Perceived Risks Incurred Along With Genetic Engineering's Alluring Benefits New approaches to the practice of medicine and to food production have arrived on the technolo-gical scene as a consequence of the knowledge gained through modern genome sequencing. Now Scientists and genetic engineers can modify and manipulate the fundamental genetic code of cer-tain crops and animals to benefit mankind. Although the stated goals of genetic engineering and genetic modification are noble, these activities are not without associated risks and drawbacks, which apparently have received much less attention. The discussion below is an attempt to reme-dy that oversight by discussing both aspects in one gulp in a form that is easy to understand, without hype, with the venom removed and the invective wording toned down (from how it was originally stated elsewhere in many cases). We eschew being extreme in portraying either view; otherwise, adversaries would dismiss it out-of-hand as not being worthy to even consider further. In compiling the list of risks (and benefits) here below, we rely only on information and facts provided by internationally recognized scientific journals, nationally recognized newspapers, and three of the Public Broadcasting System's (PBS) NOVA series [1]-[3]. Each of these particular sources is well known for thoroughly crosschecking its supporting facts and, moreover, is avail-able from most U.S. public libraries for further confirmation. We specifically avoided visiting or viewing Web sites, pro or con (such as those of the USDA, FDA, EPA, The Foundation for Eco-nomic Trends, Friends of the Earth, International Green Peace, or the Earth Liberation Front) because information posted on the Web, in general, is notorious for being self-serving (by dis-seminating biases interspersed with truth), ephemeral (since it can vanish), and time-varying. Our aim here is not to convert or dissuade any existing views away from the current U.S. policy of encouraging progress in genetic engineering/genetic modification because the apparent con-sensus is that it is important for the long-term welfare of the U.S. and the world, both scientific-cally and economically, to continue on this course. The objective here is merely to delineate the benefits (as perceived by its advocates) and the drawbacks (as perceived by its opponents) of Genetically Modified Organisms (GMO), all in one place. The worries of the GMO critics appear to all pertain, at a high level, to one or more of the following four questions:
