Billions of snow crab are missing. A remote Alaskan village depends on the harvest to survive.

Some 330 people, most of them Indigenous, live in the village of St. Paul, about 800 miles west of Anchorage, where the local economy depends almost entirely on the commercial snow crab business. Over the last few years, 10 billion snow crabs have unexpectedly vanished from the Bering Sea. I was traveling there to find out what the villagers might do next.
