About This Website

Biodiversity refers to the variety of life in the world or in a particular habitat or ecosystem. It is necessary for life to thrive on Earth.

Aldo Leopold, one of the great thinkers of conservation, observed more than half a century ago the importance of protecting species. "To keep every cog and wheel is the first precaution of intelligent tinkering," he wrote. Losing species is like throwing away one by one the engine parts of an airplane while flying.

Biodiversity is a major initiative of Conservation International.

Biodiversity conservation provides substantial benefits to meet immediate human needs, such as those for clean, consistent water flows; protection from floods and storms; and a stable climate.

Polar Bears Drowing in Arctic (PSA 2014)

Global warming is killing polar bears. As their sea-ice habitat disappears, bears are drowning, starving to death, and in some desperate cases, even eating each other.

It doesn't have to be this way. With your help, the Center for Biological Diversity can educate and inspire 100 million people to take action to save polar bears.

In 2010 the Center won the Top Ten Award for our polar bear public service television ad, reaching a record 90 million people. This year we have a powerful new ad, and we need your help to inform 100 million people about the polar bear's plight.

Help us get the message out while polar bears still have a chance. We've been top-rated by the American Institute of Philanthropy, and you can trust us to make the most of your tax-deductible donation. Please call toll-free (866) 357-3349 x323. You can also mail a check to: Center for Biological Diversity, PO Box 710, Tucson, AZ 85702
