John F. Calvelli, Director of the Wildlife Conservation Society (WCS)'s 96 Elephants Campaign, delivers a speech during the Ivory Crush event at Central Park in New York, the United States, on Aug. 3, 2017. Nearly two tons of ivory artifacts crafted from the tusks of about 100 slaughtered elephants were destroyed by a rock crusher in New York City's Central Park on Thursday. The event, jointly organized by the Wildlife Conservation Society (WCS) and the New York State Department of Environmental Conservation, is designed to show New York's resolution to smash illegal ivory trade.
