The Earth has approximately 150 million sq. km of land. There are 6.2 billion people on Earth. Now, if everyone alive -- man, woman, child -- was
given 1 acre of land each (1 acre = 0.005 sq. km), then 30 million sq. km of Earth's land would be occupied. That's only 20% of the Earth's land!
Also, keep in mind that 90% of humanity lives on only 5% of the Earth's land -- which, including businesses and other urbanized land, averages
out to be much less than 1 acre per person.
In fact, if you take out China, India, the U.S., and Europe, you'll find that the rest of the Earth is pretty sparsley populated. Indeed, you'll
find that even within China, India, the U.S., and Europe, there are still large tracts of land which are either rural and used for farming and
ranches, or land that isn't used at all.
