    why is ecosystem diversity important

    To print all information (e.g. Appreciating diversity is important as this is what forms the societies that we live in. diversity within a species allows for the mixing of genes so that the organisms don't all wind up with one genotype and be subject to death with a single environmental change. Naturally, those who benefit from the current system may be hostile to such changes, especially if it may mean they might lose out. Learn. Some have termed this Gaia. However, for similar information, you could look at Consequences of changing biodiversity, Nature 405, 234 - 242, 11 May 2000 and Causes, consequences and ethics of biodiversity, Nature 405, 208–211, 11 May 2000. Biodiversity plays significant role in soil formation and its conservation. Bookmark or share this with others using some popular social bookmarking web sites: Copy/paste the following HTML code to your page: Anup Shah, Why Is Biodiversity Important? It is the variation in the ecosystems found in a region or the variation in ecosystems over the whole planet. 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. Resources that could be available more indefinitely, become finite because of our inability or unwillingness to change. Ecosystem diversity. Planting and protecting nearly 12,000 hectares of mangroves in Vietnam costs just over a million dollars but saved annual expenditures on dyke maintenance of well over seven million dollars. Biodiversity is very important to the well-being of our planet and here’s why. Benefits that are felt with a long-term horizon (e.g. This also has a negative impact on the environment, perhaps partly formed by outdated-views that predators are harmful for other wildlife. What is the point in preserving endangered species that have no practical use to humans, apart from their aesthetic appeal or their intellectual interest to biologists? However, while commercial entities can exploit resources elsewhere, local fishermen will go out of business and the poorer will likely go hungry (as also detailed on this site’s section on biodiversity). food sources must be diverse because of each food type and the type of food/energy received from this food. Some products derived from genetic resources. In effect, as TEEB, and many others before have argued, a key challenge will be adapting our economic systems to integrate sustainability and human well-being as well as other environmental factors to give us truer costs (after all, market systems are supposed to work when there is full availability of information). Running out of resources should therefore be averted. Where possible, alternative links are provided to backups or reposted versions here. Humans rely on ecosystems for many functions. Ecosystem Productivity. 2. A study in the journal Science, notes that these large animals — such as lions, leopards, wolves and bears — are in decline, due to declining habitats and persecution by humans.. The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth. Nature can often be surprisingly resilient, often without the need for human interventions. Being against prevailing thought, they would not agree. Biodiversity is important because it provides biological resources, such as food and medicine, and ecosystem services, such as protection of water, soil, climate and nutrients. On a large scale for example plants have diversity to prevent them from being wiped out by a parasitic attack or something. 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. Add another link to more information about importance of biodiversity. Bees provide enormous benefits for humankind as another example. A healthy biodiversity provides many natural services that are beneficial for everyone. 19 Jan. 2014. An ecosystem will have a higher productivity rate and more robust ecological processes when more different life forms can thrive and survive. It promotes various food chains and food webs. 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. Biodiversity, short for biological diversity, is the term we use for the variety of animals, plants, fungi, bacteria, and other intertwined life forms within any ecosystem… “from towering redwood trees to tiny, single-cell algae that are impossible to see without a microscope.”. Involved in the recycling of nutrients between biotic and abiotic components. The Pacific Northwest represents a unique ecosystem. Spell. The cost of replacing these (if possible) would be extremely expensive. Other wildlife grew in numbers and the ecosystem was generally back in balance. 