SMALL CHANGES CAN REDUCE GLOBAL WARMING

Replace your old refrigerator with a new Energy Star:

Annual savings:

$90; 700 pounds CO2

Set your thermostat down a few degrees in the winter

Annual savings:

$135; 1400 pounds CO2

Drive JUST 10 fewer miles per week

Annual savings:

$80; 520 pounds CO2

Reduce your garbage by 10% through greater recycling or reduced packaging

Annual savings:

1200 pounds CO2

Wash clothes in cold water only

Annual savings:

$70; 500 pounds CO2


SMALL CHANGES CAN REDUCE GLOBAL WARMING

  • 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

  • Reduce the usage of hairdryer.

  • Reduce the usage of tissue paper.

  • Changing one bulb could save 150 pounds of carbon dioxide per year!


Our take-home message…

Each of us must take steps to protect our Earth's climate.
