I think all corn allergy sufferers should be active in the fight against genetically modified crops. Tell everyone you know to watch this ten minute video. There are feature length films and books out now that help to illuminate the problems we face because of our dependence on GMO corn. Here are links to my favorites:
If you would like to know more but don't want to purchase any of these books or movies, you can rent most of them from your local library. Also, doing a search on YouTube or Google will produce thousands of videos and articles. If you need help explaining the danger of GMOs to others, there is an excellent printable brochure by Jeffrey M. Smith on his website. He is the author of, "The Seeds of Deception" and a famous activist for safer food. He also has a blog on The Huffington Post site.
No matter how you choose to spread the word, the important thing is that you help in some way. Even if you just mention the dangers of GMO corn to a young mother picking out yogurt for her baby at the grocery store, it helps. The continued ignorance of the American public on this issue is the only thing that biotech giants have in their favor.
