What is the optimum population size on earth?
These are the facts & projection:
In 2011 world's population has reached 7bn people. The current growth rate is exponential with adding 1bn people plus every 10 years. The peak is projected for 2050 to reach a level of 9.5bn people on earth.
My question is what is the optimum size of population on earth (and per continent)?
Just some examples, like we all know that bar of chocolate can make you happy but 50 or 100 every day will make you fat and depressive. Or running 5 miles every day will keep you fresh and sporty, but running two marathons every day will ruin your muscles & bones. So obviously there should be always an optimum or at least an optimum range like e.g. the habitable zone in our solar-system.
Are certain areas on earth already overpopulated/underpopulated??
Awaiting your comments:)
