Steve, you conveniently ignore stuff like the Clean Air Act that has improved health and extended lifespans. You forget acid rain legislation which was hugely successful. You forget legislation that has vastly improved the water quality our rivers an lakes.

I bet you were against all those... or are you only for the stuff that has already proved successful?

"Millions have died because the DDT scam was successfully implemented. "

Just making shit up again. How does banning DDT for agricultural use kill people?

The current global warming snake oil crowd reminded me of the efforts to ban DDT. Millions have died because the DDT scam was successfully implemented.

I won't bother dispelling the rest of your distortions...but here's a sample of your ignorance.

The Stockholm Convention, ratified in 2001 and effective as of 17 May 2004, outlawed several persistent organic pollutants, and restricted the use of DDT to vector control. The Convention was signed by 98 countries and is endorsed by most environmental groups. Recognizing that a total elimination of DDT use in many malaria-prone countries is currently unfeasible because there are few affordable or effective alternatives for controlling malaria, the public health use of DDT was exempted from the ban until such alternatives are developed. Regular updates on the continued need to use DDT and on global DDT production and use is available from the Stockholm Convention. [3] Malaria Foundation International states:

Use in the 1940s and 1950s

DDT is the best-known of a number of chlorine-containing pesticides used in the 1940s and 1950s. It was used extensively during World War II by Allied troops in Europe and the Pacific as well as certain civilian populations to control the insect vectors for typhus and malaria (nearly eliminating typhus as a result). Entire cities in Italy were dusted to control the typhus carried by lice. DDT also sharply reduced the incidence of biting midges in Great Britain, and was used extensively as an agricultural insecticide after 1945.

DDT played a small role in the final elimination of malaria in Europe and North America, as malaria had already been eliminated from much of the developed world before the advent of DDT through the use of a range of public health measures and generally increasing health and living standards.[11] One CDC physician involved in the United States' DDT spraying campaign said of the effort that "we kicked a dying dog."[12] But in countries without these advances, it was critical in their eradication of the disease.

In 1955, the World Health Organization commenced a program to eradicate malaria worldwide, relying largely on DDT. Though this program was initially highly successful worldwide (reducing mortality rates from 192 per 100,000 to a low of 7 per 100,000),[13] resistance soon emerged in many insect populations as a consequence of widespread agricultural use of DDT. In many areas, early victories against malaria were partially or completely reversed, and in some cases rates of transmission even increased.[14] The program was successful in eliminating malaria only in areas with "high socio-economic status, well-organized healthcare systems, and relatively less intensive or seasonal malaria transmission".[15]

DDT was less effective in tropical regions due to the continuous life cycle of mosquitoes and poor infrastructure. It was not pursued at all in sub-Saharan Africa due to these perceived difficulties, with the result that mortality rates in the area were never reduced to the same dramatic extent, and now constitute the bulk of malarial deaths worldwide, especially following the resurgence of the disease as a result of microbe resistance to drug treatments and the spread of the deadly malarial variant caused by Plasmodium falciparum. The goal of eradication was abandoned in 1969, and attention was focused on controlling and treating the disease. Spraying programs (especially using DDT) were curtailed due to concerns over safety and environmental effects, as well as problems in administrative, managerial and financial implementation, but mostly because mosquitoes were developing resistance to DDT.[14] Efforts were shifted from spraying to the use of bednets impregnated with insecticides.[16][15]


Along with the passage of the Endangered Species Act, the US ban on DDT is cited by scientists as a major factor in the comeback of the bald eagle in the contiguous US.

So. by the time DDT was banned in the US, its effects were largely negative.
