Pigs are not actually native to the Americas. Animal dispersal causes more damage. Now there is a big problem.
Fears of the spread of the Canadian pig breed to North America are growing. The so-called “superpigs” are considered “incredibly intelligent” and difficult to tame, writes “The Guardian”. The animals survive the cold weather by boring through the snow. They are spreading further in the north of the continent.
Developed by farmers in the 1980s, the super pig, a cross between domestic and wild pigs, is larger and produces more meat, the report says. Its size also helps it withstand the cold of western Canada, which can drop to -50 degrees.

Its proliferation adds to the problems America is currently facing with swine fever. The animals are not native there, but about 6 million wild boars have caused damage worth US$1.5 billion (about €1.4 billion) in recent years.
Pigs are food competition for native animal species, killing young chicks, for example, and endangering turkeys and quail as nest robbers, explains Michael Marlowe of the U.S. Department of Agriculture’s “The Guardian.” In addition, pigs can transmit viruses to humans, for example, creating new types of flu viruses that can be transmitted to humans.
