I'm a fan of--or should I say, "easily captivated by"--the Big Plan. My current Big Plan is to go carless over the next five years or so. We're making fine progress toward that goal, driving rarely enough that the car has started to pick up spider webs from disuse. But this post is about rather a simple, small way to consume less resources.
Drip dry your hands. Dr. F started boycotting hand dryers (the hot-air kind) a long time ago, due to the beastly temperature they create in a bathroom, especially one already packed with people--one shouldn't come away from washing one's hands feeling sweaty everywhere else.
Once you get used to drip-drying instead of hot air, it's a simple matter to drip dry instead of using up paper towels. Bang--if you're washing your hands as often as your mother would like, a half-pound of paper out of the waste stream.
