GMO’s create a societal harm, not a physiological one. Patenting a cultivar of a plant is a slippery slope, and we have already had quite a slide. In theory, if somebody works very hard to breed a new cultivar, they deserve to reap the rewards of that work and protect their creation. Okay, that makes sense. But if I have all the ingredients to breed that same cultivar, and do all the same work myself, should they be able to restrict my ability to profit? A step farther, and this is the reality we inhabit. Monsanto has created an environment where their patented corn seed is the best bet for a profitable harvest, but farmers are required to sign highly binding contracts with ridiculous stipulations. Beyond that, if a neighbor farmer dares to plant non patented seed, and the wind blows his neighbors Monsanto pollen (corn is wind pollinated) into his field and it pollinates his crop, he is now in patent violation of a company he has no business with that is now going to aggressively come after him in court. This is actually happening in the American Midwest.
