Answer» http://www.rachelcarson.org/Silent Spring is an environmental science book written by Rachel Carson and PUBLISHED by Houghton Mifflin on September 27, 1962.[1] The book documented the detrimental effects on the environment—particularly on birds—of the indiscriminate use of pesticides. Carson accused the chemical industry of spreading disinformation and public officials of accepting industry claims unquestioningly. - From Wikipedia, the free encyclopedia Today Google marks her 70th birthday. Here books on on Amazon.http://www.forbes.com/sites/henrymiller/2012/09/05/rachel-carsons-deadly-fantasies/ Quote Carson’s proselytizing and advocacy raised substantial anxiety about DDT and led to bans in most of the world and to restrictions on other chemical pesticides. But the fears she raised were based on gross misrepresentations and scholarship so atrocious that, if Carson were an academic, she would be guilty of egregious academic misconduct. Her observations about DDT have been condemned by many scientists. In the words of Professor Robert H. White-Stevens, an agriculturist and biology professor at Rutgers University, “If man were to follow the teachings of Miss Carson, we would return to the Dark Ages, and the insects and diseases and vermin would once again inherit the earth.”BC_Programmer, Very true. Her logic was not academic. All who want to protest can sniff a can of DDT. Google search 'DDT is good for me' https://www.youtube.com/watch?v=dhkRXPd2AdA I don't even...Yeah. Overt half of the people reading this are under 40 years of age and haver no idea what went on 60 years ago. Really. Back then there were magazine articles telling peoplk to wash the heads of lice-infected children using DDT. A young toady in my doctor's office today want not even sure of want DDT was or is. DDT - A Brief History and Status Quote Development of DDTQuote and link are from the US EPA. Quote Rachel Carson's book Silent Spring in 1962 stimulated widespread public concern over the dangers of improper pesticide use and the need for better pesticide controls. Yeah. Right. All it ended up doing was promoting the use of other Pesticides that don't last nearly as long and need to be re-applied more frequently and are no less dangerous to animals or the environment, sometimes even more so. It successfully condemned effectively any and all chemical insecticides and rejected the firmly established principle that products with known but small risks can offset far larger risks and provide a net safety benefit. Quote Carson’s disingenuous proselytizing spurred public pressure to ban DDT in many countries, with disastrous consequences: a lack of effective control of mosquitoes that carry malaria and other diseases. Malaria imposes huge costs on individuals, families and governments. It inflicts a crushing economic burden on malaria-endemic countries and impedes their economic growth. A study by the Harvard University Center for International Development estimated that a high incidence of malaria reduces economic growth by 1.3 percentage points each year. Compounded over the four decades since the first bans of DDT, that lost growth has made some of the world’s poorest countries an astonishing 40 percent poorer than had there been more effective mosquito control. Again, you are right. She did what she did. Overall, she is now considered the start of the modern environmental movement. This has been debated many times in the academic community and in scientific papers. A large body of works refute her ideas. Others contend that if she had been more moderate in her assertions, few people would have even notice. The facts are that widespread use of DDT has had impact on some wildlife. That leads us to the issue of either save a bird or feed a hungry child. Here is a list. Quote Literature Cited:But if you hate birds, none of the above matters. Malaria is still a big issue in much of the world. Should DDT Be Used to Combat Malaria? Quote From Scientific American. It went on to add: Quote "Based on recent studies, we conclude that humans are exposed to DDT and DDE, that indoor residual spraying can result in substantial exposure and that DDT may pose a risk for human populations," the scientists wrote in their consensus statement, published online today in the journal Environmental Health Perspectives.That article was published five years ago. Of course the book by Carson was not about Malaria. It was about the possible harmful effects that DDT might have. Later some of here assertions were verified. As for malaria control, here is recent article that represent some current ideas and practices. Researchers test new ways of controlling malaria Sad to say, the site will not let me finish the article. That shows how much they care. Quote from: Geek-9pm on May 28, 2014, 12:13:55 AM Again, you are right. She did what she did. Overall, she is now considered the start of the modern environmental movement.And whether that's a good thing in some sense is another question altogether. The fact that such a movement is based on a large foundation of lies, fabrications and poor logic is hardly a good thing. Quote Others contend that if she had been more moderate in her assertions, few people would have even notice.In other words what they are saying is, "She had to make up lie about how dangerous things are for people to think she was saying they were dangerous". Quote The facts are that widespread use of DDT has had impact on some wildlife. That leads us to the issue of either save a bird or feed a hungry child.How is that ever an issue? What kind of sick twisted morality would somebody need to have where that is actually any form of dilemma? Quote It says: "The pesticide accumulates in body tissues, particularly *censored* milk, and lingers in the environment for decades." I can't seem to find the source research for this