A few weeks back we went to see the recent documentary "An Inconvenient Truth" with some friends of ours. It was an interesting film regardless of your political views. To see some of the images presented was shocking. It may seem to some like this whole issue is made up and that no one really is buying it. Fine, you can have your opinions, and I will hold to mine. But I am led to believe that whether you believe changes in climate are happening or not we have a responsibility to use our natural resources wisely. Using less electricity, gasoline, and creating less waste are simple ways to conserve and save what we have been given.
One simple thing anyone can do (and it saves money) is to switch the five most used light bulbs in your house for Compact Fluorescent Light Bulbs. These bulbs use less energy to light, and last 10 times longer. If everyone would change the most used bulb in there house "it would prevent enough pollution to equal removing one million cars from the road" (www.energystar.gov).
For other energy saving advice look at the Sierra Club's list.
