<DIV>An environmental engineer turned ecology writer relates the history of our waterways and her own growing understanding of why our waterways continue to be polluted?and what needs to be done to save this essential natural resourse.<I>Water: A Natural History</I> takes us back to the diaries of the first Western explorers; it moves from the reservoir to the modern toliet, from the grasslands of the Midwest to the Everglades of Florida, throught the guts of a wastewater treatment plant and out to the waterways again. It shows how human-engineered dams, canals and farms replaces nature's beaver dams, prairie dog tunnels, and buffalo wallows. Step by step, Outwater makes clear what should have always been obvious: while engineering can depollute water, only ecologically interacting systems can create healthy waterways.Important reading for students of environmental studies, the heart of this history is a vision of our land and waterways as they once were, and a plan that can restore them to their former glory: a land of living streams, public lands with hundreds of millions of beaver-built wetlands, prairie dog towns that increase the amount of rainfall that percolates to the groundwater, and forests that feed their fallen trees to the sea.</Div>
