Liz Bonnin presents a controversial and provocative episode of Horizon, investigating how new scientific research is raising hard questions about zoos - the film explores how and why zoos keep animals, and whether they need to change to keep up with modern science or ultimately be consigned to history.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.

利兹·博宁在《地平线》中展示了一个富有争议和挑衅性的事件，调查了新的科学研究如何对动物园提出了尖锐的问题——这部电影探讨了动物园如何以及为什么饲养动物，以及他们是否需要改变以跟上现代科学的步伐，还是最终被委托历史。应该动物园为了管理种群而宰杀动物？利兹前往哥本哈根动物园，后者杀死了一只长颈鹿并喂给狮子，亲眼目睹了它们的扑杀过程。他们认为这是动物园饲养的一个自然组成部分，经常被掩盖起来。有些动物不应该被关起来吗？在一个世界独家报道中，莉斯访问了佛罗里达的海洋世界，问他们是不是被囚禁驱使他们的一只虎鲸杀死了他的教练。但是动物园能成为保护濒危物种的答案吗？利兹检查了他们的记录，从帮助野外繁育熊猫到拯救犀牛。她遇到了仅存的一只北白犀牛，发现这个物种的未来在于一个数百万美元的项目，用干细胞来改造它们。资深自然保护科学家莎拉·贝塞尔博士告诉莉斯，圈养繁殖的科学给人类带来了虚假的希望。
