why is ecosystem diversity important

An estimated 40% of world trade is based on biological products or processes. Without this, elephants were stripping vegetation bare, affecting other animals, too. The fact that within a forest, pond or sea there are countless different animals, plants, fish, birds and so on all living together. Terms of Use, Privacy Policy, Cookie Policy, and Copyrights. Appropriate conservation and sustainable development strategies attempt to recognize this as being integral to any approach to preserving biodiversity. The earthworm is like a natural tractor, fertilizer factory and dam, combined! We also need to protect our water resources, protecting soil & maintaining eco-balance. Who Cares?.” Global Issues. This systematic under-valuation of ecosystem services and failure to capture the values is one of the main causes underlying today’s biodiversity crisis. PLAY. There are several important reasons for us to gain an understanding of the dynamic nature of biological diversity, particularly in terms of maintaining ecological balance. It is the variation in the ecosystems found in a region or the variation in ecosystems over the whole planet. For example, if energy costs go up, businesses will look for a way to minimize such costs for themselves, and it is in such a time that alternatives come about and/or existing resources last longer because they are used more efficiently. A few years later, they found the park with the culled population had remained in poor condition. Efficiently producing unhealthy food — and the unhealthy consumer culture to go with it — may profit the food industry and a private health sector that has to deal with it, all of which require more use of resources. For more information on this question, visit some of the following links. Not only does diversity ensure species reproduction it also cultivates competion. Ecosystems produce the food humans eat and the fiber that humans used for clothing and shelter. This is a clear case of inter-related issues: the health of the environment is strongly tried to our economic choices (i.e. For example, a documentary aired on the BBC (I unfortunately forget the name and date, but in the 1990s) described two national parks in Africa where elephant populations had grown quite large within those artificial boundaries. 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? costs that have to be borne by society from ignored factors, or social costs). The variety of life on Earth, its biological diversity is commonly referred to as biodiversity. Anita Roddick: Corporate Social Responsibility? 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. Why is diversity important in an ecosystem? how we use resources), but addressing core short-comings in our economic systems is a crucial political challenge. Importance of Ecosystem: It provides habitat to wild plants and animals. Bees are more important than poultry in terms of human nutrition. Climate Change and Global Warming Introduction. An ecosystem will have a higher productivity rate and more robust ecological processes when more different life forms can thrive and survive. diversity is not only important but required. This is mainly explained by the fact that many ecosystem services are ‘public goods’ or ‘common goods’: they are often open access in character and non-rival in their consumption. Alternatively, copy/paste the following MLA citation format for this page: Shah, Anup. In the end they agreed to let one park have its elephants culled, while the other would be left alone. To print all information (e.g. 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. Forests and wetland ecosystems provide crucial buffers to extreme storms and flooding related to climate change. It promotes various food chains and food webs. Ecosystem diversity is a type of biodiversity. 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. Healthy ecosystems can better withstand and recover from a variety of disasters. 15 Jan. 2021. Ecosystem Productivity. This is equivalent to 7% of their combined revenues and up to a third of their combined profits. It is hard to know, but there is a lot of waste in the existing system. 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. Without diversity in the ecosystem species would be suscepitable biological hazards. 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…. The diversity creates an interdependence between organisms in the ecosystem. Other wildlife grew in numbers and the ecosystem was generally back in balance. Write. Diversity is necessary in an ecosystem to help drive the gene pool and further evolution of species. The price signal also implies the poorest often pay the heaviest costs. A healthy biodiversity provides many natural services that are beneficial for everyone. So much so that economic measures such as GDP often ignores environmental costs. The three types of biodiversity (species, genetic, and ecosystem) help keep a healthy and sustainable ecosystem and environment for a long period of time. Each ecosystem provide different habitats that can essential for a species's life cycle. The fact that in the world there are deserts, seas, ponds and forests, all of them with animals living in them. The amount of biological or living diversity per unit area. 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. For example, as mentioned in the previous link, if water used by the meat industry in the United States were not subsidized by taxpayers, common hamburger meat would cost $35 a pound. 