For many of Earth’s creatures, time is running out. Half of the world’s plant and animal species will soon be threatened with extinction. The goal of the Photo Ark is to document biodiversity, show what’s at stake and to get people to care while there’s still time.  More than 2650 species have been photographed to date, with more to come.
