What do you think will happen if the world s population is reduced by 90 ?

The pressure on non-renewable resources is reduced, and even converted into renewable resources; The efficiency of the use of renewable resources has declined – for example, hydropower stations do not need as much electricity, and many hydropower stations will certainly only retain their role as flood control and storage, and will no longer operate to generate electricity.

The world economy is also likely to be sluggish due to the collapse of demand (there seems to be little need for infrastructure investment without people, and the real estate industry seems to be doomed), and the disappearance of debt payers and debtors could trigger a global economic crisis.

On the economic side, although there is a much smaller industrial population, the automation of the modern industrial system will make it possible to restore productivity in fewer people than imagined, and more quickly.

The resources of the economic system, such as money, are too many; the collapse of the human resource network; The system of information resources collapsed.

The Arabs of the Middle East could become the dominant population of Europe with a high enough fertility rate, which in turn would turn Europe into another Middle Eastern region and grow into a significant power.

In terms of social resources, a lot of the infrastructure that has been built is wasted – like schools, where there are simply not so many children going to school, not so many sick people.

Under the threat of national survival, the principles of various countries may become more radical, and the old developed countries such as Europe and the United States may take advantage of the military superiority they still have to clean up other "invaded" high-fertility populations.

When you go to work in the morning, the subway station will no longer be crowded, and you can also get up a little later to go to work.

It seems to me that countries in the Asian region, such as China, India, Indonesia, etc., may become the last building blocks of civilization.

When a country's population decreases, the pressure of job competition decreases, people's wages will rise, housing prices will decrease, the population will age seriously, and the pressure on young people will be huge, which may directly affect the economy of a country, and there may also be a situation where the environment improves, garbage emissions decrease, and so on.

South Korea's population situation has not been very optimistic, the birth rate has been declining for many years, and the birth rate has maintained the world's lowest good results for three consecutive years.

Koreans are very magical, their country is relatively average, but the development is very good, but there is also a relatively serious capital monopolized by large enterprises, the voice and status of industry giants are very high, and many people in order to get promoted and raise salary, they can't join if they can't fight, which makes many young people who want to work their own feel desperate, many movies and TV series made in South Korea can be reflected, although the movie point vision can not be fully reflected, But it can also reflect a lot of things, because South Korea has always been known for daring to shoot and shoot truthfully.

South Korea's wages are very high now, and the wages of part-time jobs are very high, and many foreigners will choose to work in South Korea to make money, and then return to their own countries to retireWhen people have money, they begin to roll in, everyone wants their sons not to lose at the starting line, so they attach great importance to learning, start to ask teachers, start all kinds of tutoring, whether it is parents or children themselves, the pressure is very great, if you can't go to a good school, you may not be able to find a good job, and then there is a vicious circle, if your academic performance is not particularly good, you have to work very hard, so raising children is ranked behind, not to mention spending energy and money, so everyone's enthusiasm for having children is reduced.

Then there's the issue of house prices, South Korea's housing prices are also very high, ordinary people may work for 10 years to buy a house of their own, although it is slightly better than our country, after all, the salary is high, but the pressure is not small, South Korea's various reasons have caused a low birth rate, which has a smaller and smaller population in South Korea, if it has been maintained like this, then it may be that Koreans will disappear from the earth.

When the population of any country is declining, it is necessary to pay attention, because the population is small, then the wages to workers will rise, the cost of investment is high, it will not attract more investment, if it continues to decrease, then housing prices will also be greatly affected, life may be affected, the development of a country is inseparable from people, then the population reduction will definitely affect the development of the country, such as Germany, Japan and other countries because of the population decline directly affects the national economy, and with the increase of the elderly, There will also be pension issues, and young people will increase the pressure, so there are so many things that can happen when a country is depopulated, both good and bad, but I think the disadvantages are even more.

This is the Earth after half of the population has suddenly disappeared, where your wages have risen several times more than before, and you are the only person in your area who can fix cars, perform surgeries, or cook well. All of your peers and competitors have almost disappeared. Your skills are now in demand more than ever, and this has led to more money being earned.

