When it comes to sustainable lifestyles that aren't as dependent on automobiles, America is at a disadvantage since so much of our country was populated after the advent of cars. You have cities like Atlanta, GA, which is expanding very rapidly and has suburbs that have no sidewalks, and nowhere to walk to anyway. Our towns are planned around the automobile.
So for America to move away from the dependence on cars, we'd have to re-think a lot of stuff. But for a nation that's where we were 50-60 years ago, perhaps they can learn from our mistakes & try to ensure their towns are centered around walkable activities so their citizenry at least has the choice.
