I am an elementary school librarian. I have been anxious to join a movement whose members are all so conscientious about protecting our earth and conserving our resources for future generations. My biggest sacrifice is in sharing one car, a Prius, with my husband. It means lots of walking. One day I’d like to get a bicycle. Our thermostat is set a 63 degrees. We recycle and try not to be wasteful, but there is so much more that we could do to improve our carbon footprint. Thanks for this opportunity.
