The debate over food biotechnology in the United States: is a societal consensus achievable?
Unless the public comes to agree that the benefits of food biotechnology are desirable and the associated risks are acceptable, our society may fail to realize much of the potential benefits. Three historical cases of major technological innovations whose benefits and risks were the subject of heated public controversy are examined, in search of lessons that may suggest a path toward consensus in the biotechnology debate. In each of the cases--water fluoridation, nuclear power and pesticides--proponents of the technology gathered scientific evidence that they believed established that the innovations were safe. In each case, the federal government was heavily involved in oversight, safety regulation, and in the first two cases, active promotion of the technology. Supporters of the technologies employed a variety of communications strategies, ranging from massive "educational" campaigns (e.g. "Our Friend The Atom") to vituperative ad hominem attacks on leading opponents. None of these strategies succeeded in achieving broad societal acceptance of the technologies. Fluoridation today is opposed as vigorously by activist groups as it was when first introduced around 1950; it has not been universally adopted even in the U.S., and it has been rejected in most other countries. The American nuclear power industry is moribund, and the public has essentially rejected the technology. The pesticide industry is thriving, with new generations of products succeeding older more hazardous chemicals in a constant cycle. However, strong regulation has failed to prevent adverse health and ecological effects, which have been empirically associated with pesticide uses after the chemicals were dispersed in the environment. Debate over whether risks of such effects are acceptable has been heated for four decades, with scientists and the public divided.
