23、方式。“我们不是在试图拯救动物，”他说。“事实上，我们是 在拯救自己。” 二十世纪八九十年代是藏羚羊的艰难时期。 数量下降了 50%以上。 猎人们猎 杀藏羚羊以获利。因为新的公路和铁路的修建，它们的栖息地变得越来越小。 为了拯救这一物种免于灭绝，中国政府将其置于国家保护之下。扎西和其他 志愿者日夜守护着这些藏羚羊，保护它们免受攻击。公路和铁路上的桥和门增加 了，让藏羚羊容易行动，使它们安全，远离汽车和火车。 这些措施是有效的。藏羚羊的数量一直在恢复，2015 年 6 月，藏羚羊从濒 危物种名单中被移出。然而，政府并没有打算停止这些保护项目，因为对藏羚羊 的威胁依然存在。 在晚上，我喝着茶，仰望着星空。我想起了藏羚羊以及扎西对我说的话。我 们在保护野生动物方面做了很多工作，但是如果我们真的想拯救地球，我们必须 改变我们的生活方式。只有学会和大自然和谐共处，我们才不会成为野生生物和 地球的威胁。
