It has played a major role in shaping the diversity of nature at the genetic, species and ecological levels. 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. Without a name and description, a species cannot be studied in depth and in a coordinated way by multiple scientists. But how exactly is biodiversity so important to humanity? Trees and plants also store carbon in their tissue, making it even more necessary to protect them. Loss of these species would make growing crops requiring pollination impossible, increasing dependence on other crops. The world’s growing human population faces significant challenges in the increasing costs and other difficulties associated with producing food. Loss of wild species related to a crop will mean the loss of potential in crop improvement. One of the oldest observed patterns in ecology is that biodiversity typically increases as latitude declines. However, biologists are using different measures of biodiversity, including genetic diversity, to help focus efforts to preserve the biologically and technologically important elements of biodiversity. Biodiversity is a broad term for biological variety, and it can be measured at a number of organizational levels. Resistance to disease is a chief benefit to maintaining crop biodiversity and lack of diversity in contemporary crop species carries similar risks. projects expand deeper into tropical forests, humans are increasing their exposure to wild animals — and the diseases they may carry. is no likely ecological impact. The potato demonstrates a well-known example of the risks of low crop diversity: during the tragic Irish potato famine (1845–1852 AD), the single potato variety grown in Ireland became susceptible to a potato blight—wiping out the crop. including birds, Nile crocodiles and hippos and a source of food and income for about 300,000 people. Table 1. They also lead to collateral damage by killing non-pest species as well as beneficial insects like honeybees, and risking the health of agricultural workers and consumers. Naming and counting species may seem an unimportant pursuit given the other needs of humanity, but it is not simply an accounting. The current rate of extinction is … Fishery extinctions rarely lead to complete extinction of the harvested species, but rather to a radical restructuring of the marine ecosystem in which a dominant species is so over-harvested that it becomes a minor player, ecologically. Moreover, these pesticides may migrate from the fields where they are applied and do damage to other ecosystems like streams, lakes, and even the ocean. That subsequent research will produce the discoveries that make the species valuable to humans and to our ecosystems. Importance of Biodiversity. A common meaning of biodiversity is simply the number of species in a location or on Earth; for example, the American Ornithologists’ Union lists 2078 species of birds in North and Central America. They are now all but gone, replaced by crop fields, pasture lands, and suburban sprawl. 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. 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. January 16, 2020. Biodiversity is the amount of variety of life on Earth. The biodiversity found on Earth today is the result of approximately 3.5 billion years of evolution. And we’d lose all the valuable oxygen, homes for birds and animals, and wood for buildings and furniture. Loss of biodiversity may have reverberating consequences on ecosystems because of the complex interrelations among species. For example, the COVID-19 pandemic can likely be sourced to a wild animal and fish market in Wuhan, China. The potatoes grown in that region belong to seven species and the number of varieties likely is in the thousands. Species are frequently integral to religious, cultural and national identities. Protecting the nature we all rely on for food, fresh water and livelihoods. For example, potatoes were domesticated beginning around 7,000 years ago in the central Andes of Peru and Bolivia. There are three main fields of study under the heading of biogeography: ecological biogeography, historical biogeography (called paleobiogeography), and conservation biogeography. The destruction of forest ecosystems is responsible for 11 percent of Genetic diversity is one alternate concept of biodiversity. It normally appears in one volume per year with typically 200–300 pages. Many medications are derived from natural chemicals made by a diverse group of organisms. Protecting biodiversity plays a crucial part in achieving these emissions reductions. Maintaining the genetic diversity of wild species related to domesticated species ensures our continued supply of food. Protecting biodiversity plays a crucial part in achieving these emissions reductions. Antibiotics, which are responsible for extraordinary improvements in health and lifespans in developed countries, are compounds largely derived from fungi and bacteria. Endemic species are found in only one location. The stability of tropical ecosystems might promote speciation. In addition, the loss of an inexpensive protein source to populations that cannot afford to replace it will increase the cost of living and limit societies in other ways. 2018 Jan;2(1):57-64. doi: 10.1038/s41559-017-0402-5. It is not yet clear why biodiversity increases closer to the