Do you keep your thermostat below 60 degrees all winter? Turn off your hot water heater from May to November? Eschew the needless acquisition of plastic bags? Attend any event or festival whose title contains “Eco” or “Green?” Drive a hybrid car or day dream about installing a wind turbine on your roof? Submit a brief note attesting to your conservation efforts, quirky or mainstream, and we’ll send you a free t-shirt or baseball cap. The truly compulsive conservationists may get a polar fleece jacket. Thanks for minimizing the combustion of fossil fuels.
