If there is no oxygen on Earth for 5 seconds, what will happen to humanity?

The earth is the mother of all human beings, and it is also the most special existence in the universe of science and technology, because of the existence of living beingsAnd one of the big reasons is that there is enough oxygen to form a good ecosystem, so some people ask if there is no oxygen on the earth for 5 seconds, what kind of disaster will human beings encounter? It is estimated that it will affect many aspects, and even for many elderly people, it is a life-threatening situation, let's analyze it.

First of all, human beings need to breathe every day, which inhales oxygen, exhales carbon dioxide, and carbon dioxide will be absorbed by plants, and re-decompose to obtain oxygen, so as to ensure a balance of the ecosystem, and oxygen for human beings can indeed temporarily cover their noses and stop breathing for a few seconds, but if it exceeds 15 seconds or so, the problem of suffocation will occur, so for ordinary people, there will be no problem without oxygen on the earth for 5 seconds, but it will affect many aspects, because people need to work, Without oxygen, there is no activation of the body system, and naturally it will be affected a lot.

For the elderly, the body system organs have weakened a lot, at this time there is no oxygen for five minutes, for them is a serious life crisis, if not solved as soon as possible, it is completely likely to lead to death, this is only the earth stopped 5 seconds of oxygen **, it can be seen that the importance of oxygen for people's lives, but also a key point in the search for the second planet, but also to tell you about the second planet.

Scientists have found that although there are a lot of resources on the earth, but the speed of human consumption is too fast, coupled with the destruction of the environment and other reasons, it is too difficult to regenerate these resources, so they began to look for a second planet suitable for human habitation, Mars is currently one of the targets, the oxygen content is almost similar to that of the earth, but still no water resources have been found, can not be used as a second planet, and other targets have no oxygen, let alone moved over.

will die. If there is no oxygen in an instant, human beings are in a vacuum, and the pressure brought by the atmosphere will squeeze human beings to death.

It will cause chaos in the biological chain, and many organisms will die after 5 seconds of oxygen shortage, which will have a great impact on the existing biological chain.

The ozone layer is unable to withstand harmful light and can prick us**.

The sky is blue because of oxygen, and if there is no oxygen for 5 seconds, the sky is black.

Oxygen is not the most abundant gas in the atmosphere (nitrogen is the most abundant), but oxygen is the most important. You might think that five seconds is nothing, because humans don't die even if they hold their breath for five seconds. However, in reality, if the entire planet were to lose oxygen for five seconds, humanity would face a devastating catastrophe.

Without oxygen, we will lose about 21% of our air pressure <> instantaneously

force, which is similar to jumping into the ocean floor at a depth of almost 2000 meters. This causes the eardrum to not adapt to the pressure, leading to barotrauma (a condition in which the pressure inside the ear is not equal to the pressure in the surrounding environment). Barotrauma is usually caused by a sudden change in air pressure.

For example, if you are diving in the deep sea or traveling in the air, you will feel that your eardrum is swollen and painful. Without oxygen, we all suffer from barotrauma, and it's drastic – the eardrum might**. As a result, hearing will be severely damaged.

If we humans want to live a healthy and normal life on the earth, there are certain requirements for oxygen concentration, that is, it must be less than 35%, and if it reaches 40%, then our body will definitely be damaged to a certain extent, such as the respiratory tract and lungs. <>

Of course, in addition to the permanent damage to our human body, it will also cause great damage to many other animals in nature, the concentration of oxygen continues to rise, most of the land animals may slowly appear after absorbing this high concentration of oxygen, and the body organs may be damaged, resulting in the continuous death of animals, and the number of animals is decreasing and showing a gradual extinction trend.

In addition to these aspects, in fact, the oxygen concentration content is too high, which will also cause the oxygen in our ocean to continue to rise, and if the oxygen concentration in the ocean is too high, of course, it will affect the marine ecosystem, and all kinds of marine life in the ocean, of course, will face the danger of extinction. <>

This may seem terrible, but the impact is much more than that.

If this happens, then all life on Earth will live normally, after all, it is only a temporary effect.

It's nothing, after all, people can basically hold their breath for 2 minutes, and suddenly disappear for a minute without stress.

If the oxygen is gone for a minute, most of the mammals will probably die. Because mammals live on oxygen, they will suffocate without oxygen, even humans.

Most creatures die. Many animals, including humans, struggle to survive a minute of hypoxia, and only those who have been trained to survive.

Oxygen is the source of life on the earth, without oxygen, there would be no plants, animals and water on the earth, and even humans would not be able to survive, because oxygen is the main catalyst for the intracellular energy necessary to maintain human life, and the oxygen that we breathe depends on for survival accounts for about 21 of the atmosphere, of which 78 is nitrogen, and there is also 1 carbon dioxide and other gases. Although oxygen is not the most abundant gas in the atmosphere, it is also the most important not only for humans but also for plants and other living things.

But what happens if the Earth suddenly loses oxygen for 5 seconds? Can humans survive holding their breath?

5 seconds seems very short, it is over with the eyes closed and the eyes open, both humans and animals can hold their breath on their own, people can generally hold their breath for 30 to 40 seconds, and some people can even last for 1 minute, but it is impossible to go without breathing all the time. But if the Earth suddenly loses oxygen for 5 seconds, the world will look completely different.

The first is the impact on human beings, usually in summer will feel too hot and too sunny, but basking in the sun for 5 seconds will not have much effect, but the earth will lose oxygen for 5 seconds is different, the earth will be an extremely dangerous living environment. If you are in the sun at this time, you may suffer a severe sunburn, because the ozone layer is made of oxygen, which is the protective layer of the earth, and without oxygen, the ozone layer will also disappear, so the earth will be exposed to ultraviolet rays. The inner ear will also explode, because the air pressure on the earth will drop by 21, which is equivalent to diving to a depth of 2,000 meters in 5 seconds, and the sudden change in air pressure is something that the ear does not have time to adapt.

The second is the impact on buildings, in just 5 seconds the earth is deprived of oxygen, and the houses, dams, high-rise buildings, and anything we build made of concrete will collapse instantly. Because oxygen is a special binder for concrete, without oxygen, concrete is dust, and it will collapse instantly without wind, which is comparable to a tofu slag project.

First, it will lead to the extinction of many species in the world. Even some flowers and trees will die in an instant. Second, it can also cause asphyxia in human newborns. Or even brain death.

First of all, without oxygen, the combustion process of the engine cannot be carried out, all the oil-burning cars will immediately turn off, causing traffic paralysis, and airplanes will fall from the sky, and secondly, oxygen is a special binder for concrete, and large buildings made of concrete will collapse immediately, and after losing oxygen, the ozone layer will disappear, and the atmosphere will lose 21% of its air pressure in an instant, and people will not be suffocated to death, but.

It may lead to the mass extinction of many animals, because oxygen is one of the basic conditions for many animals to survive, and if there is no oxygen for 5 seconds, these animals will die of lack of oxygen.

At this time, people and animals on land will have difficulty breathing, and there will be a feeling of suffocation, and elderly people and animals will immediately die on the spot.
