The Center for Biological Diversity is a Tucson, Arizona-headquartered 501c3 nonprofit. We believe human welfare is deeply linked to nature—to the vast diversity of wild animals and plants. Recognizing diversity's intrinsic value and the societal impoverishment caused by its loss, we work to secure a future for all species on the brink of extinction.

We achieve this through science, law, and creative media, focusing on protecting the lands, waters, and climate essential for species survival. Our ultimate goal is for future generations to inherit a world where the wild still thrives.
