Photographer Tim Flach explores one of the most pressing issues of our time in an extraordinary multiyear project to document the lives of threatened species. Traveling around the world to settings ranging from forest to savannah to the polar seas to the great coral reefs, Flach has constructed a powerful visual record of remarkable animals and ecosystems facing harsh challenges. Primates coping with habitat loss, big cats in a losing battle with human settlements, elephants hunted for their ivory, and numerous bird species taken as pets. With zoologist Jonathan Baillie providing insightful commentary on this ambitious project, this is a series of vivid, interconnected stories that pose gripping moral dilemmas, unforgettably expressed by more than 180 incredible images. Tim Flach is the author of Dogs, Equus, and More than Human. Dr. Jonathan Baillie is chief scientist of the National Geographic Society. Flach and Baillie live in London.
