I'd just like to make a brief comment to follow up.
Certainly Dan's comments about being competitive internationally are very critical to canola and to exporting 90% of what we produce. One comment I would make, which Dan alluded to, is that agriculture has actually reduced its greenhouse gas emissions significantly over time.
If you look at Canola, for example, over the 20-year period from 1986 to 2006, it reduced the amount of greenhouse gas emissions per ton of canola by 65%. Every year farmers have proven that they're really able to be better stewards of the land by adopting innovation. We are certainly positive that we can adapt in the future as well.
