Eric, this is the trap set which you've just walked into. You're conflating environmental damage with the Carbon dioxide issue. They're not remotely related. No one is against energy efficiency. Try applying some economics to the fuel efficient cars. It's all great and good, but entirely meaningless to the CAGW issue. You don't have to be a scientist to understand a few mpg increases will do nothing toward the global atmospheric CO2 levels. The economic hole we've dug, is in part, because of the CAGW idiocy. We're paying higher prices for energy and fuel...... what does that do to an economy? Apply a cost/benefit analysis to any CAGW inspired project and you'll see it isn't worth it.
