Generally, a species is a group of similar individuals capable of interbreeding and producing offspring. This can be done by recycling & storage of nutrients, controlling pollution, & stabilizing climate. Importance of Biodiversity. Based on tropical rainforests, we see why biodiversity is so crucial in maintaining an ecosystem. A food web is a more complex arrangement where some of the species have a couple different food options. Biodiversity was discussed by the Commission on Sustainable Development on several occasions, and was one of the themes of the 2012/2013 two-year cycle. And the soil may then travel to a place where these nutrients are absorbed and used, perhaps by plants which then exhale oxygen and enrich our air. High biodiversity in an ecosystem, that is a large variety of species and genes in the ecosystem contribute to a stronger ecosystem. For example, the extinction of one species may cause the extinction of another. Plants, for instance, help humans by giving off oxygen. Loss of biodiversity may have reverberating consequences on ecosystems because of the complex interrelations among species. Biodiversity is constantly playing a vital role in the existence and sustainability of ecosystems. All species on Earth are somewhat related through genetic connections. Further, ecosystems provide crucial services such as pollination, seed dispersal, climate regulation, water purification, nutrient cycling, and control of agricultural pests. When there is a large population from which to reproduce, there can be more combinations of genes in the offspring. Let us know if you liked this article. 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]. An entire rain forest may be examined for the adverse effects on human life of its deforestation. Our biodiversity is very important to the well-being of our planet. Key Takeaways Key Points. The variation in ecosystems within a geographical location and its impact on human existence and the environment is ecosystem diversity. Biodiversity is the variety of living organisms and their interactions with each other, i.e. For example, our ecosystem services such as pollution breakdown and absorption and protection of water resources. When species reproduce, the genes of each mate contribute to the characteristics of the progeny. Read about Biodiversity Conservation, the importance of Biodiversity, Loss of Biodiversity, and more. Biodiversity is important for a few reasons. They also provide food, shade, construction material, medicines, and fiber for clothing and paper. Accordingly, no two members of the same species are exactly alike. All species, including human beings, are intricately linked by their interactions with each other and the environment… 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. 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. Wild food sources are mainly aquatic, but few are being managed for sustainability. If a lake has many different types of fish and other marine life like turtles and frogs and many different types of plants and insects, then there is a great biodiversity of genes and species all contributing to the sustainability of the ecosystem of the lake. California has prairies, deserts, lakes, forests and beach. And yet it is so complex that most of the species within it, close to 90 percent [1], remain undiscovered. Biodiversity is very important to the well-being of our planet and here’s why. Importance of Biodiversity. This could lead to the displacement of animals relying on the native plants for food or shelter. Biodiversity works in much the same way, with each organism and each ecosystem working together as part of one larger living system. Greentumble was founded in the summer of 2015 by us, Sara and Ovi. In short, a population has a better chance of survival if there is more genetic diversity. 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. Biodiversity is the foundation of ecosystem services to which human well-being is intimately linked. A nice example of species diversity can be found when looking at a lake. Importance/Significance of biodiversity: Ø Biodiversity indicates variations of life forms (species, ecosystem, biome) Ø Biodiversity indicate the health of ecosystem There are multiple examples within any region of each category of insect, bacteria, herbivore, omnivore or carnivorous predator. Conversely, genetic diversity is significant in helping a species adapt to changes in its environment. It acts as a catalyst in the role of species in an ecosystem. Its aquatic life may contribute to the quality of the soil by aerating it and enriching it with its waste and carcasses. Biodiversity is important for maintaining an important balance of the ecosystem. Why is Biodiversity Important? Provide for nutrient storage and recycling. Ø This value is related primarily with functions of ecosystem. Image credit: VectorMine . 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 … A healthy biodiversity provides many natural services that are beneficial for everyone. Changes in biodiversity can … Most cultures, at least at some time, have recognized the importance of conserving natural resources. Biodiversity is important for many reasons and they can be generally divided into two categories: the importance for ecosystems and for us. We are a couple of environmentalists who seek inspiration for life in simple values based on our love for nature. Biodiversity is important in ecosystems because it prevents extinction of species, allows organisms to adapt to changes in the environment and provides a wide range of materials and foods for survival. 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. 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. 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 … Learning Objectives. It may have cattails that filter and clean the water. life on Earth. Support a larger number of plant species and, therefore, a greater variety of crops. Only a few major crops are feeding most of the world. 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. This project is no longer funded and will not be updated. The services that humans derive from ecosystems include food, fuel, clothing, structural materials, medicines and genetic resources. Increase ecosystem productivity; each species in an ecosystem has a specific niche—a role to play. This is because species in an ecosystem depend upon each other for food, keeping birth and death rates in a balance that is sustainable for the ecosystem. Why Is It Important to Conserve Biodiversity? More genetic defects are caused by inbreeding. The controversy of predator decline regards the decline of predators who help the ecosystem by … Until that time, it had been widely believed that Amazonia was the richest ecosystem on earth. 