White rhinoceros (Ceratotherium simum) conservation. Children from a local village observe a rhinoceros de-horning operation at the Kwenga Lodge Private Game Reserve, South Africa. The horn, which is made entirely from keratin protein, is removed with a chainsaw at ten centimetres above the base. Rhinoceros horns are used as ornaments and for some traditional medicines. Despite horn removal, rhinoceroses are still killed by poachers. It is hoped the de-horning session will educate the local community about rhinoceros conservation.
