I get 4.89 square feet.
The world’s population could live in the state of Texas if you grouped everyone in families of 4, with 75 acres, and a 1500 square foot house.
6.92 billion people in 268581 square miles is over 40 per acre, so if they were grouped in families of 4, every family would have 1/10 of an acre.
Overpopulation of the world is a lie ...
In my lifetime I have seen many negative effects of the increase in population. I'm surprised that you haven't noticed any.
My bad.
The square foot space is right for 4 square feet is less than 4.89 square feet.
You are right on the acreage. 1/10 of an acre would be about right.
When I was a teen 84% of Maine was woods. Now it is about 86% thus the impact of population ‘growth’ has been miniscule here - although I have lived in Boston, Manila and on Oahu where it seemed crowded.
While living in the city I would dream of the Maine woods.
From what I have seen the negative effects of ‘growth’ has not been from overpopulation as much as misuse.