claim. I do, however, find it suspicious that it is mentioned to have this effect in Rachel's Book. There is no way she did any particularly scientific study on it, if the "source" of later information is that book it should be re-evaluated I think. Of course DDT is poison, but the poison is in the dose here. DDT does stick around longer but this also means it can be used with a more controlled application. The problem back then was using it for so many things, and in such liberal amounts. Smaller amounts are non-toxic- this cannot be said of the larger and more frequently applied pesticides that have come to replace DDT. In many ways the alternatives are worse than the chemical thy are intended to replace. Quote Of course the book by Carson was not about Malaria. It was about the possible harmful effects that DDT might have. Later some of here assertions were verified. I actually am not able to find that verification. The articles that state the same things do not source any research papers. It's possible some of the repetitions of the same assertions might actually just be repetitions of that information, on the assumption that the book was scientifically sound. I think we can agree if it is indeed the case that these verifications are just folks citing her without any original research that they aren't really acceptable. Primarily I'm not saying we should use DDT, but rather that the alternatives are often worse, and so we should really re-evaluate the stigma we've associated with DDT and whether in the long term we receive a net gain. particularly considering DDT practically went from being unregulated and used in so many things to suddenly being banned and used in nearly nothing. Obviously large amounts of a poison that lasts a long time is a bad idea. But smaller, more measured applications could easily defy reaching toxic levels, even over a longer timespan. Choosing alternatives simply because they don't last as long often ignores what other possible harmful effects they might have. And basing an entire movement on assertions and emotionally charged, non-scientific garbage is being a poet, not a scientist.BC, I have had enough of your misrepresentations. begin sarcasm DDT is never safe in any amount. Do a "scientific test." Find a willing victim that you do not like much, dare him to drink a cup of DDT at 5% and you drink a cup of alcohol at 50%. Then both of you go t o the nearest ER and tell them what you did. end sarcasm . This post thread is about Rachel Carson, not about DDT. Rachel Louise Carson (May 27, 1907 – April 14, 1964 Here is more about here early life. http://womenshistory.about.com/od/carsonrachel/p/rachel_carson.htm Rachel Carson was born and grew up on a farm in Pennsylvania. She dreamed of becoming a writer, and had her first story published in St. Nicholas when she was 10. She attended high school in Parnassas, Pennsylvania. Carson enrolled at the Pennsylvania College for Women (which later became Chatham College). She changed her major from English after taking a required biology course. She went on to complete an M.A. at Johns Hopkins University. Early Career: During summers, Carson worked at Woods Hole Marine Biological Laboratory in Massachusetts, and taught at the University of Maryland and Johns Hopkins. In 1936, she took a job as a writer with the US Bureau of Fisheries (which later became the US Fish and Wildlife Service). Over the years she was promoted to staff biologist, and, in 1949, chief editor. First Book: Rachel Carson's father died in 1935, and she supported and lived with her mother from that time. In 1937 her sister died, and the sister's two daughters moved in with Rachel and her mother. Carson began writing magazine pieces about science to supplement her income. In 1941, she adapted one of those articles into a book, Under the Seawind, in which she tried to communicate the beauty and wonder of the oceans. First Bestseller: After the war ended, Carson had access to formerly classified scientific data about the oceans, and she worked for several years on another book. When The Sea Around Us was published in 1951, it became a bestseller -- 86 weeks on the New York Times best-seller list, 39 weeks as the top seller. In 1952, she resigned from the Fish and Wildlife Service to focus on her writing. Another Book: In 1955, Carson published The Edge of the Sea. While successful -- 20 weeks on the best-seller list -- it did not do as well as her previous book. The Book "Silent Spring" came later. To make her point.she used hyperbole, a literary license to project an idea in a way that creates a vivid mental picture of some unlikely dreadful scenario. She already had the credentials and the background to do that. She was a good writer. And a scientist. About DDT. Here is a modern day response by some individual. Why was DDT banned. The chemicals killed insects effectively, yes, but such pesticides become more and more concentrated as they travel up the food chain. When birds like the peregrine falcon ate several different contaminated prey animals. they suddenly had huge concentrations of DDT in their body. Consequentially, the chemicals damaged their eggs so that the shells were too thin to protect the chicks, and the eggs would easily break at the slightest touch. The impact on peregrine falcons and many other animals led to the BANNING of the pesticide. There are many sources about why DDT was banned. Caron's book was just the start of an avalanche of option against the use of synthetic interstices. It was was not a lie. It was a warming given in a literally style that galvanizes ideas. It was not written as a scientific document, but she did have the training and education do so if she wished. The reason now given for the used of synthetic incidences is that it is cheap in terms of dollars. It is effective to build armies and destroy nations.
