Ever since local author Rachel Carson attacked the use of DDT 40 years ago in her book "Silent Spring," the pesticide has come to symbolize the devastation humans can cause to the environment.
But now, many health experts and activists around the world say DDT should be reintroduced to fight one of the deadliest diseases on the planet -- malaria.

From Dixie Lee Ray's Trashing the Planet an excellent antidote to Rachel Carson's Silent Spring:
"In the case of thin egg shells, it is a phenomenon that predates use of DDT. It has been known for decades. There are many causes: diets low in calcium or Vitamin D, fright, high nocturnal temperatures, various toxic substances, and diseases such as Newcastle's disease. Experiments designed to show a toxic effect from eating DDT failed, even though the experimenters fed their birds (pheasant and quail) from 6,000 to 20,000 times more DDT than the 0.3 parts per million residue of DDT found in food."
Also, "DDT is not a carcinogen. Laboratory studies have reported liver deformations in mice, but not in any other experimental animal (including rats). This is the basis for the charge that DDT is "cancer-causing." The doses, given by injection, required to cause the deformation of a mouse's liver were about 100,000 times higher than any possible ingestion from DDT residues in food."
"These data and much more were presented at the 1971 hearing and the recommendation, after considering 300 technical documents and the testimony of 150 scientists, was that a total ban on DDT was not desirable, based on the scientific evidence. The hearing examiner declared in his final decision: 'There is a present need for the continued use of DDT for the essential uses defined in this case.'
That was in April 1972. Nevertheless, two months later, on June 14, 1972, William Ruckelshaus, EPA administrator, banned all uses of DDT unless an essential public purpose could be proved. Whey did he do it? Two years earlier, Ruckelshaus had stated his support of DDT, citing its 'amazing and exemplary record of safe use.' Was he trying to curry favor with the environmental activist organizations? (When he left the EPA, he signed membership solicitation letters for the Environmental Defense Fund, the organization that led the fight against DDT.) Or was he trying to demonstrate muscle and establish the power of the EPA?
Years later, Ruckelshaus admitted that 'decisions by the government involving the use of toxic substances are political...[and] the ultimate judgment remains political....[In] the case of pesticides, the power to make this judgment has been delegated to the Administrator of EPA."
