We also produce 25% of the worlds natural resources.

There expected to last for centuries at least.

The mining and manufacturing do cause pollution, and moving it off planet 
would help, but I canít see anyone agreeing to export a major fraction of our 
economy even ignoring cost problems.  (Though I do expect Mining and 
manufacture will move off planet in the coming centuries, for these and other 
reasons, I don't think so in the next couple decades.)

FOOD!!  I'm doubtful space platforms would grow their own food, being able to 
compete with Earths domestic sources in domestic markets?!!  No way!
