The Earth’s biodiversity — the variation of life at all levels — is in tremendous danger. Unique plant and animal species are dying off at record rates, jeopardizing the richness and abundance of life that took 4 million years to evolve and sustains ecological systems and humans alike.

The Center for Biological Diversity is working day and night to preserve the biodiversity we have left on Earth. Our campaigns to save species and wild places now reach beyond U.S. borders from the Antarctic to the North Pole and Asia to North Africa.

Learn how you can help and get the very latest on our work to save endangered species, from the blue whale to the gray wolf to the Mission blue butterfly, by signing up to receive our free weekly newsletter today. Your email address won’t be sold or used for anything else.
