Feral hogs already unleash economic damages of about $1.5 billion a year in the United States, and with this imminent gift from our Canadian neighbors, that toll's growth is set to accelerate. The pigs bring destruction in a variety of ways: devouring crops, uprooting trees, contaminating water, and carrying viruses that can leap into human populations. Typically three feet tall and five feet long, "these pigs are easily the worst invasive large mammal on the planet," the University of Saskatchewan's Ryan Brook tells Fox News. However, the brainy beasts -- whose DNA goes back to Siberia -- quickly figured out how to make deep snow caves, even lining the bottoms with cattails scythed with their sharp tusks. "They’re so warm inside that one of the ways we use to find these pigs is to fly first thing in the morning when it’s really cold, colder than -30, and you will actually see steam just pouring out the top of the snow,” Brook told The Guardian. https://www.zerohedge.com/markets/canadian-super-pigs-about-invade-us-and-unleash-major-damage
