Great Alaskan fishery faces crippling threat

The rivers of Bristol Bay make up the world's largest commercial sockeye salmon fishery and the bay accounts for $360 million annual income. After recently discovering the world's second-largest copper and gold resource at the river headwaters, a multinational mining corporation known as Pebble Limited Partnership (PLP) has applied for permits to develop one of the largest mines on the planet, an open-pit mine estimated at 55 square miles and producing several billion tons of toxic waste requiring treatment and storage in perpetuity.
