Space Development And Earth's Future

apsmith writes "In the New York Times' Sunday Book Review Dennis Overbye reviews British Astronomer Royal Martin Rees' new book: Our Final Hour - A Scientist's Warning: How Terror, Error, and Environmental Disaster Threaten Humankind's Future In This Century--On Earth and Beyond. The book paints an exceedingly grim picture of our future - Reese gives humanity only a 50-50 chance of surviving the 21st century, with all the potential for calamity we have unleashed (and that nature may have in store for us too). But the book isn't just doom and gloom - we CAN do something, and the answer lies in space. But NASA has been doing it all wrong. Interestingly enough, this coming weekend is the International Space Development Conference in San Jose, where you can find out the latest ideas on how we really should be settling space."
