why is ecosystem diversity important

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. It noted how a few decades ago, some fishermen campaigned for killing whales because they were threatening the fish supply and thus jobs. STUDY. One of the main reasons we should continue to focus on preserving biodiversity is that it helps to boost ecosystem productivity. This systematic under-valuation of ecosystem services and failure to capture the values is one of the main causes underlying today’s biodiversity crisis. Why Is Biodiversity Important? Biodiversity is important for maintaining an important balance of the ecosystem. Since each species has a role to play, a diverse ecosystem allows them to interact and reach symbiosis. Biodiversity is categorized into species diversity, genetic diversity and ecosystem diversity. What is biodiversity? The cost of replacing these (if possible) would be extremely expensive. 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.. Match. And as we start destroying, reducing and isolating habitats, the chances for interaction from species with a large gene pool decreases. The earth itself sets an example of ecosystem diversity as it contains forests, oceans, deserts and wetlands. A healthy ecosystem stems from rich biodiversity. Biodiversity in all of its forms—ecological, species, and genetic—is important for numerous reasons. 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). Terms in this set (18) Biodiversity. 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. 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). More examples are discussed on this site’s section on consumption and consumerism). 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. Ecosystem diversity is a type of biodiversity. Ecosystem Productivity. Climate Change and Global Warming Introduction. Many people may support environmental causes to help preserve the beauty of Nature. 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. Economists talk of the price signal that is fundamental to capitalism; the ability for prices to indicate when a resource is becoming scarcer. 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. Why is Biodiversity Important? (2006) from public companies alone, Many products derived from genetic resources (enzymes, microorganisms), Personal care, Botanical and food & Beverage industries. PLAY. Generally, when a variety is extinct from it or there is a decrease in its population, this indicates that these species were not … 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. To print all information (e.g. The biodiversity of an ecosystem is important because it stabilises the whole system where life is present. Social, Political, Economic and Environmental Issues That Affect Us All. Image Source: Twitter. On a large scale for example plants have diversity to prevent them from being wiped out by a parasitic attack or something. 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 … 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. 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. Who Cares? 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.”. 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. Being against prevailing thought, they would not agree. It is a type of cooperation based on mutual survival and is often what a balanced ecosystem refers to. Spell. 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. And so, while we dominate this planet, we still need to preserve the diversity in wildlife. 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. Podcast: Why Diversity is Important in a Startup Ecosystem? An ecosystem can only truly thrive if all life forms in it are thriving. 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…. Our eagle example also demonstrates another aspect of diversity. 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. 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. At such a time, markets mobilize automatically to address this by looking for ways to bring down costs. Why do we need to protect biodiversity? 15 Jan. 2021. 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. Recreation—many recreational pursuits rely on our unique biodiversity, such as birdwatching, hiking, camping and fishing. The fact that within a forest, pond or sea there are countless different animals, plants, fish, birds and so on all living together. For example, A larger number of plant species means a greater variety of crops; Greater species … Values that are not overtly part of a financial equation are too often ignored. Biodiversity is important because it boosts ecosystem productivity where each species all have an important role to play. . Private and public decisions affecting biodiversity rarely consider benefits beyond the immediate geographical area…. 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. 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. Think of some of the effects this could have: How much would such accounting save? costs that have to be borne by society from ignored factors, or social costs). 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. Biodiversity is important because it clears out our water, changes out climate, and provides us with food. Web. https://greentumble.com/why-is-it-important-to-conserve-biodiversity 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. Biodiversity also absorbs pollution, promotes tourism, supports education and research and maintains the ecosystem. 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. Migratory species including birds, fish, mammals, and insects all depends upon different ecosystems during their movements. 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.
