Whaaaaa? Erm, maniac,
terminator genes cannot predate GM crops. They're, uh,
genetic modifications to crops to make their seeds infertile. And they're pure evil. They serve no purpose but enforcing corporate ownership of certain plants, regardless of quite real environmental hazards.
As to your claim of GMOs reducing the overuse of chemicals in agriculture... heh. How... quaint. Are you familiar with the logic behind, e.g.,
Roundup Ready® crops? It's not to reduce the amount of chemicals dumped on the crops, it's to
make it easier to indiscriminately dump more on the fields w/o killing off the crop in question. Your general point is not wholly without merit, as there are crops that are made to be simply pest-resistant, but your claim is
far too broad.
You are absolutely correct that problems stemming from monoculture predate agricultural biotech, though I must say a strong case has been made that the GMO agribusiness model makes it substantially worse. Particularly nice is that studies have made very clear that GMO crops cannot be isolated from their unaltered neighbors, so they
will spread; cross pollination
will help reduce agricultural biodiversity. Even nicer is when you have biotech companies
bringing patent infringement lawsuits against farmers who they accuse of "stealing" their product from neighboring GMO-planted fields, or from prior years' GM plantings in the same field. Also, if farmers recover and replant seeds from year to year, that allows for more diversity than if they are contractually obligated to avoid doing so in favor of buying new stock from a central broker each year... to say nothing of the effect of turning loose a more-viable stock of a crop does to non-GM biodiversity in a region.
All of this leaves entirely aside how
wrong it is to leave the very capability to produce food entirely in the hands of a very small number of very large corporations.
GM agriculture is hardly a case where the leftist concerns are "so blatantly wrong". Though since you've willingly donned the mantle of Sensible Liberal to disparagingly chide me into my place as a stereotypical Left-Wing Chicken Little, I'll not hesitate to say that your market-liberal reverence for technology is blinding you to the very possibility that there's problems with these "wonderful" innovations.
But as I said, narrowminded, exasperated, irrational dogmatism is pretty much what I'd expect from a liberal point of view on this topic. "Technology will solve all our problems" + "Corporatism's overall effect is generally good" => "GMO crops
MUST be a net positive, and any evidence to the contrary is bogus irrational chicken-little-ism from the lunatic left".
