Hot, Flat, and Crowded
Thomas Friedman describes the at one time greatest threat (to humanity), and biggest opportunity (for the US) of this era. How to make a globalized and still globalizing, overpopulated world with a rapidly changing climate a sustainable place where not only the Western world, but the additional billions in Asia, and the billions to be born in the next decades, can live a 'middle class' live. His answer is the 21st century version of the American Dream, a route to new moral leadership for the US, based on three pillars: Clean electrons, Energy efficiency, and Conservation. All those three areas need to be addressed simultaneously.
A very American book, no doubt. But also a very worthwile read to broaden your thinking on what's up ahead, and how your personal role and behaviour fit into it all.
