Natalia,
People’s homes were sprayed twice a year. The WHO used 335,000 sprayers who were thus exposed heavily to DDT. No-one died as a result of DDT exposure – says the WHO. The bird death problem is a myth. The actual count was that 16 species were up, and 9 down over the years of DDT use. As I mentioned to Arthur, all the raptor counts were up. Lots of things cause eggshell thinning – including environmentalists prying around. Oh, yes, the wild animal count was up for all except mountain sheep. There is no record of anyone being killed by DDT, though one hardy soul ate and drank it for a year. Banning DDT was a con executed by environmental fanatics and nothing scientific entered into the ban. Harry ********************************** Henry George School of Social Science of Los Angeles.

This is usually cost prohibitive for people whose annual income may not exceed same, or whose monthly food allowance would have to be spent. Donations were supposed to have paid for these nets, but, as usual, administrative costs come first. What it likely means is that there is a huge surplus of nets doing no one any good, and people die needlessly. I just gave Darryl a call on this topic, having remembered a previous discussion about DDT use on this list. Darryl Beschell has, as some of you know, worked extensively with farmers and government to reduce or avoid pesticide use. His first response was that DDT use, typically applied in areas of still water where the malaria-carrying mosquito breeds, also wipes out all beneficials (predators) which would otherwise be feasting upon the vector's larvae, therefore eventually making the problem far worse. DDT also kills amphibians in the water, effects the birds and other wildlife using the ponds, and though it doesn't cause cancer, can bring about one of many mammalian health concerns such as asthma, allergies, reproductive irregularities and also interferes with calcium uptake -- hence, among many concerns -- the poor quality of bird's egg shells . If you don't eradicate the beneficials, there'll be fewer malaria carrying mosquitos. Introducing more water dwelling or visiting beneficials to these areas would be the least harmful answer. Draining still water is another less toxic solution, since DDT use would kill off life in the ponds anyway. Natalia Lawrence de Bivort wrote: I don’t think Carson pretended to be a chemical research scientist. Above all, she gave the alarm, and I think her essential thesis – that infusing the food stream and environment with industrial chemicals is a bad thing – has stood the test of time very well, e.g. cigarettes, MSG, transfats, etc. That she didn’t focus on cigarettes is not much of a criticism; that she alerted a society and its environmental scientists to pay attention to these things is high praise. No tragedy at all there. DDT is a good example of an agent that is inadequately understood. And malaria is a horrible disease. And yes, trying to rectify errors and improve our health through systemic interventions will produce unintended effects. No surprise there. But is it not better than to try and solve problems than ignoring them for fear of not always getting it right? Dandelions? Wente has got to be kidding! Dandelion salad, dandelion wine.... Does anyone know if malaria can be stopped by any means other than stopping DDT?

It was in one of Harry's postings that I first became aware of the DDT controversy and Rachel Carson's role. Arthur ---------------------------------- Comment Carson's toxic legacy; Her book Silent Spring is a case study in the tragedy of good intentions MARGARET WENTE 24 May 2007 HYPERLINK "javascript:void(0)"The Globe and Mail I was 12 when I read Rachel Carson's newly published book, Silent Spring, in 1962. Although I'd never heard the term “environmentalist,” she turned me into one. I didn't understand the complicated science in it. But I was horrified by her evocation of a natural world whose creatures were being wiped out by man-made poisons – the silent spring, where no birds sang. In school, I wrote an essay praising Silent Spring, and another one explaining why a bomb shelter wouldn't help you survive a nuclear attack. (That was an apocalyptic time, not unlike our own.) Born 100 years ago this week, Ms. Carson is still revered as the patron saint of the environmental movement. Schools, conferences and special days are named after her. Among her foremost admirers is Al Gore. “Silent Spring came as a cry in the wilderness, a deeply felt, thoroughly researched and brilliantly written argument that changed the course of history,” he wrote. Indeed it did – and not necessarily for the better. In fact, it led to one of the greatest tragedies of modern times. Thanks to Ms. Carson's all-out attack on pesticides, DDT was banned in the West. But DDT was also the most effective anti-malarial agent ever invented; before it fell into disrepute, it was credited with saving 100 million lives. When the Western nations cut off their support for DDT spraying programs in the Third World, the death toll shot back up. Today, malaria cripples local economies and kills 2.7 million people every year – mostly children under 5. In a devastating investigative piece, New York Times journalist Tina Rosenberg wrote, “Silent Spring is now killing African children because of its persistence in the public mind.” “Poor woman. She never actually said ‘Ban DDT,' ” says Amir Attaran, an expert on public-health and development policy at the University of Ottawa. “Her point was that we should use chemicals less.” But for environmental fundamentalists, Silent Spring was the ideal propaganda tool to drive home their message. And even though the World Health Organization has now reversed itself on DDT, countless environmental and cancer activists continue to cite the DDT ban as one of environmentalism's greatest “victories.” DDT's persistence in the environment did, indeed, affect certain bird species, such as eagles. But after decades of testing, there's not a shred of evidence that it causes cancer in humans, as Ms. Carson claimed. Although she was an eloquent, impassioned writer, science wasn't her strong suit. “She focused on the one environmental subject [chemicals] where you have to have the greatest scientific knowledge,” says Prof. Attaran. Silent Spring is riddled with anecdotal evidence and misleading assertions that flunk the most basic science test. “Today more American school children die of cancer than from any other cause,” she wrote, implying that pesticides were to blame. But the real reason for this alarming trend was the dramatic decline in other causes of child mortality, especially infectious diseases. At the time she wrote, the mortality rate from childhood cancer hadn't changed for decades. Curiously, she also overlooked the greatest man-made cancer agent of them all: cigarettes. Today the legacy of Silent Spring is all around us. As cities and towns rush to ban lawn sprays, you can thank Ms. Carson for the dandelions in the park. The belief that man-made agents are unnatural, and thus inherently bad – even in the most minute amounts – is now widespread. Millions of people are convinced that toxic chemicals in our food, our water, and our air are responsible for the cancer epidemic, even though no such epidemic exists. Her apocalyptic prophecies about how mankind is destroying the Earth are faithfully reproduced by extremists in the global warming crowd. Most seriously, groups like the Sierra Club continue to lobby against DDT because of the potential for “widespread misuse” – yet another example of the distressing tendency among environmentalists to sacrifice the interests of the Third World because they think they know better. Ms. Carson wasn't really the mother of environmentalism either, as her admirers like to claim. By the time she came along, the environmental movement had been going strong for decades, and the public had already embraced the importance of species conservation and the preservation of open spaces. The movement was already poised for its next – and far more problematic – wave, the assault on Big Chem. “She didn't launch that movement,” says Prof. Attaran. “She was used by it.” And she was not used well. She may have turned the sixties generation on to environmentalism. But ultimately, Silent Spring is a case study in the tragedy of good intentions.
