Screw Earth Day.  I'm an American.  I have the absolute RIGHT to despoil the environment and lay waste to the planet!  *ducks to avoid the eco-nazi hippies*  :p

Okay, actual answer:  I don't buy into the global warming paranoia/hysteria.  Still, I don't litter, and I run only one burner on the stove at a time to prevent waste of electricity.  I dont' have a driver's license, so I don't drive.  Walk everywhere, unless Ed takes me somewhere, and he has a hybrid.  I'm more concerned about ending dependence on foreign oil than I am about CFC's and contaminants.  The fact that the first will help the second isn't really of much concern to me.  I know, it's politically incorrect.  Don't care.  It's just not one of my priorities.
