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.

The Buzz on Western Bumblebees
February 08, 2026

One in four native bee species, including western bumblebees, are rapidly declining due to habitat loss, climate change, invasive species, and pesticides. This alarming trend signals significant biodiversity loss across the country.

The Center for Biological Diversity, a 501c3 nonprofit, protects species and their habitats through science, law, and creative media. Believing human welfare is deeply linked to nature, we work to secure a future where the wild thrives for generations to come.
