Edwards was a prominent supporter of the use of
DDT and critic of
Rachel Carson. He claimed that bans of DDT were not based on good science, and accused environmentalists of politicizing issues regarding pesticides. He was active as a member of, or consultant for, a wide range of lobby groups opposed to environmental regulation, including the
American Council on Science and Health. According to Edwards, he was also active as a member of several environmental groups, such as the
Sierra Club (which published one of his books), and the
Audubon Society. Edwards was a fellow of the
California Academy of Sciences. He published his ideas in
21st Century Science and Technology, a publication of the
Lyndon LaRouche Movement. Edwards last work, titled
DDT: A Case Study in Scientific Fraud was published in 2004 after his death in the fringe partizan
Journal of American Physicians and Surgeons, in which he makes the impassioned plea "The ban on DDT, founded on erroneous or fraudulent reports and imposed by one powerful bureaucrat, has caused millions of deaths, while sapping the strength and productivity of countless human beings in underdeveloped countries. It is time for an honest appraisal and for immediate deployment of the best currently available means to control insect-borne diseases. This means DDT." In 1971 he gave testimony before the Congressional
House Committee on Agriculture which was widely cited and circulated, despite having published no scientific papers on DDT or birds at the time. In the 1970s Edwards was involved in a libel suit against the
New York Times and the
National Audubon Society. In April 1972,
Robert Arbib Jr., the editor of the Society's
American Birds journal, wrote in an editorial that representatives of pesticide industries and "paid 'scientist-spokesmen were misleadingly using data from
Christmas Bird Count to claim that bird populations were increasing despite the usage of DDT, and that apparent increases in songbirds were the result of more birdwatchers rather than more birds. Arbib did not name any individuals in his article, but when contacted by the
Times, said they included Edwards,
Thomas H. Jukes, and Robert H. White-Stevens, among others. Edwards, Jukes, and White-Stevens sued the
Times for libel, and in 1976 were awarded $61,000, a ruling that was overturned the following year by a Federal appeals court citing freedom of the press to report on public figures. ==Mountaineering==
