Regarding "After Four Seasons of High Growth, Transgenic Crops Are Now Wilting" (Opinion, Feb. 22) by Brian Halweil: Mr. Halweils argument is so full of weeds as to be worthless.
He claims that plantings of genetically engineered crops may be down as much as 25 percent from last year because of farmers fears that their crops will not be accepted. Never mind that those fears were created in the first place by environmental groups such as Mr. Halweils Worldwatch Institute. Moreover, the Worldwatch data have been outdated by two major recent developments.
If the "precautionary principle" were in effect a century ago, wed all still be "driving" these.
In the years during which Americans have eaten biotech crops, about 200,000 of them have been killed by motor vehicles, but not one from genetically modified food. Yet cars should remain legal, while biotech food is yanked from store shelves. The precautionary principle is nothing short of a prescriptionto halt progress in its tracks, which indeed is its main appeal to supporters.
