Thank you.
Let me look at it in a slightly different way. There are, as Ian mentioned, what might be regarded as moral questions, the fact that a large part of today's increases of temperature are due to our emissions in the past and that our emissions per capita are simply higher than those almost anywhere else.
The answer I would give as to why we should we do it is that it's because we can do it. I believe there are wonderful and marvellous opportunities available to us for Canada to grasp this nettle and seek to make our contribution to reducing emissions and to producing the sort of economy and industries that will see us into the future.
What worries me is that if I look, for example, at Denmark, they are now the world leaders in wind power. Their government took them there, and they have now a competitive advantage. Similarly, Germany is now the world's leader in solar power. The U.K. are becoming the world's leader in financial instruments. My worry is that if we do not act soon, we're going to be left behind. We will end up on the wrong side of history, and we don't have to be there.
