Document Summary
The film begins with a look at beluga whales in the st. lawrence river. Besides, it takes 350 years from water to get from l. superior to the ocean (about the same amount of time since european settlement began and also 7 generations). There is a shot of a native fisherman fishing from a boat. He takes a drink of water directly from the lake: hydroelectricity generated from rivers flowing into l. superior allowed to development and growth to take place there. Once example is pulp and paper an industry which uses water to make its product, along with bleach, inorganic chemicals, and other compounds, many of which are regulated. 90% are removed from waste water before it is discharged into rivers and the lake (that means 10% remains). The sioux rapids have been circumvented by locks for navigation this has allowed invasive species to move freely as well example zebra mussels, sea lamprey.
