Should zoos cull their animals to manage populations? Liz travels to Copenhagen Zoo, who killed a giraffe and fed it to the lions, to witness their culling process first hand. They think it is a natural part of zoo keeping that is often swept under the carpet. Should some animals never be kept in captivity? In a world exclusive, Liz visits SeaWorld in Florida and asks if captivity drove one of their orcas to kill his trainer. But could zoos be the answer to conserving endangered species? Liz examines their record, from helping breed pandas for the wild to efforts to save the rhinos. She meets one of the last surviving northern white rhinos and discovers the future of this species now lies in a multimillion-dollar programme to engineer them from stem cells. Veteran conservation scientist Dr Sarah Bexell tells Liz the science of captive breeding is giving humanity false hope. 《地平线系列:我们该关了动物园吗》是一部特里斯坦·奎因导演的纪录片影片,由利兹·博宁等担纲主演,地平线系列:我们该关了动物园吗于2016正式上映,地平线系列:我们该关了动物园吗同时支持PC和手机在线观看。网站第一时间收集和整理地平线系列:我们该关了动物园吗的免费完整资源,并第一时间为大家更新地平线系列:我们该关了动物园吗的最新动态。以上是《地平线系列:我们该关了动物园吗》的剧情介绍、主演导演介绍以及资源分享,如果你觉《地平线系列:我们该关了动物园吗》好看,请分享给你的朋友一起观看!详情
