This Is very sad but true. We are destroying this earth by putting out an average person one ton of carbon dioxide each year. The modle T's emissions are still floating around,Takes 1000 years to get out. But we can stop it and we dont have to drive really gay hybrid cars. We can drive cars running off of ethanol. And No you dont have to wait for GM to make there new cars you can run it off most of the cars now.Ethonal has more octane so we should be fine with that. running ethonal is also cheaper so it would help us out alot. Really its not just cars making this mess, its leaving your lights on or your tv on standby. Buy alarm clocks that take two double A batterys you dont need a cd player a radio. You can plant more trees and live in a older house we really need to stop this bull shit.
