In the United States, wild boars do things that many people dare not think. They wreak havoc on American soil, destroying crops during the day, digging ancestral graves at night, and even destroying a fighter jet with the power of a single pig!
We have also seen a lot of wild boar-related news, but we have not yet encountered such a fierce one. What is the origin of these wild boars in the United States?
Super Pigs invaded the United States
First of all, we must understand that the world's pigs are roughly divided into domestic pigs and wild boars, and domestic pigs are domesticated by Eurasian wild boars and have a history of domestication for thousands of years; wild boars generally refer to untamed Eurasian wild boars.
For thousands of years, wild boars and domestic pigs were not completely isolated, and hybridization occurred between them. Under the continuous selection of genes, a new breed was born - super pigs.
There were no pigs in North America, and in the 16th century, the Spaniards who colonized Florida brought some pigs, but the numbers were small, and the pigs did not escape to other states.
At the end of the 20th century, there was an interest in hunting wild boars, and countless wild boar farms sprung up. Intentionally or unintentionally by the farmer, some wild boars escape into the wild and breed rapidly.
Wild boars have been raging in the United States for decades and have quickly stabilized their position. 6 million wild boars flooded 36 states in the United States, with only a few surviving.
The USDA conducted a study of pig populations between 1992 and 2012, and the results showed that if this rate of growth were followed, the entire territory of the United States would "fall" within 30-50 years.
In the United States, what "bad things" have super pigs done?
American super pigs are ambitious, not satisfied with eating, drinking and playing with mud, and many of their behaviors make people sigh "live for a long time".
In 1988, a wild boar was strolling around a military base in Florida when it suddenly caught an eye on an F-16 plane on the runway.
Without saying a word, the wild boar crashed head-on into the fighter, and the pig was fine, but the $20 million fighter was destroyed; the pilot recovered a life by ejection and was slightly injured.
In front of the plane, deeds such as arch vegetable fields are not on the line.
But that's not all, super pigs are no longer satisfied with only hoho people, and they have to do things at night. In the spring of 2013, a cemetery in rural Texas was destroyed by pigs, and the grass was overturned, and the scene was a mess. Fortunately for the misfortune, no tombstone was torn down.
However, the pigs are very arrogant, sleeping in the woods during the day and going to the cemetery at night to rummage through the soil to find insects to eat.
Super pigs are arrogant and make Americans head two big, and they are not only good at physical attacks, but also carry a huge threat to germs.
Each wild boar carries at least 30 species of diseases and 37 species of parasites, which may be transmitted to other animals and infect humans through multiple routes.
According to the U.S. Department of Agriculture, super pigs cause about $1.5 billion in losses in the country each year. The Americans were naturally upset about this, but despite their hunting and other measures, the number of wild boars was growing at an out-of-control rate.
Why is the "Super Pig" so cattle?
What is the ability of the super pig who hits the plane with his bare hands and makes the old beauty anxious? In fact, these hybrid pigs have both the ferocity of wild boars and the cleverness of domestic pigs.
Of course, one of their most notable features is their large size and thick skin. The average weight of super pigs can reach 300 kilograms, and in 2014, a teenager in the United States also killed a super pig with a length of more than 3 meters and a weight of 450 kilograms.
Thick skin is better understood, you know, wild boar is not instigated when encountering poisonous snakes, all rely on thick double fur as a physical defense.
While being large, the super pig also retains a good running speed, reaching a speed of 40-70 kilometers per hour.
If the number of slow growth, super pigs will not be so terrible, the hell is that they have a strong ability to reproduce. It is understood that a female wild boar has two litters a year, and a litter averages 4-12 piglets.
The average lifespan of wild boars is 10 years, up to 27 years, and a female wild boar can breed more than 100 piglets in a lifetime.
In addition, wild boars are not picky eaters, as long as they can eat everything, grass roots eat grass roots, crops can eat corn, potatoes, etc., so they can develop and grow rapidly. The economic losses caused by wild boars in the United States are also mostly crop losses.
Mainland man-pig conflict
The story of the American super pig is amazing, but it cannot be ignored that the mainland is also plagued by wild boars.
Wild boars have appeared in many parts of the country, which not only destroyed things but also injured people. In 2006, the number of wild boars in Zhejiang Province reached 100,000, and in 2020, the number of wild boars in Shaanxi Province also exceeded 100,000.
After the discovery of wild boars, ordinary people cannot kill them at will, because wild boars belong to the "three haves" protected animals on the mainland, and hunting and killing them privately may be suspected of violating the law.
However, proper control of the wild boar population is feasible. If you want to help, you can get a gun license, hunting license, and conditionally hunt the flood of wild boars after government approval.
The question is, what should I do with the wild boar that is killed? Foodies first calm down, because wild animals are easy to carry germs, the mainland has been completely forbidden to eat, so wild boar can not eat.
The wild boar obtained by legal hunting will generally be harmless treatment, disinfected with quicklime and buried in the pit on the spot; if the number is large, it will be processed by the professional department and made into animal feed for the beasts of prey in the zoo.
