What would happen to humans if the Earth s temperature continued to be minus 30?

If the earth is at minus 30 degrees for a long time, not only human beings will go to extinction, but also the life on the earth will eventually perish, because the ecological chain of the entire earth is fixed, and the loss of any link will trigger "dominoes."

Chain reaction. <>

At the beginning of minus 30 degrees Celsius, the plants on Earth are first declared extinct, which in turn triggers herbivores.

Following the extinction, even if there are some animals that live underground and can rely on the earth to keep warm, but there is no food for a long time, the result is the same. Although human beings have more developed scientific and technological conditions and can build underground cities, any technology that is divorced from agricultural production cannot continue, because diet will always be the basic need of human beings.

Initially, humans were able to survive by relying on food reserves, but when the food was exhausted, they would sit back and wait until there was an "artificial sun" to supply the food cycle to grow. However, when the world is getting colder, it is impossible to create large-scale fields underground, and without sunlight, there will be no decomposition of microorganisms, and food will not be able to obtain the nutrients needed for growth, and most people will disappear because of food.

Probably many people will say that by eating marine life.

Sustaining life, but marine life is also part of the natural cycle chain, "Big fish eat small fish."

Xiaoyu eats shrimp" only said one link, algae for small fish to eat.

Aquatic plants are no longer there because of low temperatures, and it is certain that the big fish will eventually disappear, so this idea does not work.

In order to heat up, human energy consumption will increase, and more efficient and more extensive energy sources will be sought. Summer Olympics.

and so on summer sports disappear, the Winter Olympics.

and other games will rise. Although there is no problem with basic life, the long-term effects of environmental change will inevitably change the function and even structure of the human body, early on the tropics.

The crowd will have an impact and may even eliminate some people whose physical condition and living conditions are not suitable.

As the human body slowly adapts to the environment and produces some new functions, such as enhancing the warmth of fat, human beings will live and reproduce well at a new equilibrium. In short, if the earth is really minus 30 degrees Celsius for a long time, all living things will definitely perish.

Human beings will lose their healthy health, and secondly, they will not have a good living environment, which may make great changes in people's lives and lives.

The life span of human beings will be shortened, and this time will also affect the normal activities of human beings, and the most important thing is that most people have no way to continue to survive in this situation, so they can only stay at home every day to keep warm.

In this way, human beings will definitely not be able to survive, and it will make the body become very cold, and eventually they will freeze to death.

When the Earth's temperature reaches 60 degrees, it is unsuitable for human habitation. The limit of what human beings can withstand is also 60 degrees, once this temperature is exceeded, it is difficult for human beings to survive, after all, under the high temperature of 60 degrees, plants and animals cannot survive, and human beings will lack food and face famine, at this time, even if human beings can withstand the high temperature, they will starve to death because of lack of food.

Although human beings seem small, they tend to have a strong ability to withstand high temperatures and are also very adaptable to the environment. If this temperature is exceeded, it is easy to cause damage to the body, and if it is too cold, the body will automatically consume energy to maintain the basic operation of the body. However, if the temperature is too low, then the temperature in the body will not be able to match the sister, if it is too hot, it will not work, and the body will not be able to adjust the temperature by itself, so it is easy to suffer from heat stroke, whether it is heat stroke or hypothermia, it is fatal for humans.

The reason why human beings can withstand high temperatures has a lot to do with the humidity of the air, after all, human beings regulate the temperature of the body through sweating, and when the air humidity is too high, it is difficult for the sweat from the human body to evaporate, and it will feel stuffy at this time. Although some animals also sweat, the sweat of these animals is lipid, not water, only human sweat is water, so it is easier to evaporate and regulate the temperature in the body.

This year's summer has been very hot for people in many provinces, and the hottest time has reached more than 40 degrees. When human beings work outside, they will feel very hot, and once the temperature in the body is too high, it is easy to damage the internal organs, which is the so-called heat stroke, which basically does not have any means, so when encountering high temperatures, it is necessary to self-regulate the temperature in the body.

