From William Souder’s article in Slate:
The Competitive Enterprise Institute, a limited-government, free-enterprise think tank, maintains the website rachelwaswrong.org, which details Carson’s complicity in the continuing plague of malaria.[…]
The Competitive Enterprise Institute—to its credit—acknowledges that Carson did not call for the banning of pesticides in Silent Spring. But they claim Carson’s caveat about their value in fighting disease was so overwhelmed by her general disapproval of their use that “negative publicity” around Silent Spring halted the use of DDT against malaria, notably in sub-Saharan Africa, where some 90 percent of the world’s malaria cases occur.
