If I were looking at a biofuel future, first there are going to be genetically engineered crops that will likely be specifically designed for oil or ethanol production. I think you're going to see some work done on that. The other thing is taking a look at some of the field crop waste. You look at crops that have been harvested—straw, stover; there are a number of those fibres that could be put into a system. I could see a future where farmers might be combining their resources with municipalities, of livestock manure, crop waste, municipal waste, going into methane digesters. Instead of feeding natural gas into the lines, we'd be feeding methane in. There's great potential for some of that, but that's going to take research, development, innovation and partnerships. Like Brian and Rick, I see a very positive future for agriculture in the potential that we can move ahead on some of these.
The other thing is I think we have to take a look at the forestry sector as well and see if there are things we can do, particularly on the biofuels and bioproducts side, to see if there are opportunities to produce more products from renewable resources.
