans by giving off oxygen. Why is Biodiversity Important? The diversity of species provides humans with a wide range of economic benefits: Wild plants and animals maintain a valuable pool of genetic variation. Estimates of the number of species range from 3.6 million to over 100 million species. It includes organisms from Earth’s vastly different ecosystems, including deserts, rainforests, coral reefs, grasslands, tundra, and polar ice caps. The Census of Marine Life puts the number at 8.7 million, give or take [2]. For UPSC 2021 preparation, follow BYJU'S. Bio-diversity and Tourism and is interrelated to each other, and there is no denying of the fact that tourism development is directly related to healthy ecosystems. Generally, a species is a group of similar individuals capable of interbreeding and producing offspring. Species diversity then is the number of different species co-existing within a community, for example bear, humans, birds and dogs. Stories abound of the discovery of life-saving plant-derived drugs just before the last of the species was eliminated by deforestation. Many still do, but many do not. Increase ecosystem productivity; each species in an ecosystem has a specific niche—a role to play. The largest scale of biodiversity generally examined is ecosystem diversity. Learning Objectives. Support a larger number of plant species and, therefore, a greater variety of crops. Having a rich variety of ecosystems, what biologists call ecosystem diversity, constitutes another important level of biodiversity. Biodiversity also benefits the humans in numerous aspects. A food web is a more complex arrangement where some of the species have a couple different food options. "Biodiversity influences ecosystem services, that is, the benefits provided by ecosystems to humans, that contribute to making human life … Biodiversity is the amount of variety of life on Earth. The list of services ecosystems perform for us is extensive and includes: While the medicinal value of plants is mentioned above as one of the services provided by an ecosystem, this service deserves specific attention. Provide for nutrient storage and recycling. Some animals like horse, camel and yak are used for transport. Biodiversity plays an important role in ecosystem functions, which provide supporting, provisioning, regulating, and cultural services. The ecosystem supports the services without which humans cannot survive. Preserving biodiversity at any level may not seem like a big deal -- at first. Biodiversity is very important to the well-being of our planet and here’s why. Ecological life support—biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. Ø This value is related primarily with functions of ecosystem. Why Is Biodiversity Important? All species on Earth are somewhat related through genetic connections. The lake may be important to humans as a food source, an income source from for example, a kayak rental business and as a source of recreation. Crops livestock, fishery, and forests are a rich source of food. Tourism and Importance of Biodiversity; Author GPTV. A wider range of genetic diversity allows species to build resistances to diseases, as shown in studies on leaf-cutting ant colonies and fruit flies, and strengthens the possibility that at least some individuals will survive, and by making them less susceptible to inherited disorders. Before getting into Tourism and Biodiversity, it is crucial to know what is tourism and Bio-diversity. With reduced diversity in the gene pool, the chance for extinction increases. When there is a large population from which to reproduce, there can be more combinations of genes in the offspring. Biodiversity is an essential part of the solution to climate change. When species reproduce, the genes of each mate contribute to the characteristics of the progeny. The loss of an entire ecosystem can be socially disassembling. More formally, biodiversity is comprised of several levels, starting with genes, then individual species, then communities of creatures and finally entire ecosystems, such as forests or … These services are essential for human welfare. Healthy and well-functioning freshwater, terrestrial and marine ecosystems are important for a productive and healthy environment. Biodiversity loss also means that we are losing, before discovery, many of nature's chemicals and genes, of the kind that have already provided humankind with enormous health benefits. Biodiversity is important for many reasons and they can be generally divided into two categories: the importance for ecosystems and for us. Biodiversity can occur in a very small particular area or in a very large area like the ocean. The Sustainable Development Goal 15 of the 2030 Agenda for Sustainable Development is devoted to “protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss”.. At the Rio+20 Conference, Member States reaffirmed, through paragraphs 197- 204 of the … Changes in biodiversity can generally alter ecosystem functioning.Due to which there will be some changes in human life. Biodiversity is a reservoir of resources for the manufacture of food, cosmetic products and pharmaceuticals. The more links in the food chain there are, like more fish for the bear, the healthier everyone up the chain can be. If there are more