Both bats and rats are harmful to humans, so why don t scientists find a way to exterminate them?

Any animal in nature has the inevitability of its survival, and the animal chain is interlocking and interdependent. Rats and bats are an important link in the earth's biological chain, and if the rodents are extinct, the eagles and snakes that feed on the rodents will also become extinct; Similarly, if bats become extinct, mosquitoes and other insect pests will proliferate, directly affecting the survival of humans and other animals, and will disrupt the balance of nature.

There is nothing wrong with not destroying them, people don't mess with them, there is no harm to people, and bats are still beneficial to people if they eat mosquitoes. Rats are harmful, fecundity, and difficult to kill. I also heard people say that it is called ecological balance.

They are also the ones who will contribute to humanity in the future. Flies are a big no-no-no for humans, but people extract the most powerful antibacterial substances from their injured bodies. A thing is born with the function of a thing, but it is not yet time!

Ecosystems, each organism has its own unique role, and the more singular the species, the more dangerous life is! Therefore, if it is extinguished, it will destroy the existing ecosystem; It will cause greater disasters to people, and then say that good and bad are relative, if anyone is harmful to us, we will destroy whom, maybe human beings will destroy themselves first, we are constantly destroying the natural environment, destroying the earth's ecosystem, we are constantly in internal strife, war!

According to biological theoretical knowledge, there is a food chain for the maintenance of ecosystems, rats and bats are members of the food chain, they have their own unique life values, how can humans exterminate them, although they are poisonous, but that is their characteristic, human beings do not need to provoke them, there is not so much right and wrong. At the same time, our current scientific understanding is insufficient, and the current methods of eating them are barbaric, low-level, and dangerous. It may be useful in the future.

In short, we human beings are also members of the ecosystem, and we cannot arbitrarily destroy the natural balance of the ecosystem, and nature has its evolutionary laws.

We humans have known an old saying since ancient times"Love and hate"This sentence. The human and animal kingdoms are supplied, harmful, loving, affectionate and hateful. Utilize each other and provide for each other.

Help each other and survive each other. From time immemorial, if you humans hurt animals, animals will hurt humans. This is what nature gives to humans and animals!

Ecological balance, this is the natural law in the process of natural development, whether it is rats, bats or flies and mosquitoes, their existence is of inevitable significance, if you think that the change will change the balance of the laws of nature, for example, flies do not have any benefit to humans, but if you eliminate the flies, who will decompose the garbage on the earth, and who will spread the bacteria.

Of course, it can't be allowed to develop freely, and if the ecological balance is broken, it will be a disaster, the golden toad in the United States, the crayfish in India, and the lobster in Australia are all natural disasters caused by their lack of natural enemies.

Because bats and rats are still very useful and useful, scientists don't want them to go extinct at this time.

Because these two animals are food for other animals, they cannot be killed casually for the sake of biological balance.

After repeated research, scientists have finally uncovered the secret of bats being able to fly at night. As it flies, it makes a sound from its mouth. This sound is called ultrasound, and it is inaudible to the human ear, but it can be heard by the bat ear.

The ultrasonic waves move forward like waves, and when they encounter obstacles, they reflect back and reach the ears of bats, which immediately change the direction of flight. Scientists imitated the method of bat pathfinding and equipped the plane with radar. The radar emits radio waves through the antenna, and when the radio waves encounter obstacles, they are reflected back and displayed on the phosphor screen.

From the fluorescent screen of the radar, the pilot can see whether there are any obstacles ahead, so the plane is very safe to fly at night. Bats are good at flying in the air, and can perform a variety of "aerobatics" such as circular turns, sudden braking, and rapid changes in flight speed. white dogs, hidden in caves, tree hollows, or gaps in eaves; At dusk and at night, fly in the air and hunt mosquitoes, flies, moths and other insects.

Bats prey on a large number of pests, which are beneficial to people and deserve protection.

Radar was invented.

Radar was invented based on the fact that bats can fly at night without using their eyes, and the bat can detect any obstacle that blocks it with ultrasound waves emitted by its ears and mouth, so that the exact location of these obstacles is displayed in the bat's brain, and the bat will not hit any obstacles. But on the contrary, if you plug the bat's ears and mouth, it will stumble like a headless fly. Radar is also the principle of bats emitting ultrasound waves, and they detect obstacles through ultrasound waves!

According to the principle of the bat ultrasound locator, people also imitated the "pathfinder" for the blind. This pathfinder is equipped with an ultrasonic emitter that a blind person can carry to spot people on electric poles, steps, bridges, etc. Today, "ultrasound glasses" with a similar effect have also been made.

radar and ultrasonic flaw detection, ultrasonic positioning, etc.

First of all, it must be pointed out that although bats and rats look somewhat alike, they are two fundamentally different animals (rats are rodents and bats are pterocods), and bats and rats are not to be confused.

