John Edwards has launched an effort to reduce America’s contribution to global warming by asking YOU to reduce your carbon footprint. (Your carbon footprint is the amount, in pounds, of waste carbon you put into the atmosphere annually.) He has set up ReduceYourCarbon.com for Americans to pledge to reduce their carbon footprint. We, as youth, don’t have as much leverage in this issue (unless, of course, you buy lightbulbs for your family) but you can pledge to reduce your driving by 10% or keep your car tires inflated. Of course, the other suggestions, to raise your thermostat 2 degrees in the summer and lower it 2 degrees in the winter, to weatherize your house, and replace wasteful incandescent light bulbs with more energy-efficient fluorescent ones.
Again, ReduceYourCarbon.com and JohnEdwards.com
