When the Environmental Protection Agency banned DDT late in 1972, environmentalists hailed the decision. Indeed, the DDT ban became a symbol of the power of environmental activism in America. Since the ban, several species that were decimated by the effects of DDT have significantly recovered, including bald eagles, peregrines, ospreys, and brown pelicans. Yet a careful reading of Rachel Carson's reveals DDT to be but one of hundreds of chemicals in thousands of formulations. Carson called for a reduction in the use of all chemical insecticides. Carson's recommendations notwithstanding, policymakers focused on DDT and other chlorinated hydrocarbons, culminating in the DDT ban, passage of the Federal Environmental Pesticide Control Act of 1972, and subsequent bans on aldrin and dieldrin. Similarly, the history of pesticides has focused inordinately on DDT, providing a myopic image of the ongoing challenges of pesticides in agricultural practice and ongoing environmental protection efforts in the modern world. "Pesticides and the perils of synecdoche" argues that focusing on DDT oversimplified the environmental risks of chemical insecticides and narrowed the parameters of the debate, and in the process both policy and subsequent histories neglected the highly toxic organophosphate insecticides, which dominated agriculture in the United States and the world after the DDT ban, with unintended consequences for farmworkers and wildlife.
1972年末美国环境保护局禁止使用滴滴涕(DDT)时,环保主义者对这一决定表示欢迎。事实上,滴滴涕禁令成为了美国环境激进主义力量的象征。自禁令实施以来,几种因滴滴涕影响而数量锐减的物种已大幅恢复,包括白头鹰、游隼、鹗和褐鹈鹕。然而,仔细研读蕾切尔·卡森的著作会发现,滴滴涕只是数千种配方中的数百种化学物质之一。卡森呼吁减少所有化学杀虫剂的使用。尽管有卡森的建议,但政策制定者们将重点放在了滴滴涕和其他氯代烃上,最终导致了滴滴涕禁令、1972年《联邦环境农药控制法》的通过以及随后对艾氏剂和狄氏剂的禁令。同样,农药的历史过度聚焦于滴滴涕,对农业实践中农药持续存在的挑战以及现代世界正在进行的环境保护努力呈现出一种短视的画面。《农药与提喻的危险》一文认为,关注滴滴涕简化了化学杀虫剂的环境风险,缩小了辩论的范围,在此过程中,政策及后续的历史都忽视了剧毒的有机磷杀虫剂,在滴滴涕禁令之后,这类杀虫剂在美国乃至全世界的农业中占据主导地位,给农场工人和野生动物带来了意想不到的后果。
