In a food waste recycling plant in Zhangqiu district in Jinan, Shandong Province, piles of food waste, freshly delivered here from local restaurants and canteens, are waiting to be recycled - by cockroaches. 在山东省济南市章丘区的一间食品垃圾回收工厂里，从当地餐馆和食堂刚送过来的成堆食品垃圾正在等待着被蟑螂回收利用。 After being ground, the food is pumped into glass containers in the plant through a pipe, then devoured by millions of cockroaches. 在被磨碎之后，这些食物通过管道输送到工厂里的玻璃容器中，然后由数百万只蟑螂吞食。 For most people, cockroaches are pests that can leave an offensive odor, transmit viruses on their body surfaces and taint food. 对于大多数人来说，蟑螂是一种可以留下异味、传播身体表面的病毒并且污染食物的虫子。 |
