Will the populations of China and India, comprising a little over one-third of the world
population, outgrow the capacity of those countries to sustain themselves? The answer will
surprise many, but in a way that is most likely totally unexpected.

Is the world overpopulated?
If all of the world's people were located in the Province of Alberta (just a
touch smaller in area than the State of Texas) and each were to have an equal
share of all of the land in Alberta, then each of the world's people would have
98.6m2 of land to live on.
Assuming that the average household consists of three people, a family of three
would have enough space (3,184 ft2) for a moderately-sized house and
a garden large enough to grow some of the food consumed by the family.
- Alberta land area: 661,565 km2, 255,541 miles2
- World population: 6,706,993,152 (Source:
CIA World Factbook, July 2008 est.)
It is obvious that the world's population density will be
the controlling factor. Is that a problem? Will people any time soon
be standing on each other's shoulders?
How can the world be overpopulated if it is possible to fit the world
population, fairly comfortably, into a province the size of Alberta or a state
the size of Texas, even if we divide the whole population into families of
three and give each a bungalow and a good-sized garden to boot?

Does anyone seeing those numbers still think that the world is overpopulated?

Update 2010 08 26: I don't know whether anyone
ever read the assertions
contained in this footnote. If the assertions were read, then everyone
having read them must have thought that they were so outrageous and so totally-out-to-lunch
that they were not even worth commenting on,
because no one ever commented on them. That is odd, given that so many
people claim that humanity must be drastically reduced so as to avert ecological
catastrophes of epic proportions. However, consider something else, Phytofarm,
that is: farming by means of the use of artificial light.
At the current efficiency of PhytoFarm, the entire present population of the world can be supplied from a square area about 140 miles on a side - about the area of Massachusetts and Vermont combined, and less than a tenth of Texas. This represents only about a thousandth as much land as is needed for agriculture at present (give or take a factor of four; for illustrative purposes greater exactitude is unnecessary). And if for some reason that seems like too much space, you can immediately cut the land space by a factor of ten: just build food factories ten stories high, which should present no more problems that a ten-story office building. You could economize even more and build a hundred stories high, like the Empire State Building or the Sears Tower. Then the surface area needed would be no more than the space within the corporate limits of Austin, Texas, to pick the first alphabetically among the many U.S. cities large enough.
PhytoFarm techniques could feed a hundred times the world's present population - say 500 billion people - with factory buildings a hundred stories high, on one percent of present farmland.
[My emphasis ó WHS] To put it differently, if you raise your bed to triple bunk-bed height, you can grow enough food on the two levels between the floor and your bed to supply your nutritional needs.
The Ultimate Resource II: People, Materials, and
Environment (1998), by Julian L. Simon
WHAT ARE THE LIMITS ON FOOD PRODUCTION?
I know, I know. You must think about where all of the
energy to produce the required light will be coming from. Never fear,
Julian Simon thought of that. Read the book and you will find out.
Come on! If you are sufficiently worried about over-population that you
feel driven to stop reproducing and even try to limit other people's wish to
propagate, you must be interested enough to read just one book. No?
You mean you have your mind so firmly made up that no facts will confuse you?
