About This Collection

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.

Brown Bears in the Tongass National Forest
March 24, 2026

The Tongass National Forest, a vast old-growth rainforest and home to Alaskan black bears, is a crucial natural defense against the climate crisis. The Center for Biological Diversity, a 501c3 nonprofit, works to protect such vital ecosystems and secure a future for all species, recognizing that human welfare is deeply linked to nature's diversity.

Through science, law, and creative media, we focus on protecting the lands, waters, and climate species need to survive, ensuring future generations inherit a world where the wild is still alive.
