If it is wrong to wreck the planet, then it is wrong to profit from that wreckage. - Bill McKibben

Year after year throughout the last two decades they’ve made more money than any company in the history of money. But poor people around the world are already paying for those profits, and every generation that follows us now will pay as well, because the “Exxon position” has helped take us over one tipping point after another. Their sins of emission, like so many other firms and individuals, are bad. But their sins of omission are truly inexcusable.

The expected effects of a sea-level rise typify the many consequences of a global warming. On the one hand, they are so big we literally can't understand them. If there is a significant polar melting, the Earth's center of gravity will shift, tipping the globe in such a way that the sea level might actually drop at Cape Horn and along the coast of Iceland—I read this in a recent EPA report and found that I didn't really understand what it meant to tip the Earth, through I was awed by the idea. On the other hand, the changes ultimately acquire a quite personal dimension: Should I put in a wall in front of my house? Does this taste salty to you? And, most telling of all, the human response to the problems, the utterly natural human attempt to preserve the old natural way of life in this postnatural world, creates entirely new consequences. The ocean rises; I build a wall; the marsh dies, and, with it, the fish.

These new technologies are not yet inevitable. But if they blossom fully into being, freedom may irrevocably perish. This is a fight not only for the meaning of our individual lives, but for the meaning of our life together.
