They say that elephants never forget. Joyce Poole believes it--and, she says, elephants are far more like humans than most of us realize. Poole came to Kenya to study elephants in 1975 as a 19-year-old. She fell in love right away and spent years getting to know the animals at Amboseli National Park. But something was nagging away at her: while she was learning more and more about some of the most fascinating animals on earth, poachers were wiping out many thousands of African elephants. So Poole quit Amboseli for a short but wildly successful career in the Kenya Wildlife Service, where she helped draft policies that would fight poachers. Now Poole is back at Amboseli, learning more about the elephants that have become her close friends over the years.
