GM foods are not properly tested. No long-term tests have been done. WE are the long-term tests. But so far, in independent studies, GM foods have been found to give rats cancer and creates impotence in cows that are fed GM corn. GM farming leaches the earth through harsh chemicals and pesticides (and god knows what it may do to us). It is not the saviour of humanity as Monsanto likes to claim, but it could be it's destroyer if Monsanto continue to spread its GM seed crops across the world. We need to keep them away from our farms. Mother Nature is far more clever than the gene-splicing scientists. Leave her alone. Or even better, lets work with her. This is the only way to a healthier planet.
