(University of Zurich) Life in the wild harbors the risk of predation, food shortages, harsh climates, and intense competition. Zoo animals, by contrast, are protected from these dangers. UZH researchers were part of an international team that studied over 50 mammalian species to determine whether the animals live longer in zoos than in the wild.