In addition, high rents and mortgages like mountains have become a thing of the past forever. Because of the severe decline in the population, many houses are vacant. Now whether you want to live in **, the rent and housing prices are very cheap.

And not only that, but in addition to the many unexpected benefits that we humans will have, the planet itself will begin to change.

The first is the climate and the environment, fewer people means less pollution and emissions, and the earth will gradually start to repair itself during this time, and according to scientists.

It is speculated that if the population of the earth were reduced by 50%, the remaining humans would most likely live comfortably for the next 100 years. Of course, all of this is only possible if you are lucky enough to survive this cosmopolitan event. Population extinction crisis, considering that the total population of the world is about 7.7 billion people, and you only have a 50% chance of being one of the remaining 3.8 billion people.

Half of the population may be leaders, police, firefighters and power grid workers, and their disappearance will immediately have a serious impact on the world, and because of the professionalism of the industry, there will be no one to replace them in a short period of time, and large-scale power outages are inevitable. In addition, due to the decrease in the number of people who grow, produce and transport food, our food ** chain will also be seriously affected, and material scarcity will become a norm. But don't worry too much, because humans have had similar experiences before.

In the mid-14th century, there was a battle known as the Black Death.

The terrible virus swept across the continent, directly causing the deaths of almost 25 million people, which was about half of the continent's total population at the time. Although the virus brought endless despair to the people at the time, the event also brought some surprises, and the reason for the increase in people's living standards during that period of food scarcity was due to the fact that fewer people consumed food.

According to statistics, about 36 million people die of hunger every year, so once half of the population disappears, at least there is no need to worry about people dying from hunger. Of course, all of this is just a scientific hypothesis and a projection, even if half of the population suddenly disappears now, and in a few centuries or so, humanity may return to where it started, but one thing is for sure, the planet will indeed become healthier after half of humanity disappears. In addition, the core of the problem is not how many people we have, but how we should use and protect the earth's resources.

The rapid decline in the population will lead to a significant reduction in the demand for human resources in all fields, and the number of mental and manual workers will also decrease, and economic development will be affected to some extent.

It will lead to a significant failure to keep up with productivity, and at the same time, it will also have a great impact on the world's population resources, and will lead to the development speed of many industries not keeping up.

First, we will be in the pain of losing loved ones, and secondly, the world will be in chaos, planes will crash without piloting, and flora and fauna will increase and occupy people's living areas.

The labor force of the world with a declining population is particularly high, and the talent war in various countries may be more serious, and the social economy may stagnate.

A country's economic development depends on the people of a country, and only when the country has people will the country innovate and develop. It is difficult for a country without people to develop, first of all, the labor force is insufficient, and people's enthusiasm for labor may not be high enough, and secondly, the development of the country may also be hindered, and the decline in population will also affect the daily life of everyone in the country. <>

First, the ability to innovate is insufficient

As the saying goes, more people are stronger, and the same is true for the development of a country, the country has a large population, and people will have pressure and competitiveness, which also promotes the birth of some new products.

China's rapid development and the emergence of a variety of innovative products are due to China's large population, and the number of patents in China every year is particularly large.

But if there is no one in the country, because of the shortage of labor, the pressure on people will be very small, people will have no motivation to innovate, and the cost of employment will also rise for the country and enterprises due to population decline. <>

Second, there is a serious shortage of labor

China is a developing country, the country can be in just a few years, the country's economy has been qualitatively improved, mainly because China's labor force is more and cheaper, so many Western countries like to build factories in China.

Moreover, the main reason for the current stagnation of development in some Western countries is also because of the declining population, insufficient labor force, and high employment costs, so Western countries encourage childbearing. <>

If the population of a country is declining, it will cause a shortage of labor, and the shortage of labor may have some daily necessities, some things can not be produced, and in shopping malls and some public places, there may only be robots to guide people, which will also make people's lives change dramatically, and may cause inconvenience to people's normal life.

