A way to visualise CO2 emmssions from your car
From Thomas L. Friedman, Hot, flat and crowded, p 71
A typical car emits 1 pound (they're Americans, that's about 450g to the rest of the world, about half a bag of flour) of carbon dioxide every mile (1.6 km). This is pollution. To help visualise it Freidman suggests thinking of it as a bag of rubbish (you know those McDonald's bags that mysteriously appear overnight); every time you drive a mile, imagine throwing a bag out of the window...now imagine every other driver on the road doing the same (if it's a SUV they get to throw out two bags).
Hmmm...does that help?
