GMO food might be as bad as some claim it is, but I am not persuaded of it yet. People are upset over plants that have been engineered to be resistant to herbicides or to certain insects. But then, there are a lot of those in nature too. In my part of the world, there are two very dramatic ones that occur naturally. One is the endophyte that lives in symbiosis with tall fescue grass. It can be really toxic to animals under certain conditions, but the real “purpose” of it is to kill insect pests. Black walnut trees produce a powerful herbicide. Almost nothing will grow under a black walnut other than grass, and not every kind of grass either.
Somehow, over some number of eons I don’t know, those plants developed insecticides and herbicides that beat just about any that humans come up with. And there a lot more of them than those; those two are just dramatic enough to be obvious. But somehow or other, natural selection or something caused plants to develop those things, and we don’t think anything of them. Cattle eat tall fescue (and sometimes get sick from it in dry weather) and we eat the cattle. We eat black walnuts without a thought to the herbicide, and plant those trees in our yards.
GMOs do those same things. Perhaps, for some reason, they’re worse than naturally-occurring pesticides and herbicides. But I have not seen anything really scientific that tells me they are.
Some GMOs are resistant to herbicides; like “Roundup ready” corn. Maybe that’s a bad thing when one consumes the corn. But I have not seen anything really persuasive that it is. But then, there are plants, like wild blackberries, that are powerfully resistant to the same herbicides.
And corn itself is “unnatural”. Corn can’t survive without human intervention. If people didn’t raise it, there wouldn’t be any. Somehow, Indians developed it from some grass or other, and nobody, to this day, knows how they did it or how long it took to get it done.
The prized vineyards of Europe are “unnatural” and would die out in a couple of years if not for human intervention. Every last one of their vines are sitting on American wild grape root stock originally from southwest Missouri and northwest Arkansas. Why? Because a naturally occurring mite would have caused them to go extinct in the 19th Century; a mite with which wild grape American rootstock lives symbiotically.
Domestic strawberries are “unnatural” too. A patch of them will die out quickly without human intervention notwithstanding that wild strawberries (from which they were modified) can survive without it.
I’ll quit here, but I guess humans have been “guinea pigs” for a lot of things for a long time.
