Expansion & Contradiction: Oil spills and personal will

"This Full Moon in Sagittarius encourages us to expand -- our minds, our vision, our faith, our perception" —@astrogrrl

The Gulf Oil Spill has been troubling me no end. Sitting here in California, it's raining, and I'm wondering how the f**&^ do you even start to help? Sure, yeah, I ride my bike, walk, BART, carpool, City Carshare, don't eat meat, etc. I also get on airplanes, add gas to those CityCarshares, spend a lot of time in creative pursuits that may entertain...but help, I'm not sure. So I'm looking to this full moon tip. How to expand, meaningfully, without harm?
A thought for the day.
