The carbon footprint issue is that off that same acre of land that in 1975 was producing 100 bushels.... You can do the math; it's 56 pounds a bushel. You can crank out how many tonnes and all the rest of it. Essentially, we've doubled the yield on that one acre of land in this period of time. That means we reduced our environmental footprint in an overall fashion.
We're also pulling back now the ethanol to take it to the transportation sector, and allowing that to be lowering our emissions. We've taken the other transportation fuels, such as from Nevin's canola or from soybean, for biodiesel. That's if we could get this stuff up; we have a 30-megatonne ask coming at us from the federal government to make fuels a reality, but the bureaucracy has stalled that program from going forward. We don't know where it's going to be. It's back to the point that without clear policy, we can't move this stuff. You can't invest without clear policy.
