Water covers about two-thirds of the surface of earth, but only
0.627 percent of this water is the sweet surface and subsurface
water available for the survival of freshwater organisms including
man (1,2). Some of this fresh or sweet water lies in practically
uninhabitable regions (rivers: }1ackenzie in Canada; Amazon in
Central America; Ob, Yenesey, and Lenta in Siberia, etc.). Also,
most of the major rivers (the Mississippi in U.S.A., the Rhine in
Europe, the Volga in U.S.S.R., the Ganges in India, etc.), because
they flow through agricultural land or urban and industrial areas,
have become highly contaminated with chemicals (3). This leaves us
with shrinking resources of sweet surface water. In the United
States, the dependable supplies of this water are already dwindling
in cities like New York and Los Angeles and states like New Mexico
and Texas (3).