equator, but hypotheses include the greater age of the ecosystems in the tropics versus temperate regions, which were largely devoid of life or drastically impoverished during the last ice age. The loss of a particular individual species may seem unimportant to some, especially if it is not a charismatic species like the Bengal tiger or the bottlenose dolphin. The diversity of species and genes in ecological communities affects the functioning of these communities. But since 1990, production from global fisheries has declined. Conditions within the vault are maintained at ideal temperature and humidity for seed survival, but the deep underground location of the vault in the arctic means that failure of the vault’s systems will not compromise the climatic conditions inside the vault. Ecosystems weakened by the loss of biodiversity are Seed companies, which are the source of most crop varieties in developed countries, must continually breed new varieties to keep up with evolving pest organisms. In general, the fish taken from fisheries have shifted to smaller species and the larger species are overfished. As the global wildlife trade continues and development Nature-related tourism is also a significant income generator for many people as well. Most cultures, at least at some time, have recognized the importance of … Biodiversity loss refers to the reduction of biodiversity due to displacement or extinction of species. and other products made from natural materials for their own use and as sources of income. These biodiversity variables simplify the selection of areas for biodiversity importance. We're proud to be recognized as a financially accountable and transparent organization. Biodiversity and Ecology Biodiversity is the divergency of species present in different eco-systems. The people in this region traditionally lived in relatively isolated settlements separated by mountains. worth US$ 2 to 6 trillion by 2050. carriers like mosquitoes to extend their geographic ranges and infect new populations of humans. A challenge in implementing biodiversity conservation is in reconciling criteria for identifying significant areas and representative networks for biodiversity protection. Lake Victoria contained almost 500 species of cichlids (just one family of fishes that are present in the lake) before the introduction of an exotic species in the 1980s and 1990s caused a mass extinction. The geographic coverage ranges from the floodplains of the Brazilian Amazon to the agricultural landscapes of Southeast Asia, and the coral … More sophisticated measures of diversity take into account the relative abundances of species. The lake is under heavy pressure because of overfishing, cyclical drought, changing rainfall patterns and the diversion of water by upstream developments, Between 1970 and 2011, almost 20 percent of the Amazon rainforest was lost. formally used as national symbols in 142 countries. That number has probably decreased to about 10 percent as natural plant ingredients are replaced by synthetic versions of the plant compounds. Modified from the original by Matthew R. Fisher. The diversity of species provides humans with a wide range of economic benefits: Wild plants and animals maintain a valuable pool of genetic variation.This is important because domestic species are genetically uniform. Replacing the work of these organisms in forming arable soil is not practically possible. Potatoes are only one example of agricultural diversity. It includes organisms from Earth’s vastly different ecosystems, including deserts, rainforests, coral reefs, grasslands, tundra, and polar ice caps. Ecologists believe that the bulk of the work in removing pests is actually done by predators and parasites of those pests, but the impact has not been well studied. Biodiversity is very important to the well-being of our planet and here’s why. Honeybee populations in North America have been suffering large losses caused by a syndrome known as colony collapse disorder, a new phenomenon with an unclear cause. Examples include the ornamental plants, birds and animals that people use to enrich their lives, the variety of foods they use to enrich their diet, the mix of biofuels or biofibres used to support productive activities. That biodiversity creates the conditions under which crops are able to grow through what are known as ecosystem services—valuable conditions or processes that are carried out by an ecosystem. Prairies once spanned central North America from the boreal forest in northern Canada down into Mexico. This is the reason why beavers are known as a “keystone species”, a term used to describe a species that greatly affects its surroundings, to the point where other species are highly dependent on … They are grown in soil. 