Thank you.
My third question, and probably my last—I guess I have a little bit of time—is the whole idea of innovation, other uses for what traditionally have been food crops--biofuels, carpets, insulin.
We are seeing that as a result of the tremendous impact of the cultivation of biofuels in the south and in the United States there is a drop in the food stock in the world.
You mention, Mr. Dennis, that because of the biofuel industry we have to improve the efficiency of the foods we grow. There is some research showing that what's happening in the biofuel industry may not be that efficient for climate change, may not be that efficient in putting money into farmers' pockets, and is displacing people from land in the south.
Could we possibly not be going in the right direction, and should we not slow down a bit, especially when we talk about the whole issue of feeding ourselves, feeding the planet, and our own national food security?
