Our survival in space

"To me, the biggest reason is that we eventually have to get off this rock if we want to ensure the long-term survival of our species, in the face of human-caused threats such as bioterrorism as well as natural threats such as meteor strikes or gamma-ray bursts. I've said it before, and the message came through loud and clear as well in William Langewiesche's recent article in The Atlantic and in the transcript of last week's space debate in Washington."

There's a lot of related active links in that paragraph if you follow my link above.

Alan also provided a link to the transcript of WORLDS BEYOND OUR OWN: A DISCUSSION OF PRESIDENT BUSH'S NEW VISION FOR SPACE EXPLORATION a debate between Dr. Robert Park and Dr. Robert Zubrin.
