10 Ways to Stop Global Warming

• Change a light

Replacing one regular light bulb with a compact fluorescent light bulb will save 150 pounds of carbon dioxide a year.

• Drive less

Walk, bike, carpool or take mass transit more often. You'll save one pound of carbon dioxide for every mile you don't drive!

• Recycle more

You can save 2,400 pounds of carbon dioxide per year by recycling just half of your household waste.

• Check your tires

Keeping your tires inflated properly can improve your gas mileage by more than 3 percent. Every gallon of gasoline saved keeps 20 pounds of carbon dioxide out of the atmosphere.

• Use less hot water

It takes a lot of energy to heat water. Use less hot water by taking shorter and cooler showers and washing your clothes in cold or warm instead of hot water (more than 500 pounds of carbon dioxide saved per year).

• Avoid products with a lot of packaging

You can save 1,200 pounds of carbon dioxide if you reduce your garbage by 10 percent.

• Adjust your thermostat

Moving your thermostat down just 2 degrees in winter and up 2 degrees in summer could save about 2,000 pounds of carbon dioxide a year.

• Plant a tree

A single tree will absorb one ton of carbon dioxide over its lifetime.

• Turn off electronic devices

Simply turning off your television, DVD player, stereo, and computer, when you're not using them, will save you thousands of pounds of carbon dioxide a year.
