Evidence of Negative Long-term Consequences of Eating Genetically Modified Food

French scientists recently completed a study on the long-term effects of eating genetically modified foods.  Turns out chemicals only need to be proven to be 'safe' in test animals for 90 days. This study found some upsetting long-term consequences from GM foods, and the pesticides used on them. http://www.naturalnews.com/037249_gmo_study_cancer_tumors_organ_damage.html
