Biodiversity is the number and variety of living organisms within a specific geographical region. These organisms work together to create a thriving and productive ecosystem. The term can relate to the simplicity or diversity of genes or species.
Biological diversity refers to a specific habitat and how the number of species relates to all organisms in the environment. This includes flora and fauna relationships and how they coexist with each other.
Conservation is planned management of a natural resource to prevent exploitation, destruction, or neglect. The goal of conservation is to educate the public on the true needs of the society and how to conserve scarce resources, while having the ability to exist in the world.
Even though the term biodiversity is fairly new to the public’s vocabulary, the diversity of our world dates back millions of years ago. Scientists figure that the diversity of the earth has been inconsistent. There have been massive extinction events. Our earth started out with single celled organisms; later multicellular organisms appeared. Scientists tend to have their own views about the species inventory. Estimates seem to range around ten million species.
Thomas Lovejoy coined the term biological diversity in 1980, while W. G. Rosen coined the word biodiversity itself in 1985. (Answers.com)
At the United Nations Earth Summit in Rio de Janeiro in 1992, 150 countries signed the Convention on Biological Diversity. This signified that action must be taken to halt the global loss of plant and animal species and genetic resources. These countries agreed to create national strategies, plans and programs for conservation and sustainable use of biological diversity. (History of Biodiversity)
Without biodiversity food, medications, industry, habitats, and ecosystems will falter. A habitat in equilibrium has a balance between the number of species present and its resources. The more pristine a diverse habitat, the better chance it has to survive a change or threat—either natural or human—because that change can break the food chain with removal of a single species.

Biodiversity is what underlies many important ecological goods and services that provide benefits to humans. It is a benefit for daily life and a field of activity and profit. But a species can also have a value in and for itself, which is why many biologists feel we should try and save all species.
Biodiversity helps scientists understand how life functions and the role of each species in sustaining ecosystems. E.O. Wilson wrote in 1992 that, “The biodiversity is the one of the bigger wealths of the planet, and nevertheless, the less recognized as such.” (Answers.com)
If humans continue to cause extinctions of species, whether plants, animals or insects, the global ecosystem is destined for collapse due to the reduction of the biological complexity. The introduction of exotic species is causing extinction of species, which reduces biodiversity, and in turn weakens our ecosystem and makes it more vulnerable to collapse. (Answers.com)
Ties to the Philanthropic Sector
Governmental agencies have limited resources for the protection of our biodiversity. They tend to put a value on species and protect that species unless costs are too high. Also, governmental agencies tend to focus on inventory of species instead of focusing on the processes that have created and sustained the species and on elements that currently exist, rather than on the species and elements themselves. (Stanford)
Many nonprofits fund organizations that try to preserve the world’s ecosystems and habitats. Research centers identify high-risk habitats, plants and animals, and nonprofits invest in their conservation, preservation and protection.
For example the World Wildlife Fund (WWF) has focused on how to produce the maximum yield in agriculture while conserving biodiversity. The destruction of tropical forests for agricultural land, logging, urbanization, or livestock is a major concern for conservationists. Nonprofit organizations like WWF have tried education, protection, restoration, policy changes, and incentives to reduce the destruction of the biodiversity of rainforests.
Key Related Ideas
Ecological biodiversity is also the diversity of durable interactions among species. It is how the organisms apply to the environment they live in. In each ecosystem, living organisms are part of a whole; they interact with one another, but also with the air, water, and soil that surrounds them. (Answers.com)
Ecosystem diversity is diversity at a higher level of organization, the ecosystem. This concept reveals the relationship of plants and animals and how they survive without becoming extinct. (Answers.com)
Encourage Sustainable Trade is a belief that we humans can live and survive in this world without exhausting all of its resources.
Education of the general public on the cause and effect of the goods they purchase is vital to have a sustainable living environment.

Norman Borlaug (March 25, 1914 —): Borlaug won the Nobel Peace Prize in 1970. He spent many years studying and developing new wheat for growth on formally unproductive lands, which was called the “Green Revolution”. One of his goals was to develop new cereals strains into massive production in order to feed the hungry people of the world. Borlaug’s work helped prevent starvation and malnutrition across the globe. (Answers.com)
Rachel Louise Carson (May 27, 1907 — April 14, 1964): Carson was a published writer, scientist, and ecologist. She documented many articles on conservation and natural resources. She published her prize-winning study of the ocean, The Sea Around, and other books, which made her famous as a naturalist and science writer. She resigned from government service to educate people about the world of living things. Later in life she focused her attention on the misuse of pesticides and their unknown health effects. In 1962 publication of Rachel Carson’s book, Silent Spring, documented how the insecticide DDT accumulates in the environment and harms mammals and birds. Her book helped start the environmental movement. (Answers.com)
