Thank you.
I think it's really important to take a step back in this debate around climate change. This isn't just about climate change; this is about our entire way of living, particularly within North America. It's completely unsustainable. National Geographic puts out an annual report called “Earth Report: State of the Planet”, and I recommend you take a look at it. It shows in a very graphic way what the world would require if it had the consumption patterns of North America. It would require five and a half worlds, and that is what we're up against. We're dealing now with countries that are developing along the same paradigms and have every right to say they also want to develop along those lines.
Climate change is one manifestation of the unsustainability of this. It has to do with water; it has to do with air; it has to do with all sorts of social systems. It's just not the way we can go forward sustainably. If we tackle this successfully and use climate change as one of the mechanisms in addressing it, it speaks so much more for a future that holds a heck of a lot more promise than what we're facing now.
