美国农民长期以来认为少用农药会导致作物减产,并因此造成食品涨价。但经对现在主要依靠化学方法治虫的效益和成本进行综合分析,有力证明并非如此。康乃尔大学的研究人员分析了有关作物产量和农药使用资料后,得出如下结论:如果现在施于作物的一半化学药品,能由其它控制技术代替的话,产量不会下降,而且食品价格上升将不足1％。该研究成果证实关心农药污染的消费者正在增长,并强强一种更加有机化的农业方 Peasants in the United States have long believed that less use of pesticides will result in a cut in crop yields and as a result, higher food prices. However, a comprehensive analysis of the benefits and costs of relying mainly on chemical pest control now proves otherwise. Cornell researchers analyzed data on crop yields and pesticides to conclude that if half of the chemicals now in the crop could be replaced by other control technologies, yields would not fall and the rise in food prices would Less than 1%. The findings confirm that consumers who are concerned about pesticide contamination are growing and that a more organic farming party
