How has federal protection helped Lake Superior?

The biggest of the Great Lakes and one of the largest freshwater ecosystems in the world — has remained relatively pristine compared to the other four. It’s far enough away from the populated urban centres in southern Ontario, its watersheds are largely forested, there’s little industry or agriculture on its shorelines and its especially cold water (an average of 4 C year-round) has kept away invasive species.
