In a word, sir, yes. In the context of the three pillars of sustainable development, obviously the issues related more generally to economic conditions are important questions. There's the question of whether or not there are changes in liquidity and what they do, for example, in terms of capital turnover for new technologies, or in terms of energy efficiency gains. This is why the parameters of sustainable development are inherently complex.
I think these types of issues are ones that, for example, the International Monetary Fund just looked at it in a report two months ago on climate change. So I think one of the issues that a lot of countries, including Canada, have taken note of is that environmental issues are inherently related to and interact with economic issues and social issues as well. This balancing issue is something that has to be addressed.