types of plants, there can be more food with a variety of nutritional content, as well as a better selection of effective medicines. Dominant species may reflect an imbalance in the food chain which will likely lead to the extinction of the prey. This could lead to the displacement of animals relying on the native plants for food or shelter. For example, an ecosystem being studied may be as small as a patch of lichen on a rock or patch of moss on a tree trunk or it could be an entire coral reef and all of the life that it sustains and that sustain it [16]. With less biodiversity, these connections weaken and sometimes break, harming all the species in the ecosystem… Biodiversity is important to people in many ways. Biodiversity provides ecosystem services, food, medicines and natural products, economic benefits and natural beauty. Read about Biodiversity Conservation, the importance of Biodiversity, Loss of Biodiversity, and more. Biodiversity is important in human-managed as well as natural ecosystems. Biodiversity is important for a few reasons. The depletion of biodiversity will have profound consequences for the functioning of ecosystem services. Benefits of Biodiversity to the Ecosystem . One overriding importance is that biodiversity is responsible for the continuity of the planet because it supports majority of the vital environmental life cycles such as the oxygen cycle, the water cycle , and the nitrogen cycle just to mention a few. The more links that exist in the web the more stable the ecosystem as the removal of one link will not have a dramatic effect if there are other links that can fill the void. Many of our most potent medicines are derived from plants [6]. Our environments and the species that live in them need a diverse population of genes. Some economic and social arguments further illustrate the importance of biodiversity: Maintaining biodiversity of natural ecosystems is one of the most important problems and tasks for people in the 21st century. Importance of Biodiversity. Ecological diversity within an ecosystem is more diverse when it contains varied topography, allowing more places for shelter and for escape, a lot of sunlight and rainfall, allowing for more rapid growth of plants as a food source and stable temperatures, making adaptation easier for species. We are a couple of environmentalists who seek inspiration for life in simple values based on our love for nature. Biodiversity is categorized into species diversity, genetic diversity and ecosystem diversity. Ø Biodiversity is very essential for: Ecological balance, Constancy of climatic features and Soil maintenance. A diverse ecosystem is more productive and can withstand environmental stress. 3. It also provides services to entire ecosystems. For example, our ecosystem services such as pollution breakdown and absorption and protection of water resources. Describe the benefits to human health of maintaining biodiversity. Let us know if you liked this article. For example, our ecosystem services such as pollution breakdown and absorption and protection of water resources. Biodiversity is important for maintaining an important balance of the ecosystem. Until that time, it had been widely believed that Amazonia was the richest ecosystem on earth. Offer environments for recreation and tourism. Biodiversity is the variety of all living things: the different plants, animals and microorganisms, the different genetic information they contain, and the varied ecosystems they form. But the findings showed that in fact there was a greater number of diverse species in tropical forests over a greater distance in Panama [18]. The Pacific Northwest represents a unique ecosystem. Most of these ecosystem services cannot be replaced by human technology, at any cost. Scientists examine the amount of biodiversity of life at three levels: the genetic level; the species level; and, at the level of ecosystems sustaining the life within them. Human life relies on our ecosystems providing the life-sustaining services of providing oxygen, detoxifying our soil and water, providing materials for clothing and shelter and providing our food and the nutrients we require. Over millions of years many different species of plants and animals have come to live in the same habitats. Based on tropical rainforests, we see why biodiversity is so crucial in maintaining an ecosystem. Introduction 1.1 Background Biodiversity is the term used to encompass the variety of all living organisms on Earth, including their genetic diversity, species diversity and the diversity of ecosystems. Biodiversity is the extraordinary variety of life on Earth—from genes and species to ecosystems and the valuable functions they perform. Intact or well-connected ecosystems provide habitat for native plants and animals, including humans, and provide ecosystem services such as clean water for drinking and fertile soils and oceans for production. Changes in biodiversity and ecosystem services due to climate change are not all negative, with some species either thriving or adapting. biodiversity in nature plays a vital role in balancing natural ecosystems because each organism has a specific role to play. Ecosystem function is important for supporting plant and animal communities, and ensuring the long-term