Our Final Century

Book excerpt: Our planet may be insignificant on a cosmic scale, but the evolution of intelligent life here makes it unusual, it is likely to be unique in our galaxy. Yet we may be on the verge of destroying it, of destroying ourselves - over the next century the future of life in the cosmos could be either jeopardised - or safeguarded for perpetuity.Exploring the threats of genetically engineered viruses, nanotechnology, and environmental catastrophe, Martin Rees demonstrates the risks we are taking, as well as the great difficulties of limiting them. Doomsday scenarios are familiar to us all, but rarely are they presented with such authority and knowledge as in this book.
