Water provides the Earth with the capacity of supporting life. An
organism doesn’t have to be told how important water is to their
existence. An amphibian knows to lay their eggs in water or else there
will be no new born. Even flies know to lay their eggs in fresh water.
The only organism that doesn’t understand the importance of water
is humans, especially in industrialized countries. Children in those
societies turn on the water in a sink and never think about the trouble
someone has gone for that "miracle" to occur.
In the United States it is mandated by law that its citizens should
be given clean and abundant water. Dams, reservoirs, filtering
plants, and pipes all bring clean water when the facet is turned on.
Sewage water is only mixed with recycled water supplies after the water
goes through rigorous cleaning methods. Water borne diseases do not
effect the U.S. population like in other countries that do not treat
their water supply.
