0) Moving all our heavy industries into space is the solution
to many of
mankinds problems.
1) need more energy, build a larger reflector.
2) need mineral resources, capture earth orbit crossing
asteroids.
3) need protection from dinasour killers, see 2)
4) different groups want their 'own space to live in', see 0)
5) tired of being poor? see 0)
6) earth is getting polluted, see 0)
7) species are being exterpated, see 0)

once we climb out of the cradle, we can clean the
earth up, turn it into parklands and bring back those
species that mankind exterpated.

Warning, if we don't do 0) soon, we will have
exhausted the vast store of fossil solar energy that
would have allowed us to climb out of the cradle.

For what it is worth, the lion's share of energy,
and water, (and consequently wastewater) is
consumed by homes... not production facilities.

Support facilities and workers for the production
facilities would also move.

So you move "everything" into space. Leaving only "remediators"
and caretakers behind?

Eventually most people will WANT to move. Those that want to stay behind
will. Those that stay behind will be interested in remediation and
caretaking. Why else would one want to subject one's body to the punishment
of living at 1g when they can live much easier in microgravity?


Rather than be a solution, I'm afraid Earth
would just be our dumping ground in your scenario.

It WILL take a while to clean up the mess we
have made. But climbing out of the cradle will
give us the time.

If we stay in the cradle, our time is very limited.

We cannot clean up our mess, because we always make more. We are
engines of entropy. However, we can work in concert with our
environment... but not at the population levels we currently
have.

Exactly correct.


It costs us thousands of dollars for each pound
delivered to orbit, and we simply dump spent /
damaged parts Earthward.

Every dollar spent on putting something into orbit
has gone to feed someone.

*Lots* of someones.

We (there is a we including you and me) are the partakers of the benefits
of the space race. These computers we are using to talk to each other would
never have existed absent the space race.


The value of the mass of elements we have orbited
is very small and more than counterbalanced by
infalling mater from space.

It took energy to form those materials, and yet we vaporize them
and spread them over the globe. And this is from a few hundred
"out of cradlers". Discipline starts at home, it doesn't come
from being in a frontier.

The frontier WON'T be in NEAR-EARTH-ORBIT. It will be an ever expanding
sphere centered on this solar system.

The money goes to pay people's salaries as they
mine minerals, refine ore, machine parts, design
machines, advance technology, invent things, build
rockets, write papers, etc.

Every penny stayed here on earth.

Money is only a unit of trust. The trip out of the cradle will
keep people employed, but, will *not* necessarily change who we
are. If we change who we are first, maybe then getting out of
the cradle will be easier... fun rather than "escape from doom".

Changing 'who we are' may take millions of years. We don't have the luxury
of waiting that long.

Removing the current 'scareity based economic system' and replacing it with
a system based on human ingenity may be a precursor to 'changing who we
are.

The spend/damaged parts are a drop in the
bucket compared to the tons of trash and obsolete
consumer goods discarded by households each year.

All will still be generated in space. And what is more, one will
be consuming one's own excreta... rather than that of our
ancestors (processed by a massive biosphere). We move closer to
imminent disaster, not further, should safety systems fail.

'Waste' is 'resources out of place'.
Given sufficient energy, 'Waste' is a valuable resource.

We move closer to imminent disaster each second right now.

The next big chunk of space rock will end all our petty squabbles and any
worries about pollution.

After we get out of the cradle scarce natural resource
will no longer be a limiting factor. The ONLY scarce
resource will be the human mind.

We need space travel. But more than this, we need a frontier.

Yep.

Minds we've got. But they hardly ever look up from the navel.

Better to use our minds in a constructive way than in the intricate games
of 'one upsmanship' that I see on the internet every day.

I
like your intention, *and* the discipline needs to start here and
now.

Today is the first day in the rest of the life of the human species.
Unless we get out of the cradle, any minute may be the LAST.

This REALLY is the MOST important problem that faces you, me and the rest
of our fellow travelers upon this good earth.
