For centuries, narwhals and ringed seals have provided food for Inuit communities on the ice floes of Mittimatalik, or Pond Inlet, on northern Canada’s Baffin Island. But now, the Inuit – who have hunted, trapped and fished in the region since long before the Hudson Bay Company opened its first Arctic trading camp here in 1921 – say they no longer find the narwhals where they should be. They say shipping noise is to blame.
