If all the earths water is fit in the gallon jug,available fresh water
would equal a tablespoon- less than half of
one percent of the total. About 97% of the planets water is
Sea water; another 2% is locked in the ice caps and glaciers.
Vast reserves of fresh water under lie earths surface,
but much of it is too deep to economically tap.
WE HAVE ONLY 1% FRESH WATER.
