What will happen if the population decreases?

This question is very interesting. It's fascinating. Therefore, I judge that the following changes may occur in the population reduction.

1. What will happen if the global population decreases 1%? At present, the global population exceeds 7 billion. If the global population decreases by 1% (about 70 million), it will have little impact on all countries in the world. Should eat or eat, should drink or drink, should go to work or continue to work. I don't care too much about the sudden loss of 100 people.

2. What will happen if the global population decreases by 10%? The decline of 10% may begin to attract the attention of many countries. For example, sparsely populated Russia, Japan and South Korea, where the fertility rate has been declining, and so on. The sudden loss of such a huge population will begin to threaten the national economy, especially some job vacancies, but fortunately, talents can be introduced from low-income countries to make up for the vacancies.

But for some densely populated places, such as India, it is a good thing. Population decrease 10% means a decrease of 65438+35 million people. Great relief has released too much pressure, including survival pressure, housing pressure and employment pressure.

Therefore, there will be a population distribution pattern in the world. But after all, for the world, the population is as high as 6.3 billion.

What will happen if the global population decreases by 25%? If the global population of 1/4 suddenly disappears. At this time, the world may be better and richer. For example, with so few people in the existing environment, we can basically achieve collective material prosperity, and the released food can completely fill everyone in the world, and the released jobs will also give everyone in the world something to do.

Many farmers in mountainous areas don't have to worry about not farming, and they are not afraid of not having a job when they enter the city. As a result, the population moved from mountainous areas to plain areas. Plain areas migrate to cities. In the end, more mountains will return to the original ecology at one time.

The world will also undergo new changes, that is, to truly realize "people-oriented". After the compression of human beings, compared with today, only 75% of the population will obviously live a better life and have a higher quality. Workers will basically stop worrying about unemployment, because the cost of temporary workers is much higher than that of regular workers.

However, a population decline of 25% will be a disaster for sparsely populated areas, and they have to completely liberalize their immigration policies to attract new population.

What will happen if the global population decreases by 50%? At this time, there are only 3.5 billion people left in the world, 100 villages, and there are still 50 people left. Then compared with today, more than 80% of the world will no longer be inhabited by human beings. For example, villages, towns, townships and even county towns. Because there are so few people, the whole industrial chain of survival is almost broken. They had to move completely. In addition to disappearing settlements, more than 70% of enterprises and individuals may disappear because there are too few people to make a living.

Behind the inability to make a living is a lack of vitality. The pace of human life will also slow down. Because life will be here, you don't need to work so hard.

I am afraid that by this time, many policies will disappear, such as land, hukou, visas between countries and so on. Some countries even try to attract foreigners to work and live by sending real estate.

On this day, energy will not be important, and money will not be important. Our planet will be more beautiful when it becomes slim.

5. What will happen if the global population decreases by 80%? The population of China accounts for about 1/5 of the world's total population. When there are only1400 million people left in the world, the total population of the whole world is equivalent to that of China now.

As for China, there will only be about 280 million people, less than the population of the United States today, and there are only over 60 million people left in the United States. As for Russia, there are even fewer, with only more than 20 million people left. At this time, the real advantage dividend of the population will come out. America will decline because of insufficient population.

As for Russia, the population is basically concentrated in a few cities, and the rest will become no man's land.

There will be no military conflict or war in the world. Because war is meaningless. What followed was the retrogression of the development of scientific and technological civilization. This is the worst result of disappointing.

Many foreign trade in the world will also be suspended, and many manufacturing industries will stop production. Because there is no demand in the world. By that time, the environment of human life seems to be like a stand-alone game. Will lack motivation and pursuit.

6. What will happen if the global population decreases by 99%? When there are 70 million people left in the world, it is equivalent to distributing the population of Hebei Province to the whole world today.

There are only 7 1 10,000 people left in Hebei province. In this world, I am afraid that mankind will lose communication and many electronic products at once, because too many things are meaningless. Man is truly integrated with nature for once.

Many countries will be forced to declare merger because of insufficient population. Because they are so lonely. They have been unable to form a perfect social order on their own and have to rely on other countries.

Summary: A large population is not a good thing, and a small population is actually not a good thing. In my opinion, it is best to catch a point. This point is the load that the power of the earth can bear. Overpopulation will cause resource shortage and environmental degradation. If there are too many people, civilization will stagnate and lack innovation. So the right one is always the best.

As a social group, it is a leader to complete and realize the materials needed for social development to maintain life, reproduce and maintain health. Let this human society develop and evolve is the law of human development! When human development reaches its peak, it should be artificially restricted, so that the whole human society can develop normally and orderly and make society progress!

