If you're looking for a great read that discusses creating a sustainable future...I highly recommend reading Hot, Flat and Crowded by Thomas Friedman.
You know may his other work, The World is Flat.
Here's a description from Amazon:
"Friedman explains how global warming, rapidly growing populations, and the astonishing expansion of the world’s middle class through globalization have produced a planet that is “hot, flat, and crowded.” Already the earth is being affected in ways that threaten to make it dangerously unstable. In just a few years, it will be too late to fix things--unless the United States steps up now and takes the lead in a worldwide effort to replace our wasteful, inefficient energy practices with a strategy for clean energy, energy efficiency, and conservation that Friedman calls Code Green."
Let me know what you think!
