摘要
外来物种入侵最根本的原因是人类活动把这些物种带到了它们不应该出现的地方.因此,我们称这些物种是"有害的",实际上对这些物种而言是不公平的,它们只是呆错了地方,而造成这种错误的原因常常是人类的一些对生态环境安全不负责任的活动.外来入侵物种问题的关键是人为问题.
The reason for alien species intrusion is human＇s activity which has taken these species into wrong places. That we say these species harmful is unfair, for they are just in the wrong places caused by human＇s irresponsible activities to ecological environment safety. Human is the key to resolve alien species intrusion.
