This Campaign Has Ended

The Photo Ark uses the power of photography to inspire people to help protect at-risk species before it’s too late. National Geographic Explorer, photographer and founder of the Photo Ark Joel Sartore has taken portraits of 18,000 species — and counting — in his quest to document our world’s astonishing biodiversity. He’s over half way to his goal of documenting over 25,000 species living in the world’s zoos, aquariums and wildlife sanctuaries.
