“...thoughtful, beautiful, and enlightening...” —Jane Jacobs “This book will have a lasting infl uence on the future quality of public open spaces. By helping us better understand the larger public life of cities, Life between Buildings can only move us toward more lively and healthy public places. Buy this book, fi nd a comfortable place to sit in a public park or plaza, begin reading, look around. You will be surprised at how you will start to see (and design) the world differently.” —Landscape Architecture
You can however plant a lot of trees which would make a huge impact on the sustainability of cities by regulating the heat/cold much better. Also if you look at old European cities you can pretty much compress away all the car space. Jan Gehl's "Life Between Buildings: Using Public Space"[0] is a fantastic read if you're into thinking about this sort of thing.

> Gehl's book Public Spaces, Public Life describes how such incremental improvements have transformed Copenhagen from a car-dominated city to a pedestrian-oriented city over 40 years. Copenhagen's Strøget carfree zone, the longest pedestrian shopping area in Europe,[2] is primarily the result of Gehl's work. In fact, Gehl often uses the phrase "copenhagenize" to describe his vision of how urban centres can embrace bicycle culture and urban cycling.
