Saving African children is easy. We don’t need to build large aid programs or fund major health initiatives, let alone develop Third-World infrastructure or think about larger issues of fairness. No, to save African lives from malaria, we just need to put our wallets away and work to stop the evil environmentalists.

Unfortunately, it’s not so easy.

For one thing, there is no global DDT ban. DDT is indeed banned in the U.S., but malaria isn’t exactly a pressing issue here. If it ever were, the ban contains an exception for matters of public health. Meanwhile, it’s perfectly legal and indeed, used in many other countries: 10 out of the 17 African nations that currently conduct indoor spraying use DDT (New York Times, 9/16/06).

DDT use has decreased enormously, but not because of a ban. The real reason is simple, although not one conservatives are particularly fond of: evolution. Mosquito populations rapidly develop resistance to DDT, creating enzymes to detoxify it, modifying their nervous systems to avoid its effects, and avoiding areas where DDT is sprayed and recent research finds that that resistance continues to spread even after DDT spraying has stopped, lowering the effectiveness not only of DDT but also other pesticides (Current Biology, 8/9/05).

Identification of and reflection on a meme that is propagated through mainstream media: DDT could save Africa from Malaria, if not for those pesky environmentalists.

As this link points out, Michael Crichton (the author and near-doctor who addressed the US Congress on the topic of environmentalism) mentions the “DDT meme” in a recent work, but notably, Crichton’s use is not rigorous.
