In a landmark lawsuit, Minnesota is taking on 3M--the maker of Post-it notes, Scotch tape and other popular products--for polluting local waterways with PFCs, dangerous toxins connected to cancer and other afflictions.

Not surprisingly, the corporation has backpedaled on the pollution, claiming--contrary to scientific evidence--that the chemicals are "not hazardous." Yet locals have pegged the toxins as the source of  community health issues, and when the Minnesotan city of Lake Elmo recently finished drilling a new well in town, they discovered PFC levels in the water exceeded state standards.

Support Minnesota's landmark lawsuit by telling 3M the company to pay up for its polluting ways.