Since rats don't do all the benefits to people, bats are different. At first, it is black and white, and most of the places where it inhabits are far away from people, and the key ingredients of bats (insectivorous bats) are insects, from the perspective of carnivorousness, bats can also help people get rid of insect pests, and then add that it does not actively touch people. Thus, bats are in fact a "beneficial animal".

We cannot exterminate bats because they are the hosts of viral infections and because people actively cause damage rather than touching them. This is also nonsense. Therefore, the bats are not **. What you can do is not to eat natural animals and not to hunt them.

Let's talk about rats. If rats are so hateful, why not exterminate them?

Rodent eradication has been carried out since the advent of humans, and to this day, rodent eradication has not ended. However, even in today's world of all kinds of special tools for rodent extermination, there is a reason why people cannot do the extinction of rats.

First of all, there is the total. Rats are the most widespread of all existing animals, and in China alone, there are more than four times the total number of rats. Such a huge number of rats is a difficult task after all.

The second is fertility. According to statistics, a 12-year-old female insect mouse can give birth to 8 times a year, and each time the average value will appear 5 up and down mice, in other words, a mouse can give birth to more than 40 offspring in a year, and the improvement of mice is rapid, a newborn mouse must only be about 3 months old to have the ability to conceive. This is the primary reason why the rat population can still be maintained under such extermination conditions.

Ultimately, it is a place to perch. If all rats were found in people's homes, it might be possible to exterminate them. However, rats that live next to people are only some of the many rats, and a very large part of them live in the wild.

This has become one of the biggest obstacles to rodent extermination.

In fact, from the perspective of the material cycle, rats are the specific food of many animals, such as weasels, snakes, magpies, etc., once the rats become extinct, the animals that feed on rats will inevitably suffer, which will jeopardize the balance of the entire environment.

Although the rat extermination has been in action, how can the rats have strong secrecy, strong reproductive ability, strong survival ability, large number, and large number of heads. This makes the extinction of rats a largely unlikely daily quest. I don't want to talk too much about bats, you know.

Because it takes a lot of money and a lot of time to get rid of them, and their existence has a unique meaning that can cause harm to the ecosystem.

Because these two animals can protect the integrity of the biological chain, these two animals have a relatively strong reproductive ability and play a particularly important role in the development and progress of society.

Bats and rats have many viruses that can cause a lot of harm to the body's immune function, and cannot be eliminated in order to maintain biological diversity.

Because once bats and rats are eradicated, it will cause ecological damage, it will lead to species disorder, and it may lead to species extinction.

Because although bats carry viruses, they are not useless to us humans, they can eat pests, mosquitoes and other pests, which solves a lot of problems for us, if there are no bats, our crops will be more damaged, and even there will be a reduction or shutdown.

First of all, the existence of bats has its meaning, if it is a member of the food, it will cause ecological imbalance, and secondly, it will also eradicate many pests for us and protect the growth of crops.

Because this animal can spread pollen, can prey on some harmful insects, and has some different places in itself, it is very valuable for research.

The extinction of rats will affect the population that feeds on rodents, and if owls and snakes can change their food structure after the extinction of rodents, they will feed on other animals or plants, which will inevitably affect or limit the development of other species that feed on them. If you can't change the structure of your food, you'll slowly or quickly become extinct.

There is a relatively balanced biological chain in nature, for example: the leaves and fruits grown by plants provide food for insects, insects become a food source for birds, with birds, there will be eagles and snakes, and with eagles and snakes, rodents will not become disasters......When animal droppings and carcasses are returned to the soil, microorganisms in the soil break them down into simple compounds that provide nutrients to the plant and cause it to grow new leaves and fruits. The biological chain establishes a healthy cycle of substances in nature.

Humanity has learned that the extinction of a population affects the health of the species associated with it and affects the next link. Although the impact is slow, it is real. In the end, it will definitely affect the survival and development of mankind itself.

According to the main content of this text, scientists have uncovered the reason why bats can fly at night through repeated experiments, and have been inspired by it to install radar on airplanes and solve the problem of safe flight of airplanes at night

1. What do people learn from bats?

2. How do bats find their way?

3. Why can an aircraft fly safely with radar?

There is no scientific basis for this statement, so I think it is wrong; Rats and bats had the same ancestor 200 million years ago, but rats and bats evolved from the same ancestor into two different states, probably because of the similarities between them, similar appearances, and both carry viruses that are harmful to humans, so people think that bats may have evolved from mice.

There is no scientific confirmation that bats evolved from mice, but in the past, people saw that bats resembled rats with wings, so there is such a theory.

There is no scientific basis for this, bats and rats are not related, and although they are very similar, they are not the same species.

There is no scientific basis for this statement, this is two completely different species, there is no similarity, it can only be said that the two have a common thread.
