Genetic engineering of foods is one of the most controversial subjects of the last two decades. Since humans first domesticated crops and animals, people have bred different breeds and species together, to obtain better plants and animals. Since the 1980's, biologists have been able to create species that could not normally breed. Researchers are able to take genetic information from one living organism, and place it into a wholly-different species. Jeffrey Smith is one of the world's leading consumer advocates for unmodified foods. He recently created a full-length documentary on the subject, called Genetic Roulette. In the film, he discusses the industry, as well as the safety of the food we yet every day, and feed to our children. Smith is our guest on the show today. He is here to talk to us about genetically-modified foods, and how they can impact our health. We will discuss the industries behind the controversial products, and what families can do for protection.
