Beasts of the Northern Wild

This is how a fishing village dies -- not, usually, in a wall of water, any more than a farming community dies in an earthquake:

 Now, the crab plant is long gone, every shop in town is shuttered and the population has plummeted to 72 from a one-time high of almost 800. Aside from a toddler and a pair of young teenagers, virtually the only islanders left are a few dozen widows and seniors, many of whom don’t have the money to leave.

And in reality it started with people going off to Halifax or Toronto "to work" and coming back, and going again and eventually not coming back. Once that starts happening, a place, no matter how hard to get to, really no longer is cut off from the outside world. And it has to take the consequences.