2. Spell. Bees provide enormous benefits for humankind as another example. This can be done by recycling & storage of nutrients, controlling pollution, & stabilizing climate. Since each species has a role to play, a diverse ecosystem allows them to interact and reach symbiosis. While there might be survival of the fittest within a given species, each species depends on the services provided by other species to ensure survival. In addition, they cited another study that estimated that 3,000 listed companies around the world were responsible for over $2 trillion in environmental externalities (i.e. 1. 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. The earth itself sets an example of ecosystem diversity as it contains forests, oceans, deserts and wetlands. For example, A larger number of plant species means a greater variety of crops; Greater species … Our continued inefficient pumping of greenhouse gases into the environment without factoring the enormous cost as the climate already begins to change is perhaps an example where price signals may come too late, or at a time when there is already significant impact to many people. 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.”. 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. Recreation—many recreational pursuits rely on our unique biodiversity, such as birdwatching, hiking, camping and fishing. Why do we need to protect biodiversity? Some products derived from genetic resources. As such, it is essential that we actively choose to minimize the negative impacts that our actio… 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. 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). represents ‘natural’ component of the market. Ecosystem diversity is very important because all life forms on earth depend on each other. To prevent the well known and well documented problems of genetic defects caused by in-breeding, species need a variety of genes to ensure successful survival. The fact that within a forest, pond or sea there are countless different animals, plants, … Existing price signals only reflect - at best - the share of total value that relates to provisioning services like food, fuel or water and their prices may be distorted. Human intervention to perform the same services would be more costly. 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). The values of other ecosystem services are generally not reflected in markets apart from a few exceptions (such as tourism). For example, our ecosystem services such as pollution breakdown and absorption and protection of water resources. 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. Think of some of the effects this could have: How much would such accounting save? The cost of replacing these (if possible) would be extremely expensive. Diversity In an aquatic environment helps in … 21-year-old arrested in Nashville nurse slaying: Police. In addition, the richer the diversity of life, the greater the opportunity for medical discoveries, economic development, and adaptive responses to such new challenges as climate change. 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). Land that is used to produce unhealthy or marginally nutritious items (e.g. The massive reduction in the local whale population meant killer whales in the region (usually preying on younger whales) moved to other animals such as seals; As seal numbers declined, the killer whales targeted otters; As otter numbers were decimated, the urchins and other targets of otters flourished; These decimated the kelp forests where many fish larvae grew in relative protection; The exposed fish larvae were easy pickings for a variety of sea life; The above would be a good return on the initial investment. The Economics of Ecosystems and Biodiversity (TEEB) is an organization — backed by the UN and various European governments — attempting to compile, build and make a compelling economics case for the conservation of ecosystems and biodiversity. Biological diversity, or biodiversity, is the scientific term for the variety of life on Earth. A scientist pleaded with park management not to cull and let nature take its course. Why is Biodiversity Important? A healthy ecosystem stems from rich biodiversity. With between 3 and 30 million species on earth, here are the reasons why they are important. We need ants to survive, but they don't need us at all. 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). Image Source: Twitter. And as we start destroying, reducing and isolating habitats, the chances for interaction from species with a large gene pool decreases. It was noted earlier that ecosystems provide many services to us, for free. 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. At least 40 per cent of the world’s economy and 80 per cent of the needs of the poor are derived from biological resources. Even these services often bypass markets where carried out as part of community management of shared resources. 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. 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. Resources that could be available more indefinitely, become finite because of our inability or unwillingness to change. 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). from climate regulation) are frequently ignored. (2006) from public companies alone, Many products derived from genetic resources (enzymes, microorganisms), Personal care, Botanical and food & Beverage industries. Biodiversity in all of its forms—ecological, species, and genetic—is important for numerous reasons. In addition, their benefits are felt differently by people in different places and over different timescales. Web. Diversity in the ecosystem is significant to human existence for a variety of reasons. As a simple example, the loss of a large carnivore may mean in the short term the herbivores they prey on may increase in numbers but this can also result in a deterioration of the environment as the herbivores can graze more, largely unchecked. 