Stress and lack of exercise are killing elephants, zoos warned
Animal welfare officers yesterday urged zoos to phase out keeping elephants, after two damning reports found the animals suffer serious health problems and die much younger in captivity.

Elephants born and raised in zoos live less than half as long as those living in their native Africa and Asia, despite being protected from predators and having better care, according to one of the reports.

Many of the deaths are thought to be linked to obesity, because the animals are well fed but get very little exercise in their small enclosures. Scientists also blamed high stress levels, which the animals suffer most after being transferred between zoos and being separated from their mothers.
