Amazon.com description: Product Description: For all the pessimistic talk about the apocalypse, we still really don't know what humanity's future will ultimately look like. Where will our sea levels be? Will avian flu wipe us off the planet? Will computer viruses throw us into darkness and chaos? In this imaginative, gripping book, Fred Guterl, the executive editor of Scientific American, explores six looming scenarios in vivid detail--the way they might really happen. And along the way produces a portrait of where we are today, where we can be with the right effort, and where we might wind up if we're not careful.We find ourselves in a trap: Technology got us into this mess, and it's also the only thing that can help us survive it. Guterl's riveting book is a grand and necessary thought experiment, not merely a scary story, but a fresh perspective on the world we're remaking, which rings a note of optimism about what we're capable of.
