As I mentioned before, your issues are our issues. We're looking at those. I mentioned that in section 8 we're looking at the policies that exist in other countries and here, and trying to determine if there are comparable rationales for this. We understand, given the population density we have, that we will never have as strong a business case as they do in the European scenario or, for that matter, in Japan, which probably has an even higher density.
We think it's important to look at those elements. The environmental justification for something like this has evolved considerably. The pressures we're facing today were not there 15 years ago. We've never before looked at the economic opportunities that can be realized with something like this, and we want to look at them now.
So this is part of what we're looking at. I guess we're digging in and asking if we are missing something or whether this is just a good idea we'd like to have but is so expensive or unaffordable that the benefits don't justify the costs. We want to look at it. We think it's important to look at all those elements to provide informed information for decision-making, basically.
