Alexa Westerbeck Posted almost 2 years ago Do zoos help biodiversity conservation? This is a good point. If zoos are to play a role in actively conserving species by breeding them in captivity for eventual release, it is vital that the genetic diversity is maintained in the process. I'm not sure how much this is monitored when it comes to captive breeding, but if these animals are to be released into the wild again then they must have the genetic diversity that they would have if they were breeding in the wild. Otherwise, captive breeding could end up doing more harm than good.
