In the early 1970s, the formative years of the science of laboratory genetic engineering, the first concerns were not raised by activists, but by scientists. They said that we did not have a grasp on the effects of GMOs on nature, and on humans. In 1981, James Watson, the co-discoverer of the DNA double helix, said, “Might some of the new genetic combinations that we would create in the test-tube rise up like the genie from Aladdin’s lamp and multiply without control, eventually replacing preexisting plants and animals...?" Such scientific concerns were not very different from the fears surrounding nuclear technology, or the more recent fears about radiation from cellphone towers, and the colliders where high-energy particles are smashed to see what comes out of the collision. Eventually, the scientific community began to accept that there was reasonable evidence to suggest GMOs were safe for humans and for earth’s natural vegetation, and everything that depended on it. Watson himself was assured. “My position is that I don’t read recombinant DNA as a major or plausible pubic health hazard...." But activists stayed with the fear because they are in the business of fear.
