I believe the link between breast cancer and DDT is fairly tenuous as it now stands; the others have more substantial evidence although they're not huge effects.
Feel free to post any substantial criticisms of the links, but remember that science is hard and in epidemiology a perfect, unassailable study is impossible to attain. That works both ways - nobody's posted any evidence that widespread use of DDT would have saved millions of lives here either which certainly isn't something you can take for granted, as the evidence is that it wouldn't. It just increases resistance and makes targeted use (which can be effective and wasn't banned) ineffective.
It's been a while since I read much about the topic, but I had a read of some of the websites blaming Rachel Carson's book for tens of millions of deaths, and frankly wasn't impressed. The idea that you can 'prove' safety by exposing people to something for a few years is showbiz, not science.
