In Nova Scotia, a dispute between fishermen and a pulp mill escalates with a stand-off at sea

Across from the fishing pier in Pictou, Nova Scotia, smokestacks pump out billowing clouds of white smoke that drift over the choppy water. The Northern Pulp mill sits on one side of the harbor, churning out pulp that's used to make toilet paper and paper towels. On the other, fishermen who make a living catching lobster, crab, herring, and mackerel tie up their boats.
