For millions of maturing baby boomers, Carson turned cautionary eyes to another post-war product that was similarly coming of age—the organochlorine pesticide DDT. The intent of this chapter is to present enough of the several aspects of the DDT story to establish its relationship to and its role in the practice and transformation of agriculture. The history, synthesis, environmental, human, its agricultural effects, and the crucial role and effects of Rachel Carson’s 1962 book, Silent Spring, are important parts of the DDT story. Its undeniable benefit of improved insect control, contribution to the development of pesticide chemical industry, and its real and imagined harm to the environment, humans, and other creatures transformed agricultural insect control, American agriculture, and societal attitudes to agriculture’s chemical technology.
The public and scientific demand for answers to the questions that before DDT had not been asked is an important part of its legacy. Its relatives, and subsequent pesticides from many chemical families, contributed to the transformation of agriculture from what was regarded as a beneficial enterprise that produced the food we need to a suspect enterprise that externalized many of its costs.
