Here's your Earth Day challenge:
Replace the light bulb you removed on Day 2 of our challenges, but only after considering whether you really need it. If you do, replace it with a compact fluorescent lamp (CFL), which can save 150 lbs. of carbon dioxide a year. And why not help someone else cut their emissions by giving them a CFL as a gift as well?
See you tomorrow ...
