Cottam hired and worked with Carson at the U.S. Fish & Wildlife Service and remains a close friend. He wrote about the deleterious effects of pesticides as early as 1946. Carson has cited Cottam's work in Chap. 10 of Silent Spring. She consulted him in 1959 about the nature of her writing project. In 1961 Cottam was awarded the Audubon Medal for his "achievement in the field of conservation and environmental protection." He also recently served on the NRC committee on Pest Control and Wildlife Relationships.
Be sure to review Chaps. 1-2,7-10,15 in Silent Spring. You should be able to comment on Carson's credibility, harm to non-target species, safety, and indiscriminate use. Be familiar with the controversial fire ant eradication program. Consider a response to George Decker? Take special note of your 1946 co-authored article on DDT and your long-term relationship with Miss Carson.
