E Crop Chemophobia N T I “Crop Chemophobia offers a science-based consideration of the impact of agricultural technol - N ogy and highlights the need to give more thought to the principles guiding the regulation of E food production. This is more than an academic debate; it could save lives.” —Mike Johanns , U.S. senator for the state of Nebraska and former secretary of the U.S. Department of Agriculture “Crop Chemophobia should be required reading for policymakers. Our greatest challenge in the next forty years will be to feed billions more people on our planet with the same land resources we now use. As this important book demonstrates, we need to have science-based discussions about how to accomplish this. In the decades ahead, the greatest risk of all may be blind adherence to the precautionary principle.” Crop Chemophobia —Bob Stallman , president, American Farm Bureau Federation C r “By placing science above scaremongering, this book should stimulate a more informed and o balanced debate on the importance of pesticides in meeting the challenges posed by popula - WILL PRECAUTION KILL p tion growth and a changing climate.” —Ian Denholm , Rothamsted Research, United Kingdom C h THE GREEN REVOLUTION? “Many consumers today rely on sensationalized media reports to form their opinions on food e production. Crop Chemophobia does an excellent job of going beyond the emotional debate m over the use of crop inputs. Those concerned with a growing world population and food inse - o curity should look closely at the consequences of removing a vital tool of food production.” p —Mike Adams , host, AgriTalk: The Voice of Rural America h o “Timely and important, this book is a call to action. We cannot afford to allow a narrow, b technology-averse agenda to saddle our global food-production system with constraints that i are costly and scientifically unwarranted—not when we face the challenge of doubling food a production in the next four decades to meet expected demand.” —W.

But what does that mean in practice? Every action indeed does lead to a reaction. This complex world is interlinked, and well-meaning initiatives are often twisted by unintended consequences. When it comes to public policy, prudence is important. Risks need to be examined in the light of not only rewards but also the likelihood of gener- ating new, unforeseen risks. Sometimes the balance between saving the earth and saving humans can be lost. This is a book about understanding and preserving that balance. If the loudest voices in the environmental movement are to be believed, we are on the edge of ecological Armageddon because of the threat of chemical contamination posed by modern agricultural farming. “Name a vegetable, and I’ll tell you how dangerous it is,” says Brian Hill, senior scientist for the Pesticide Action Network (PAN), the advocacy group lead- ing the campaign to ban many agricultural chemicals. I name broccoli, my daughter’s favorite vegetable. His voice turns grave. “The United States Department of Agriculture tested 671 samples in 2007,” he says. “Forty different residues showed up. Five are known or possible carcinogens; nineteen are suspected hormone disrupters; three can cause develop- mental or reproductive problems; nine are considered neurotoxins.” 1 CropChemophobia 11/23/10 11:26 AM Page 2 2 CROP CHEMOPHOBIA According to Hill, 1,100 pesticides can be found in the U.S.
