From the Don’t Mess With Mama Nature files: Stalin introduced giant Pacific crabs to the Barents Sea as a way to provide cheap and plentiful food for the Northwest Soviet Union. Everything seemed okay until some time in the nineties, when there was a huge population explosion. Now the voracious crustaceans are crawling South along the coast of Norway and eating everything in their path. Y’know, there could be a horror story in here somewhere.
(When I say that Stalin introduced the crabs to the Barents Sea, I don’t think he did it personally, “Giant Pacific Crab, meet the Barents Sea. Barents Sea, Giant Pacific Crab. I think you guys will get on swimmingly.”
I’m sure he had other people do it for him.)
