Replace your old refrigerator with a new Energy Star: Annual savings: $90; 700 pounds CO2
Set your thermostat down a few degrees in the winterAnnual savings: $135; 1400 pounds CO2
Wash clothes in cold water onlyAnnual savings: $70; 500 pounds CO2
Drive JUST 10 fewer miles per weekAnnual savings: $80; 520 pounds CO2
Reduce your garbage by 10% through greater recycling or reduced packagingAnnual savings: 1200 pounds CO2
Turning off lights saves energy and money. The more energy used, the more rivers are dammed or more fossil fuel is burned, causing air pollution and increased levels of carbon dioxide in the atmosphere.
cars that burn fossil fuels is one of the major causes of increased levels of carbon dioxide in the atmosphere and it is the primary cause of urban smog.
Throwing away containers of any kind wastes energy and resources and adds to our waste problem. Many towns are running out of landfill space.
carry a reusable cloth bag.
SMALL CHANGES CAN REDUCE GLOBAL WARMING
