The animals are often crossbreeds that combine the survival skills of wild Eurasian boars with the size and high fertility of domestic swine to create a "super pig" that's spreading out of control.
An exploding population of hard-to-eradicate "super pigs" in Canada is threatening to spill south of the border, and northern states like Minnesota, North Dakota and Montana are taking steps to stop the invasion.
In Canada, the wild pigs roaming Alberta, Saskatchewan and Manitoba pose a new threat. They are often crossbreeds that combine the survival skills of wild Eurasian boars with the size and high fertility of domestic swine to create a "super pig" that's spreading out of control.
Ryan Brook, a professor at the University of Saskatchewan and one of Canada's leading authorities on the problem, calls feral swine, "the most invasive animal on the planet" and "an ecological train wreck."
There are huge swaths where you can't even tell where the border is. I've accidentally crossed into Canada multiple times while out hiking or canoeing.
Pretty sure it is actually just the longest international border in the world. I guess Chile and Argentina might be close, maybe Russia and somewhere, but USA Canada I reckon is the longest.
Land border: Canada's border with the United States is the world's longest international border, at 8,890 km. This compares with the 6,846-km boundary between Russia and Kazakhstan and the 5,308-km frontier between Chile and Argentina.
