> GMO is harmful On the basis of the article that you linked to, I think it would be more accurate to say that "currently available GMO food is not thought to be harmful to humans." There is nothing inherent in genetic modification that prevents if from being used to create food that is harmful when consumed by people (or animals) - whether due to toxicity or negative dietary effects. There probably isn't much incentive to do the former (except maybe as a weapon of war or terrorism), but engineering unhealthy but addictive foods isn't hard to imagine. Similarly, theres nothing in the technology that prevents it from being used to develop plants or animals that cause harm to their environment - for example by runaway reproduction, excessive use of resources like water, affecting species equilibria, etc. I personally wouldn't be worried about eating a GMO foodstuff, but I'm extremely unhappy about the environmental impact of ideas like terminator seeds or engineered pesticide resistance that leads to over-use of pesticides, and I wouldn't call them "safe".
