Going green for Lent?

Sacrificing for your faith is the point of Lent, but can environmentalism play a part? Today on the Green Phone Booth, we're introducing you to the idea of Lenten programs focusing on going green for 40 days. Incidentally, I went "green" in an unplanned way - breaking my tendency to reach for the junk food, particularly the stuff that folks bring into work. I'd love some good dark chocolate!
