ABSTRACT
Philosophically, “The origin of all matter is water,” said Thales. The largest constituent of the universe is hydrogen, which makes two of the three atoms in water (H2O). Scientists believe that liquid water is prerequisite to life, and we know with certainty that the first life forms flourished in the oceans. The Code of Hammurabi (1790 BC) for the State of Sumer lists several laws pertaining to irrigation that address negligence of irrigation systems and water theft (Hatami and Gleick, 1994).
