I have just read this book for the second time, and marvel once again at the extraordinary care taken by Dr. Langston in presenting, in great depth, the history of human use and abuse of our most precious resource in the Upper Great Lakes--Lake Superior. Industrial level logging and mining operations in the Superior watershed region, are industries which took and are still taking advantage of the quantity and quality of its "pure" water. Under Langston's careful scrutiny, they are called out for what has to be the most common 'power' word in the book: POLLUTION in its many guises and transformations.
She documents the efforts of those who have tried to stem, halt, or block such disregard for this valuable resource, and the energies that have been brought to this endeavor, not always in vain, but most often with little success, either. Clear heroes are the American Indians of the region, who value the water, the land, the flora and fauna, and stand as the protectors of same. They are exercising their treaty rights, which while often abused, have been upheld by the US Supreme Court.
I can think of no-one to whom I would not recommend the reading this book, twice or more times. For our politicians it is an absolute MUST READ. Yes, it's long, yes; it's slow going; it has to be, so that the message sinks in: Lake Superior is a unique treasure, and should not be subjected to abuse by anyone. It will benefit all who come to it, but it cannot take unsustainable use and abuse, as has been happening over the years since European colonization. Change in our human behavior is imperative.
