按我们一般人的常识,对害虫是要赶尽杀绝、绝不能手软的。记得小时候看过一则广告,广告词是:“我们是害虫,我们是害虫,正义的杀虫灵,正义的杀虫灵,一定要把害虫杀死、杀死!”不过在美国的许多农田里,人们却特意为害虫们留了一些“避难所”。“避难所”里虽然食物不多,却不至于让害虫全部饿死、绝种。难道是美国人心慈手软,要对害虫实施“虫道主义”救助? According to the common sense of our common people, it is necessary to exterminate the pests and must not be soft-handed. I remember reading an ad child, the ad is: “We are pests, we are pests, the insecticide of justice, the insecticide of justice, we must kill pests, kill!” However, in the United States In many fields, people deliberately left some “shelters” for pests. “Refuge ” Although not much food, but not let all the pests starved to death. Is it that Americans are merciful and want to implement “worms” for pests?
