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.Believe in the danger of natural talent//292阿部润漫画《老爸的第二春》真人影视化，将推出8集电视剧集，小泽征悦领衔主演，明年2月1日播出。故事发生在一个由尼特族兼家里蹲的爸爸、食量大且偶尔还会猫化的爷爷、再加上外表是大叔的妈妈的家庭里，女儿山下朋的生活被这些不平凡的家人搞得充满风波。先前谁想到这个，这不是昨晚才决定的么。军中形式复杂，你我都需谨慎小心。Do you really practice deliberately?No.63 Bank
