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.

For us, every day is Endangered Species Day. The extinction crisis threatens countless species, from whales to wildflowers. For 37 years, the Center for Biological Diversity has fought on the front lines, securing protections for hundreds of imperiled species and over 700 million acres of habitat. We believe every living thing matters.

Our work has never been more urgent. Hope lies in collective action; when people unite for the wild, we win. We are committed to ensuring endangered species not only survive but thrive, protected for generations to come.
