Can an acre really be so small?? 400x400 doesn't seem like
a lot, but it's 4 acres?? So 200 x 200 = 40,000 which is close
to an acre.    (03)

For some reasons, I can't seem to find any of the earlier posts
on this subject. Still, it's hard to believe that an acre is only
4 thousandths of a square kilometer. That means 250 acres to a
sq km. At 10 people per 1.25 acres, that's (250 * 10) / 1.25,
= 2500/1.25, = 2,000 people per square kilometer.
.
That's twice as many as the 1,000 people per square kilometer
of rice land. More importantly, that's 2000 people who can be
sheltered and fully supported in an ecologically sound way!    (04)

thanks!    (05)
