《寂静的春天》读后感——化学农药的使用:利益与危害的博弈

Use of Chemical Pesticides:the Game Between Benefits and Harms

化学合成农药是人类科技进步的产物,大量使用至今已有70多年历史,但由于对化学农药缺乏科学、客观的认识,并随着人们生活品质和环保意识的提高,仍然有很多人对化学农药存在“恐惧”。化学农药作为一种对有害生物具有活性的物质,不可避免会对生态环境产生或多或少的负面影响,然而关注其缺点的时候常常会忽视他对保障粮食生产安全和提高作物品质方面发挥的巨大作用。化学农药的使用,正是在利益与危害间的博弈,但化学农药在发展过程中也在不断的改进和提高,一些高效低风险农药陆续取代了过去高风险、长残留农药,正在趋利避害的过程中不断前进和发展。

Chemical synthetic pesticides are the product of the progress of science and technology,and have been widely used for more than 70 years.However,due to the lack of scientific and objective understanding of chemical pesticides,and with the improvement of people's life quality and environmental protection awareness,there are still many people who have“phobia”about chemical pesticides.Chemical pesticides,as a kind of biological active substances to harmful organisms,will inevitably have more or less negative effects on the ecological environment.However,when we pay attention to chemical pesticide’s shortcomings,we often ignore their great role in ensuring food production safety and improving crop quality.The use of chemical pesticides is the balance between benefits and hazards.However,chemical pesticides are constantly improving and improving in the development process.Some high-efficiency and low-risk pesticides have gradually replaced the high risk and long-term residual pesticides in the past,and are developing in the process of pursuing advantages and avoiding disadvantages.
