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.

To us, every day is Endangered Species Day. The extinction crisis looms over our planet, threatening everything from whales in our oceans to wildflowers in the desert, wolves in the mountains, and butterflies in our backyards. For the past 37 years, the Center for Biological Diversity has stood on the front lines fighting for species big and small — in the courts, in communities, and in the wild places they call home. We’ve helped win protections for hundreds of imperiled species and more than 700 million acres of habitat because every species matters. Every wolf pack. Every sea turtle hatchling. Every ancient redwood tree. Every living thing fighting to survive in a rapidly changing world. This work has never been more urgent. But hope for the future is in the work we d Because when people come together to fight for the wild, we win. And we will never stop fighting for a future where endangered species are not just remembered — but alive, thriving, and protected for generations to come. For the wild. 🌎
