DDT is a dangerous chemical that ends up and biomagnifies in the environment. DDT and its cousin DDE are not acutely toxic to humans but they are passed from human to human via mother's milk and they are stored in fatty tissue in babies. It is foolish to assume that a ban on DDT is responsible for the death of 3 billion people due to malaria. DDT was not banned in many places Africa and Asia and it is continued to be used but with less effect because mosquitoes have acquired immunity to DDT. The eradication of malaria in the US and Europe was due to improved standards of living, better protection, removal of habitat sources for mosquitoes and better medical treatment. In the US, malaria was in many places eradicated before DDT arrived on the scene. The eradication of malaria is tied to economic conditions and improvement of living standards and not to the spraying of DDT.
