Minnesota is home to the headwaters of the three major North American watersheds that drain north to Hudson Bay, south down the Mississippi River to the Gulf of Mexico, and east out the Great Lakes and St. Lawrence River to the North Atlantic Ocean. Slicing across all three watersheds are two black Enbridge tar sands oil pipelines from North Dakota to Superior, Wisconsin. The southern pipeline is the new “replacement” Line 3 that would carry more than 31-million gallons of oil daily, with a huge dump of carbon emissions into the earth’s atmosphere.