1. The relationship between soil, plants, bacteria and other life is also referred to as the nitrogen cycle: As an example, consider all the species of animals and organisms involved in a simple field used in agriculture. Researchers are finding reasons for the massive decline hard to pinpoint, but suspect a combination of various diseases, environmental pollution, environmental degradation (leading to less diversity for bees to feed from, for example) and farming practices (such as pesticides, large monoculture cropping, etc). For example, our ecosystem services such as pollution breakdown and absorption and protection of water resources. For more information on this question, visit some of the following links. All species, even those living in the most remote parts of the planet, are part of a wider ecosystem, both relying on and affecting other life forms within their biome (a term for the community of life or habitat where different species live). Each ecosystem provide different habitats that can essential for a species's life cycle. costs that have to be borne by society from ignored factors, or social costs). (2006) from public companies alone, Many products derived from genetic resources (enzymes, microorganisms), Personal care, Botanical and food & Beverage industries. Tense postgame handshake between college coaches Having a rich variety of ecosystems, what biologists call ecosystem diversity, constitutes another important level of biodiversity. The fact that within a forest, pond or sea there are countless different animals, plants, fish, birds and so on all living together. Side NoteUnfortunately the original link to the Nature.com article no longer works, since their site redesign, and I had not noted the publication details. Ecosystem diversity is very important because all life forms on earth depend on each other. These ecosystems are complex, which means they function best, and are more resilient to the effects of climate change, when all the pieces of the ecosystem are in place — meaning the biodiversity is intact. Values that are not overtly part of a financial equation are too often ignored. It was noted earlier that ecosystems provide many services to us, for free. 21-year-old arrested in Nashville nurse slaying: Police. Human intervention to perform the same services would be more costly. The biodiversity of an ecosystem is important because it stabilises the whole system where life is present. 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. Bees are more important than poultry in terms of human nutrition. So biologists are looking at these processes in more depth to see if they can reproduce or enhance such capabilities. “Give a man a fish; you have fed him for today. And as we start destroying, reducing and isolating habitats, the chances for interaction from species with a large gene pool decreases. Web. Biodiversity is important because it clears out our water, changes out climate, and provides us with food. Biodiversity is important because it boosts ecosystem productivity where each species all have an important role to play. In the mid-1990s, the Institute for Economic Democracy calculated that as much as half the American economy constituted of wasted labor, wealth and resources (book: World’s Wasted Wealth, II — see sample chapter). For a number of years now, scientists have been looking more and more at nature to see how various species work, produce, consume resources, trying to mimic the amazing feats that millions of years of evolution has produced. The three types of biodiversity (species, genetic, and ecosystem) help keep a healthy and sustainable ecosystem and environment for a long period of time. The benefits of these silent parts of our economy is also summarized in these videos by TEEB’s Pavan Sukhdev: The BBC notes that biodiversity is fundamental to economics. As a result, resources are supposedly infinite. The variety of life on Earth, its biological diversity is commonly referred to as biodiversity. Land that is used to produce unhealthy or marginally nutritious items (e.g. A healthy ecosystem stems from rich biodiversity. There are 130,000 plants for example for which bees are essential to pollination, from melons to pumpkins, raspberries and all kind of fruit trees — as well as animal fodder — like clover. Explanation: As summarized from Vandana Shiva, Stolen Harvest (South End Press, 2000), pp 61–62: Shiva, a prominent Indian scientist and activist goes on to detail the costs associated with destroying this natural diversity and traditional farming techniques which recognize this, and replacing this with industrial processes which go against the nature of diversity sustainability. An example from the seas (originally mentioned here years ago but removed because the link to the story no longer worked), was described by National Geographic Wild in a program called, A Life Among Whales (broadcast June 14, 2008). Why is Biodiversity Important? The values of other ecosystem services are generally not reflected in markets apart from a few exceptions (such as tourism). They can also overlook local public benefits … in favor of private benefits …, even when local livelihoods are at stake, or focus on short-term gains to the detriment of the sustained supply of benefits over time…. A chain of events eventually came full circle and led to a loss of jobs: Three quarters of the world’s big carnivores are in decline. Why do we need to protect biodiversity? Teach a man to fish; and you have fed him for a lifetime.” — Old Chinese Saying. Add another link to more information about importance of biodiversity. Read on, as we’ll explore the reasons why preserving biodiversity is such an important task. As German bee expert Professor Joergen Tautz from Wurzburg University adds: Bees are vital to bio diversity. Medicinal resources and pharmaceutical drugs, Diversity in genes, species and ecosystems, Cattle waste feeds the soil that nourish the crops, Crops, as well as yielding grain also yield straw, Crops are therefore food sources for humans and animals, Bacteria feed on the cellulose fibers of straw that farmers return to the soil, Amoebas feed on bacteria making lignite fibers available for uptake by plants, Algae provide organic matter and serve as natural nitrogen fixers, Rodents that bore under the fields aerate the soil and improve its water-holding capacity. As just one small example, some spiders can produce their silk with a higher tensile strength than many alloys of steel even though it is made of proteins. Discover the Importance of India. Importance of Ecosystem: It provides habitat to wild plants and animals. 