4、it possible for the 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 camps3,

5、over approximately the same time period.The team found that female African elephants born in zoos lived an average of 16.9 years. Their wild counterparts who died of natural causes lived an average of 56 years more than three times as long. Female Asian elephants followed a similar pattern. In zoos,

6、 they lived 18.9 years, while those in the logging camps lived 41.7 years.Scientists dont yet know why wild elephants seem to fare so much better than their zoo-raised counterparts.

While some threaten
