In addition to the unknown side effects of GMO's that might take us a few generations to learn about, the scarier thing for me is the risk of GMO's going into the wild and becoming an invasive species that wipes out native crops and habitats. By the time we know if GMO's are good for us and the environment or not, it may be too late to go back to conventional crops. Agree completely on the pesticides comment though. Biggest innovation in crop yield seems to be hydroponics and vertical growing. Fraction of the water use and don't need to worry about soil.
