Maybe you could specify, is it the citizens of Alberta, the citizens of Canada, or their governments? Is it the proponents who are there on the ground digging up the bitumen? Who is liable for these tailings ponds, and what is their projected growth from now until, say, 2021, which is the common number used in the natural resources committee report of March 2007? It's the common number used by the Canadian Energy Research Institute, and I think it's a number you might have used earlier. I don't recall. How big are these projected to get?
That would be very helpful for us.
