The solution to the mystery of the monarch’s amazing ability comes at a time when it is in serious trouble. Its population has crashed by as much as 90 per cent in the last few years. Sadly, human activity is the main reason why the number of monarch butterflies is falling. In many of the places where the butterfly can be found, people are destroying the natural environment. They cut down trees and use chemicals that kill the plants that monarch caterpillars eat.
黑脉金斑蝶这一惊人能力的奥秘被揭晓时，这一生物正处于水深火热的生存状态中。其数量在近几年内减少了百分之九十之多。可悲的是，人类活动是黑脉金斑蝶数量下降的主要原因。在黑脉金斑蝶生存的许多地方，人们正破坏着那里的自然环境。他们砍伐树木，他们所用的化学制剂杀死了黑脉金斑蝶幼虫食用的植物。

The research on the monarch’s behaviour has however led to a greater awareness of this creature. People have been working together to record its migration and make sure that there are enough plants for it to feed on. If this works, there may come a time when the number of monarch butterflies increases once again. The more we know about this lovely creature, the greater the chance it will survive and keep its place in the natural world for a long time to come.
不过，对黑脉金斑蝶行为的研究也使得人们对这种生物有了更多的认识。人们已经在共同努力，记录它的迁徙，并确保它有足够的食物。如果这些努力产生效果，黑脉金斑蝶的数量在未来有可能会再次回升。我们对这个可爱的生物了解越多，它们在自然界中得以长久生存并保持其地位的可能性就越大。
