Other benefits of biodiversity include cultural, spiritual and recreational values. Species diversity then is the number of different species co-existing within a community, for example bear, humans, birds and dogs. Biodiversity plays an important role in ecosystem functions, which provide supporting, provisioning, regulating, and cultural services. California has prairies, deserts, lakes, forests and beach. The closest relations of an organism are members of its own species. In short, a population has a better chance of survival if there is more genetic diversity. The direct use of inland water biodiversity (e.g., for inland fisheries) provides food security for countless millions of the world’s poor. Biodiversity is the variety of all plants and animals (species of different flora, fauna and micro-organisms and their genes) and the ecosystem (terrestrial and aquatic) in which they live. Describe the benefits to human health of maintaining biodiversity. A nice example of species diversity can be found when looking at a lake. 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. The Importance Of Biodiversity 704 Words | 3 Pages . Bacteria, fungi and other microorganisms, bryophytes and the various plants, birds, insects, fish and humans are all the fundamental part of biodiversity. The Pacific Northwest represents a unique ecosystem. For example, our ecosystem services such as pollution breakdown and absorption and protection of water resources. Some animals like horse, camel and yak are used for transport. With less biodiversity, these connections weaken and sometimes break, harming all the species in the ecosystem… Biodiversity is important to people in many ways. Living organisms on the earth are complex, dynamic, and varies according to the earthly or the marine ecosystems. 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 … Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. Human beings benefit in many ways from biodiversity. 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. For example, the extinction of one species may cause the extinction of another. The controversy of predator decline regards the decline of predators who help the ecosystem by … 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. Biodiversity is important because it boosts ecosystem productivity where each species all have an important role to play. 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. Stories abound of the discovery of life-saving plant-derived drugs just before the last of the species was eliminated by deforestation. The Gulf Coast of Florida is another unique ecosystem with different characteristics. 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. Ecosystems are made up of abiotic (non-living, environmental) and biotic components, and these basic components are important to nearly all types of ecosystems. 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. To learn more about biodiversity, visit the Australian Museum website or read about it on Wikipedia. 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 earth itself has ecosystem diversity: for example, it has forests, oceans, deserts, wetlands and grasslands. 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. 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. Support a larger number of plant species and, therefore, a greater variety of crops. Although some ecosystems may be insensitive to species loss, due to variations in ecosystem types, or the presence of multiple species that perform a similar role, or due to their relative unimportance, or because of other abiotic factors, it is clear that higher numbers of species are needed to ensure stable provision of ecosystem services. The loss of an entire ecosystem can be socially disassembling. Biodiversity is variation at the genetic, species, and ecosystem levels. Bone, hair, skin, wool of animals and birds are the raw materials for several industries. The variation in ecosystems within a geographical location and its impact on human existence and the environment is ecosystem diversity. 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. Genetic erosion of crops is an issue of concern today. With reduced diversity in the gene pool, the chance for extinction increases. Why Is It Important to Conserve Biodiversity? The depletion of biodiversity will have profound consequences for the functioning of ecosystem services. Biodiversity and the ecosystem sustainability, Areas with the highest levels of biodiversity, 10 Endangered Plants with Medicinal Properties, nature contributes to the emotional well-being, The Importance of Indigenous Knowledge for the Modern World, medicines production of food, fiber for textiles and shelter, fuel and energy, the suppression of pests and human diseases. Biodiversity works in much the same way, with each organism and each ecosystem working together as part of one larger living system. Many of our most potent medicines are derived from plants . Likewise, it is well-documented that nature contributes to the emotional well-being of humans . Read about Biodiversity Conservation, the importance of Biodiversity, Loss of Biodiversity, and more. Utilitarian values include the many basic needs humans obtain from biodiversity such as food, fuel, shelter, and medicine. A food web is a more complex arrangement where some of the species have a couple different food options. Such changes may affect ecosystem function and the ecosystem services they provide. Another importance of biodiversity is the availability of necessary animal products like milk, meat, curd, ghee, etc. Plants, for instance, help humans by giving off oxygen. Image credit: VectorMine . Conversely, genetic diversity is significant in helping a species adapt to changes in its environment. Utilitarian values include the many basic needs humans obtain from biodiversity such as food, fuel, shelter, and medicine. It also provides services to entire ecosystems. Why Is Biodiversity Important? When we talk about ecosystem and biodiversity we need to focus both bio and non-bio (physical) factors. Nature also provides many opportunities for recreation from ziplining to canoeing. Ø This value is related primarily with functions of ecosystem. Many salient points made. Materials of daily use and decoration are also manufactured from them. 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. Ecosystems affect the biosphere, or life on earth. Many still do, but many do not. Offer environments for recreation and tourism. This is because the more equal species are in proportion to each other, the more stable it is because there are not dominant species. It includes organisms from Earth’s vastly different ecosystems, including deserts, rainforests, coral reefs, grasslands, tundra, and polar ice caps. 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. This project is no longer funded and will not be updated. 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 . 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. Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing. 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. Healthy and well-functioning freshwater, terrestrial and marine ecosystems are important for a productive and healthy environment. Dominant species may reflect an imbalance in the food chain which will likely lead to the extinction of the prey. Estimates of the number of species range from 3.6 million to over 100 million species. 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. For example, our ecosystem services such as pollution breakdown and absorption and protection of water resources. Biodiversity is categorized into species diversity, genetic diversity and ecosystem diversity. This can be done by recycling & storage of nutrients, controlling pollution, & stabilizing climate. Biodiversity underpins a range of ecosystem services. biodiversity in nature plays a vital role in balancing natural ecosystems because each organism has a specific role to play. For example, A larger number of plant species means a greater variety of crops; Greater … Most cultures, at least at some time, have recognized the importance of conserving natural resources. Based on tropical rainforests, we see why biodiversity is so crucial in maintaining an ecosystem. Climate Change Effects on the World's Biodiversity, The Loss of Biodiversity from Human Activity. When species reproduce, the genes of each mate contribute to the characteristics of the progeny. Changes in biodiversity and ecosystem services due to climate change are not all negative, with some species either thriving or adapting. The largest scale of biodiversity generally examined is ecosystem diversity. In either event, the unevenness will cause a domino effect of instability on all of the species in the ecosystem . Biodiversity And Ecosystem Stability Biodiversity is important for the health of an ecosystem. The diversity of species provides humans with a wide range of economic benefits: Wild plants and animals maintain a valuable pool of genetic variation. Download the Biodiversity notes PDF for IAS Exam. The services that humans derive from ecosystems include food, fuel, clothing, structural materials, medicines and genetic resources.
