Okay.
I have another question, on the identity-preserved isolation distances. Mr. Richards suggested there's no level of buffer zone that assures non-contamination. Yet Jim Gowland, from the Canadian Soybean Council, was here a couple of days ago, and he's growing non-GM soybean and GM soybean.
If we were to work towards trying to create GMO-free zones and buffer distances, and that kind of thing, so we could create some type of coexistence, I'm wondering if it's possible to identify crops that buffer distances will work for and crops where buffer distances absolutely will not work.
