Recycle every bottle, can, and scrap of paper. Turn off the lights and replace incandescent bulbs with compact fluorescents. Tighten the faucets. Turn off the AC and open the windows. Trade in your SUV for a hybrid. Practice enlightened environmental stewardship -- and, as a reward for your higher consciousness, enjoy the music from the system that you leave ON all the time (except when you hear of an imminent thunderstorm!).
