A ranger from the Kenya Wildlife Service walks past 15 tons of elephant tusks which were set on fire, during an anti-poaching ceremony at Nairobi National Park in Nairobi, Kenya Tuesday, March 3, 2015. Kenyan President Uhuru Kenyatta set fire to the elephant ivory during World Wildlife Day to discourage poaching, saying that 25 years after the historic banning of the ivory trade, new demand from emerging markets is threatening Africa's elephants and rhinos.
