I'm not going to get into a political debate with you, but it seems to me that the federal government has a lot of levers at its disposal, and if our natural gas resources.... For example, if you look at the petrochemical industry, they're looking for feedstock, and we also have huge volatility in terms of natural gas. I think it is a legitimate question for the federal government to ask whether this is the highest and best use of our natural gas resources. I think if we were creative, we'd find ways to deal with that.
I'd like to come back to another question, and that is not to put you on the spot as to whether you think we should slow down or have a moratorium with respect to the oil sands development. If the Minister of Natural Resources came to you one day, Mr. Brown, and said he's been swayed by all these arguments that we should slow down the development of the oil sands or put on a moratorium, I'm curious to know what the levers of the federal government are in this area. Clearly, there are some provincial levers, but what are the levers the federal government has if they wanted to proceed in this way?
