China breeding polar bear-sized pigs
Polar-bear-sized pigs now being raised in Guangxi
Because we clearly didn't have enough to fear already, Chinese farmers are breeding 500-kilo pigs.
This is a clickbait headline, obvs, and you're supposed to be afraid when you read it, but the more sober reality isn't all that much better. Swine flu has decimated Chinese hog herds, and pork is popular enough that they need to make up the difference.
Now we just need Babe the Blue Ox size cattle.
