We are going to learn how to relate to the Earth and our own natural environment here by looking seriously at space colony ecologies.
From Rusty Schweickart
An asteroid can literally destroy 80 or 90 percent of the species that are alive on Earth. These are big events. I mean, this is called extinction.
Americans who read the papers or watch Jay Leno have been aware for some time now that there is a slim but real possibility - about 1 in 45,000 - that an 850-foot-long asteroid called Apophis could strike Earth with catastrophic consequences on April 13, 2036.
Landing on the moon was a dream that millions of kids have had for hundreds of years.
There's no accepted global policy on what to do about asteroid impacts.
All of us know today the value of communications satellites, weather satellites, resources satellites, etc.
By preventing dangerous asteroid strikes, we can save millions of people, or even our entire species. And, as human beings, we can take responsibility for preserving this amazing evolutionary experiment of which we and all life on Earth are a part.
When you look at the origins and evolution of life on Earth, it's been severely affected by asteroid impacts through history.
The frontier in space, embodied in the space colony, is one in which the interactions between humans and their environment is so much more sensitive and interactive and less tolerant of irresponsibility than it is on the whole surface of the Earth.
We have the capability - physically, technically - to protect the Earth from asteroid impacts. We are now able to very slightly and subtly reshape the solar system in order to enhance human survival.
