News Supply and demand: White rhinos at the Entabeni Safari Conservancy, Limpopo, South Africa

Gone are the days when a “Save the Rhino” advert was enough. Only about 25,000 rhinos are left in the wild, and thanks to poaching the species is critically endangered. Now, in an effort to drive down demand, conservationists are working on campaigns to understand what makes rhino horn consumers tick.
