Blair31: you're referring to hybridization-genetic modification cannot happen in nature even with human 'help' . Learn the difference-because it makes all the difference in the world. As for testing, what has NOT been tested (and all testing has been paid for-and selectively edited-by the GMO producers) is the long-term effect on both human health and nutrition and carry-over into the environment. Some testing has shown actual DNA changes in the human gut due to GMO consumption. Unexpected consequences in the environment are also showing up regularly. Until actual, impartial testing has been done, I dont trust the corporate giants and their trained monkeys in the govt bureaucracy to protect us from their efforts to go God one better.
