Any time a writer mentions Rachel Carson’s 1962 book Silent Spring or the subsequent U.S. ban on DDT, the loonies come out of the woodwork. They blame Carson’s book for ending the use of DDT as a mosquito-killing pesticide. And because mosquitoes transmit malaria, that supposedly makes her culpable for just about every malaria death of the past half century.
The Competitive Enterprise Institute, a libertarian think tank, devotes an entire website to the notion that “Rachel was wrong,” asserting that “millions of people around the world suffer the painful and often deadly effects of malaria because one person sounded a false alarm.” Likewise former U.S. Senator Tom Coburn has declared that “millions of people, particularly children under five, died because governments bought into Carson’s junk science claims about DDT.” The novelist Michael Crichton even had one of his fictional characters assert that “Banning DDT killed more people than Hitler.” He put the death toll at 50 million.
It’s worth considering the many errors in this argument both because malaria remains an epidemic problem in much of the developing world and also because groups like the Competitive Enterprise Institute, backed by corporate interests, have latched onto DDT as a case study for undermining all environmental regulation.
The first thing worth remembering is that it wasn’t Rachel Carson who banned DDT. It was the very Republican Nixon Administration, in 1972. Moreover, the ban applied only in the United States, and even there it made an exception for public health uses. The ban was intended to prevent the imminent extinction of ospreys, peregrine falcons, and bald eagles, our national bird, among other species; they were vulnerable because DDT caused a fatal thinning of eggshells, which collapsed under the weight of the parent incubating them. But the ban did nothing to stop Read the rest of this entry »
