The phrase "rats cross the street, everyone shouts and fights" is widely spread among the people, but if there are really no rats in the world, will there be no disease?
In order to eliminate this possible bias, let's start with the common rats and analyze the pros and cons of rat extinction.
Why rats are annoying.
Rats are a very annoying animal, in many provinces on the mainland, we all advocate the slogan of "rats cross the street, everyone shouts and fights", and the people have a great hatred for rats.
So why are rats rejected by everyone?
In fact, the main reason for rats is that they carry diseases, which is also a bit of a niche for the "extermination" of rats.
The reason why rats are infected with diseases is because they are not picky about their food, and even when some food is stored, because of some harmful substances in it, rats are stung.
When mice are injured, a large number of their organs will disintegrate, and most of the fragments of these organs cannot be digested by the mouse, so a very corrosive bacterium is produced.
These bacteria will pass through the digestive system of rats and then be excreted, and humans or poultry living in the same environment as them will of course be attacked by the harmful bacteria in these excrements and become sick.
And if there are some viruses in the feces of rats, then these viruses are more likely to spread immediately, because they can easily be blown away by the air and infect more things.
In addition, rats will also eat human food, money and other things, enter human dwellings, they will also bite off household appliances, wires and other things, so when rats come to human life, they can not be caught and killed, they will be affected by mice.
The great value of rats in modern society.
It is natural to think that rats are "pests" in life, but rats in modern human society actually have great value in many aspects, and even in some aspects, human "research" in this regard is limited to the mouths of the characters in the play.
In the 30s of the last century, scientists began to notice the striking similarity between mice and humans, so they launched a study on the similar characteristics of mice and humans.
Later, Francis Richter, a professor from the University of North Carolina, discovered stem cells from the "Japanese four-eyed hamster", so he launched further research, and finally he used this mouse to prove that stem cells are special and can differentiate the cells of organs, which can be described as earth-shattering news in the medical field, and has attracted great attention from all over the world.
This kind of mice were very expensive at that time, because they were greatly "rewarded" at that time, and the reproduction rate of such animals was very slow, so they were bred in large quantities at that time, so scientists found the "close relatives" of mice, so in the 40s of the 20th century, scientists began to use mice for medical experiments.
In the process of conducting research and treating human diseases, Truman asked researchers to correlate the results of studying mice with the "phenotype" of humans, thus "dismantling" the genetic rhizomes of these mice, which also laid a good foundation for genome research in the mainland.
In addition, rats also have a great role in environmental maintenance, when they eat food, they suck on the "details" of the food, and this detail directly causes the rats to eat very slowly, so for a long time, the food consumption of rats has been very limited.
The importance of rats in environmental maintenance.
They need to look for food for up to 4/5 of the time, which means that when they find toxic and harmful substances in the food, we humans still have a long time to "check" the food.
Moreover, because rats need a lot of time to find food, in this process, rats will be hunted by various predators, and this process can greatly help human beings to "cure rats".
In addition, because the lifespan of mice is very short, when they reproduce, they will quickly feed their "genetics", so they will spend a large part of their time growing and reproducing, and the born mice can mate and reproduce in a short time.
Therefore, when the number of rats exceeds a certain amount, there will be "cannibalism" and even "same-sex mating" between them, which can control the number of rats to a large extent, so that they will not be too numerous.
There was a very interesting incident in a foreign country, in order to control the number of mice in the city, so the cat was introduced into the city, and after a period of time, it was found that the number of mice was indeed well controlled, so these cats were caught, and after a while, there were more mice in the city.
This made people aware of the "law" of nature between cats and mice, so they paused the hunt for a while, so that the number of cats and mice was smoothly controlled.
Therefore, it can be seen that the position of rats in our human life is extremely important, but at the same time, rats also have part of the responsibility, that is, "infectious diseases", which make people hate rats very much, and in this regard, scientists have developed a lot of "means" for this, on whether to exterminate rats.
Non-substitution of rats in the biological field.
After people knew a lot about the coronavirus, there was a lot of interest in it, after all, the virus has a very big impact on people's lives, and people want to figure out where this virus came from.
Later, it was found from a foreign study that the virus was most likely transmitted from rats to humans.
In this study, scientists found a substance called "kinetic line virus" in the body of mice, which is a very harmful thing in human existence, scientists compared the genes of this virus with the genes of the new coronavirus, and finally found that the virus in the body of mice is very consistent with the DNA of the new coronavirus, and it is very likely that the virus in the mouse is transmitted to humans, and this will also bring great disadvantages to the survival of human beings.
After this incident, many people wanted to "crusade" against rats, and some people even thought that if there were no rats in the world, human beings would not have such a big disaster in terms of infectious diseases.
But this is actually a one-sided view, we can't just because of a certain reason, it has to be exterminated, the problem caused by rats is just a trivial matter, if the rats are really exterminated, it will bring great difficulties to the scientific research of human beings, because in addition to mice, we can not find other organisms to replace its importance in scientific research.
Therefore, if you really want to solve the problem caused by rats, you must analyze the root cause and solve the root problem of rats, and you can't get rid of rats because they can spread diseases and receive a lot of condemnation.
Rats may not be the "culprit".
On the mainland, there is a saying that rats are the 'culprits' of zoonotic diseases, but scientists are very skeptical of this claim, believing that this claim is very one-sided.
From a scientific point of view, humans and rats have nothing in common, and even what rats can eat cannot be eaten, so for humans, the habits of rats cannot be simply transferred to humans.
When humans feed animals, they don't feed rats to eat meat, so humans don't get sick from mice, but from humans to rats through trading activities and other means.
Epilogue:
When we manage rats, we can't just exterminate rats by solving problems, but we need to manage rats well, so that rats have something that can reflect their value in human society.
