Biodiversity • Photo: Public Library of Science (PLoS) Related Links The Convention on Biological Diversity website contains the actual convention documents, which were signed by 150 government leaders at the 1992 Rio Earth Summit and exist to promote sustainable development. The site also contains information resources related to the topic.
Green Facts is an independent, nonprofit organization with a multistakeholder governance and a nonadvocacy policy. The organization aims to bring complex scientific consensus reports on health and the environment to the reach of nonspecialists.
Its site contains a wealth of detailed information related to biodiversity. The National Agricultural Library is one of four national libraries of the United States. It houses one of the world’s largest and most accessible agricultural information collections. Use the search engine to find publications and news releases containing the most recent information on biodiversity, including E.O. Wilson’s book on the subject. Biodiversity is the sum of all the different species of animals, plants, fungi and microbial organisms living on Earth and the variety of habitats in which they live.
Economic Value Of Biodiversity
Scientists estimate that more than 10 million different species inhabit Earth. Biodiversity underlies everything from food production to medical research.
Humans use at least 40,000 species of plants and animals on a daily basis. Many people around the world still depend on wild species for some or all of their food, shelter and clothing. All our domesticated plants and animals came from wildliving ancestral species.
In addition, almost 40 percent of the pharmaceuticals used in the United States either are based on or are synthesized from natural compounds found in plants, animals or microorganisms. The array of living organisms found in a particular environment combined with the physical and environmental factors that affect them is an ecosystem. Healthy ecosystems are vital to life; they regulate many of the chemical and climatic systems that make available clean air, clean water and plentiful oxygen. Forests, for example, regulate the amount of carbon dioxide in the air, produce oxygen as a byproduct of photosynthesis and control rainfall and soil erosion. Ecosystems, in turn, depend on the continued health and vitality of the individual organisms that compose them. Removing just one species from an ecosystem can prevent the ecosystem from operating optimally.
Perhaps the greatest value of biodiversity is yet unknown. /behringer-bcd-3000-drivers-for-mac/. Scientists have discovered and named only 1.75 million species — fewer than 20 percent of those estimated to exist. Of those identified, only a fraction has been examined for potential medicinal, agricultural or industrial value.
Biodiversity for food and nutrition is a global project towards a more nutritious and resilient food system through the lens of agricultural biodiversity. Some of the major values of biodiversity are as follows: 1. Environmental Value 2. Social Value 3. Ecosystem Services 4. Economic Value 5. Consumptive use value 6. Productive Use Value 7. Ethical and Moral Value 8. Aesthetic Value. Biodiversity is the.
Much of Earth’s great biodiversity rapidly is disappearing, even before we know what is missing. Most biologists agree that life on Earth now is faced with the most severe extinction episode since the event that drove the dinosaurs to extinction 65 million years ago. Species of plants, animals, fungi and microscopic organisms such as bacteria are being lost at alarming rates. Because of this, scientists around the world are focusing their research on cataloging and studying global biodiversity in an effort to better understand it and slow the rate of loss.

As a result, the majority of current biodiversity research concentrates on preserving biodiversity and assessing environmental quality and change. Benefits of Biodiversity Biodiversity plays an important role in the way ecosystems function and in the services they provide. The following is a list of some of the benefits, or services, of biodiversity: • Provisioning services such as food, clean water, timber, fiber and genetic resources • Regulating services such as climate, floods, disease, water quality and pollination • Cultural services such as recreational, aesthetic and spiritual benefits • Supporting services such as soil formation and nutrient cycling Types of Biodiversity Biodiversity includes three main types: diversity within species (genetic diversity), between species (species diversity) and between ecosystems (ecosystem diversity). Genetic Diversity Every species on Earth is related to every other species through genetic connections.