19 Jan. 2014. These words sum up why biodiversity is so important. Why is the Ecosystem so Important? The reason it can be explained with a disease is because the habitat of the vector involved fragmented low diversity areas. Biodiversity is important for maintaining an important balance of the ecosystem. Involved in the recycling of nutrients between biotic and abiotic components. Test. Why is BIODIVERSITY important? But honeybees, the primary species that fertilizes food-producing plants, have suffered dramatic declines in recent years, mostly from afflictions introduced by humans. As described by Google, it is defined as, "the variety of life in the world or in a particular habitat or ecosystem." This also has a negative impact on the environment, perhaps partly formed by outdated-views that predators are harmful for other wildlife. In a recent report, The Economics of Ecosystems and Biodiversity for National and International Policy Makers 2009, TEEB provided the following example of sectors dependent on genetic resources: In addition, it is estimated that implementing REDD (Reducing Emissions from Deforestation and Forest Degradation) could help, From a cost perspective (p.18), it is estimated that. Generally, when a variety is extinct from it or there is a decrease in its population, this indicates that these species were not … Running out of resources should therefore be averted. This then has an impact on various local social, political and economic issues. The diversity of plants in the many ecosystems is the source for medicines that humans use to treat disease. Biodiversity is important because it boosts ecosystem productivity where each species all have an important role to play. 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. Gravity. Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. It controls essential ecological processes and promotes lives. Flashcards. 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. Industrial-farming techniques would deprive these diverse species of food sources and instead assault them with chemicals, destroying the rich biodiversity in the soil and with it the basis for the renewal of the soil fertility. Who Cares?, Global Issues, Updated: January 19, 2014. 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? STUDY. kodakoda2223. 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). Although some dislike the thought of trying to put an economic value on biodiversity (some things are just priceless), there have been attempts to do so in order for people to understand the magnitude of the issue: how important the environment is to humanity and what costs and benefits there can be in doing (or not doing) something. 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. “Why Is Biodiversity Important? The economic benefits of protecting the environment are well-understood, even if seemingly rarely practiced: Numerous studies also show that investments in protected areas generate a cost-benefit ratio of one to 25 and even one to 100 in some cases, [Pavan Sukhdev, from TEEB] said. Ecosystem diversity. A reduction in meat production could protect forests or help reduce clearance of forests for cattle ranches, which would have a knock-on benefit for climate change concerns. Despite these free benefits, it has long been recognized that we tend to ignore or underestimate the value of those services. 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. The G8 nations, together with 5 major emerging economies — China, India, South Africa, Brazil, Mexico — use almost three-quarters of the Earth’s biocapacity. 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. Discover the Importance of India. 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. by reducing their meat consumption or demand more ecologically sustainable alternatives at reasonable cost. Appreciating diversity is important as this is what forms the societies that we live in. Tense postgame handshake between college coaches Biodiversity plays significant role in soil formation and its conservation. Nature can often be surprisingly resilient, often without the need for human interventions. On a large scale for example plants have diversity to prevent them from being wiped out by a parasitic attack or something. Ecosystem diversity. The usual way to deal with this was to cull the population to try and keep the ecosystem in balance. 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. 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. Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. Having a rich variety of ecosystems, what biologists call ecosystem diversity, constitutes another important level of biodiversity. For many decades, various environmentalists, biologists and other scientists, have viewed the entire earth as a massive living organism or system due to the interdependent nature of all species within it. As the study notes, human actions cannot fully replace the role of large carnivores because these large carnivores are an intrinsic part of an ecosystem’s biodiversity. Without this, the chances of extinction increases. So, an example of ecosystem diversity might be: The fact that in the world there are deserts, seas, ponds and forests, all of them with animals living in them. . Spiders, centipedes and insects grind organic matter from the surface soil and leave behind enriched droppings. Naturally, those who benefit from the current system may be hostile to such changes, especially if it may mean they might lose out. 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. 