Global environmental crime is estimated by the United Nations to be worth as much as $213 billion annually. Over $23 billion is attributed to the illegal wildlife trade alone, of which ivory is an important component. Across Africa, as much as 5-7% of the elephant population is being slaughtered annually by a wide range of highly militarized actors, closely tied to conflict, organized crime, and political corruption. The price of ivory has skyrocketed from USD $5/kg in 1989 to a wholesale price of USD $2,100/kg in China in 2014, with retail prices much higher. To achieve this value, a trafficking organization must source, consolidate, transport, and sell ivory along an extremely long and complex supply chain that crosses borders and oceans and travels from the remotest corners of Africa thousands of miles to retail markets in Asia. Out of Africa investigates the global ivory supply chain to find that the illegal trade has consolidated and professionalized with the large majority of profits accruing to transnational organized crime. Between 2009 and June 2014, these criminal networks trafficked as much as 170 tons of ivory, which could amount to as many as 229,729 elephants.
