You see, even the radical-Left Guardian paper says that we should go back to leaded gas, 8 liter V-8 engines, no catalytic converter gas guzzlers such as those being driven prior to 1968...

The poor Lefties simply have no honest arguments "left". They have to cry that the air is fouler, the water dirtier, and life more miserable; yet who would go back to the days of total smog over Birmingham and cars that would kill you in minutes if left running in your garage?
Any intellectually honest person who reads the Skeptical Environmentalist will instantly admit that our air and water are both cleaner today than in 1968, even though we have more people driving more cars and producing more goods today than back then.
Thus, the Left feels compelled to simply...lie.