If there is a real population decline in the future, then the prices of the whole world will be lowered, because the material resources are extremely abundant, ** will not be very high, but this will also seriously affect the life of each of us, and industrial development will become very slow.

It's going to be very devastating, and it's going to cause a lot of problems in the world, and it's going to cause some economic crises as well. At the same time, it will also affect everyone's life and reduce everyone's standard of living.

If the population declines, the world's population will be very small, and the slow development of the world will become very slow, and eventually the world will lead to extinction, so the population decline will affect everyone's life.

The world in decline will be very decadent, the whole world will become very desolate, and the depopulation will affect the economy and production, and it will affect everyone's life.

It will become bad. Yes. Because a declining population will make us less communicative. And the world will be less able to work.

The development of this world will be slower and slower, and society will not be able to meet people's needs, and it will be, first of all, it will lead to people needing fewer and fewer things.

Labor shortage: A declining population may lead to a labor shortage, which will adversely affect economic development and social stability.

Population Ageing: With a declining population and longer life expectancy, the problem of population aging will become increasingly prominent. This will put enormous pressure on social welfare, health care and pensions.

Economic recession: A declining population can lead to a decrease in market demand, which in turn affects economic growth.

Shrinking markets: A declining population can lead to a shrinking market, affecting production and sales, which in turn affects economic growth.

Shifts in social structure: Population decline may lead to changes in social structures, such as changes in family structure, occupational structure, lifestyle, etc.

Ecological changes: Population decline may reduce human impact on the natural environment, but it may also lead to ecological imbalances and biodiversity reduction.

In short, the decline of human population may cause a series of economic, social and environmental impacts and challenges, which must be dealt with by effective measures.

Negative population growth has the most serious problem for the average person: who will take care of the elderly.

Negative population growth will exacerbate the declining birthrate and eliminate the growth potential of the working-age labor force. At the same time, the elderly population will increase sharply, the young and middle-aged population will decrease sharply, the pensions received by in-service workers will decline, the total amount of pensions will increase slightly, and consumption will be large. That is, if the number of pensioners decreases sharply, and the number of elderly people receiving pensions increases sharply, the pension gap will become more prominent.

The most serious thing is that the service industry, including the pension, needs a large number of labor, and the population growth is negative, and the labor gap is even greater.

If you are bold, it will be difficult to find street sweepers in the future. Bottom line: Who will take care of the elderly?

On the one hand, in order to increase the enthusiasm of young people in childbearing, it is necessary to take practical measures, including comprehensively alleviating the cost pressures of marriage and childbearing, children's enrollment in kindergartens, and urban housing. Only in this way will young people dare to get married, dare to have children, and want to have children! At the same time, vigorously develop new technology industries, promote the development of humanoid robots, especially domestic robots, and alleviate the problem of labor shortage in the service industry.

We will continue to make efforts in childbirth support and family building, promote the simultaneous development of fertility policies and relevant economic and social policies, and do a good job in housing, education, medical care, employment, taxation, and social security suitable for families with children. Actively build a reasonable cost-sharing mechanism for childbirth and a policy support system conducive to childbirth, effectively reduce the burden of family childbirth and childcare, and stimulate fertility potential.

With the focus on "one old man and one tong stool to start the young", establish and improve the population service system covering the whole life cycle, and strengthen the function of grassroots children's elderly care services.

It is an obvious phenomenon that the change in the concept of fertility has led to a decline in the absolute number of births. In fact, the population of many developed countries and cities is already declining, and the concept of fertility in rural China is also changing. The global population decline should come sooner and faster.

Pay attention to family style, build a culture of marriage and childbearing, carry forward the traditional virtues of the Chinese nation, respect the social value of childbirth, encourage couples to share the responsibility of childcare, and tell the Chinese story of love in the new era, a harmonious family, and a happy life. A very effective way to imperceptibly.
