Rats are a very widely distributed species on the earth. They are distributed in other parts of the world except Antarctica, and the population is very large. There are about 480 species of rats in the world. This kind of creature has strong survivability, can resist cold and heat, and has a very strong reproductive ability. So rats are not protected animals, there are only too many but not too few. At the same time, rats not only have a large population, but also have a great impact on human life.

Its footprints can be seen almost in sewers, toilets, kitchens, fields, grass, eaves, etc., and their destructive power is very strong, so in most cases, humans "hate rats" "It goes to the bone", hoping to completely eliminate it. However, after centuries of fighting, humans have not eliminated the rats, and the population has not changed much. According to the British dailystar scientific report, the British rat war has been completely defeated, and it is expected to become more serious in 2021. Britain was completely defeated in the war between humans and rats

According to British researchers, the UK was overrun with rats. During the war between humans and rats in the UK, some rats even mutated and turned into "super rats" ", they have extremely strong "antibody genes", and this mutation in mice is getting stronger and stronger. Practical data tests show that three-quarters of mice in the UK cannot be controlled, and sampling found that , 74% of mice already have "drug-resistant" genes, which means that some common "rat poisons" cannot kill them, so they have mutated into "antibody mice"

So pest control experts It is said that the UK will face a surge in rats in 2021. If there is no severe cold winter that affects rats, the number of rats in 2021 may increase even more dramatically, that is, the number will be larger, which is very worrying. As we mentioned above, 74% of mice carry genes that are resistant to popular rodenticides. In addition, 20% of mice have two different genes, so they are super resistant, so the war between humans and mice was completely defeated in the UK. The mice have undergone extremely strong changes and are also extremely resistant. How can we get rid of rats? Can they be completely eradicated?

In terms of the natural enemies of rats, there are cats, snakes, eagles, ferrets, humans, etc. However, it can be said that humans and rats have been fighting for centuries or even longer, but they still have not been eliminated. And the natural enemy species are now declining on a large scale, and the possibility of controlling rats is even lower. In this world, humans cannot eliminate rats, so there is no biological population that can eliminate rats. Therefore, it is basically impossible to completely eliminate rats. Moreover, rats are widely distributed and are really "pervasive". How to clean them up is too difficult. .

Nowadays, many people may have noticed that rats are no longer afraid of people. Even in the daytime, rats dare to pass in front of people, so they have indeed evolved and become more and more powerful. There is no doubt that rats are one of the toughest animals on the planet. In addition, they rely on cave protection and are timid and cautious, so it is not easy to hunt them. As we mentioned above, rats have super reproductive capabilities. They have a short gestation period and give birth to many litters. And you can continue mating and get pregnant on the second day after delivery.

How strong is this? They can reproduce several times a year, and each time they give birth to about ten offspring, the number of offspring will increase exponentially after that. Therefore, it is very difficult to eradicate rats. And as long as the eradication of rats in a certain area is slightly relieved, they will soon come back. . This may be the most difficult species for humans to eliminate. As climate changes and human influence intensifies around the world, most species are declining and disappearing. However, rats alone have not changed and have become more adaptable to survival. ability, so complete elimination is basically impossible. What would happen if all rats on earth became extinct?

First of all, we said that it is basically impossible for humans to exterminate all rats, but if all rats on the earth are really extinct, it will inevitably bring disaster, and every species on the earth will be "Intimately related", including us humans, we also said above that mice have many natural enemies. If the food of these natural enemies is gone, then these natural enemy species will inevitably face the possibility of population reduction, and it may be serious. Causing mass extinction of species.

So living things are "interlocked" and basically cannot escape the process of the food chain, and rats play a very important role in our lives. Some species will also be used with humans for experiments, research, etc., so if the mice are gone, it will be difficult for us to find replacements, because mice are a type of creature that can achieve good results in human experiments. So overall, without rats, the possibility of the ecosystem collapsing immediately is very high, and there has already been a situation on the earth where the extinction of a certain creature in a small area has led to a larger area of ??extinction.

So although rats are a kind of pest and have a great impact on humans, they play a very important role in the biological chain. However, after so many years of war between humans and rats, they still cannot reduce the rat population. This can only show that this species is really difficult to extinct, has strong adaptability and strong reproductive ability, which is difficult to compare with any other species. Therefore, maintaining balanced development of mice is still a scientifically difficult matter.
