Zambia's Vice-President Guy Scott (C) and IUCN general director Julia Marton-Lefevre stand on the opening day of an emergency elephant summit by the International Union for Conservation of Nature in Botswana, on December 3, 2013 in Gaborone. Africa could lose 20 percent of its elephant population within a decade, conservation groups warned on December 2 as governments met in Botswana to discuss measures to curb poaching. The meeting is expected to adopt 13 "urgent" steps to stem the tide of illegal elephant killings. AFP PHOTO/MONIRUL BHUIYAN        (Photo credit should read Monirul Bhuiyan/AFP/Getty Images)