However, with the decrease of population, there may be side effects, and the means of production of human society may be disconnected. This involves people's pensions, so it must be adjusted artificially, which is also called artificial nature, not regular nature! Develop population and make human society prosperous in an orderly way!

If the population decreases too fast, it will soon enter the elderly society and make the society lose its vitality. The population is growing too fast, and the problem is more serious, like those countries in Africa. The key is to plan ahead and establish an effective pension system, so that our elderly friends can have a sense of security, security and happiness.

1, the population is aging seriously and the number of young people is decreasing.

2. Young people gather in first-tier cities, while the population of other cities is gradually decreasing.

3. House prices in most cities will gradually go down, because no one will take over, and house prices in first-tier cities will be firm.

4. More job opportunities, more income and less pressure on life.

With the decrease of young labor force, it becomes more difficult to get married and have children, and the policy of encouraging childbearing will be introduced to promote consumption and make the population structure more reasonable.

6. Machines will largely replace manpower, and manual labor and simple operation skills will be eliminated.

7. With the development of science and technology, safer and cheaper digital currency will completely replace paper money.

8. The gap between the rich and the poor is widening.

Opportunities:

1, the pension industry and service industry are unprecedentedly developed.

2. Games and travel.

3. Internet, digitalization and artificial intelligence.

Look at Japan today. The key point is that we haven't accumulated the social wealth before Japan's aging.

When the population decreases, many industries will be cut as the population decreases; For example, maternal and child health centers, such as supermarkets and factories, will be gradually reduced with the decrease of population. The forest area will increase, there will be more wild animals, the offshore fishery will be fully rested, the water quality of rivers and lakes will be better, the air quality will be improved, and the congestion in big cities will be greatly alleviated; The employment rate will be coordinated with the demand of the population market, which is an inevitable phenomenon of population decline.

Now I understand that the reason for the small population abroad is that when a country has too many people, it must be developing. The demographic dividend has created everything in the plan. When it is gradually reduced, so many people are not needed. At this time, it will be saturated at some point. In another hundred years, the population will be between several hundred million, and the economy will depend on population balance. At this time, there is no need to build super-large and super-dense buildings. High-tech leads coquettish, and everyone is more.

The decrease of population will directly lead to the slowdown of economic growth and restrict economic development. At the peak of population in 1980s, China attracted a large number of foreign investors to invest in China because of its surplus labor force and low labor cost, which promoted the rapid economic development. With the increase of labor cost, it is difficult to recruit workers along the coast, which leads some enterprises with low added value to move overseas or inland from the coast.

Of course, the relocation of these enterprises is not only due to population decline and rising wages, but also to changes in the international market and rising prices of raw materials, resulting in reduced profits. But there is an undeniable fact that human resources determine the development of productive forces.

The current countermeasure is to replace human resources with intelligent machines. When intelligent machines cannot completely replace human resources, the economy will be affected and will slow down.

Japan, South Korea, Germany and the United States are all experienced countries, and the economic slowdown is directly due to the reduction of the demographic dividend.

Population decline will lead to the aging of society and the problem of providing for the aged is serious. China's aging has begun to appear, and the average life expectancy in China is 75 years. In 200 1 year, the average life expectancy in China was 7 1.8 years, and198/kloc-0 was 67.77 years, which increased by 4 years in 20 years. Before the founding of New China, the average life expectancy in China was only 35 years.

When people enter the old age society, it will inevitably increase the burden of providing for the aged and occupy social resources; On the other hand, the birth rate is low or even negative, which leads to the imbalance between death and birth rate and increases the burden on families and society. It is rare for a couple to raise three or four old people. At the same time, the old-age care system is not perfect, which is unbearable for young people who are sick, and it is extremely harmful to society, which leads them not to have children, forming such a vicious circle.

A large number of workers are lacking, social jobs are vacant, on the other hand, families are overburdened, and a large number of laborers over 70 years old will return to the job market.

When the population decreases, cities will shrink, some of which are due to the exhaustion of resources, and some are due to other reasons. Population decline will inevitably lose the consumer market, resulting in damage to related and manufacturing services. Urban shrinkage is caused by the decrease of population migration, leaving a large number of houses vacant. The main reasons are the migration of population and the exhaustion of urban resources. For example, the state controls polluting coal mines, leading to transformation. Until then, those industrial workers will move away.

This is just a microcosm. Population migration makes it difficult for the economy to drive development. And directly affect consumption, leading to the intervention of manufacturing, service and other related industries, hindering economic development.

