The Great Lakes are a finite, non-renewable natural treasure - containing a combined total of 6 quadrillion gallons of water — one-fifth of the world's fresh surface water. The lakes span 10,900 miles of coastline along the United States and Canada. The surface area of the lakes is larger than the states of New York, New Jersey, Connecticut, Rhode Island, Massachusetts, Vermont and New Hampshire combined.

In 1998, there was a Lake Superior-based company in Ontario that proposed to take water by tanker out of Lake Superior to Asia.

This proposal failed and spurred the Great Lakes governors to take action. In 2001, they agreed to a framework to begin negotiating the compact. By 2005, they had a deal to take to their state legislatures...the base for the Great Lakes Basin Compact.

It says clearly that the Great Lakes should not be the long-term water supply answer for any other part of the world or any other part of the country.

We still have to solve the saltwater ballast foreign species issue so as to really protect this precious resource. Along those same lines is the potential invasion of Lake Michigan by the huge Asian carp encroaching ever closer through the sanitary canal in Chicago. There is still a LOT to be done.

Great comprehensive clip.
