In this Tuesday, Feb. 19, 2013 photo, a team from the Kenya Wildlife Service (KWS) and the International Fund for Animal Welfare (IFAW) fit a GPS-tracking collar onto a tranquilized 26-year-old male elephant, to monitor migration routes and to help prevent poaching, at the Kimana Wildlife Sanctuary next to Amboseli National Park in southern Kenya, near the border with Tanzania. Tanzania, Botswana, the Central African Republic, Chad, Congo and Kenya are suffering from elephant poaching. But Iain Douglas-Hamilton, the founder of the London-based nonprofit Save The Elephants, says he is most worried about Tanzania's because of its huge population - somewhere between 40,000 and 70,000.
