Our final hour

Sobre el libro Our final hour de Martin Rees publicado por Basic Book al 2003:

How terror, error, and environmental disaster threaten humankind´s future in this century - on earth and beyond.
A scientist known for unraveling the complexities of the universe over millions of years, Sir Martin Rees now warns that humankind is potentially the maker of its own demise - and that of the cosmos. Though the 21st century could be the critical era in which life on Earth spreads beyond our solar system, it is just as likely that we have endangered the future of the entire universe.Rees maps out the ways technology could destroy our species and thereby foreclose the potential of a living universe whose evolution has just begun. He also forecasts the startling risks that stem from our accelerating rate of technological advances. We could be wiped out by lethal "engineered" airborne viruses, or by rogue nano-machines that replicate catastrophically. Experiments that crash together atomic nuclei could start a chain reaction that erodes all atoms of Earth, or could even tear the fabric of space itself. Through malign intent or by mistake, a single event could trigger global disaster. Though we can never completely safeguard our future, increased regulation and inspection can help us to prevent catastrophe.
