That was the reason I pointed out the benefit of reducing nitrous oxide and focusing on that rather than the carbon sinks, because if carbon sinks...if 45% of the soils or 80% of the soils have already been converted, then it's very difficult for us to make the same type of significant improvement.
I haven't seen any analysis at this point that indicates where and how much we could actually reduce. I think everybody is trying to work to get the best bang for the buck, but at this point in time, we don't have the analysis behind us.
