NPR's Scott Simon talks with Ginnette Hemley of the World Wildlife Fund about a controversy brewing over two elephants at the Los Angeles Zoo. In the coming month, the Los Angeles Zoo plans to transfer an African elephant named Ruby to the Knoxville Zoo in Tennessee. For the past 16 years, Ruby has lived with an Asian elephant named Gita. An L.A. Zoo patron contends that both elephants will suffer needlessly if they are separated. She has filed a lawsuit in hopes keeping Ruby in Los Angeles.
