The Great Lakes: The Natural History of a Changing Region

The Great Lakes represent the world's largest freshwater system, encompassing nearly 95,000 square miles and holding 95 percent of North America's fresh water. This vast area supports 40 million residents and serves as a critical hub for industry and agriculture. The lakes not only shape the environment but also contribute significantly to the economy and culture of the region, making it a unique area that functions almost like a separate nation within North America.
