Orphan elephants play at the David Sheldrick Wildlife Trust (DSWT) elephant orphanage in Nairobi, Kenya on March 12, 2019. - Each calf at the nursery has a tragic story: orphaned by poachers, drought, or in conflict with humans encroaching ever further into the few wild places left. Elephants stay for about three years at the orphanage, where they are fed every three hours and sleep in individual wooden pens, each with a keeper. In 42 years, the trust has rehabilitated more than 230 orphan elephants. (Photo by Yasuyoshi CHIBA / AFP)
