As I said earlier, I view this as a personal matter, as one of the most serious issues we face. We have to address it. The longer we wait, the harder it will be to address it. This is also an area where there has to be cooperation because we all live in the same climate. As each of us contributes to the degradation of the climate, the worse off we all are.
I do think it's very important, for example, to find some uniform way of pricing carbon. If one country prices it cheaper than another country, or one country doesn't price it, then over time all of the heavily polluting industries are going to move there. It's the lowest common denominator.
I do think eventually we're going to get there. This is an area where, quite frankly, there is plenty of fault to go around. My country is by no means without fault on this one and neither is Mexico or Canada. I think the sooner we work together the easier it will be. It will not be easy, but the easier it will be to address it.
