A ranger from the Kenya Wildlife Service (KWS) stands guard near some of around a dozen pyres of ivory, in Nairobi National Park, Kenya on Thursday, April 28, 2016.
The wildlife service has stacked 105 tons of ivory consisting of 16,000 tusks, and 1 ton of rhino horn, from stockpiles around the country, in preparation for it to be torched on Saturday to encourage global efforts to help stop the poaching of elephants and rhinos.
