Pollution rating rude awakening

The pollution ratings from the Sierra Legal defense Fund, focusing mainly on the poulltion of the Great Lakes in Canada and America. London, Canada got a pathetic C+ but they faired better then cities right here in the United States. Cleveland pulled out a D+ and Detroit managed a D. Although we had some bad cities, their are cities that are actually doing the right thing. Green Bay was at the top of the list with a B+ rating and and Dulith, Minnesota pulled out a B rating. The study found about 90 billion liters of untreated water enters the Great Lakes every year through both storm- and sanitary- sewer overflows. The irony in this is that a lot of people use the same lakes from which we get our drinking water as a toilet. London actually gets its drinking water from both lakes Erie and Huron. Billions of gallons of untreated urban sewage and toxic fluids are finding their way into the lakes each year, threatening fragile ecosystems and risking the water we all drink. Both the Canadian government and the United States government need to come together on this issue and try and resolve it. If we don't stop pollution we aren't going to get anywhere. I mean Detroit got a D rating, that's just pitiful. The government should be doing a lot more to help our cities out, a D and a D+ is just horrible. This just goes to show how much the government really cares about pollution.
