Great Lakes Protection

The Great Lakes hold 1/5th of the world's fresh surface water supply and currently provide drinking water to over 42 million people. The health of these lakes is critical. The Great Lakes Campaign works to address the concerns related to the Great Lakes Basin, water conservation, and pollution prevention. 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, and industrial residues in sewage effluent. These problems lead to a host of negative impacts such as the introduction of invasive species, habitat loss, increased demands on the shoreline land base, and the discovery that flame-retardants leaking from computers and mattresses are building up rapidly in the tissues of many animals living in the lakes. 

Sierra Club Ontario works together with Sierra Club Michigan Chapter in the States, and collaboratively with other regional partners to implement solutions dedicated to restoring and protecting the health of the Great Lakes.
