Black rhinos are not actually black. They are, however, giant animals with tiny eyes, feet the diameter of laundry baskets, and horns that are prized for both their aesthetic and medicinal qualities. Until recently, these creatures were perched on the edge of extinction, their numbers dwindling as they succumbed to poachers and the ravages of civil war. Now their numbers are rising, thanks to a groundbreaking new conservation method from the Save the Rhino Trust: make sure that rhinos are worth more alive than dead.