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. Since each species has a role to play, a diverse ecosystem allows them to interact and reach symbiosis. Biodiversity role in Ecosystem related functions: It also plays an important role in ecosystem-related functions, which provide ancillary, regulation, and cultural services.These services are essential for human welfare. Biodiversity And Ecosystem Stability Biodiversity is important for the health of an ecosystem. biodiversity in nature plays a vital role in balancing natural ecosystems because each organism has a specific role to play. 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. Such changes may affect ecosystem function and the ecosystem services they provide. 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]. increased lianas in tropical forest). 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. Genes are the bits of biochemical information that partly determine how an organism looks, behaves, and live… Bacteria, fungi and other microorganisms, bryophytes and the various plants, birds, insects, fish and humans are all the fundamental part of biodiversity. Our environments and the species that live in them need a diverse population of genes. 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. Before getting into Tourism and Biodiversity, it is crucial to know what is tourism and Bio-diversity. 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 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. 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. An excellent article. Ecosystem diversity is also used to refer to the number and variety of interactions in a certain area. Biodiversity is the ‘library’ of species and genetic information that allows the Earth’s systems to function. > Biodiversity role in Ecosystem related functions- It also plays an important role in ecosystem-related functions, which provide ancillary, regulation, and cultural services. Changes in biodiversity and ecosystem services due to climate change are not all negative, with some species either thriving or adapting. Biodiversity plays a crucial role in human nutrition through its influence on world food production, as it ensures the sustainable productivity of soils and provides the genetic resources for all crops, livestock, and marine species harvested for food. Read more about us. 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. 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. Members of a species share genes. Bone, hair, skin, wool of animals and birds are the raw materials for several industries. 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. The closest relations of an organism are members of its own species. 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. An aesthetic appreciation of biodiversity itself has also been documented. Economic Benefits of Biodiversity . 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. 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. 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. Millions of species inhabit land, freshwater, and ocean ecosystems. Ecosystems are made up of abiotic (non-living, environmental) and biotic components, and these basic components are important to nearly all types of ecosystems. To learn more about biodiversity, visit the Australian Museum website or read about it on Wikipedia. Human beings benefit in many ways from biodiversity. A healthy ecosystem stems from rich biodiversity. Healthy ecosystems and rich biodiversity: How do we replace lost biodiversity? All species, including humans, are adversely affected by the loss of species 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. Should a drought, pest or disease threaten one of these crops, the entire world’s food supply will diminish appreciably. 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]. The Importance of Biodiversity to Human Life. One of the most important reasons we should continue to work on preserving … Offer environments for recreation and tourism. Over millions of years many different species of plants and animals have come to live in the same habitats. Biodiversity plays an important role in protecting the water resources. Healthy and well-functioning freshwater, terrestrial and marine ecosystems are important for a productive and healthy environment. 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. 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 [20]. The Pacific Northwest represents a unique ecosystem. 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. Biodiversity changes affect ecosystem functioning and significant disruptions of ecosystems can result in life sustaining ecosystem goods and services. For instance, the role of native insects in pollination, which is critical for agriculture, has been highlighted in recent years. Another importance of biodiversity is the availability of necessary animal products like milk, meat, curd, ghee, etc. Living organisms on the earth are complex, dynamic, and varies according to the earthly or the marine ecosystems. Biodiversity is a community of all the living organisms on the earth and the diversity among them from all the ecosystems. For example, A larger number of plant species means a greater variety of crops; Greater … Biodiversity is a reservoir of resources for the manufacture of food, cosmetic products and pharmaceuticals. This means we value biodiversity both for what it provides to humans, and for the value it has in its own right. And the warm waters of the Indian and Pacific Oceans are considered to have the most diverse marine environments [19]. Biodiversity plays an important role in ecosystem functions, which provide supporting, provisioning, regulating, and cultural services. Biodiversity is important to most aspects of our lives. These services are essential for human welfare. Biodiversity is the amount of variety of life on Earth. 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. Biodiversity can occur in a very small particular area or in a very large area like the ocean. Many salient points made. The Census of Marine Life puts the number at 8.7 million, give or take [2]. 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. The more links in the food chain there are, like more fish for the bear, the healthier everyone up the chain can be. With reduced diversity in the gene pool, the chance for extinction increases. 