    Companies that own as-yet-unextracted fossil-fuel reserves could be left with stranded assets if the regulatory atmosphere changes, experts say. Expensive fossil-fuel sources, such as Alberta's oil sands, could be among the first to become uneconomic to extract. "I don't see this discussion going away. If anything, it's gaining momentum," says Ceres analyst Ryan Salmon.

Yale Environment 360 environmental news water Alaska Pebble Mine threatened

    The proposed Pebble Mine in southwestern Alaska is a project of almost unfathomable scale. The Pebble Limited Partnership intends to excavate a thick layer of ore - nearly a mile deep in places - containing an estimated 81 billion pounds of copper, 5.6 billion pounds of molybdenum, and 107 million ounces of gold. The mine would cover 28 square miles and require the construction of the world's largest earthen dam - 700 feet high and several miles long - to hold back a 10-square-mile containment pond filled with up to 2.5 billion tons of sulfide-laden mine waste. All this would be built not only in an active seismic region, but also in one of the most unspoiled and breathtaking places on the planet - the headwaters of Bristol Bay, home to the world's most productive salmon fishery. Composed of tundra plain, mountain ranges, hundreds of rivers, and thousands of lakes, the greater Bristol Bay region encompasses five national parks and wildlife refuges, and one of the largest state parks in the U.S.
