Roger Bate of Africa Fighting Malaria has responded to my article with Tim Lambert defending Rachel Carson against the claim that she promoted a ban on DDT that has killed millions of people. Not surprisingly, he doesn’t like the article, and says we’ve overstated the extent of his work for the tobacco industry, though he doesn’t deny working for them. Since we’ve already debated that point with a commenter in the previous thread (the evidence is here with more detail here), I won’t go over it again, except to agree that we could have said more about the extent to which Bate has moved away from his initial position and his links with the tobacco lobby.
Instead I want to start with a focus on the areas of agreement which turn out to be surprisingly large. Most notably, Bate states
there are many ill-informed arguments for the use of DDT to be found, especially online. I may not have done enough in the early years of this decade to respond to those excesses, and may even occasionally indulged in them myself, but for many years I have tried to be logical.
He makes no attempt to defend Steven Milloy, the main target of our article, or his many imitators in the media and blogosphere (some Australian examples here and here.)
Bate also endorses Carson’s warnings on the dangers of overuse of agrochemicals, of which DDT was a major component, and the ban on agricultural use of DDT. He doesn’t challenge any of the points made in the article about the failure of the attempt to eradicate malaria using DDT, or about the role of resistance.
In fact, the only factual error he claims (leaving aside disputes about AFM and its funding) actually supports our case. The article stated that the public health exemption from the US ban on DDT had apparently never been used, and the word “apparently” was dropped in editing. Bate points out that DDT has been used in the US on a number of occasions, so that even the fallback claim of a “de facto” ban, pushed by many blogospheric promoters of the DDT ban story, is not true.
Finally, Bate’s article largely confirms our point that the origins of stories about the mythical DDT ban lie in the leadup to the Stockholm convention, during which, as we noted, some environmental groups pushed for the setting of a target date for DDT to be phased out, but ultimately agreed to preserve the DDT exemption. The link so commonly drawn to the US ban in 1972 is entirely spurious.
