And while it will be an awesome show, today’s extravaganza is about a lot more than making some snacks and enjoying some good music with friends. Live Earth is a chance to begin something huge and make great strides in changing the way we treat this planet. And no one knows more about this than one Mr. Al Gore.

Who, by the way, personally sent me an email to alert me of the upcoming concert. Well, “personally” might be a strong word. Technically, I signed up for his email list and get updates from him weekly. But that is beside the point; the real point is that Mr. Gore has asked me to sign a pledge to change my actions and make a more positive impact on my beautiful planet. He also asked me to pass the pledge along.

So here it is: The Live Earth Pledge. Read it, click it and sign it. And begin making the difference that this earth so desperately needs.

I PLEDGE:

1. To demand that my country join an international treaty within the next 2 years that cuts global warming pollution by 90% in developed countries and by more than half worldwide in time for the next generation to inherit a healthy earth;

2. To take personal action to help solve the climate crisis by reducing my own CO2 pollution as much as I can and offsetting the rest to become “carbon neutral;”

3. To fight for a moratorium on the construction of any new generating facility that burns coal without the capacity to safely trap and store the CO2;

4. To work for a dramatic increase in the energy efficiency of my home, workplace, school, place of worship, and means of transportation;

5. To fight for laws and policies that expand the use of renewable energy sources and reduce dependence on oil and coal;

6. To plant new trees and to join with others in preserving and protecting forests; and,

7. To buy from businesses and support leaders who share my commitment to solving the climate crisis and building a sustainable, just, and prosperous world for the 21st century.

More important than finding the color of your aura or analyzing your handwriting, the Carbon Footprint calculator is an online test that actually means something.Sponsored by Live Earth, which is set to take the global stage on July 7 with a slough of powerful entertainers giving concerts, the calculator tabulates your “footprint” based on things like your electricity bill, your use of energy – efficient lighting, modes of transportation and dedication to recycling, plus more.

I scored a 220 (not having a car finally works in my favor!). The average American score is 325. You might be surprised by your score, but even more surprised by how easy it is to reduce the force of your tread.
