Zombies never die, and that’s even more true of zombie ideas. One of the most thoroughly killed zombies, the myth that Rachel Carson is responsible for millions of deaths from DDT, has recently re-emerged from the rightwing nethersphere where it has continued to circulate despite repeated refutation. That wouldn’t be worth yet another long post except for the source: Dr Paul Offit, a prominent pediatrician and leading pro-vaccination campaigner, writing in the Daily Beast. Offit’s revival of the DDT ban myth is a double disaster for science and public health.
