The interaction between animals and their environments is the engine that keeps the planet healthy for all of us. But for many species, time is running out. When you remove one, it affects us all.

The National Geographic Photo Ark is a multiyear effort to raise awareness of and find solutions to some of the most pressing issues affecting wildlife and their habitats. Led by National Geographic photographer, Fellow, and 2018 Rolex National Geographic Explorer of the Year Joel Sartore, the project aims to document every species living in the world’s zoos and wildlife sanctuaries, inspire action through education, and help save wildlife by supporting on-the-ground conservation efforts.
