It's dicey, but for sure there are differences in different crops. I know there's a good market for non-GMO soybeans—not just organic, but GMO-free soybeans—and that's coexistence, if you want to call it that. I'm not sure how they manage it because I'm not real familiar with soybeans.
But for corn and canola, it's impossible. That's especially the case with canola because it's so prolific in cross-pollination. Plus, it leaks on the truck; it just runs like water. You put it in a truck and it will leak down the highways from a tiny little crack. It's absolutely impossible. It's growing in the sidewalks; it's growing in the eavestroughs, and in livestock and birds. And who's liablel for it? Who's going to pay for the cost of cleaning it up?
