英语新闻听写 生物学家发现降解塑料袋的方法-让毛毛虫吃了它（在线收听）

A developmental biologist and amateur beekeeper has come up with a new way to get rid of used plastic bags: Make waxworms eat them. The larvae of the greater wax moth, these caterpillars thrive on beeswax.

一名发展生物学家及业余养蜂人想出了一种摆脱废旧塑料袋的新方法：让腊虫吃了它们。大蜡螟的幼虫--这些毛毛虫依靠蜂蜡成长。

It turns out the caterpillars can actually break down the bag's polyethylene into ethylene glycol, which can be readily converted into useful substances such as antifreeze. Polyethylene is very hard to break down, making the 80 tons produced a year a big recycling challenge but it seems a solution may be in reach.

事实证明这些毛毛虫能把塑料袋里的聚乙烯分解成乙二醇，这样就能将其转变成防冻剂之类的有用物质。聚乙烯很难分解，每年会生产出80吨聚乙烯，这在循环上是个难题，不过看似就要有解决方法了。
