One of the stranger efforts of the political right over the last decade has been the effort to paint Rachel Carson as a mass murderer, on the basis of bogus claims conflating the US ban on non-public health uses of DDT with a non-existent ban on the use of DDT as an antimalarial. Starting from the lunatic fringe of the LaRouche movement and promoted primarily by current and retired hacks for the tobacco industry, this claim has become received wisdom throughout the US Republican party and its received offshoots. Although this nonsense has been comprehensively demolished by bloggers, most notably Tim Lambert, article-length refutations are desperately needed. Now Aaron Swartz has a piece published in Extra!. It’s great to see this but, as the global warming debate has shown, one refutation is never enough in resisting the Republican War on Science.
