The World Health Organization credits DDT with saving 50 million to 100 million lives by preventing malaria. In 1943 Venezuela had 8,171,115 cases of malaria; by 1958, after the use of DDT, the number was down to 800. India, which had over 10 million cases of malaria in 1935, had 285,962 in 1969. In Italy the number of malaria cases dropped from 411,602 in 1945 to only 37 in 1968. 
Europe and North America have not harbored malarial mosquitoes since the 1940s. In one of the most miraculous public health developments in history, Greece saw malaria cases drop from 1-2 million cases a year to close to zero, also thanks to DDT. Meanwhile, in India, malaria deaths went from nearly a million in 1945 to only a few thousand in 1960. In what is now Sri Lanka, malaria cases went from 2,800,000 in 1948, before the introduction of DDT, down to 17 in 1964 — then, tragically, back up to 2,500,000 by 1969, five years after DDT use was discontinued there.
"This is like loading up seven Boeing 747 airliners each day, then deliberately crashing them into Mt. Kilimanjaro," said Dr. Wenceslaus Kilama, Malaria Foundation International Chairman.

My own doubts came when DDT was introduced for civilian use. In Guyana, within two years it had almost eliminated malaria, but at the same time the birth rate had doubled. So my chief quarrel with DDT in hindsight is that it has greatly added to the population problem.

“Every time I meet patients, my main message is malaria is preventable and treatable but prevention and treatment require tremendous efforts and funding,” she said.

I then took notice of her bibliography and realized that it was filled with references from very unscientific sources. Also, each reference was cited separately each time it appeared in the book, thus producing an impressive array of “references” even though not many different sources were actually cited. I began to lose confidence in Rachel Carson, even though I thought that as an environmentalist I really should continue to support her.
But the scientific case against DDT was, and still is, nonexistent. Almost 60 years have passed since the malaria-spraying campaigns began--with hundreds of millions of people exposed to large concentrations of DDT--yet, according to international health scholar Amir Attaran, the scientific literature "has not even one peer-reviewed, independently replicated study linking exposure to DDT with any adverse health outcome." Indeed, in a 1956 study, human volunteers ate DDT every day for over two years with no ill effects then or since.

But malaria's mounting death toll in the decades since is finally prompting a rethink on DDT. In the footnotes of his best-selling anti-green novel State Of Fear, Michael Crichton asserted that the ban on the pesticide "has killed more people than Hitler". An article in Britain's Spectator magazine last month went further, branding the DDT ban as the worst crime of the 20th century, and blaming environmentalist extremists for the deaths of about 50 million people.
The EPA’s Mid-Atlantic region used the 50th anniversary of Carson’s “groundbreaking” book to demonstrate “how one person can make a difference, holding an event at the author’s recently renovated childhood home.

Why does Europe impede Uganda's fight against malaria? The standard answer starts with "Silent Spring," the book that helped launch the environmental movement in the 1960s and that painted a scary picture of DDT's potential impact on the food chain. But this is only half right. The book's overblown claims led to the banning of DDT in the United States in 1972 and its disappearance from aid-funded programs thereafter. But "Silent Spring" was really about the dangers of large-scale agricultural use of DDT, not the limited spraying of houses. Today mainstream environmental groups concede that in the context of malarial countries, the certain health benefits of anti-malarial spraying may outweigh the speculative environmental risks.

Yet DDT, the very insecticide that eradicated malaria in developed nations, has been essentially deactivated as a malaria-control tool today. The paradox is that sprayed in tiny quantities inside houses -- the only way anyone proposes to use it today -- DDT is most likely not harmful to people or the environment. Certainly, the possible harm from DDT is vastly outweighed by its ability to save children's lives.

To bolster her case for the dangers of DDT, Carson improperly cited cases of acute exposures to the chemical as proof of its cancer-causing ability. For example, she told the story of a woman who sprayed DDT for spiders in her basement and died a month later of leukemia. In another case, a man sprayed his office for cockroaches and a few days later was diagnosed with aplastic anemia. Today cancer specialists would dismiss out of hand the implied claims that these patients' cancers could be traced to such specific pesticide exposures.

Published in 1962, Silent Spring used manipulated data and wildly exaggerated claims (sound familiar?) to push for a worldwide ban on the pesticide known as DDT – which is, to this day, the most effective weapon against malarial mosquitoes. The Environmental Protection Agency held extensive hearings after the uproar produced by this book… and these hearings concluded that DDT should not be banned. A few months after the hearings ended, EPA administrator William Ruckleshaus over-ruled his own agency and banned DDT anyway, in what he later admitted was a “political” decision.

The Environmental Protection Agency (EPA) used its annual “pollution prevention” week to praise the late environmentalist Rachel Carson, whose book “Silent Spring” served as the impetus for banning DDT, a pesticide that virtually eradicated malaria in Europe.
