A new report says climate change could worsen a litany of problems plaguing the Great Lakes, from low water levels to depleted fish populations.
The report was released yesterday by the Healing Our Waters-Great Lakes Coalition, which represents more than 100 advocacy groups.
The U.S. Senate is preparing to debate global warming legislation next week, which coalition leaders say could generate funding for Great Lakes cleanup efforts.
But even if it passes, advocates say the lakes will absorb some effects of climate change. Lake levels could fall up to 3 feet and the waters may have more biological "dead zones" with no fish or plant life.
The report calls for repairing sewage treatment systems, restoring habitat and preventing new invasive species.
