Protecting the Earth’s amazing diversity of animals and plants is the Center for Biological Diversity’s core mission. From miniscule, near-invisible fairy shrimp to gray whales and towering redwoods, we believe all species have an intrinsic right to live.

And we’ve put that belief into motion: In the past 20 years, the Center has saved more than 500 plants and animals and more than 120 million acres of habitat. But there are many more species and acres to protect, and we can’t do it without you. Your financial contribution will help us save wolves, whales, owls, snails, and hundreds of other species great and small.

The Center is one of the most cost-effective — if not the most cost-effective — endangered species group in the country. We've been top-rated by the American Institute of Philanthropy. So you can rest assured your donation will go straight toward preserving the astounding biodiversity that comprises ecosystems around the world and sustains human life.
