Problems and issues confronting the Great Lakes system
The Great Lakes basin is a huge ecosystem. The specific problems in the Great Lakes have changed over time, but the broader issues have remained those of deteriorating water quality through industrial and municipal uses, fluctuating water levels, flooding, and shoreline erosion. Other concerns are acid rain, airborne toxics, depletion of wetland areas, increased demands on the shoreline land base, the impacts associated with the unintentional introduction of exotic species, and climate change.
