The easy way to discover happiness, and incidentally to stop global warming in its tracks, is to focus on ecosystems. We are always at the center of our landscapes, but we are never at the center of ecosystems.

If you think of a distant God, you will get a distant idea of what this means.

If you think of ecosystems, you will get an idea of what this means, right here at home.

And so, we have to move beyond landscapes to grok ecosystems.
