使用化学农药确实能使农业增产,但也给人类带来了灾难。其危害是多方面的,而且越来越重。世界各国经过长期的实践都证明了这一点,对此,我们必须对化学农药的生产及使用加以限制和改进。造成环境污染.由于长期滥用化学农药,就出现了农药公害。目前,世界各国实际生产和应用的化学农药品种已增加到500种以上,大量生产的就有100多种。全世界化学农药的总产量已达150—200万吨。 The use of chemical pesticides can indeed increase the output of agriculture, but it also brings disasters to human beings. Its harm is multifaceted, and more and more heavy. This has been proved by the long-term practice of all countries in the world. To this end, we must limit and improve the production and use of chemical pesticides. Resulting in environmental pollution due to the long-term abuse of chemical pesticides, there have been pesticide pollution. At present, the actual production and application of chemical pesticides in various countries in the world have increased to more than 500 species, with over 100 species being mass-produced. The total output of chemical pesticides in the world has reached 1.5-2 million tons.