For human beings, high temperature is not actually the most terrible, the most terrible is the lack of food, once the high temperature reaches a certain limit, crops will die directly, even if it can be insulated by high technology, so that it is impossible to plant crops in a large area, at this time the food output will be reduced a lot, and the number of human population will definitely decrease.

One is the case of dryness, studies have shown that humans can work normally in a dry environment at 54 conditions; The other is humid – that is, in a sultry situation, where studies have shown that when the air humidity reaches 100%, the human limit temperature is 35, and it can only last for a maximum of 6 hours.

If the temperature is as high as fifty or sixty degrees, it will be difficult for people to survive. Because of this, crops and other creatures will die, and human life will not be guaranteed.

In a dry environment, humans can work normally at 54. If it's 100% humidity, the limit for humans is 35.

The world will become very barren because all living things will not exist, and the earth will become very barren.

There will be fewer animals in the world, humans will freeze to death because the temperature is too low, and few will survive, and they will be replaced by other things.

That world will become a world of ice, and there will be no way for humans to survive, and many creatures will become extinct.

Introduction: If the temperature is as low as minus 100 degrees, the harm to the earth is very great, and it may plunge the world into a crazy situation, and it feels particularly cold. No matter where you are, you may be frozen into sculptures, and the hope of staying at home is also very slim, and the earth is likely to fall into a state of inactivity.

Do you know how many degrees can freeze people, the upper limit of normal armpit temperature should be 37 degrees 4, if the weather is very hot, the maximum temperature is only 42 degrees, at minus 100 degrees, people will definitely freeze to death, your blood clots, your heart freezes, you can't make blood, in very cold places our hands will definitely feel cold, ** will feel very stinging, over time it continues to increase, slowly because the temperature is very low cause people to have difficulty breathing, Blood circulation in the human body also slows down, the body feels stiff, and the mind becomes slow and chaotic. The whole earth may fall into the same state, and eventually the body temperature will gradually drop, and the body will gradually stop thinking and finally die.

After thinking about it for a while, if we really live in an environment of minus 100 degrees, it is estimated that it will not last long, after all, the maximum temperature that the human body can withstand cannot reach there. The reason why human beings can live on the earth is because they are homeothermic animals that can regulate their own temperature, and we don't need to spend a long winter next year, but the temperature is too low, and we can't adjust this temperature in other ways. Of course, you can live in an area of minus 100 degrees by chance, you must have some warmth measures, and then carry out myopia sports and baking fire to keep warm, minus 100 degrees it should not be considered a desperate situation, of course, this can only be extreme weather, can not survive for a long time.

This situation can have very serious harm to the earth, causing life on the earth to not be able to live properly. It will also lead to threats to the survival of human beings, and it will also lead to abnormal conditions on the planet. There are also instances of the ocean freezing. Extreme weather can also occur.

The earth will become a glacier, all living things on the earth will die, which will cause all microorganisms to disappear, and the earth will enter an ice age, and all living things will disappear, which is a harm to the earth.

It will cause the temperature of the world to drop completely, the earth will become a frozen world, human beings will stop moving, all animals and plants will perish, and human beings will not be able to survive for a long time.

It will affect the normal cycle of the earth, cause a large number of species to die, affect the ecological balance, affect the magnetic field, and affect the operation of the earth.

The animals on the earth will die, the plants on the earth will die, the humans on the earth will die, the creatures on the earth will die, and the vitality of the earth will decay.

The change of seasons is a very normal phenomenon in the midst of the four seasonsThe temperature varies from season to seasonEven in the coldest winter, some places will be more than ten degrees below zero, and you can live a good life. But if whenThe temperature was as low as -100 degrees Celsius, it can have a very big impact on people, and it may even comeIn the end, it was completely destroyed

For some room-temperature organisms, the temperature is minus 100 degreesFatal for them, because they already need to hibernate in the winter. If the temperature had been so low for a long time, they wouldn't have it at allThere are places to hibernate to raise your temperature, so in the end their species will all perish. And on Earth it is possible tooNo crops survive, Roll at this time, the whole earth isA frozen state, the ground soil is buried under the ice,You can't even provide water to the plants, not to mention let him grow.