survival of human populations. There are multiple examples within any region of each category of insect, bacteria, herbivore, omnivore or carnivorous predator. The Pacific Northwest represents a unique ecosystem. > Biodiversity role in Ecosystem related functions- It also plays an important role in ecosystem-related functions, which provide ancillary, regulation, and cultural services. The variation in ecosystems within a geographical location and its impact on human existence and the environment is ecosystem diversity. To be considered sustainable an ecosystem must be able to maintain these processes over time and in the face of external stresses that may occur like fires or pollution. And the warm waters of the Indian and Pacific Oceans are considered to have the most diverse marine environments [19]. We also need to protect our water resources, protecting soil & maintaining eco-balance. When we talk about ecosystem and biodiversity we need to focus both bio and non-bio (physical) factors. The Importance Of Biodiversity 1058 Words | 5 Pages Biodiversity is a balance critical to the ecosystem. Healthy marine ecosystems are important for society since they provide services including food security, feed for livestock , raw materials for medicines, building materials from coral rock and sand, and natural defenses against hazards such as coastal erosion and inundation. Economic Benefits of Biodiversity . In short, a population has a better chance of survival if there is more genetic diversity. Further, ecosystems provide crucial services such as pollination, seed dispersal, climate regulation, water purification, nutrient cycling, and control of agricultural pests. Human Health and Biodiversity. The Gulf Coast of Florida is another unique ecosystem with different characteristics. Seventy percent of the plants identified as having anti-cancer characteristics by the US National Cancer Institute are found only in the tropical rainforest [9]. In essence, any reduction of the diversity of life, whether by human hands or by natural causes, weakens the links that exist among species and habitats. Loss of biodiversity eventually threatens other species we do not impact directly because of their interconnectedness; as species disappear from an ecosystem other species are threatened by the changes in available resources. Biodiversity is what allows ecosystems to work and flourish. Bio-diversity is the diversity among living organisms, including marine, terrestrial, and other aquatic ecosystems. To learn more about biodiversity, visit the Australian Museum website or read about it on Wikipedia. Loss of biodiversity may have reverberating consequences on ecosystems because of the complex interrelations among species. Members of a species share genes. Decisions humans make that influence biodiversity affect the well-being of themselves and others. Biodiversity underpins a range of ecosystem services. Having a rich variety of ecosystems, what biologists call ecosystem diversity, constitutes another important level of biodiversity. Provide more medicinal resources and pharmaceutical drugs. This can be done by recycling & storage of nutrients, controlling pollution, & stabilizing climate. Biodiversity is defined as "the variety of life and it's processes," which can be thought of as the diverse and richness of life that exists on earth. With more variations in the genes it is more likely that a member of the species has genes that are well-suited or resistant to the changes being faced, whether it is a poorer air quality or a spreading disease. This study evaluates the importance of biodiversity for multiple ecosystem functions in a tropical human‐modified landscape. Ecosystem diversity looks at the number and variability of ecosystems in an area. The direct use of inland water biodiversity (e.g., for inland fisheries) provides food security for countless millions of the world’s poor. What is the key to their success?https://t.co/179Z5AnYTw pic.twitter.com/Qw7hXuBBQK. Biodiversity plays an important role in protecting the water resources. Since rainforests have huge ranges of plants, many insects or animals will have more diverse preys. This project is no longer funded and will not be updated. Or a dominant species could be an invasive plant that will overtake the native plants in the competition for soil. Likewise, it is well-documented that nature contributes to the emotional well-being of humans [11]. The goal is to save the seeds of crops best able to provide high yield of nutritional content and to survive climate change and pests and disease [14]. High biodiversity in an ecosystem, that is a large variety of species and genes in the ecosystem contribute to a stronger ecosystem. Climate Change Effects on the World's Biodiversity, The Loss of Biodiversity from Human Activity. 