A study due out today by the Sierra Legal Defense Fund today grades various municipalities who live on the Great Lakes for their collection, treatment and disposal of sewage.  The results were abysmal.  Some 90 billion liters of raw sewage is pumped into the Great Lakes basin every year.  Untreated effluent is, as this article on the report notes, is more than merely what is flushed down our toilets or poured down our drains.  It ”is a foul cocktail of human waste, micro-organisms, disease-causing pathogens and hundreds of highly toxic chemicals.”  Other recent studies have found trace levels of antibiotics and the chemicals used in the birth control pills in Lake Ontario.

 
The obvious problem is that the Great Lakes also supply drinking water to the millions of people who live on the shores of its lakes.  Similar to the global warming issue, or perhaps much more grave in terms of the direct health implications that polluted drinking water presents, we cannot continue to tamper recklessly with the delicate ecosystems that supply life for us on this planet without it catching up to us as a species.
