Perhaps I could help Mr. Gravelle. There was a report put out by the National Round Table on the Environment and the Economy called “Achieving 2050”. I happened to be on the national round table at the time this report was put out, and it did an evaluation of cap and trade. One of the things I found most interesting about that particular report was that it showed rural people and low-income people would be the hardest hit by cap and trade, so it's a very strange position for a political party to advocate hurting low-income people.
I would like to ask a question on environmental performance. Would you say that our natural resources and energy industries are getting cleaner and cleaner as the decades go on?
