Anglo-American mining plans threaten millions of salmon

29 July 2013 Last updated at 20:37 BST

The landscape of Alaska is where a massive dispute between the fishing and mining industries is escalating.

The issue has divided opinion in the US's largest state and prompted warnings that one of the last great wild fisheries in the world is at risk.

Britain's Anglo American and Canadian partner Northern Dynasty are pushing to develop a vast open cast copper mine, the largest ever in North America, in the headwaters of Bristol Bay, south west Alaska.

Every summer 40 million wild salmon swim in to the bay before heading up the rivers and streams of the region to spawn and die.

HARDtalk's Stephen Sackur reports from Alaska.
