One of the bigger contributors to global warming, in my opinion, is the roads we drive on.

I read somewhere that the average two-lane road is 19 acres per mile. So now with every new road built here in the U.S., for each mile we're replacing carbon-dioxide absorbing plants with heat-absorbing blacktop.

I'm not saying we should all drive on dirt roads, that's not an answer, but maybe we should consider a lighter less heat absorbing surface material?
