Environmental Health Perspectives Volume 113, Number 3, March 2005
Environmental Health Perspectives March 2005 The sheer enormity of the Great Lakes--which constitute about 21% of the Earth's surface freshwater--belies the fragility of its ecosystems, under constant assault from a wide range of pollutants and activities. The Focus (p. A164) and Spheres of Influence (p. A174) examine the environmental challenges facing this vital natural resource and the political challenges to preserving it for future generations.