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 ecosystem supports the services without which humans cannot survive. Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing. The damage already done to these unique and essential biomes could be a sign of a … Coral reefs are important to the ecosystem because they are the pillars on which marine and coastal ecosystems are built. This is because the more equal species are in proportion to each other, the more stable it is because there are not dominant species. 1. All forms of life from microbes to plants to humans contain genes. 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. It also provides services to entire ecosystems. 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. Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. Biodiversity is what allows ecosystems to work and flourish. Most of these ecosystem services cannot be replaced by human technology, at any cost. Maintaining biodiversity of natural ecosystems is one of the most important problems and tasks for people in the 21st century. 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. Utilitarian values include the many basic needs humans obtain from biodiversity such as food, fuel, shelter, and medicine. Importance of Biodiversity There are numerous reasons deeming biodiversity significant. Why is diversity important in an ecosystem? Ecosystem Ecology looks at energy transformations and biogeochemical cycling within ecosystems. 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]. Loss of biodiversity threatens these ecosystem services and risks making food production more expensive or impossible. Download the Biodiversity notes PDF for IAS Exam. Climate Change Effects on the World's Biodiversity, The Loss of Biodiversity from Human Activity. Access to a sufficiency of a nutritious variety of food is a fundamental determinant of health. Ø Biodiversity is very essential for: Ecological balance, Constancy of climatic features and Soil maintenance. It includes organisms from Earth’s vastly different ecosystems, including deserts, rainforests, coral reefs, grasslands, tundra, and polar ice caps. | Greentumble The Gulf Coast of Florida is another unique ecosystem with different characteristics. When species are examined for biodiversity, three elements are looked at: The greater the variety of species, the healthier the ecosystem is. Biodiversity is the extraordinary variety of life on Earth—from genes and species to ecosystems and the valuable functions they perform. 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. A wide variety of species will cope better with threats than a limited number of them in large populations. Because people evolve with their environments, their history and identity is embedded there. 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. When we talk about ecosystem and biodiversity we need to focus both bio and non-bio (physical) factors. 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. 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. The main threats facing biodiversity globally are: destruction, degradation and fragmentation of habitats ; reduction of individual survival and reproductive rates through exploitation, pollution and introduction of alien species. Nutritional impact of biodiversity. The Pacific Northwest represents a unique ecosystem. Biodiversity is important in human-managed as well as natural ecosystems. 17 December, 2019 0 Comments "Tourism and Importance of Biodiversity . Inland water biodiversity is critically important to poverty reduction and the achievement of human development targets. Ecosystem diversity level: Ecosystem consists of all the animals, microorganisms, plants as well as the physical aspects of the area. Genes carry traits and characteristics. Biodiversity plays an important role in ecosystem functions, which provide supporting, provisioning, regulating, and cultural services. Human Health and Biodiversity. We also need to protect our water resources, protecting soil & maintaining eco-balance. This study evaluates the importance of biodiversity for multiple ecosystem functions in a tropical human‐modified landscape. 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. Maintaining biodiversity ultimately helps maintain of human health; many medicines are derived from plants and, recently, animal toxins. 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. Ecosystems provide ecosystem services that support human agriculture: pollination, nutrient cycling, pest control, and soil development and maintenance. High biodiversity in an ecosystem, that is a large variety of species and genes in the ecosystem contribute to a stronger ecosystem. Biodiversity is an essential part of the solution to climate change. Biodiversity is important because it boosts ecosystem productivity where each species all have an important role to play. The Gulf Coast of Florida is another unique ecosystem with different characteristics. Biodiversity provides ecosystem services, food, medicines and natural products, economic benefits and natural beauty. Materials of daily use and decoration are also manufactured from them. It is the number of different species of plants, animals, and microorganisms. This can be done by recycling & storage of nutrients, controlling pollution, & stabilizing climate. 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 Importance of Biodiversity Biodiversity is the amount of variety of life on Earth. The diversity linked to micro-organisms, different plants and animals is included in biodiversity. Some animals like horse, camel and yak are used for transport. Many still do, but many do not. 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. Greentumble is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. 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 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. 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 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. The Importance Of Biodiversity 1058 Words | 5 Pages Biodiversity is a balance critical to the ecosystem. This includes the deep feeling of being interconnected with other species on earth. The loss of an entire ecosystem can be socially disassembling. 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. Bio-diversity is the diversity among living organisms, including marine, terrestrial, and other aquatic ecosystems. Biodiversity is categorized into species diversity, genetic diversity and ecosystem diversity. 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]. 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.