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. Ecosystem diversity. Our eagle example also demonstrates another aspect of diversity. These words sum up why biodiversity is so important. Ecosystems produce the food humans eat and the fiber that humans used for clothing and shelter. Almost all cultures have their roots in our biological diversity in some way or form. At such a time, markets mobilize automatically to address this by looking for ways to bring down costs. Instead of regulation to change people’s habits, markets would automatically reflect these true costs; consumers can then make better informed choices about what to consume, e.g. The park where things were left alone has naturally regenerated; the large elephant populations eventually reduced in number as they undermined their own resource base. It is hard to know, but there is a lot of waste in the existing system. Private and public decisions affecting biodiversity rarely consider benefits beyond the immediate geographical area…. While there are disagreements and differences on how this works, it suggests that ecological balance and biodiversity are crucial for all of earth, not just humans. Biodiversity in all of its forms—ecological, species, and genetic—is important for numerous reasons. Biodiversity is important for maintaining an important balance of the ecosystem. It is no secret that humans have an enormous impact on species and ecosystem diversity, yet, throughout our existence, biodiversity has faithfully provided us with enormous economic, medical and social benefits as well as many other natural services. A report from Nature magazine also explains that genetic diversity helps to prevent the chances of extinction in the wild (and claims to have shown proof of this). This will take a little while to explain so please bear with me. The diversity of plants in the many ecosystems is the source for medicines that humans use to treat disease. represents ‘natural’ component of the market. Even these services often bypass markets where carried out as part of community management of shared resources. An ecosystem can only truly thrive if all life forms in it are thriving. https://greentumble.com/why-is-it-important-to-conserve-biodiversity The price signal also implies the poorest often pay the heaviest costs. Martin Khor: Historical Responsibility for Climate Change Emission Reduction, Global temperature anomalies, 1880 - 2014, http://www.wwf.org.uk/core/wildlife/fs_0000000029.asp, http://web.archive.org/web/20070103012619/http://www.wwf.org.uk/core/wildlife/fs_0000000029.asp, http://www.ipsnews.net/news.asp?idnews=49300, https://www.globalissues.org/news/2009/11/17/3539, http://www.panos.org.uk/download.php?id=84, US$ 70 bn. It is a type of cooperation based on mutual survival and is often what a balanced ecosystem refers to. Without this, elephants were stripping vegetation bare, affecting other animals, too. It includes the concepts of species diversity, habitat diversity and genetic diversity. As such, it is essential that we actively choose to minimize the negative impacts that our actio… The link and dependency between plants, bees, and human agriculture is so crucial, the two scientists writing up years of research into the problem summarized with this warning: Humankind needs to act quickly to ensure that the ancient pact between flowers and pollinators stays intact, to safeguard our food supply and to protect our environment for generations to come. Anita Roddick: Corporate Social Responsibility? By contrast, waiting 10 more years could reduce the net benefit of halving deforestation by US$ 500 billion. Forests and wetland ecosystems provide crucial buffers to extreme storms and flooding related to climate change. We also need to protect our water resources, protecting soil & maintaining eco-balance. Who Cares? Think of some of the effects this could have: How much would such accounting save? Write. Biodiversity is categorized into species diversity, genetic diversity and ecosystem diversity. However, it has long been argued that prices don’t truly reflect the full cost of things, so either the signal is incorrect, or comes too late. Ecosystem is more diverse when it contains varied landscapes, creating more space for shelter and escapes which allows the rapid growth of plants as … Why 'Crocodile Dundee' star, 81, came out of retirement. Diversity In an aquatic environment helps in … Added an update on declining numbers of large carnivores, Added a couple of videos about measuring environmental costs to society, Added notes about how environmental needs to be measured by our economic systems, Short notes and illustrations added on further reasons for biodiversity importance, Short examples added of how ecosystems rely on various species’ interactions and dependencies.
