"Cities offer us powerful leverage on our most stubborn, wasteful practices. Long commutes in our cars, big power bills from our energy-hogging buildings, shopping trips to buy stuff that'll spend a few short months in our homes and long centuries in our landfills.
These are unsustainable behaviors. And they're so difficult to change because they're spun into the very fabric of our cities and sprawling suburbs. Reweave that fabric, and we find change much easier."
