Thank you, Chair.
And thank you both. These were interesting presentations, from both of you actually—especially, Professor Van Acker, this issue about the science of the unintended consequence, if you will. When a material is introduced, it's expected to do something, but unfortunately it may move—and does, according to the studies you're quoting and some of the studies you have performed yourself. I noticed in your written brief that you have actually participated in many of the studies. As much as we may not want it to, the material does move, and with that movement there is a potential for it to be where we don't want it to be, I suppose. I don't want to call it a risk per se.
Based on the fact that it does move, are there things, in your view, that we can do to mitigate the fact that it's in places we don't want it? You cited canola as being in the roadside, for instance. Most farmers aren't harvesting the roadside; it's simply there. Are there things that in your view we can look at to try to mitigate that movement, this particular unintended consequence?
