One planet whereon humans live in a hunter gathering economy and which does not outgrow it's natural population balance.
And another planet whereon human population growth runs amok, supported by an ever more complex technology.
Which will still be around a thousand years from now?
(And the bacteria--because simpler is stronger--will outlive both.)
The reason the universe is so silent, the reason we detect no evidence of extra terrestrial high technology, is likely because any life that develops high technology soon perishes.
So the chance of our brief high technological moment, coinciding with signals from another such society living in its brief technological window, is just about nonexistent.
The one with population growth run “amok” will survive. :Lets get Darwinian - geographic diversification is critical for long-term survival of any species. Only a intelligent life that achieves the economies of scale that go with large populations can achieve the geographic diversification that goes with inhabiting other planets and/or spacecraft permanently away from earth.
This so-called balance you want on one planet dooms us to death, a death the can be prevented by preventing us from going beyond earth. This death of mankind in your way of thinking is guaranteed because the sun will expire.
We do not know the hour Christ will come so we need to be around for the long-run.
Good point.
Natural population balance? What’s that?
