Is this a world on the brink of catastrophe? There's reason to think so. But as this crucial new book explains, these 'tectonic stresses', massive and frightening though they are, are not the end of the story. From the precarious moment in which we now find ourselves, Thomas Homer-Dixon looks back to ancient Rome and the fall of another great civilization. He shows in lucid and compelling terms how breakdown looms when a society outgrows its capacity to sustain itself. But unlike the Romans, he argues, we are equipped to avert disaster. Armed with hindsight, increasingly knowledgeable about the complex systems in which we live, we may even be able to turn the inevitable changes creatively to our advantage. Everyone with a concern for the future should read this book.
