Near my home in Utah, Rio Tinto's massive Bingham Canyon Mine is one of the biggest man-made excavations on Earth and has rendered a large area of local groundwater too polluted for human consumption.
Now, the Rio Tinto and Anglo American companies want to put a mine even bigger than Bingham at the headwaters of our planet's greatest wild salmon river systems in Bristol Bay, Alaska. It's an environmental tragedy waiting to happen.
Their Pebble Mine would be gouged out of an American paradise -- filled with salmon, bears, moose, caribou, wolves and whales -- that has sustained Native communities for thousands of years.
