Absolutely, yes. I think certainly in the United States, certainly in most parts of the world, we've already gone beyond the threshold of what is desirable. Many people make the argument that these first-generation fuels are a good transition, create the foundation for a transition. But to the extent that's true, we've gone beyond that boundary already, so every incentive we create, every policy we create, should be aggressively focused towards moving towards second-generation options and waste materials.
