Sorry to be so verbose, but has anyone else been thinking about that part in Age of Stupid, when the young Nigerian woman who wants to be a doctor and have a big car and a big house just like in America, says, "Americans live so well, they have everything, its like if you live like that you would never want to die." That line is haunting me.

Right, Tris, that's exactly what I did. I've done several different calculators. Some give the tons of carbon you emit, some do acres required to support you, some give the number of earths we would need if everybody lived like you.

My most quantifiable change has been in driving. I decided I would shoot to stay under 10k miles, but it doesn't look like that's going to happen. My revised goal is 13k. I will sell my car if I have to to stay under 15k. Last year with life and travel I drove 30k miles, which is just absurd.
