In case you haven’t noticed, Live Earth is taking over the world. 24-hours of music across 7 continents is currently exposing billions to global climate crisis. The event marks the beginning of a multi-year campaign driving individuals, corporations and governments to take action.

One way Live Earth is promoting real change amongst us “individuals” is through a personal pledge to take on at least one of the following incredibly simple initiatives:

1. Change four light bulbs to compact fluorescents (CFLs).
2. Shop for the most energy efficient electronics and appliances possible.
3. Shut off energy and lights when not using them.
4. Ride public transit or carpool one of more times per week.

Though seemingly insignificant, just one of the above four options could make a huge difference. Take switching your 60-watt incandescent lamps with CFLs . . . according to the Environmental Protection Agency, if just one million households replaced four traditional lightbulbs with four CFLs we’d eliminate 900,000 tons of greenhouse gases. If every American household changed just one light bulb to a CFL, we would save enough power to light more than 2.5 million homes. That’s doing far more than taking 3.5 million cars off the road . . . permanently.

Maybe you’d rather ride public transportation, or turn your lights off whenever you leave the room. Whatever you do, consider taking the Live Earth pledge. It’s fun, informative, and will motivate you to keep up the good fight.
