Penokee Mine: Environmental Impact?


Other than converting 22,000 acres of natural area to an iron mine, what might be the environmental impact of a mine this big, at this location? Would there be harm to water, air, wildlife, and people outside the immediate area?


Many people are investigating these questions. Here are a few links and documents:
