People don't realize the massive amount of emissions from using their car because they don't see the massive amount of material they put into their car every time they fuel up.

A 20 gallon tank produces 400 pounds of CO2 for every fill up.

Even manually filling a tank by lifting a series of five gallon containers would seriously reorient the average person's conception of their fuel usage.

Yeah, and the most deceptive thing is that burning 1 lb of gasoline produces about 3 lbs of CO2.
