The United States may soon have to deal with a threat from Canada. No, not their military. Not even spy balloons.

Super pigs.

That's right, for some reason, Canada decided to create gigantic “incredibly intelligent, highly elusive” pigs and let them roam wild across the countryside. What could go wrong?

The pigs were created by cross-breeding domestic pigs with wild boars imported from Europe. Farmers began doing this to raise the offspring for meat, and larger pigs meant more meat. However, the pigs soon got into the while, as many of the pigs escaped from farms. Others were purposely released into the wild because the demand for pig meat just wasn't high enough.

Since then, the pigs have been allowed to "breed uncontrolled for decades". And thus was born the mobs of Super Pigs, hurdling towards the United States border. According to The Guardian, "The wild pigs are also responsible for a laundry list of environmental damages, ranging from eating innocent farmers’ crops to destroying trees and polluting water. They also pose “a human health and safety risk."

So that sounds pretty bad. But wait, there's more! At least one Super Pig clocked in at 661 pounds, which makes it able to survive even the harshest Canadian winter. The "experts" originally thought it'd be no big deal if a Super Pig escaped into the wild because pigs can't survive the -50 C windchills of Canadian winters. But these are no average pigs. The Super Pigs tunnel up to 2 meters under the snow to create a "snow cave" and use their tusks to cut cattails to use as a warm insulation layer. Yes, they literally build themselves a little bed so they can live another day to wreak havoc on the ecosystem. Cunning little creatures, they are.

So is there any hope of eradicating this Super Pig problem? Not really - at least not in Canada. The Canadians have mainly been focused on managing the damage caused by the pigs as opposed to the 600-pound beasts themselves. And they've made themselves quite at home.
