I repeat the comment that I made in my prepared remarks that today, by some estimates, fertilizer accounts for 50% of global crop yield, so at the levels of reduction you're talking about, we would expect that if that were sustained on a permanent basis we would see significant impact on global crop production.
Our strategy is to help growers continue to find ways to reduce greenhouse gas emissions in farming and sequester more carbon in soils without sacrificing productivity. Our carbon program is one of the ways we are doing that, by helping growers with conservation practices like no-till farming and cover cropping as well as practices that reduce N2O emissions on the field like the use of enhanced efficiency fertilizers, nitrogen inhibitors and variable rate scripting, all of which have been shown to reduce emissions without sacrificing productivity.
As I said in my comments, cutting fertilizer straight away is just not a viable option, and we have to solve for both of these issues.
