If you gave every man, woman, and child on earth a 1/10 acre allotment (about 20 yds by 20 yds, so a family of 5 gets a spacious half acre for a nice modern western residence and good yard for mowing), you would be able to place the Earth's entire population into...
ARGENTINA.
Now go look at a globe. Now look at the land area that is NOT Argentina.
We are a long, long away away from overpopulation.
(SF has a population density of 17,246 people per sq mi... which gives each person around 1/30 of an acre each... only 1/3 of what I alloted above. If we lived with the population density of SF, we could fit the entire earth's population into Texas.)
The school kids of today are being taught the exact opposite. I would like more to at least contemplate the facts you just presented. Some college professors would lose their positions if they ‘came out’ as NOT being in a panic about ‘Man’s Footprint’ on the earth.
