Many GMO products are perfectly fine, with little downside potential. It's fine if people want to avoid all GMO products, but I put this on the same level as the tens of millions of people who have suddenly decided they are "allergic" to gluten. About one percent of the population has a problem with it, but it has become a fad. I saw an ad on TV for a vitamin pill that is non-GMO and gluten free. Whoopee fucking doo.
But the development of grains that are resistant to a specific herbicide - Roundup - I consider a terrible idea, with potentially devastating results.
