On April 30, 2016, President Uhuru Kenyatta of Kenya set fire to the country's stockpile of confiscated elephant ivory and rhinoceros horn. It was the largest event of its kind—105 tons of ivory worth about $100 million and 1.3 tons of horn worth $67 million went up in flames. In a way, the burn was a funeral for the more than 6,000 elephants and over 300 rhinoceroses that were poached for the contraband. More important, it was a smoke signal to convey that these materials are worthless unless they are on the animals themselves, which attract tourists and play key roles in keeping ecosystems healthy.
