The Food Guys, Greg Patent and Jon Jackson, don't trust the claims of agribusiness regarding the safety and importance of genetically modified organisms, or GMOs. "The industry asserts it's like natural plant breeding. But anytime you insert genes from one species into another, you're disrupting the entire genetic structure of the organism. Putting a bacterial gene into a rat or a plant might have long-term effects on the physiology of the rat or the plant," says Greg.
