Book Description
Voices for the Watershed is a unique look at the singular and ecologically inter-connected region of the Great Lakes-St Lawrence watershed, including the headwater and upland regions. With contributions from experts from the United States, Quebec, and Ontario, this book offers an accessible introduction to the issues affecting the quality of our most essential and precious of natural resources - clean, fresh water - from headwater regions downstream to the Great lakes, the St Lawrence river, and ultimately the watershed's outflow to the sea. With thoughtful words and evocative photography, Voices for the Watershed promotes understanding and examines ecological problems, describing positive environmental actions and projects as well as ongoing concerns over the effects of pollution on wildlife and human health. The underlying themes throughout are that the drainage basins and ecosystems are under siege - from reckless land use decisions, soil erosion, acid rain, and massive habitat destruction - but that the situation is not hopeless. The authors feel strongly that education about the environmental threats - in the classroom and public forums - is essential to effecting positive change, and that conservation actions by citizen groups and individuals can be a driving force in effecting substantial reforms regarding environmental legislation and practices. Voices for the Watershed is an eye-opening look at not only the problems but possible solutions to help protect and preserve this resilient natural resource on which so many depend.