Although humans haveLots of warm gear, but as the temperature keeps dropping, there will be no way out of the end of the dayGet the power to support the operation of your cold equipment。For people, the simplest and most convenient way is also the most straightforwardIt's about wearing a lot of clothes, jacket.

Or a down jacket, but in an environment of minus 100 degrees, it is difficult for us to even want to go out, on the roadDefinitely notTransportation。If you have seen the Wandering Earth.

friends, you know that in this movie, it's becauseGlobal temperatures are low, so peopleClasses simply cannot survive on the ground, then if the temperature is low toMore than minus 100 degreesIt is also possible that this is the case. In the long run, peopleThe class has to be prepared for this to the resource,MoreoverIf there is a shortage of food, there is no wayLive on the ground again.

People are neededEat lots of foods to provide daily nutritionVegetables and meat can be nutritionally balanced, but when the temperature is low, we don't have access to these resources, when the resources are scarcePeople may drive up prices and grab resources。At this time, the human race will decrease dramatically, because there is no resource support, soIt can only eat the weakAnd the whole earth is very cold, even if you want to catch food by yourself, it is very difficult, because90% of all living things on Earth die in a flash。It is possible that only a few animals that live in the cold zone will survive, and there will be a few bacteria that can surviveIt's hard for living things to survive in such an environment.

Many organisms will die, plants will not survive properly, there will not be enough food, it will cause the whole planet to change, and the oceans will freeze.

Plant species may be the first to wither, vegetables may not be grown, the water surface will freeze, tropical fish will not survive, and biological species may decline.

Plants will not grow old pants length, slowly celebrate or there will be no resources, in the early stage, people will be crazy to buy resources, and in the later stage, all humans should die, and the earth will become an ice hockey.

If the Earth's temperature reaches 70, will humanity perish? Scientist: Humanity is not going to perish.

What is certain is that the sudden rise in human temperature will cause more than half of all deaths. The melting of Antarctic glaciers at 70°C will lead to global climate variability and reduce the living space of sea level rise.

In recent years, with the gradual change of global climate and the continuous emission of greenhouse gases, the ozone layer in the two regions of the Arctic and Antarctic has been hollowed out. A large amount of ultraviolet light hits the earth. It can be said that there is no one on the planet at the moment.

The future development of human society is also unstable, especially in the current environment, the global climate is constantly warming, and people feel hotter and hotter every summer. If someone comes up with a hypothesis, if the temperature of the earth reaches 70 degrees, will humanity perish? This answer is certainly possible for the following reasons.

Of course it will perish. When the temperature reaches 40 degrees in summer, everyone can no longer stand it, not to mention 70, 70 water temperature bathing is not good, some proteins begin to coagulate, plants and animals will die due to overheating, and the human body will directly can't stand it and die.

The temperature on Earth plummeted to minus 200 degrees overnight, and the phenomenon that would occur was that all matter, including humans, would be frozen up.

Under ultra-low temperature conditions, the properties of many metals have undergone "rebirth" changes, and the steel with good toughness has become brittle like ceramic, and it will be crushed if it is knocked out; As for the tin, it has become a pile of powder without touching it;

Mercury that could have flowed was as hard as iron; Of course, there are exceptions like copper, aluminum, and nickel that retain good toughness and mechanical strength at very low temperatures.

At ultra-low temperatures, in addition to metals, other substances will also undergo unrecognizable changes, soft and delicate flowers will become like glass after being immersed in liquid air, and will tinkle and jingle; At very close to absolute zero, oxygen is like white grains of sand, hydrogen is as hard as stone, and almost all gases become solid.

The only exception is ammonia, which is still a liquid, but when ammonia is cold, it will become a liquid that can "climb" and "climb";

If a small cup is placed in a large cup, and the small cup contains liquid ammonia, when the temperature is cold, the liquid ammonia in the small cup will automatically "crawl" out along the wall of the cup and flow into the large cup until the liquid level of the large and small cups is flat.
