主题：What animal or insect do you wish humans could eradicate?

I don’t think we should eradicate any. Some people might suggest mosquitoes and wasps. True they do cause problems, but mosquitoes are a major food source for many fish. Common wasps eat many insects and are good for the garden, in spite of the fact that they eat fruit in the autumn. Taking out any animal will upset the ecosystem. Control, yes, but eradication, never.

Eradicate: 消灭，根除
Mosquitoes：蚊子
Wasps：黄蜂