Population decline will increase employment opportunities, the living environment will definitely change, and house prices will plummet. The decrease of population will definitely increase employment opportunities, and there will be a shortage of manpower in traditional construction, service and manufacturing industries, which will directly lead to an increase in wages.

Due to the decrease of population, automobile exhaust and indoor air conditioning emissions will be reduced, and the living environment will be better. Pay attention to health, because there are few cars and no traffic jams, people are more willing to leave big cities and live in the suburbs.

As we enter an aging society, the pension industry will have a bright future. At the same time, few people are used to living in the countryside, which will inevitably lead to serious vacant houses, and cabbage prices will become a reality without deification.

In the long run, the population decline will definitely be unfavorable to the nation, which is manifested in all aspects of economic, national defense and social development. Otherwise, some western countries, such as Russia and Japan, have introduced policies to encourage childbearing because they have tasted the pain.

When the population decreases, the world will change greatly. Many changes have taken place in politics, economy and culture of human society. The subject said "decrease", not "extinction". There is a difference between the two, so we should distinguish them.

World population growth rate

The real estate industry will be hit. As we all know, China's housing prices are so high because supply exceeds demand. To put it simply, China has a large population, but the land is limited, and the number of houses is not enough for so many people to live in a short time. Especially in big cities, such as North, Guangzhou and Shenzhen. This led to high housing prices, so real estate used to be a pillar industry in China. If the population decreases on a large scale, the real estate industry will be hit hard and house prices will plummet. It has really become the "cabbage price" that Ma Dad said. At that time, each of us could live in a villa. I don't know if you are looking forward to it.

Agriculture is facing new challenges. In a short period of time when the population is decreasing, the prices of agricultural products will rise sharply. Because labor shortage will lead to a decline in crop output, which in turn will lead to an increase in agricultural prices. But after a long time, with the development of science and technology and the integration of the market, the prices of agricultural products will fall. Because Marx once said: technology can replace productivity. Deng Gong, the chief engineer of reform and opening up, once said: Science and technology are productive forces. In other words, when the labor force is insufficient, people will use technology to replace these laborers. For example, when the agricultural labor force is insufficient, people will use machines to sow, irrigate and spray pesticides. Of course, people still need to control or monitor these machines. After all, machines are still not as smart as humans. But this can also reduce a lot of labor, and the problem of labor shortage will not exist. Even agriculture will usher in great development!

High-tech agriculture

There will be great opportunities in the technology industry. As the population decreases, the welfare of the population will gradually decrease. The operating costs of all walks of life will increase. For example, the decrease of population density will lead to the further distance between cities, so the transportation cost will be higher. The decrease of population will also lead to the decrease of trains and flights, making it more inconvenient for people to travel. Business will also be more difficult to do, because the decrease in population will lead to a decrease in demand. But because of this, technology is bound to get greater development. This is actually not contradictory. The decrease of population will promote the development of science and technology. Because if human beings want to continue to develop, they must vigorously develop science and technology to make up for a series of social problems. In fact, this is not forcing yourself, and no one knows how much potential they have. At that time, agriculture, an industry that needs large-scale labor, will definitely be replaced by machines. Seeders are used for sowing, and drones can be used for irrigation and spraying agriculture. Although it can be used in some rural areas now, it has not been widely promoted. Will be widely promoted. In the future, there must be robots on the assembly line. They can work day and night without getting tired, not to mention getting paid every month. Then the price of industrial products will also drop sharply. Are you excited to think that our mobile phones and computers will be very cheap in the future?

artificial intelligence

It will recover naturally. Since the emergence of human beings, nature has been seriously damaged by human beings. Especially after the industrial revolution, environmental pollution is very serious. Many precious species have become extinct, and many large populations in the past are now on the verge of extinction and become endangered species. If the population decreases on a large scale, the earth's environment will definitely recover quickly. The number of many endangered species will gradually recover. Streets will be reoccupied by plants, and many uninhabited cities will become ruins and become a paradise for wild animals. Maybe each of us can keep a panda at home, just like keeping a kitten now.

Thank you for watching.

What will happen if the population decreases?

Generally speaking, population reduction is beneficial and land resources have been alleviated. If we go back to the 700 million population in the 1970s, it will be reduced by half. In China, mountains, slopes and small plots will not be planted, and returning farmland to grassland will develop well. A large number of farmers will be liberated to engage in other industries, while large areas of farmland will be leveled and mechanized for the use of ethnic minorities, and the remaining rural population can engage in industries such as old-age care. The development of animal ecology will be better protected, the animal reserve will be bigger, the damage to nature will be reduced with a few populations, and social development will not be greatly affected by a few populations.
