Speaking of wild boars, I believe everyone is no stranger, wild boars have a very strong survivability, combat effectiveness "off the charts", some netizens have photographed wild boars across the Yangtze River, which actually shows that wild boars in nature survivability, adaptability is extremely strong, "Marshal Tianpeng" is indeed very powerful.
There is a saying that "one pig, two bears and three tigers", here it is the ferocity of wild boars, their limbs are very strong and powerful, their bodies are covered with hard bristles, plus they often rub against the trunk of trees, so their skin is very hard, it can be said that the skin is rough and thick, and they are not afraid of natural predators.
As an omnivorous animal, wild boars are not picky eaters, they can eat plant leaves, flowers, fruits and even tree roots, of course, they can also eat all kinds of small animals, as long as they can eat it, they are not taboo.
In addition, the reproductive capacity of wild boars is also quite amazing, they can give birth to 1-2 litters per year, and each litter can give birth to up to a dozen or so cubs, and the survival rate of these cubs is also very high, reaching more than 90%. Since wild boars can reproduce when they reach the age of 1, and their lifespan is about 20 years, a female wild boar can theoretically reproduce hundreds of offspring in her lifetime.
It can be seen that how strong the survival ability and reproductive ability of wild boars are, it is easy to flood. In the United States, there is even a kind of miscellaneous wild boar that is stronger, more fierce and more destructive than wild boars, known as "super pigs", which are not only rampant in the United States, but also in Canada.
"Man-pig war" for more than 30 years
This kind of super pig combines the survival skills of wild Eurasian wild boars with the size of domestic pigs, that is to say, the reproductive ability and survival ability of super pigs have been "strengthened", a female super pig can give birth to 2 litters per year, each litter can give birth to 6 piglets, and can give birth to 12 piglets per year.
Like wild boars, these super pigs are not picky eaters, they eat everything, whether it is crops or wild animals, they eat everything, even if the winter in some parts of Canada is extremely cold, these super pigs are not afraid, in such a harsh environment, super pigs can still survive well.
Although they are pigs, they are not as stupid as we think, on the contrary, they are smart and vigilant, and can easily spot danger approaching. Therefore, these "super pigs" have strong defenses, are difficult to hunt, and are called "the most invasive animals on the planet" by some experts, and it is impossible to completely eradicate these super pigs.
If it is a general invasive animal, humans may still have a way to deal with it, but in the face of these super pigs, the United States and Canada are also powerless, even if the "human-pig war" lasted for 30 years, but the United States finally lost.
Because these super pigs are so fertile and adaptable, if there is no way to kill them all at once, if there is a super pig in the wild, then it may breed a large number of super pigs, and the population size will easily grow. Super pigs have now been found in at least 35 states in the United States, and their total number has reached about 6 million.
These super pigs are ferocious and destructive, causing great damage to Canada and the United States, including as much as $2.5 billion in economic losses to the United States, and even once launched attacks on humans.
Where did the super pig come from?
How did the super pigs come to be so destructive? Why didn't the locals take measures to eradicate them when the numbers were relatively small at the beginning? If the super pigs had just started to appear, they should have been able to eliminate the super pigs at the source.
According to related reports, super pigs did not exist originally, and in the 80s of the last century, Canada encouraged farmers to raise wild boars. At that time, some farmers crossed wild boars with domestic pigs, and super pigs appeared, which combined the survival skills of wild Eurasian wild boars with the size of domestic pigs, and their survivability and reproductive ability were quite amazing.
At the beginning, super pigs were not yet overflowing, because at that time, hybrid super pigs were mainly put on the market for sale, and their survival and reproduction were still controlled, so they did not flood. When the market collapsed, some farmers released some of the super pigs into the wild, intending to leave them to fend for themselves in the harsh Canadian winters, so they ignored them.
It turns out that humans still underestimate the viability of these super pigs, even though the winter in Canada is very cold, but these super pigs still survive well, and quickly reproduce, and eventually there is a flood of super pigs in Canada.
After the infestation of super pigs was discovered in Canada, the relevant authorities also took measures to control it, but it was too late. Canada shares a border with the United States, and some super pigs crossed the border from Canada to the United States, and eventually the super pigs also invaded the United States, and the United States also flooded.
