Did you know that 70 percent of all processed foods in North America contain genetically modified ingredients? When Vancouver author and five-star chef John Bishop learned that, he decided to investigate exactly what was on our plates. He traveled around the world to find out what the biotech food revolution means for our health and for the planet, a journey captured by director Marianne Kaplan in the film "Deconstructing Supper."

During this special presentation, we’ll also be airing our interview with John Robbins, author of "Diet for a New America" and "The Food Revolution: How Your Diet Can Help Save Your Life and the World." It's a powerful discussion on the most controversial issues in food today.
