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.Mathematics:三轮这样的炮击后，安文港几乎没有什么损失，五艘战舰就此更加接近一些，进入200码范围内，还未及排开阵列，港口这边已经率先开炮，三十门火炮齐轰，落点已经离葡萄牙舰队很近了，但还是遗憾落入海中。《都市侠盗》类似现代版的罗宾汉与《十一罗汉》的综合体，讲述了一群各怀绝技的飞天大盗行侠仗义的故事。奥斯卡奖获得者Timothy Hutton出演男一号。该剧由Dean Devlin（《独立日》， 《图书管理员》）任导演， John Rogers（《变形金刚》，《地心末日》）和 Chris Downey（《后中之王》）编剧，并由Devlin和Roger共同监制。TNT高级策划Michael Wright看了试播集后这样评论本剧，“《都市侠盗》是一部节奏紧凑，构思巧妙，诙谐有趣的好剧；Timothy Hutton是一个非常杰出的演员，他和他的伙伴表演的很有火花：这是一部取得了突破性成绩的电视剧，与Dean合作我非常开心。”剧中Hutton 饰演的Nate Ford，是一个为他的雇主找回丢失货物的白金保险调查员：在他的公司拒绝为他将死的儿子支付保险金之后，辞掉了工作成为一名自由职业者，而他的第一份工作是为一名航空工程师找回被盗的飞机设计。出演该剧的明星还有Beth Riesgraf 《艾尔文与花栗鼠》，Christian Kane （《天使》，《律政俏主妇》），Aldis Hodge （《胜利之光》）以及Gina Bellman （《冤家对对碰》，《化身博士》），他们在剧中都是“纳特一伙”的成员。Mullenathan and Shafir put forward the concept of "bandwidth".
