I've never met a snow crab, but I've met snow crab fishermen. Not too many years ago I used to regularly dine in a small mom and pop restaurant in the Detroit suburbs that offered all you could eat, steamed snow crab legs with drawn butter at a bargain price.

In fact, snow crabs have long been seafood staples at ordinary American restaurants.

Until recently, eating snow crabs was considered environmentally okay, because our annual harvest in Alaska wasn't harming populations.

Now that those crabs have picked up and packed their bags or, more likely, died, an entire industry is out of work. The seasonal snow crab harvest used to be a pretty good cash opportunity for Alaska fishermen, many of whom are poor people working seasonally.

That's all over now.

Maybe when enough people start losing jobs, they'll stop denying that climate change is really happening. Or not.
