One thing I look at now is the wheat market in the U.S. There are rumours that North America is going to run out of wheat before the new crop comes in, and if there's a way to grow more wheat on the acres that we have currently, perhaps that is the way to do it.
I'm not a scientist; I don't know the repercussions of that, but it is certainly something we need to consider. If the world gets hungry, we've got to find a way to feed it.
