23、appy ending.返首页30 译文参考 麦夸里岛：从大混乱到受保护我站在麦夸里岛上，该岛在西南太平洋，位于澳大利亚和南极洲的中间。强风和波涛汹涌的大海帮助塑造了它细长的外形。青草和光秃秃的岩石形成了鲜明的对比，使它具有一种野性和自然的美。没有游客会对该岛是联合国教科文组织评定的世界自然遗产感到惊讶的。他们也会去想象岛上的栖息动物，包括皇家企鹅、王企鹅和象海豹，是如何与自然栖息地和谐共存数千年的。返首页31 但岛上最近的历史却讲述了一个不同的故事。这是一个悲惨的故事，始于 1810 年人类来到岛上。他们无意中把老鼠带上了船。这些小动物很快占领了这个岛，吃鸟蛋并袭击小鸟。猫被带到岛上以控制老
24、鼠。不幸的是，猫后来也对鸟产生了食欲。返首页32 同时，兔子作为人的食物来源被引进岛上。在岛上自由自在，它们尽其所能迅速繁殖，开始吃当地的植被并挖洞，造成水土流失。激增的兔子为猫提供了大量的食物，这意味着猫的数量也在增加。这反过来又导致更多的猫捕鸟。最终的结果是，曾经数量众多、原产于该岛的长尾鹦鹉于 1891 年灭绝。返首页33 即使麦夸里岛在 20 世纪 70 年代成为正式的自然保护区后，兔子的数量仍然无法控制。专家们认为有必要想出一个计划，除掉岛上的所有兔子。考虑到这个目标，一种病毒被释放到岛上。尽管病毒导致兔子数量从 13 万只减少到 1 万只左右，但也意味着猫的食物减少了。结果，这些猫
25、把注意力又转移到了当地的鸟类身上，它们又吃起鸟来每年捕杀的鸟多达 6 万只。上世纪 80 年代，人们用陷阱和狗来捕猫。最后一只麦夸里岛猫是在 2000 年被捉住的。返首页34 但俗话说，“猫儿不在，老鼠作怪。”随着猫离开小岛，老鼠的数量开始增加。还记得那 1 万只左右的兔子吗？结果他们对病毒产生了免疫力，他们的数量再次激增。然后，在 2006 年，兔子的挖掘导致一些土地塌陷，大量企鹅死亡。这一事件表明，鼠兔问题需要一劳永逸地解决。返首页35 所以，我在麦夸里岛这里参与处理这个问题的方案。第一步是从直升机上投下了毒药。下一步是要清除最后一个入侵物种，这就是我的切入点带着我的狗。它们被训练在不伤害当地动物的情况下找到最后一个。这种干预是漫长的，延迟的一个悲伤故事的结局。但我们人类有义务给这个岛一个圆满的结局。Thank you for watching!
