DDT是第一个重要的有机氯杀虫剂，在第二次世界大战后一段时间内，大量应用于农业和卫生保健，起过很大的作用，瑞士化学家保罗·赫尔曼·穆勒Müller因此获得1948年的诺贝尔医学奖。
For dozens of years, human beings have paid a heavy price for it : a large number of birds have died out ; Germ cells have been damaged ; Various chronic diseases have appeared…
几十年来，人类为此付出了沉重的代价：大量鸟类灭绝，生殖细胞受损，出现各种慢性疾病……

农药是昨天的福音，今天的灾难
