　　Longer Lives for Wild Elephants

　　Most people think of zoos as safe places for animals, where struggles such as difficulty finding food and avoiding predators (猛兽) dont exist. Without such problems, animals in zoos should live to a ripe (成熟的) old age1.

　　But that may not be true for the largest land animals on Earth. Scientists have known that elephants in zoos often suffer from poor health. They develop diseases, joint problems and behavior changes. Sometimes, they even become infertile, or unable to have babies.

　　To learn more about how captivity (圈养) affects elephants, a team of international scientists compared the life spans of female elephants born in zoos with female elephants living outdoors in their native lands. Zoos keep detailed records of all the animals in their care, documenting factors such as birth dates, illnesses, weight and death. These records made it possible for me researchers to analyze 40 years of data on 800 African and Asian elephants in zoos across Europe. The scientists compared the life spans of the zoo-born elephants with the life spans of thousands of female wild elephants in Africa and Asian elephants that work in logging camps(伐木场),over approximately the same time period.
