Thank you.
We've been talking about the future today, and we often forget our most important resource for the future, which is water. In finding solutions for a sustainable future, I hope we're not putting the cart before the horse.
I know that there are challenges with natural gas extraction, in certain instances in terms of hydraulic fracturing sometimes jeopardizing water resources. There are challenges with all fuels and with the use of water in the oil sands, so I'm wondering—this is an open question to everyone—about alternative fuels. What about biodiesel? If we look at biodiesel, perhaps it could act as a stimulant to our agricultural sector here, and we could have domestic production of our own fuel in Canada. Is there a future for biodiesels in the trucking sector in any way? Has it been an alternative that's been explored?
