Be ye subtle as serpents
You buy a TerraPass for your car. Mine cost me $49.95, and for it I got a bumper sticker and a window decal. I also got my money spent to support alternative energy production. The lower your car's mileage, the higher the emissions, the higher the cost to offset the CO2. The SUV I used to have would have cost me $79.95, had I bought a TerraPass for it.
This is a quite, non-violent, and yet effective way to work against the bushies. It's along the lines of boycotting Repuglican businesses, by investing in the very technologies they are trying to hold back. And of course, if you take profits away from Big Oil, you take campaign funding away from people like Bush, Cheney, Abramoff and DeLay. Buy your TerraPass today. I got mine yesterday.
