Are there thoughts of looking at that and comparing the two systems? It's interesting that, pretty well from a standing start of zero, in 10 years the market of the organic industry in Canada has gone up to $5 billion. In fact, there's a shortage of organic products in Canada and we need to import that.
I'll move to Mr. Moffat and the variable of feed.
I'm assuming that the greatest emitters of carbon would be more the livestock sector rather than the crop sector. What is the significance of the type of feed when you are looking, not at the yield per acre, but at the number of pounds that a farmer would get per animal, whether it's hogs or...?
