Earth's supply of fresh water dwindles rapidly. There are those who
are convinced this is due to man made global warming. On the other
hand I know people holding responsible positions including a self
made fellow who runs one of the world's largest mining enterprises;
they say: "this sort of thing happens every twenty thousand years
or so, no one's to blame and it will correct itself in its own time."
Guess we educators have a lot to answer for: permitting so many decision
makers to go half educated.
Note: The water that quenches five hundred million of us comes from
glaciers in nearby mountains. The mighty Amazon starts off as a glacier
stream in Peru. And the water that is starting to raise oceans
above their sea walls is being released from melting glaciers at the
Earth's north and south poles.
