preface
Don't be too surprised if you walk the streets of Japan and find wild boars rampaging everywhere, because today's wild boars in Japan are not enough.
The wild boar species has become so widespread in Japan that a new class called bounty hunter has even been born in order to capture them.
But why would locals rather shell out millions of prizes and hire hunters to catch them than eat wild boars?
Only dare to grab and dare not eat
In March 2011, an earthquake and tsunami struck the Fukushima region of Japan, and human error led to the destruction of the Fukushima nuclear power plant, followed by the highest level of nuclear leakage.
As soon as the incident occurred, a large number of radioactive materials began to spread in the air, and the surrounding environment was completely exposed to radioactive pollution, in order to ensure the safety of personnel, the government immediately arranged for personnel to evacuate.
After all the personnel were evacuated, the area of the nuclear leak became a no-man's land, and because of the rush to leave, the pigs raised by the staff remained here.
This gave wild boars the opportunity to live unbridled here, mating with the island's domestic pigs and producing a large number of offspring.
By 2018, the number of these wild boars had reached 60,000, and this number continued to increase, which can be called a flood.
When these wild boars reach a certain level, the competition within the population will become more serious, and in order to better survive, they will begin to move towards the city.
So everywhere in Japan, you can see a herd of wild boars rushing by, breaking into residents' homes to eat, and turning over roadside garbage cans.
If you go forward and drive them at this time, you will see a group of wild boars rushing towards you at a very fast speed, they will not have any damage, but they will pose a threat to your life.
In addition, scientists have studied local mutant wild boars and found that their genes have also changed, and the living habits of these wild boars have also changed greatly.
It is itself a nocturnal animal, but now the new breed hybridized is haunted during the day, and the mental state during the day is much better than at night.
Moreover, these wild boars never hide their whereabouts, and they appear in front of people's eyes, as long as they find a threat, regardless of the three seven twenty-one, they will come forward to attack, causing a very serious personal threat to the surrounding residents.
In order to protect the safety of residents, the Japanese government had to organize personnel to hunt, which evolved a new profession, bounty hunter, killing an adult wild boar can get a bonus of 16,000 yen.
Looking at this large bonus, many people voluntarily joined the hunter industry, and some even quit their original jobs to concentrate on catching pigs, and finally made a lot of money from this industry.
In fact, it is very strange that Japan only dares to send people to catch wild boars, and after catching them, they are directly killed, and no one has ever thought of eating them.
To this question, scientists made a reasonable response, they specifically captured wild boars for research, and found a large amount of radioactive substances in the body of wild boars, which are very damaging to the human body.
This also causes wild boars to lose their edible value, and after hunters capture them, in order not to pollute the environment, they can only bury them on the spot.
In fact, wild boar in Japan has always existed, but it has never been as widespread as it is now, so why did these wild boars suddenly increase?
Wild boar in Japan is rampant
There are probably three factors in the flooding of wild boars in Japan, the most obvious one is the rapid reproduction rate of wild boars, an adult sow, will breed twice a year, can have seven or eight piglets at a time.
In addition, wild boars, a creature, have no natural enemies in the natural environment, do not have high requirements for food, can eat anything, eat anything can survive, so the growth of wild boars is relatively smooth.
In fact, wild boars are still relatively intelligent animals, and after knowing that the natural environment will affect their own development, they gradually attack the city.
Wild boars growing in the natural environment will be more afraid of people, and their combat effectiveness is not particularly strong, but wild boars affected by nuclear radiation have completely subverted people's cognition of wild boars.
Genetically mutated wild boars are not only not afraid of people, but also can actively attack humans, coupled with the influence of radioactive substances, the combat effectiveness of these wild boars cannot be underestimated.
An adult wild boar can easily destroy a wall while running at a rapid pace, and if the target is replaced by a human, the consequences can be imagined.
And wild boars are not very stable, very easy to get angry, their favorite thing to do is to run around in the bushes, when they feel disturbed, they will get angry and suddenly attack.
This also caused bounty hunters to dare not easily confront wild boars, and most of their methods of catching wild boars were to set traps in places where wild boars were frequented and wait for pigs.
