AFP PICTURES OF THE YEAR 2016 This picture shows one stack of burning elephant tusks, ivory figurines and rhinoceros horns at the Nairobi National Park on April 30, 2016. Kenyan President Uhuru Kenyatta set fire on April 30, 2016, to the world's biggest ivory bonfire, after demanding a total ban on trade in tusks and horns to end "murderous" trafficking and prevent the extinction of elephants in the wild. / AFP PHOTO / FREDRIK LERNERYD
