Genetic make up of captive species may be so different to wild that they can’t interbreed

Detailed explanation-1: -Even a lifetime in the most humane zoo will have left animals too affected by years of sheltered existence. Captive animals seldom learn crucial survival skills and often are too habituated to human contact. Lacking a natural fear of humans, they are vulnerable to poachers and ill equipped for life in the wild.
Detailed explanation-2: -Genetic diversity is reduced (fewer breeding partners) Some species born in captivity may not be able to be released into the wild as they wouldn’t cope (can’t hunt for food efficiently) Environments in zoos will never be as large or as ‘natural’ as the animal’s native habitat so may affect animal’s behaviour etc.
Detailed explanation-3: -Breeding helps to increase the size of a threatened species population-and captive breeding provides our animals with a safe space to breed and allows young animals to become strong and resilient, before we release them into the wild.
