第六辑以一名当地知名人士被谋杀为中心，这起案件触动了设得兰群岛及其人民的心。随着佩雷斯和他的团队揭开了谋杀动机的万花筒，他们的调查很快发生了令人震惊的邪恶转变。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.这天，陈启上网看了一会儿新闻后，刚准备码字，这时突然听到外面有声响传来。黄鳝已经被泥鳅狠狠训了一顿，闻言不敢吱声。九江王，贵我两国结盟联合反楚的事情我会尽快禀报给汉王，汉国和九江国从东西两线同时出兵反攻楚国。三更求粉。
