Recommendation

Astrophysicist Martin Rees offers a comprehensive guide to the prospects and options before the human race. Human beings still pose the greatest obstacle to their own survival. Yet Rees believes the world can feel positive about technology and its benefits.

Because Rees strives to explain and illuminate, he leaves the reader with a balanced sense of optimism. This report will prove particularly useful to corporate planners, government officials and analysts.

Alien observers would ascribe these changes to two factors: Humans started cultivating plants and then built cities.

Since the 1970s, extraterrestrial watchers would have noted an increase in the amount of carbon dioxide in Earth’s atmosphere and the launch of rockets. Some of these circled the Earth; others set out to explore the moon and beyond. If extraterrestrials continue their vigil over the upcoming 100 years, what they might see in Earth’s future remains unclear. Would they watch the extinction of life or an improvement of ecological conditions? Could a fleet of rockets set out from the Earth to other parts of the universe?
