On the one hand, DDT does a lot of second hand damage in the environment but I do see the original point that was being made about it, which I assume was a reference to the fact that people are dying of malaria that could be prevented by the use of DDT. DDT however is not a long term solution because, if we can all remember, insects in North America were virtually immune to it by the time it was banned.

And to continue the off topicness going on, last week there were news items that the breakdown byproduct of DDT, DDA, which allegedly acts as a fake hormone in the human body, is becoming suspect in the western obesity epidemic. And there they were blaming McDonalds! (I hasten to add that I'm jokingly referring to the notorious chain of fast food restaurants).
