Aquatic Light Pollution in Lake Superior

Not only does light pollution adversely affect land ecologies and species like ourselves, it also negatively effects the quality of aquatic habitat. 

GLEAM, or the Great Lakes Environmental Assessment and Mapping project produced this map, which I downloaded this week (December 18, 2012). It shows the amount of stress on the aquatic ecosystem due to light pollution - and it extends quite far up the shore.
