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.

Protect Redwoods from Highway Expansion
April 12, 2026
Some of California’s most iconic redwoods are at risk — not from logging, but from a highway expansion through protected public lands. Right now, plans to expand Highway 101 would cut into the root systems of ancient trees on the North Coast. These roots are essential to their survival. When they’re damaged, trees can weaken, decline, and die. Less than 5% of original redwood forests remain. These groves support entire ecosystems and can’t simply recover once they’re damaged. Governor Gavin Newsom has the authority to step in and stop this from moving forward. Tell Newsom: Protect redwoods before it’s too late. https://act.biologicaldiversity.org/Q8zhKD6k_0WPC_R3viC_KA2
