Rachel Carson was an American marine biologist and author of the book "Silent Spring." Her book, published in 1962, spurred a grassroots campaign against the use of pesticides/herbicides (namely DDT) and aided in the development of the Environmental Protection Agency. Per the World Health Organization, malaria kills roughly 1 million people per year in Africa. According to Donald Roberts and Richard Tren (authors of "The Excellent Powder') anti-DDT groups like Greenpeace, the Environmental Defense Fund, the Sierra Club, and Rachel Carson could be held responsible. According to Roberts and Tren, "DDT detractors argue that if mosquitoes develop resistance to DDT and it no longer kills them, the chemical has no use for reducing malaria. They would be right if DDT were primarily a toxic agent, but in fact it is primarily a repellent that acts secondarily as an irritant and lastly as a toxic agent. This means it is still useful in malaria control even in the presence of resistance to toxicity. Thus, a lack of understanding of how DDT works has resulted in it not being used and lives being lost."
