For instance, you cite the U.S. ban, but even that does permit use of the chemical in the event of a malaria outbreak. So I've included a few links to hopefully educate everybody. DDT is a powerful tool but the residual effects in the environment need to be controlled. The U.S. EPA is preparing to cap a deposit off DDT off the California Coast next year at great expense. Some of those links are included too, as anyone spouting off about DDT should have a decent background on the subject.
