My recollection of my own answer is that I did speak to the combination of forces that are impacting some of the social issues and the social licence and greenhouse gas emissions issues that are obviously important to our business. Those combinations of forces clearly are global.
There is a concern about air quality and what we're doing to our environment. That's coming from around the world. That's coming from social groups, but it's also coming from very traditional sources and from those would-be international investors that are putting pressure on the people in these industries to ensure that they are being good environmental stewards or are at least answering for what they're doing environmentally. I think that is going to be a very important force on the industry, and for a variety of reasons, and it's probably very helpful to our business, because by the same token, these are people who can invest in technologies that we think will help with some of these issues.
We do think government policy is important. There is a cost to using carbon. I think that should be recognized in policy, so there is going to be a government role as well, and clearly there are stakeholders that are impacted. We've heard from the chief today about his circumstances with regard to living in the region of the oil sands. Those are also voices that are very important.
It's a combination of things that's going to get us to a place that makes some good sense.
