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.　　王老爷是护宝人，为此他三十年未曾离开王家半步，因为高墙之外，夺宝之人也从未停止觊觎，更多敌人正源源不断从四面八方向此聚拢，更紧迫的是，日寇的战火已经燃起。20世纪30年代的大上海，顾家四兄弟携手进军影视界。顾家老幺顾延枚，为了兄长们的事业，跟随三哥南下新加坡开拓南洋电影市场，从此注定其一生与电影业的不解之缘。恰逢二战，时局骤变，顾氏兄弟将制片基地迁至香港。战争结束，香港百废待兴，兄长们将香港影厂托付给顾延枚。面对今非昔比的电影市场，顾延枚始终视观众为自己制作影片的源动力，终于造就顾氏兄弟电影成为香港第一家，不单令香港影圈星光闪耀，更成亚洲一时之冠。其声望日隆，被尊为“华语影视大亨”。因多年来乐善好施，热心公益，顾延枚也成为世界公认的大慈善家。华鲁女子监狱的年青警官海兰与她所领导的分监区是一个出色的青年巾帼集体。海兰与她的战友们情同姐妹，始终任劳任怨、默默无闻的工作在女子监狱的第一线，用她阳光灿烂般的真挚热情，用她们的智慧、勇敢、执着以及与时俱进、科学先进的管教理念和具体可行的管教方法，使许许多多在人生坦途中犯了各种罪行的女服刑人员在各自的劳动与改造过程中，充分领略到中国法律的威力与公正性，逐渐完成了一个人从犯罪转变为正常自由人的艰难过程，同时在这个过程中充分体味到生命、复活、新生的人生意义。森林里住了好多精灵，白衣精灵是正派，黑衣精灵是反派， 在一次战役中，白衣精灵损失惨重，白衣精灵女主意外混入人类当中并且控制一个魔法一般的床，在人类世界女主在茫茫人海中遇到了男主并彼此相爱，与男主在一起过程中遇到不少的挫折，女主能否重新振兴白衣精灵消灭敌派黑衣精灵并且和男主终成眷属呢？刚刚因为赵地还有成皋的事情得意，巴蜀就开始让人烦心了。
