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.

Endangered ocelots are highly territorial, requiring miles of dense habitat for hunting. Habitat fragmentation from agriculture and development is their greatest threat. Learn more about ocelots: biologicaldiversity.org/species/mammals/ocelot

The Center for Biological Diversity is a Tucson-based 501c3 nonprofit. We believe human welfare is deeply linked to nature's diversity. Through science, law, and creative media, we work to protect lands, waters, and climate, securing a future for all species on the brink of extinction.
