WRONG FOR WILDLIFE
Should we mine beside an active volcano?
No. Science and history show that an open-pit mine in the foothills of Mount St. Helens (the most active volcano in the continental U.S.) will pollute clean water, poison wild fish, degrade habitat, and threaten the safety and prosperity of downstream communities.
