Which is an American marine biologist who campaigned against use of pesticides?

Rachel Louise Carson was an American marine biologist, author, and conservationist whose influential book Silent Spring (1962) and other writings are credited with advancing the global environmental movement.

Carson had become interested in the danger of pesticides while still associated with the Fish and Wildlife Service. Her concern was accelerated with the introduction of DDT in 1945. Although she had left the Service to work on Silent Spring, her marine studies while there had provided her with early documentation on the effects of DDT on marine life. Since abnormalities always show up first in fish and wildlife, biologists were the first to see the effects of impending danger to the overall environment.

Carson had long been aware of the dangers of chemical pesticides but was also aware of the controversy within the agricultural community, which needed such pesticides to increase crop production. She had long hoped someone else would publish an expose’ on DDT but realized finally that only she had the background as well as the economic freedom to do it. She made the decision to produce Silent Spring after years of research across the United States and Europe with the help of Shirley Briggs, a former Fish and Wildlife Service artist who had become editor of an Audubon Naturalist Society magazine called Atlantic Naturalist. Clarence Cottam, another former Fish and Wildlife Service employee, also provided Carson with support and documentation on DDT research conducted but not generally known.