1. Biodiversity And Ecosystem Stability Biodiversity is important for the health of an ecosystem. Utilitarian values include the many basic needs humans obtain from biodiversity such as food, fuel, shelter, and medicine. Utilitarian values include the many basic needs humans obtain from biodiversity such as food, fuel, shelter, and medicine. It is the number of different species of plants, animals, and microorganisms. A healthy biodiversity provides many natural services that are beneficial for everyone. Ecosystem Ecology looks at energy transformations and biogeochemical cycling within ecosystems. An analysis on the importance of biodiversity in an ecosystem as shown by the gray wolf extirpation and reintroduction in Yellowstone Park The extirpation of the grey wolf (Canis lupus) in Yellowstone Pak is a prime example of the impact of biodiversity loss, specifically a keystone species, on a terrestrial ecosystem. Biodiversity is variation at the genetic, species, and ecosystem levels. The earth itself has ecosystem diversity: for example, it has forests, oceans, deserts, wetlands and grasslands. Changes in the composition of ecosystems have also been observed (e.g. Biodiversity is very important to the well-being of our planet and here’s why. And the more closer a species is related to another, the more genetic information the two species will share. In either event, the unevenness will cause a domino effect of instability on all of the species in the ecosystem [20]. Other benefits of biodiversity include cultural, spiritual and recreational values. If a fire tears through a forest where only one species exists and is wiped out by the fire, the forest ecosystem is less likely to deal with this loss than if only one out of 20 species disappeared. Because people evolve with their environments, their history and identity is embedded there. Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing. An aesthetic appreciation of biodiversity itself has also been documented. A healthy biodiversity provides many natural services that are beneficial for everyone. Its aquatic life may contribute to the quality of the soil by aerating it and enriching it with its waste and carcasses. This includes the deep feeling of being interconnected with other species on earth. Given the interconnected nature of ecosystems, where a change in one area can have far reaching effects elsewhere, it is therefore vital to maintain as great a variety of species as possible in order to ensure the continued healthy existence of the planet. Not surprisingly, given the abundance of sunlight and rainfall and varied topography, the highest levels of biodiversity on our planet are in our rainforests. Nature also provides many opportunities for recreation from ziplining to canoeing. Our biodiversity is very important to the well-being of our planet. All species, including human beings, are intricately linked by their interactions with each other and the environment… Bone, hair, skin, wool of animals and birds are the raw materials for several industries. Maintaining biodiversity ultimately helps maintain of human health; many medicines are derived from plants and, recently, animal toxins. Many salient points made. Biodiversity is also key for the continued provision of ecosystems services it provides, which serve both humans and the systems themselves, although the term is largely used in relation to the benefits reaped by us. An ecosystem will have a higher productivity rate and more robust ecological processes when more different life forms can thrive and survive. They clean up our water and protect our coasts. Ecosystems are made up of abiotic (non-living, environmental) and biotic components, and these basic components are important to nearly all types of ecosystems. While heavy machinery keeps spraying #monocrops with #pesticides and #fertilizers, millions of #family #farmers are applying agroecological approaches to redress those impacts and revive #rural areas. Conversely, genetic diversity is significant in helping a species adapt to changes in its environment. Greentumble was founded in the summer of 2015 by us, Sara and Ovi. Genes are the bits of biochemical information that partly determine how an organism looks, behaves, and live… At the World Summit on Sustainable Development, held in Johannesburg 2002, biological diversity was addressed in Chapter IV, paragraph 44, of the outcome of the Summit, the Johannesburg Plan of Implementation. A healthy ecosystem stems from rich biodiversity. increased lianas in tropical forest). Medical Discoveries. It acts as a catalyst in the role of species in an ecosystem. One overriding importance is that biodiversity is responsible for the continuity of the planet because it supports majority of the vital environmental life cycles such as the oxygen cycle, the water cycle, and the nitrogen cycle just to mention a few. Key Takeaways Key Points. Access to a sufficiency of a nutritious variety of food is a fundamental determinant of health. Quick Navigation for The Importance of Biodiversity, [1] Wilson, Edward O., The Future of Life, A.A. Knopf, NY, NY 2002, p.3. All species, including humans, are adversely affected by the loss of species diversity. Biodiversity is important to most aspects of our lives. Biodiversity plays an important role in ecosystem functions, which provide supporting, provisioning, regulating, and cultural services. Ninety percent of the world’s food supply is from only 100 crops and three: rice, maize and wheat account for almost 70 percent of the calories people derive from plants [13]. Biodiversity is measured not only by the richness of an area in the number of diverse species living there, but it also considers the evenness of the species. Importance of Biodiversity. The