Some months ago I cleaned out my purse, tossed out un-looked-at scraps of paper, and made a resolution: I decided to choose “no” when asked if I wanted a receipt at the gas pump, ATM, and self-serve checkout. Also, I signed up at my bank for paper-free, online options for billing and paying bills and receiving monthly statements. I’ve had no problems as a result. Now I help save trees, cut down on litter, and avoid worry that lost receipts and statements will end up in the hands of identity thieves. Unfortunately, somehow all that extra room in my purse has been taken up by other junk. Oh well. At least the Earth will be in better shape if not my purse.
