<br/><br/> Confident that an endless supply exists in lakes, rivers and streams, man has polluted and wasted water in many parts of the world.  Elsewhere because his land has become parched, withered and scorched by drought man has packed up his belongings and migrated thousands of miles to relieve his thirst.  Of all the water on earth more than 97 percent is in the ocean and not fit to drink and too salty for irrigation.  Within twenty years man's demand for water will double.  In many areas the most economical step lies in desalting the sea.