connectedness of ecosystems and biomes means that all organisms in any given system must work together and balance each other in order to maintain a healthy system. It includes al the ecosystems, whether it … There are numerous reasons deeming biodiversity significant. The term biodiversity (from the phrase “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life. Most cultures, at least at some time, have recognized the importance of conserving natural resources. Wild food sources are mainly aquatic, but few are being managed for sustainability. Download the Biodiversity notes PDF for IAS Exam. We found that dominance is potentially more important than species traits in determining species functionality; because of the strong effect of dominance in secondary forests, only a small subset of the dominant species matters for different functions. For example, biodiversity can occur in a very small aquarium where there are few small fish or can occur in a large ocean where whales and sharks like huge fish live with other aquatic animals. The services that humans derive from ecosystems include food, fuel, clothing, structural materials, medicines and genetic resources. Sustainability is the ability of the ecosystem to maintain its ecological processes, the composting of debris into soil, the exchange of carbon and air, the production of rainfall, photosynthesis, the life-giving processes required to maintain life as we know it on earth. Changes in biodiversity can … It is the number of different species of plants, animals, and microorganisms. Diversity is important for species in order to maintain resilience against unexpected events, such as sudden climate changes or natural disasters, like forest fires or floods. Ecosystem diversity is also used to refer to the number and variety of interactions in a certain area. Importance of Biodiversity. An entire rain forest may be examined for the adverse effects on human life of its deforestation. Plant-derived drugs are anticipated to account for 39.2 billion dollars in sales by 2022 and botanical drugs to $425 million by 2022 [7]. Biodiversity changes affect ecosystem functioning and significant disruptions of ecosystems can result in life sustaining ecosystem goods and services. A study of ecosystem diversity looks at these different ecosystems within the region and considers their sustainability, their impact on the surrounding environment and possibly even their impact on human existence. All forms of life from microbes to plants to humans contain genes. One of the most important reasons we should continue to work on preserving … More genetic defects are caused by inbreeding. Ecosystem diversity level: Ecosystem consists of all the animals, microorganisms, plants as well as the physical aspects of the area. We are working hard to improve our content. life on Earth. Biodiversity is important to people because we depend on other species and the ecosystems they create. Nutrition and biodiversity are linked at many levels: the ecosystem, with food production as an ecosystem service; the species in the ecosystem and the genetic diversity w… Genes carry traits and characteristics. Biodiversity is important to the survival and welfare of human populations because it has impacts on our health and our ability to feed ourselves through agriculture and harvesting populations of … Biodiversity is important because it boosts ecosystem productivity where each species all have an important role to play. For instance, the role of native insects in pollination, which is critical for agriculture, has been highlighted in recent years. We also need to protect our water resources, protecting soil & maintaining eco-balance. Living organisms on the earth are complex, dynamic, and varies according to the earthly or the marine ecosystems. Biodiversity works in much the same way, with each organism and each ecosystem working together as part of one larger living system. The problem is that we don’t know what we are losing, especially when it comes to life in the rainforest, where so many species have adapted amazing defenses to predators, pests, infections and diseases over thousands of years, defenses that we humans might use in our fight against cancer and other serious diseases [10]. The controversy of predator decline regards the decline of predators who help the ecosystem by … Image credit: VectorMine . Our goal is to inspire people to change their attitudes and behaviors toward a more sustainable life. The most detailed scientific study of the world’s greatest biodiversity was compiled by The Center for Tropical Forest Science, a consortium of forestry agencies, universities, research institutes and other nongovernmental agencies and published by the Smithsonian Institution in 2002. Biodiversity is constantly playing a vital role in the existence and sustainability of ecosystems. Concerned about the rapidly increasing loss of genetic diversity the UN Food and Agricultural Organization supports a trust of diverse seed collections around the world to maintain food security. Loss of biodiversity eventually threatens other species we do not impact directly because of their interconnectedness; as species disappear from an ecosystem other species are threatened by the changes in available resources.