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. Values that are not overtly part of a financial equation are too often ignored. January 29, 2020 Valentina Primo In the last episode of the #SWBSummit series, we bring the panel where Egyptian power lady Yara El Braidy sits with two Egyptian entrepreneurs experiencing diverse ecosystems in Jordan … 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. Teach a man to fish; and you have fed him for a lifetime.” — Old Chinese Saying. The importance of ecosystem diversity can be explained by the fact that a lack of it led to a outbreak of Lyme disease. It noted how a few decades ago, some fishermen campaigned for killing whales because they were threatening the fish supply and thus jobs. Where possible, alternative links are provided to backups or reposted versions here. Created by. “Give a man a fish; you have fed him for today. Who Cares? The biodiversity of an ecosystem is important because it stabilises the whole system where life is present. The Gulf Coast of Florida is another unique ecosystem with different characteristics. Explanation: It has perhaps taken about a decade or so — and a severe enough global financial crisis that has hit the heart of this way of thinking — to change this mentality (in which time, more greenhouse gases have been emitted — inefficiently). Thus preserving the structure of biological communities rather than increasing the number of species are very important for maintaining ecosystem services. 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. It therefore makes economic and development sense to move towards sustainability. This will take a little while to explain so please bear with me. Ecosystem diversity boosts the availability of oxygen via the process of photosynthesis amongst plant organisms domiciled in the habitat. 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). As German bee expert Professor Joergen Tautz from Wurzburg University adds: Bees are vital to bio diversity. Some cultures have recognized this kind of inter-relationship for a very long time. 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.. Humans rely on ecosystems for many functions. It is a type of cooperation based on mutual survival and is often what a balanced ecosystem refers to. However, for similar information, you could look at, What the global economy would look like with nature on the balance sheet, The hidden environmental and social costs from corporations, Renewable Energy Transition Key to Addressing Climate Change Challenge, For Heavily Indebted Small Islands, Resilience-Building is the Best Antidote, Facing their Failure to meet 2020 Biodiversity Targets, World Leaders Pledge Action & Funds, https://www.globalissues.org/article/170/why-is-biodiversity-important-who-cares, https://www.globalissues.org/print/article/170, A healthy biodiversity offers many natural services, Soil, bacteria, plants; the Nitrogen Cycle, Large carnivores essential for healthy ecosystems, Biodiversity providing lessons for scientists in engineering, More important than human use or biological interest, Putting an economic value on biodiversity, A larger number of plant species means a greater variety of crops, Causes, consequences and ethics of biodiversity, Bees provide enormous benefits for humankind, Solving the Mystery of the Vanishing Bees, Three quarters of the world’s big carnivores are in decline, human actions cannot fully replace the role of large carnivores, some spiders can produce their silk with a higher tensile strength than many alloys of steel, The Economics of Ecosystems and Biodiversity (TEEB), The Economics of Ecosystems and Biodiversity for National and International Policy Makers 2009, Environment: Save At Least Half the Planet, or Lose It All. Add another link to more information about importance of biodiversity. For example, commercially over-fishing a region may mean fish from that area becomes harder to catch and more expensive, possibly allowing that ecosystem time to recover (though that is not guaranteed, either). 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. They provide aerage, drainage and maintain soil structure. Biodiversity is important because it clears out our water, changes out climate, and provides us with food. It includes the concepts of species diversity, habitat diversity and genetic diversity. Private and public decisions affecting biodiversity rarely consider benefits beyond the immediate geographical area…. Migratory species including birds, fish, mammals, and insects all depends upon different ecosystems during their movements. 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. Being against prevailing thought, they would not agree. Economists talk of the price signal that is fundamental to capitalism; the ability for prices to indicate when a resource is becoming scarcer. What is biodiversity? 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. And so, while we dominate this planet, we still need to preserve the diversity in wildlife. Many people may support environmental causes to help preserve the beauty of Nature. 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. By contrast, waiting 10 more years could reduce the net benefit of halving deforestation by US$ 500 billion. Social, Political, Economic and Environmental Issues That Affect Us All. Biodiversity is very important to the well-being of our planet and here’s why. Almost all cultures have their roots in our biological diversity in some way or form. The maintenance of genetic diversity is important services that ecosystem provide from biodiversity. Podcast: Why Diversity is Important in a Startup Ecosystem? Rest is unchanged, for now, since January 1, 2001. Unfortunately the original link to the Nature.com article no longer works, since their site redesign, and I had not noted the publication details.
