Yet another poorly-reasoned, poorly-researched sob story from the New York Times

Despite Mild Winter and Few Hunters, Seal Pups Face Threats - NYTimes.com

In Port au Choix, Newfoundland, and other communities around the gulf, hundreds of desperate harp seals arrived in late winter to give birth on fragments of ice clinging to the shoreline. Then, a few weeks ago, seal pups born elsewhere began floating in on small, shrinking pieces of ice.

“We haven’t seen any seals around the shore here anywhere,” said Robert Courtney, the president of the North of Smokey-Inverness South Fishermen’s Association in Cape Breton, Nova Scotia. “I think they went to the north, 300 miles from where we are. It’s too far.”

The Canadian government counts 6.9 million harp seals in the Gulf of St. Lawrence herd. In a normal year, they would produce about 280,000 pups.

The Northwest Atlantic harp seal population is now estimated to be approximately 5.6 million animals, nearly triple what it was in the 1970s.
