That’s all. There’s about 1.4 BILLION cars worldwide. If half of those average 10 miles less each week, that would be 7 BILLION fewer miles driven. If the cars average 15 miles per gallon, that would be 467,000,000 gallons of petroleum saved! One gallon of gas = 20 POUNDS of CO2 (according to NASA); therefore, if half the cars on the road traveled 10 fewer miles each week, that would mean 9.3 BILLION pounds (4,650,000 tons) of CO2 did not go into the atmosphere every week! And that may mean thousands, if not millions, of trees might not burn. Ice may not thaw as fast. Weather may not be as severe. Ten miles a week – isn’t it worth trying? See the Blue – See the Truth
