the world average? And how can we do this while making room-and homes-for

our seventy million new Americans the Census Bureau says will be here by 2060?

And lastly, how can we start planning to create resettlement communities for the

millions of American homes and businesses that will be displaced by sea level rise in the coming decades and centuries? Half of our states are coastal, and we need to plan.

This book ties together the various elements of a new planned cities program and describes how "green" or sustainable cities will be different from cities of the industrial age. It does so by turning much of what we know about city development on its head.

The book isn't just about sustainable building; that's part one, and part two addresses the multiple issues around how to create a place that thrives.
