My next question is to Gretchen Fitzgerald.
I appreciate what you were saying about the challenges of cleaning up the environment, and the previous government and our government have been struggling with that. The entire world is struggling with that, quite frankly. We may have slightly different opinions on where we go, but one great thing worries me about the Kyoto challenge, and that is the fact that we're not bringing the entire world under the same blanket.
Quite frankly, under the aegis of Kyoto, if we followed the Kyoto mandate to the letter and we allowed India and China, those big third world economies, to continue to build just at the rate they're building today, not to be increased, we would double our greenhouse gas emissions by 2050.
So beyond Kyoto, what else has to happen?
