Thanks Pea! I was extremely happy not to see my cats food listed as having gm ingredients. phew! just what I need gm cats!
That's not quite how it works... I know you're partly joking but it's a common belief that eating GM foods could somehow result in "GM genes" entering the eater's body. If this were in fact the case, we would all be now expressing countless genes from every food organism we've ever eaten.
I'm a molecular biologist and am greatly distressed by a lot of the misinformation going around about GMOs and GM foods. I know a lot of these can be ascribed to poor communication of what are in fact quite complicated ideas, but many others are, I think, the result of some sort of misguided "vitalism" or belief that creating something artifically makes it inherently suspect.
That said, my major concern with how genetic modification has affected the food supply is economic - it results in a small group of patent-holders having incredible control over the growth of basic foodstuffs. Farmers need to make a living, and so if they choose Roundup Ready canola, it's likely because it makes them money in the long run. The downside of this (aside from increased RoundUp use) is that Monsanto now has IP rights over much of the crop, and can dictate the terms under which it is grown, and indirectly, the price. As we've seen, Monsanto and other large corporations can't be trusted to exercise their current IP rights responsibly - the Schmieisser case being a good example. And of course they're constantly lobbying government to extend IP holders' rights beyond what is reasonable to insure that innovation is profitable. Having that kind of ruthless monopolism impact the food supply is not desirable - and will certainly not lead to the feed-the-world bounty that the corporate GM proponents still tout.