In fact, bounty hunters can have huge profits, but also because the combat power of wild boars is amazing, and in the process of fighting between the two, humans are easily injured, and in severe cases, they will lose their lives.
But even in such a situation, there are still many people who are willing to take risks, and some even become millionaires in this industry alone.
In fact, to some extent, the large number of wild boars entering the city is also related to the behavior of humans themselves, human beings are kind by nature, and they want to help when they see weak creatures on the road.
Newborn wild boar pups are cute, walking on the side of the road will attract people who are overflowing with compassion, and many people will specifically find food to feed them, how can a wild boar who tastes the sweetness pass up this excellent opportunity.
So after returning home, he told the other wild boars that everyone entered the city together to seek better development.
The wild boars who came to the city found that there was no one to feed them, and many people were afraid of them, but humans did not dare to attack them easily, so the wild boars were more unscrupulous, doing whatever they wanted on the streets, and finally brought a crisis to the Japanese.
However, in the development of human history, every social stage will face the problem of the flooding of a single species, some of which are actively introduced by humans, and some are maliciously released by other countries.
But in any case, humans are also experienced in this kind of problem, so how should we solve the overproduction of a single species?
Addressing monospecies overbreeding
Everyone should be familiar with crayfish, it is a food that is in short supply in summer food stalls, but few people know that crayfish were brought to China by the Japanese.
Crayfish are native to North America, and were first introduced to Japan as feed for bullfrogs, but the reproduction rate of crayfish exceeded Japanese expectations.
In desperation, they had to introduce crayfish to the mainland, and for Chinese, crayfish is a very delicious food, and Chinese chefs make ugly-looking crayfish into food of various flavors.
This move surprised the Japanese, Chinese How dare they eat anything? Conversely Chinese confused by Japan's behavior, how can you let crayfish flood if you eat them?
This is because China and Japan have different environments, there are many nuclear reaction bases in Japan, and the sewage from the factory will be directly released into the water, so the crayfish contain radioactive substances in their bodies.
This is the same as the wild boar that is rampant in Japan, because of genetic mutations caused by nuclear radiation, so Japan can do nothing about this situation.
In fact, in order to resist invasive alien species, there are many effective prevention and control measures in the mainland, the first is artificial control, relying on artificial power to capture alien species or actively remove these species.
But this method is only suitable for invasive species that have just invaded and have not yet spread widely.
So in order to better solve this matter, the mainland proposed mechanical removal measures, using specially designed and manufactured mechanical equipment to control harmful plants, reduce their development speed, in order to obtain more time to solve the problem.
However, for China, the most effective is alternative control, which mainly targets exotic plants, and the staff will take into account the succession of the plant community itself, and look for native plants with economic or ecological value.
Using them to replace the role of invasive alien plants, and even from the origin of alien pests, natural enemies with relatively single diets will be introduced, and with their help, the population density of pests will be controlled at a level that does not harm ecological development.
Then again, Japan's wild boar behavior is indeed very disgusting, but the impact of this incident is also worth reflecting, to put it bluntly, this incident itself is a human mistake.
If there were no nuclear power plants in Fukushima, even if there were an earthquake and tsunami, there would not be much radioactive material, and even if these nuclear power plants existed, the wild boars in the mountains would not have mutated if Japan had not discharged untreated contaminated water into nearby water sources.
Human beings are not the masters of nature, we need to live with other creatures, if we violate the laws of nature, we will be punished by nature, and once the ecological environment is destroyed, it will be irreparable.
epilogue
The world's ecological environment is in a relatively balanced state, which is stable and stable, but it is still inevitable that a certain species will develop rapidly.
This widespread phenomenon of wild animals is a huge test for us to deal with the relationship between people and wildlife.
In resolving the contradiction between the two, it is necessary to rely on the thinking of the rule of law and use scientific means to solve the problem of the proliferation of wild animals, which is an important starting point for promoting the national governance system.
In daily life, countries still pay attention to the protection of the natural environment, just as Japan discharges sewage containing radioactive substances directly into water sources.
Wouldn't it be worth the loss that the inhabitants and other living things would be affected, and even affect the development of the country?
After reading this article, please pay attention + comment, so that you can quickly pay attention to new developments in subsequent events
