The LA Times reports that most scientists don't believe that genetically modified crops have negative health effects:
Meanwhile, the positive effects include fewer pesticides, more targeted insect control, fewer toxic chemicals, and less soil erosion.Genetically engineered crops have been extensively studied. Hundreds of papers in academic journals have scrutinized data on the health and environmental impacts of the plants. So have several in-depth analyses by independent panels convened by the National Academy of Sciences.The reports have broadly concluded that genetically modified plants are not only safe but in many respects friendlier to the environment than nonengineered crops grown via conventional farming methods.For instance, a review this year of 24 long-term or multigenerational studies found that genetically modified corn, soy, potato, rice and wheat had no ill effects on the rats, cows, mice, quails, chickens, pigs and sheep that ate them. Growth, development, blood, tissue structure, urine chemistry and organ and body weights were normal, according to the report in Food and Chemical Toxicology.
