Mr. McLean, to follow up, I'm a little surprised that we don't specifically have climate change. What's stopping that from being part of your plan? You're identifying rising temperatures, but at the same time the public, NGOs, a series of other organizations, and provinces have all recognized climate change as an identifiable factor in their plans and operations. Why don't we have that identified with your strategy? I think people need to understand that this issue is becoming more complex with rising temperatures. And it's not just the days of the zebra mussel on the bow of a ship that came in. It's the mobility of species of plants and animals now that's going to be different because of global warming.
