How Obama wrapped up his remarks in St. Paul:
If we are willing to work for it, and fight for it, and believe in it, then I am absolutely certain that generations from now, we will be able to look back and tell our children that this was the moment when we began to provide care for the sick and good jobs to the jobless; this was the moment when the rise of the oceans began to slow and our planet began to heal; this was the moment when we ended a war and secured our nation and restored our image as the last, best hope on Earth.
Can you tell which thing is not like the others, before I finish my song?
This doesn't mean we shouldn't try our best to live and work and eat and travel sustainably. We should! But the ocean is going to rise. And it's going to fall, and then rise again, and then fall again. Regardless of what we do or don't do, or what we do or don't believe, it will happen.
