That's the short answer.

We can reduce our impact on the natural environment by reducing our numbers and by thinking carefully about the way we do things.

Maybe, for example, we don't need cars or suburbs or front lawns to be happy...

It's my own personal belief that we would all be a lot better off if automobiles were not tone of the central themes of our culture. I think it is very likely the automobile culture will fade away as the price of oil rises.
