Zakouma National Park, Chad, 2006
A century ago, there were more than a million elephants in Chad. A recent survey tallied about four hundred. The attrition is caused primarily by the ivory market. In China, the world’s fastest-growing consumer, dealers sell ivory over the Internet. The Janjaweed, known locally as the “Devils on Horseback,” killed this elephant within earshot of patrolling guards, photographed here, but were not caught.
