All right.
This is for Mr. Cross.
You talked about the fact that what's important is to maximize the value that our resources represent. That should really be the goal. The means might be diversification of markets, but that's not a goal in itself. My question to you is whether there should be more diversification in the time direction. Companies, and the managers who manage them, and the people who get bonuses for good performance, they're very interested in short-term returns. I think they discount a lot more than society, as a whole, the future value of the natural resources, energy, accruing to people living in the future. We know that rapid development of the oil sands, for example, means that we're paying a lot for each job that we create. Wages are quite high. We know there are technological advances in the pipeline that will make oil sands extraction a lot cleaner, but in the future because it takes time to build your pilot plant and scale up. We know there's a social cost, which a former premier has talked about.
Is there a sense in which society's value extracted from the oil sands could be maximized if we diversify a little bit more in the time direction?
