I would think it would be a marketing initiative, as opposed to getting involved in trying to put some complex regulations around the labels. I think it could be treated as a marketing initiative.
One of the things, though, that is starting to happen is we're finding that retailers are actually starting to demand things like the carbon footprint or environmental footprint. What would likely end up happening is those would evolve into a marketing initiative. Part of that would likely be some type of a verification process to prove that you're actually doing the things you are saying you do. Some of that is actually taking place now with some agricultural commodities. People are documenting what they are doing just to get higher-value markets. That's a conservation footprint or a conservation brand that is gaining widespread acceptance. If you look at some of the more advanced economies, if you take the European Union, for example, they have really advanced their marketing on environmental types of incentives or production practices.
