I'm surprised to learn that DDT is still been using used so widely.
While the environmental impact is probably greatly exagerated, DDT has one big problem in that it is very persistent. Mother Nature does not break this chemical down.
Even today, after DDT was banned in the US in the 1970s, it is still the most common pesticide found on vegetables in grocery stores.
Malaria, mosquitos and insects are huge problems that we should solve. But we should use other insecticides instead of DDT.
As a college student in Appalachia in the 50's I witnessed the reverence in which rural people held DDT. "Ain't no flies on Jesus, 'cause He's sprayed with DDT" was a popular radio tune. Mountain people would eat DDT and feed it to their children to kill parasites such as intestinal worms. The plague of mosquitoes was all but eradicated.
The environmental movement in the 60's was flexing its muscles by opposing DDT. It did not matter that DDT was then and remains today the greatest blessing to the health of poor people. They proved that they have the clout to destroy the most beneficial resources available to mankind.
Anti-humanity crusaders have always opposed all technologies that benefit humans. Their terrorist screeds in support of the environment are nothing more than an immoral oposition to free enterprise and property rights.
