徐风坚定的视线太过强烈，逼得季木霖不得不挪开了视线。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.半晌才道：我想见见丞相？其实他自己也弄不清楚，为何想要见赵高。全无分别，既能独立存在。钧天立国三百载，传至启昆帝，他虽贵为天下共主，但国势渐微，对各属国控制已大不如前，而以「北斗七星」为名的诸侯国，就属天权、天璇、天枢、 天玑实力最强。众人一想也是，都松了口气。Proxy: Proxy is also a group of hosts that attackers invade and control.
