I have two questions, if I may. I've heard from some that we have an extremely well-developed oil business. Basically, extracting oil and exporting it are very well developed, but we are lagging rather behind in terms of refining oil. I'm wondering if there are obvious impediments in your field to our refining oil.
Second, and this is totally unrelated, I presume from the tenor and content of some of your responses that you are absolutely convinced that global warming is a pressing, live issue for all of us here in Canada and across the world.
