The Loneliest Animals

The loneliest animals are the most endangered species on the planet. Collected and protected by dedicated scientists, these animals represent the end of the line for their species. In many cases, intensive captive breeding programs have been launched with the aim of sustaining these animals and the hope of returning them to the wild.
