Debate continues over the ethics of keeping elephants in captivity | John Wilkens

Much remains unknown about elephants, too — witness the death in December at the zoo of 48-year-old Tembo. A “sudden change” in the African pachyderm’s condition prompted keepers to euthanize her, according to zoo officials. They said she’d been under veterinary care for age-related ailments for a while. Results of a necropsy are pending. Her death came four weeks after another African elephant, M’Dunda, collapsed and died at the Oakland Zoo. She was 50 and had shown “no signs of existing medical issues, albeit her advanced age,” the zoo said. A necropsy is under way there, too. Elephants also die in the wild, of course, and often violently. But their passing in zoos raises thorny questions about what is gained by keeping them captive.
