If you have to resort to agriculture to feed people, than the world is overpopulated.
And the world's entire present population could live in the state of Texas.
They could take up even less room if we pack them like they did at Alcatraz--funny how we equate crowding with a loss of freedom and punishment.
Human beings live on less than 1% of the earth's surface.
Then why do we have to pay for real estate if there is so much of it?
So, upon what criteria do you base your assertion that the earth is overpopulated?
Upon freedom.
Just that it seems like there are too many people in your opinion? Good. Then do us all a favor...
There, there, there . . . in a crowded world, you must learn to be tolerant of people having a ideas different from yours.
