I'm sure Mr. Roberts in Calgary will want to say something too.
On the point about useless activity and pointless activity, I don't think those people who are trying to get to work in Toronto today and who can't buy gasoline will consider this industry to be pointless or useless. That's sort of tongue in cheek, but that's what it comes down to. This is a resource.
I was born in Iran, so I grew up with some familiarity with mining. For me, Canada's mining is about resources, oil and gas. That's why I don't analyze bank stocks; I analyze oil and gas.
Is this important? Is it vital? The oil companies have access to 15% of the world's reserves. If you take OPEC, that's 75%; Russia is another 10% of the world's reserves; and that means there's 15% left over to find the oil that we need so people can get to work. And some of them can't get to work in Ontario today.
We never run out of oil. You made the point earlier about whether we are squandering this resource. We never run out. However, it costs more. And this is why I answered the question about $80 oil. If oil prices go up to $80, you can be sure the operating costs to build one of these things, the capital costs, go up as well.
