Our new report on GM contamination and contamination escapes shows that some GMOs can be controlled and that some are more controllable than others. When it comes to GM alfalfa, for example, farmers were very concerned about the issue of contamination. When it comes to the GM apple, B.C. farmers were clear that the issue was more about market pressure at that moment in time, although contamination was also an issue. I think it's the biology of the plants and animals that makes a difference in answering that question, though there are other considerations as well. The fact of the matter is that organic production prohibits the use of genetic engineering, but in certain cases, like alfalfa, I think there's a deep concern that, for that particular crop, coexistence is not possible.
