What can a wild lake teach us about the world? In the 1850s, Henry David Thoreau published his book "Walden." He used his experience living on a small lake near Concord, Massachusetts to think and write about relationships between nature, human life and time.
In his new book, called "Still Waters," Dr. Curt Stager from Paul Smith's College in the Adirondacks does much the same. He uses scientific data gathered from lakes all over the world to ask equally difficult questions about climate change, stewardship and the growing impacts of climate change and a rising human population.
