If you’ve ever savored the flavor of wild Alaska salmon, there’s a very good chance that salmon came from southwestern Alaska’s Bristol Bay, where the cold, clean waters of the eastern Bering Sea generate the largest sockeye salmon run in the world.

If you’re a fan of this fish, it might come as a surprise, then, to learn that the world’s largest wild salmon runs are at serious risk.

Despite its status as a world-renowned fishing ground, Bristol Bay has recently come under threat from off-shore drilling and mining proposals.
