Op-Ed: Do you know your ecological footprint?

Toward the end of each year, I take a few minutes to run my personal Ecological Footprint scan to see if I can get a handle on how I am doing relative to myself, to others and to the planet. Seems like the least I can do, not less because it does oblige me to think about my life pattern and choices in the greater scheme of things. “Walk the talk”, etc., etc. (PS. On a more global basis, to get a feel for where the high scores hang out, this map of earth lights at night will provide you with some good clues.)