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. Share this with Facebook Share this with Twitter Share this with LinkedIn Share this with Email Print this. There is considerable research into the psychologically regenerative benefits of natural landscapes that suggest the hypothesis may hold some truth. The pathway diagram below shows the potential impact of SuDS on biodiversity. These booms in biodiversity are all thanks to beavers. Another possible explanation is the greater energy the tropics receive from the sun. Biodiversity enhancement details . Another five drugs are undergoing clinical trials and at least six drugs are being used in other countries. This is one measure of the bird biodiversity on the continent. Unfortunately, more than one-third of those species are threatened, but the bald Meanwhile The Economics of Ecosystems and Biodiversity (TEEB) initiative estimates that global sustainable business opportunities from investing in natural resources could be Our biodiversity is very important to the well-being of our planet. Finally, humans compete for their food with crop pests, most of which are insects. Agriculture began after early hunter-gatherer societies first settled in one place and heavily modified their immediate environment. and these changes are leading to a loss of biodiversity, declines in fisheries’ yields and a reduced ability to support humans. All developments, particularly where there is a potential impact to ecology, are required to conserve, restore and enhance the biodiversity assets of Herefordshire. The greater age provides more time for speciation, the evolutionary process of creating new species. The work of biogeographers is critical to understanding our physical environment, how the environment affects species, and how changes in environment impact the distribution of a species. This post was originally published on the Zayed Future Energy Prize blog and is reprinted with permission. Importance of Biodiversity . Also Read: Flagship Species. Therefore, it is very important to have a good knowledge of biodiversity for a sustainable livelihood. At least 40 percent of the world’s economy and 80 percent of the needs of the poor are derived from biological resources. By Jim Shelton. We value biodiversity for many reasons, some utilitarian, some intrinsic. Many of the species survive, but the hugely productive ecosystem that was responsible for creating our most productive agricultural soils is now gone. One example of this is Kenya’s Lake Turkana — the world’s largest desert lake, a habitat for a variety of wildlife ECOLOGICAL AND ECONOMICAL IMPORTANCE OF BIODIVERSITY Biodiversity is considered a cornerstone to the health of the environment. The loss of the crop led to famine, death, and mass emigration. The other great apes, orangutans, chimpanzees, bonobos, and gorillas have all been observed self-medicating with plants. The chief proponent of this idea is famed entomologist E. O. Wilson. Lake Huron contains about 79 species of fish, all of which are found in many other lakes in North America. Since the beginning of human agriculture more than 10,000 years ago, human groups have been breeding and selecting crop varieties. Describing species is a complex process by which biologists determine an organism’s unique characteristics and whether or not that organism belongs to any other described species. Estimates of numbers of prokaryotic species are largely guesses, but biologists agree that science has only just begun to catalog their diversity. Other key ecosystem services related to food production are plant pollination and crop pest control. The natural disaster prevention mechanisms in most ecosystems and other free services we all get from the surrounding environment are not easily replaceable or replicable, so maintaining biodiversity is important. Our ecosystems provide us with food, medicine, clean air and water, recreation, and spiritual and aesthetical inspiration. The loss of an ecosystem means the loss of the interactions between species and the loss of biological productivity that an ecosystem is able to create. Creative Commons Attribution 4.0 International License. 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 wild animals. Other toxins under investigation come from mammals, snakes, lizards, various amphibians, fish, snails, octopuses, and scorpions. These kinds of processes are called ecosystem services. all global greenhouse gas emissions caused by humans, so conserving forests would stop the release of these gases into the atmosphere. “For a relatively small investment, high-biodiversity forests and other ecosystems can be conserved and restored as a powerful means to rein in climate change while also helping communities cope with associated storms, flooding and other impacts,” Endemic species with highly restricted distributions, like the Barton Springs salamander, are particularly vulnerable to extinction. It has contributed in several ways to the development of human culture and, in turn, human communities. Genetic diversity is the raw material for evolutionary adaptation in a species and is represented by the variety of genes present within a population. By … For example, the richness of diversity allows medicines and foods to be naturally available. For about one billion people, aquatic resources provide the main source of animal protein. Some ecosystems, such as mangroves, are particularly good at storing carbon and keeping it out of the atmosphere — where it contributes to climate change. Conservation researchers Paul R. and Anne Ehrlich posited in the 1980s that species are to ecosystems what rivets are to a plane’s As a consequence, their soils are now being depleted unless they are maintained artificially at great expense. Get the latest updates on our work delivered to your inbox. The work of biogeographers is critical to understanding our physical environment, how the environment affects