Our Final Hour: A Scientist's Warning - Martin Rees [epub]

Bolstered by unassailable science and delivered in eloquent style, Our Final Hour's provocative argument that humanity has a mere 5050 chance of surviving the next century has struck a chord with readers, reviewers, and opinion-makers everywhere. Rees's vision of our immediate future is both a work of stunning scientific originality and a humanistic clarion call on behalf of the future of life.

Just when you've stopped worrying and learned to love the bomb, along comes Sir Martin Rees, Britain's Astronomer Royal, with teeming armies of deadly viruses, nanobots, and armed fanatics. Beyond the hazards most of us know about--smallpox, terrorists, global warming--Rees introduces the new threats of the 21st century and the unholy political and scientific alliances that have made them possible. Our Final Hour spells out doomsday scenarios for cosmic collisions, high-energy experiments gone wrong, and self-replicating machines that steadily devour the biosphere. If we can avoid driving ourselves to extinction, he writes, a glorious future awaits; if not, our devices may very well destroy the universe.

What happens here on Earth, in this century, could conceivably make the difference between a near eternity filled with ever more complex and subtle forms of life and one filled with nothing but base matter.

For many technological debacles, Rees places much of the blame squarely on the shoulders of the scientists who participate in perfecting environmental destruction, biological menaces, and ever-more powerful weapons. So is there any hope for humanity? Rees is vaguely optimistic on this point, offering solutions that would require a level of worldwide cooperation humans have yet to exhibit. If the daily news isn't enough to make you want to crawl under a rock, this book will do the trick. --Therese Littleton

From Publishers Weekly

Nano-machines stand poised to revolutionize technology and medicine, but what happens if these minuscule beasties break their leash and run amok? Rees, the U.K.'s Astronomer Royal and prolific author (Just Six Numbers; Our Cosmic Habitat), warns that the 21st century may well witness the extinction of mankind, a doomsday more likely to be caused by human error than by a natural catastrophe. Bioterrorists are the most widely publicized threat at the moment, but well-intentioned scientists, Rees says, are capable of accidentally wiping out mankind via genetically engineered superpathogens that create unprecedented pandemics, or even through something as weird as high-energy particle experiments that backfire and cause the universe to implode. Rees poses some hard questions about scientists' responsibility to forsake research that might lead to a malevolent genie being let out of its bottle and even to restrict the sharing of scientific information to prevent it from getting into the wrong hands. Ultimately, though, Rees sounds more alarmist than precautionary. Some may find him overly optimistic on what science will be capable of doing in the next quarter century. Rees makes some provocative points, but the book falls short of what readers expect from a scientist of his stature.
