To answer your question, I think there is a cause to be concerned. As with almost anything, you can move into a niche product, but that niche product becomes a commodity pretty soon, just like ethanol will. I think the key is continual science and innovation.
The first in will always make the most profit. The U.S. and Brazil have gotten into this ethanol game very quickly and they have gotten benefits. We're late in the game, so we're not getting as much. If we are smart and we continue to do that research, and we're into cellulose ethanol first, or biobutanol, or whatever, that's the way we're going to guarantee that farmers get benefits and ensure benefits moving into the future. If we stay in the same game and we produce grain-based ethanol five years from now, we're probably going to be high-cost producers and we're going to lose for sure. Innovation is key.