species, and how changes in environment impact the distribution of a species. This system has flaws because over time seed varieties are lost through accidents and there is no way to replace them. Around 75 percent of global food crops rely on animals and insects such as bees to pollinate them, but many of these pollinator populations are in decline — which could put more than US$ 235 billion of agricultural products at risk. All major religions include elements of nature and 231 species are Much of this loss is occurring in tropical rainforests like the one pictured in Figure 1, which are very high in biodiversity but are being cleared for timber and agriculture. Other pollinators include a diverse array of other bee species and various insects and birds. It is the number of different species of plants, animals, and microorganisms. Historical biogeography, as the name implies, studies the past distribution of species. In addition to humans losing the food source, these alterations affect many other species in ways that are difficult or impossible to predict. It is estimated that, at one time, 25 percent of modern drugs contained at least one plant extract. Words by 3p Contributor. These organisms also maintain soil texture that affects water and oxygen dynamics in the soil that are necessary for plant growth. Many medications were once derived from plant extracts but are now synthesized. Biologists recognize that human populations are embedded in ecosystems and are dependent on them, just as is every other species on the planet. It may not be self-evident, so here are five reasons. In addition to growing crops and raising food animals, humans obtain food resources from wild populations, primarily wild fish populations. To qualify as a Road Verge of Ecological Importance (RVEI), the verge must support either a notable species and/or a species rich semi-natural habitat. Humanity must stop the pace of wildlife extinctions — or face extinction itself, according to a growing body of research. The decline in soil productivity occurs because the interactions in the original ecosystem have been lost. Regardless of the mechanisms, it is certainly true that biodiversity is greatest in the tropics. The collapse of fisheries has dramatic and long-lasting effects on local human populations that work in the fishery. Why is biodiversity necessary for the stability of the planet? These ecological effects of biodiversity in turn are affected by both climate change through enhanced greenhouse gases, aerosols and loss of land cover, and biological diversity, causing a rapid loss of biodiversity and extinctions of species and local populations. Biologists have also identified alternate measures of biodiversity, some of which are important in planning how to preserve biodiversity. In a landmark study published in 2017, a group of researchers led by Bronson Griscom, who researches natural climate solutions at Conservation International, Lake Victoria is a tropical lake, while Lake Huron is a temperate lake. The ecological importance of intraspecific variation Nat Ecol Evol. In 2008, the Svalbard Global seed Vault, located on Spitsbergen island, Norway, (Figure) began storing seeds from around the world as a backup system to the regional seed banks. Biodiversity & Ecology publishes research papers as well as forum papers, reviews and reports on biodiversity, evolution, and ecology. Seventy percent of emerging viral diseases have spread from animals to humans. Each variety has been bred to thrive at particular elevations and soil and climate conditions. wing. A common measure of this variety, called species richness, is the count of species in an area. There are various initiatives to catalog described species in accessible and more organized ways, and the internet is facilitating that effort. There are numerous reasons deeming biodiversity significant. Biodiversity, also called biological diversity, the variety of life found in a place on Earth or, often, the total variety of life on Earth. The loss of biodiversity will include many species we know today. These wild forms are often the source of new gene variants that can be bred with existing varieties to create varieties with new attributes. Losing one might not be a disaster, but each loss adds to the likelihood of a serious problem. Biodiversity is the variety of species used in both the production and consumption of goods and services. We in turn depend on the environment for our own health and existence. There are a number of SuDS components that can make a significant contribution to the biodiversity (ecological) value of an area (eg green roofs, ponds, swales, wetlands, trees). Given that Earth is losing species at an accelerating pace, science knows little about what is being lost. Approximately 15 to 20 RVEIs are surveyed each year by the Hampshire Biodiversity Information Centre (HBIC) as part of an annual survey programme to assess their value for biodiversity. eagle and American bison are examples of conservation successes because of their role as national symbols. Ecological and economical importance of biodiversity 1. Ecosystems such as parks and other protected areas also provide recreation and a knowledge resource for visitors, and biodiversity is a frequent However, many extinctions will affect species that biologist have not yet discovered.
