The Ogalla Aquifer in Nebraska and Kansas seems OK, but it is running
dry in Texas and New Mexico. Aquifers in Yemen, India, northern China,
Afghanistan, Mexico, and Pakistan are being pumped faster than they can
recharge. There is fossil water aquifers in Saudi Arabia, which are
close to running dry. One fifth of the American grain, 3/5 Indian grain,
and 4/5 of China's grain comes from irrigation. India and China account
for 40% of the worlds population. These 3 countries account for 50% of
the world's annual grain harvest. Half the world's population live in
countries with falling aquifers. Forty percent of the world's grain
comes from irrigated land, and 70% of the worlds fresh water is used for
irrigation.

Snip of rest.

Billy, have you seen the movie, "Home" from the Home Project.

You might like it, if you can stay awake. ( I had to watch it twice,
fell asleep the first time.)
