DDT Doesn't Taste Good, December 17, 2002
Rachel Carson sent tremors through American society with the publication of her 1962 book "Silent Spring." Carson, a marine biologist who died two years after publication of the book, wrote "Silent Spring" when she received a letter from a concerned citizen lamenting the mass death of birds after a DDT spraying. Carson continues to serve as a touchstone for both mainline and radical environmental groups, from the Sierra Club to Earth First!. It is not difficult to see why; Carson's call for active involvement in our environment is still an absolute necessity today as the industrial system continues its rapid march across the landscape. If we do not want our children born with gills and fins, keeping Carson in mind is important.Carson's analysis of DDT and other synthetic chlorinated hydrocarbon pesticides resulted in a deeply ominous conclusion-pesticides destroy the environment and threaten everything within the ecological system. Carson examined the composition of pesticides, revealing that synthetic pesticides have the ability to not only kill their intended targets, but they also move right up the food chain, eventually reaching the human population. The pesticides then build up in the tissues of the body, rarely breaking down but often building in intensity through continued exposure or changing into forms that are even more toxic by interacting with other ingested chemicals. Even worse, these chemicals cause tremors, paralysis, cancer, and a host of other unpleasant ailments. Carson cites numerous stories about exposed people falling ill and dying shortly after spraying these toxic chemicals. Carson also shows the biological process these poisons take when they enter the body, when they cut off oxygen to the cells and raise the metabolic rate to unhealthy levels. Carson proves these chemicals move on to succeeding generations of offspring through mother's milk and other biological processes. Most of the book deals with the effects of chemical spraying on wildlife in the environment. Separate chapters deal with birds, insects, fish, and plant life. Needless to say, the picture painted here is not pretty. Too often, spraying chemicals in the 1950's and 1960's brought into play the full ignorance of the human race. Carson's book shows how farmers applied pounds of poisons to their land, far exceeding the recommended application levels. Spray trucks moved through neighborhoods, hosing down the community with poison while the kiddies played outside in the yard. On several occasions, planes sprayed poison on cities. This reckless disregard for life in any form ruined landscapes, created mounds of animal corpses, and gave us tasty water that can melt your teeth. What is surprising about Carson's book is that people knew all about the effects of these poisons. "Silent Spring" made a difference because it puts it all together, showing how a series of localized incidents is, in fact, a national problem. Carson also wrote her book in a style where even the densest yokels in the herd could figure out the dangers of the problem. Since I am a science idiot, I appreciated Carson's clear articulation of the problem without sacrificing the hard data behind the examples. Carson delivers a stinging rebuke to our conception of mankind as the dominant force in the universe. If humanity truly rules the roost, so to speak, why are we such idiots about sustaining the very environment that feeds us? The ignorance of man in this book is astounding. Repeatedly, we destroy and destroy again even in the face of overwhelming evidence of the damage we are causing. Local governments kept spraying even when evidence showed it was a failure. Birds literally fell out of the sky while the trucks went out for another pass through the neighborhood. Dumb, dumb, dumb! "Silent Spring" concludes with a call for sanity. Carson's answer to the insane escalation of chemical spraying is to seek out biological control methods. Many insects have natural enemies that, if introduced into a problem area, will keep down pest populations. Even localized spraying will work better than mass, indiscriminate spraying. Carson argues that biological control methods are increasingly important because insects are building up resistance to pesticides, requiring the creation of even more virulent poisons in a never-ending cycle where nobody wins. "Silent Spring" is required reading for anyone concerned about the environment. Carson's book led to significant changes in environmental law (some would say not enough change) and resulted in the outright ban of DDT. My only problem with the book is the introduction written by Al Gore, as the publisher marketed the book with that fact in mind. Gore's name seems to merit equal billing with Carson's on the cover. One must remember Al Gore is a politician and is in league with the destroyers because he needs their money to run his expensive campaigns. Carson would be appalled.

Misunderstood, June 4, 2003
Too many reviewers see only one thread of Carson's argument: that DDT and pesticides like it endanger the environment. The other thread is that DDT resistance in mosquitoes develops very quickly, and the more quickly the more it is used. Which leaves us right back where we started. Her argument is not that pesticides should not be used, but that they should be used intelligently. In this age, when antibiotic resistant bacteria are becoming a very serious problem precisely because of antibiotic overuse (and not only in hospitals, but, most egregiously, as growth enhancers for livestock), this argument should be indisputable.

Important read!!, October 9, 2003
As an entomologist I would like to clarify what I have seen in some of the prior reviews. I would also like future readers of this book to understand that it was written in 1962. It's important to understand what Rachel Carson's book was trying to do. She had to make an impact to millions of readers, and do so in layman's terms. That was a near insurmountable task, especially the way in which women in science were treated during that era.I do agree with others in that some of her statements are based on shaky evidence. However, I don't agree that see is responsible for thousands of deaths due to malaria. Diseases have existed for THOUSANDS OF YEARS, and all animals have had to deal with it, including humans. For example, humans with sickle cell anemia are immune to malaria. It is easy for someone in America to say that DDT should not be used in Africa to fight disease, because we don't have to deal with the thousands of people dying every day. Perhaps DDT can be used in more precise applications to cut down on mosquitos (which are the vectors or carriers of the disease). However, malaria and other autochthonous diseases in Africa can be dealt with by means other than DDT, and thanks to Rachel Carson, funding for research into areas such as creating transgenic mosquitos is a reality. Someday we may have the ability to eraticate malaria, and credit would undoubted have to partly go to her. The issue of the safety of DDT has been mentioned in many of these reviews, and the truth is NO ONE IS RIGHT! There has been almost no testing into the safety of DDT, so it's impossible for anyone to say that it's safe or dangerous (to humans). A famous toxicologist once said, "The poison is the dose". The big problem with DDT is that it biomagnifies and is fat soluble; in other words gets easily passed through the food chain and increases consequently in concentration while been stored in fats. So basically, that "dose" increases and increases and can more easily damage organisms. But again, not a lot of scientific research has been done in this subject, so I wouldn't say anything about DDT other than a my own hypothesis. In summary, read this book, its a little dry, overstates its point, but it changed the world's perspective on pesticides. If you want to see a good reference on insecticides look for: Pedigo, L. P. 2002. Entomology & Pest Management, 4th edition. Prentice Hall, Upper Saddle River, NJ. xxii + 742 pp.
