The Fairest of Them All

I agree with one of the opinion articles on the Yale 360° blog: New York City is the most environmentally sound city in the States.

It is attributable to a simple reason: if it's small and crowded, you don't need a car. A portion of the heat you need comes from neighbors below you. Mass transit is affordable and may even be profitable. Providing energy costs less because you don't need miles of transmission lines; hooking it up to the apartment's central electrical grid is good enough. You only need a few cell phone towers to handle everyone with such high population densities.

Unfortunately, convincing most American people to move into the city core is going to be a lost cause.
