Maybe I'll move over to Mr. Hooper.
I was part of the Ontario government a long time ago, in my youth, and I remember our talking about increasing ethanol in our fuels. I remember there being some concerns from a number of people that if we have more ethanol, we're using more land for corn. If more land is used for corn, there's less land for food, and if there's less turnover of land, it's bad for the land. There are all these kinds of side effects. It's kind of this cycle. I remember that as an argument. This is from over 10 years ago.
I wonder whether we've actually addressed some of those issues as we're trying to advocate for more advanced biofuels as part of the solution to actually reducing our overall carbon emissions. Can you maybe talk to that?
