A burning pile of 15 tonnes of elephant ivory seized in Kenya is pictured at Nairobi National Park on March 3, 2015. 15 tonnes is the largest amount of contraband ivory burned in Africa to date. The fire was lit by Kenyan President Uhuru Kenyatta to mark World Wildlife Day and African Environment day. An average of 30,000 elephants are poached every year in Africa.
