We all know that corporations have but one imperative: to make money. Therefore, why should we trust any of them to make things for us that are not harmful? Analyzing the effects of a product on humans, harmful or beneficial, is not their top priority. In fact, if I am not mistaken, there are many instances where corporations have hidden or minimized harmful side effects of products. This is just one reason why I am against GMOs in the food supply.
Don’t get me wrong. I think Biotech can do some good things. If they find a cure for cancer, great. If they put stuff in our food that has unforeseen consequences, not so great.
