Backing up from that a little bit, I guess the first question is whether there is a requirement for us to prevent that movement or not. Currently, when we de-regulate and commercialize a GM crop in Canada, for example, there is no requirement to prevent movement, so I guess we'd have to start with a requirement. The discussion has been more about those who want to prevent incursion than about those who want to prevent movement in the first place.
One good place to start is clean seed. We can see, for example in the case of Triffid flax, that the flax industry went right to the seed first and worked with the seed suppliers and the University of Saskatchewan to ensure clean breeder seed, and then worked with farmers to strongly encourage a movement to the use of new, clean, certified seed. That's one important thing, I would say.
