With climate change on the mind of the world's policy makers, the auto-oriented design of our cities has been singled out as a major culprit -- and understandably so. Cars burn a lot of fossil fuel, so getting people to walk, bike and use public transportation more would help cut down on pollution and green house gases.
But how to get people out of their cars? The key, many agree, is to redesign cities. Right now cities are designed for people moving around in their cars, so it's unreasonable to expect people to use any other means of transportation. But give them a city that's planned for walking, biking and public transit -- and it could be a whole new ballgame.
