Fishing boats lie unused on the dried up bed of lake Poopo in the Oruro Department, south of La Paz, in Bolivia. Lake Poopo is a large saline lake and was the Andean nation's second largest after the famed Titicaca. Now its water has disappeared entirely. The lake was full of endemic species but animals have died off in their millions, according to studies. Locals dependent on the lake for survival have been forced to leave.
