案例简介：图片由 @ katieorlinsky | 每年，数以亿计的帝王蝶从美国和加拿大旅行数千英里，以逃避在帝王蝶生物圈保护区的墨西哥米却肯州的oyamel冷杉树上的寒冷和越冬。在这里，可以找到整个越冬帝王蝶东部种群的估计70%。君主及其壮观的迁徙面临着因气温上升，干旱，栖息地丧失，马利筋 (滋养和容纳卵的植物) 和有毒农药而灭绝的风险。同时，蝴蝶和在保护区担任向导并照顾周围环境的当地人也受到威胁，既来自农业支持者，也来自针对该土地进行非法采伐的有组织犯罪。

案例简介：Photo by @katieorlinsky | Every year, hundreds of millions of monarch butterflies journey several thousand miles from the United States and Canada to escape the cold and overwinter in the oyamel fir trees of Michoacán, Mexico, in the Monarch Butterfly Biosphere Reserve. Here, an estimated 70% of the total overwintering monarch butterfly’s eastern population can be found. The monarchs and their spectacular migration are at risk of becoming extinct from rising temperatures, drought, loss of habitat, the eradication of milkweed—the plants that nourish and host their eggs—and toxic pesticides. Meanwhile, both the butterflies and the locals who work as guides at the reserve and care for its surroundings are also under threat, both from agricultural proponents as well as organized crime targeting the land for illegal logging.
