It appears you have not discovered the inevitable endgame of our civilization unless humans turn the earth from a closed to open ecosystem by leaving the planet:

But things like the speed of light means it will likely always be a closed ecosystem.  Instead of "more growth" it's also likely the human population craters down to 500 million since the earth only has that much sustainable arable crop land to support humans with.  That and the whole peak oil and natural gas thing.  Growth is over.

The 500 million number on the Georgia guide stones wasn't arbitrary.  Que Anonymint "ya'll beez Malthusian Luddites!"
