Here is a really naive, unscientific, uninformed and all-around losing idea from Dale Buss, a Michigan writer who served briefly as Milwaukee Journal Metro Editor about 25 years ago:
A five-year-old agreement between the United States and Canada called the Great Lakes-St. Lawrence River Water Resources Compact ensures that the lakes’ waters won’t be shipped wholesale from the region even if the temptation to do so presents itself to one state or province or another...
But the expectation may grow that in an increasingly thirsty world, those who benefit most from the Great Lakes should figure on sharing their fresh-water fortune with the rest of America and maybe beyond. Nothing says the Compact couldn’t be modified or overturned by future political pressures.Notes to Dale:
* Great Lakes water levels are falling.
* Rain and snowfall replenish them at about 1% a year.
* Great Lakes water moved to "the rest of America and maybe beyond" doesn't come back to industries and drinking water systems.
