The World’s Water Supply     If all earth’s water fit in a gallon  jug, available fresh water  would equal just over a  tablespoon – less than half  of one percent of the total.  About 97 percent of the  planet’s water is seawater,  another two percent is  locked in icecaps and  glaciers. Vast reserves of  fresh water underlie earth’s  surface, but much of it is too  deep to economically tap.
