If you have a moment or two:http://transcendentalbloviation.blogspot.com/2007/04/space-final-window-of-opportunity.html
The essay is a second draft, the first one having come out of an
exchange with Monte Davis. If it looks good enough after
incorporating any comments, insights and references suggested by
people here, I might submit it to The Space Review.
Most people won't know what 'meme' means, which causes a
pause right off the bat. And the last paragragh seemed to
ramble on with little relevence to the idea. I agree with the
sentiment of the essay, that there seems to be an unjustified
assumption everywhere the earth cannot supply our future needs.
That we must move out into space to survive and so on.
For starters, why would anyone think we can build a
sustainable and useful space colony if we can't do so
on earth with all the abundance and advantages on
earth? We must be able to design and manage sustainable
ecosystems on earth before we have any chance
in the hardships of space. And once we have, that
negates the need to colonize space. The only true
justification for colonies is the 'big catastrophe'.
But is it easier to build colonies or easier to
create the ability to protect earth from collisions?
I would say the latter.
I think the idea of the essay needs more support in the form
of examples or facts. For instance, the US population has
a higher growth rate right now then in China. But not due
to births/deaths so much as migration. Showing a correlation
between population growth and economic success might
help paint a better picture of the future. Just as the fact
that population growth rates are expected to fall dramatically
in the future.
