The DDT/egg shell link has been debunked more times that the flat Earth theory. Please don't try to breath new life into that old propaganda. By eradicating harmful insects, the wide spread use of DDT in the third world over a span of three decades probably saved more human lives than all the medicine ever practiced.
BTW mosquitoes bite eagles too.
Bad science or not; the old propaganda WORKED!
THIS is what I'm trying to illustrate!
We have MULTITUDES of laws that are based on BAD science.
There is something in the 'news'; I hear; about a thing called HUMAN CAUSED Global Warming.
