"As wild salmon populations decline globally, Bristol Bay's prolific wild salmon runs and the economies they support make it a place of international importance. It faces imminent threat from the proposed Pebble mine as well as hard rock mining on adjacent state and federal land. In order to stay thriving, the salmon must be protected from Pebble and other large-scale mining projects."
