What Causes the World Population Problem 35

I think there are several reasons for the rapid population growth:

1.With the rapid development of the economy, people's living standards have improved! Resulting in a high birth rate and a low mortality rate!

2.After the two world wars, the further recognition of the huge role of human beings in the economy and military provided theoretical support for the rapid growth of the population, like the population theory of ***!

3.The relatively peaceful political and economic environment of the world is an important environmental factor for the rapid growth of the population!

That's all for now!

1. Improving living conditions, good nutrition, and more fertility.

2. Improvement of sanitary conditions.

3. The old concept of having more children and more blessings Management is not thorough enough.

4. The world environment has changed peacefully, and large-scale wars have not occurred.

5.The elderly population is increasing, which means that people are generally living longer.

Improved living conditions, good nutrition, and more childbearing.

Sanitation improved.

The elderly population is increasing, and the old concept of having more children and more blessings is not managed thoroughly.

The world environment has changed peacefully, and large-scale wars have not occurred.

The high socio-economic development has led to:

Developing countries have high fertility and high survival rates.

Developed countries have low fertility and high survival.

And then you know. The root cause of the growing global population in developing countries.

People's thoughts! People tend to think that people are so good! Is there power when there are more people? But people are not ants! Now this idea still exists, no matter how poor the family is, it has to be born, and thus leads to the growth of the population!

It is only now that family planning is taking place, the economy is developing rapidly, and people's living standards are improving! Resulting in a high birth rate and a low mortality rate!

1. Improvement of living conditions.

2. Improvement of sanitary conditions.

3. The old concept of having many children and being blessed.

4. The world environment has changed peacefully, and large-scale wars have not occurred.

The contradiction between population growth and limited environmental resources.

There is only family planning in China.

People want to have more children to support their families!

At present, the world population is facing two major problems: first, the population is growing too fast; Second, social development is unbalanced.

The rapid growth of the population has imposed a heavy economic and social burden on developing countries. Because of the different levels of development between poor and rich countries, the gap between them in terms of living standards and the quality of their populations, including health and education, is widening, which is extremely detrimental to the balanced development of the global economy and society.

1. The demand for productivity for the overall economic growth of the world, especially the people as managers.

2. At present, the world is peaceful and stable, the economy is prosperous and developing, and people live comfortably, which is conducive to organizational life and family. (War is not like this).

3. The living conditions have been improved, the modern medical facilities have been improved, and the birth mortality rate has been greatly reduced.

4. Changes in people's concept of life and natural needs for physiology.

5. The inevitability of human reproduction.

Success!

1. The development of the mouth is uneven.

2. The development of the level of productivity cannot keep up with the needs of population growth.

3. The concept and policy of fertility among various ethnic groups are not scientific, resulting in the unbalanced development of the racial population.

4. Lack of planning and management of population migration.

5. There is an imbalance in the contribution and feedback of human resources.

6. With the acceleration of globalization, the global village lacks long-term unified development goals.

7. The aging of Europe, Asia and the United States restricts the development of the raging society.

8. The regional competition of economic growth restricts the rational distribution of population, including spatial population density and industrial population density.

The level of development in various regions is unclear and frank and rotten, which leads to population migration.

In population statistics, the phenomenon of a population whose place of household registration is inconsistent with the place of current residence and who have been away from the place of household registration for more than half a year is collectively referred to as "separation of households".

"Separation of households" can be divided into inter-provincial household separation and inter-district (county), street, and township (town) household separation within a province (city) according to whether the separated space crosses provincial-level jurisdictions. Among them, the former is called inter-provincial floating population, which is a long-distance flow across provincial boundaries, and the latter is called intra-provincial (municipal) flow.

The movement of people between the workplace and the place of residence, which generally does not exceed one day and night, is also known as daily movement. For example, farmers go to the fields during the day to plow, and the respiration leaks to the villages at night; Fishermen go to the sea to fish for a day or a few days, and then return to the fishing port, etc.; But more importantly, it means that people living in the suburbs go to work at their places of work in the city every day.

For example, in a 1970 survey, the population of the central area of Tokyo was 10,000 at night and 10,000 during the day, indicating that there were 10,000 people who traveled between the city center and the suburbs every day. This phenomenon is also seen in some metropolises such as New York, Chicago, London, Paris, Mexico City, etc.

Reading the migration path map of refugee flows, the root cause of the hunger in the mountains in 2015 is ( )aDecline in income bFrequent cThreat of war dDifficulty in finding employment.

I don't know about other cities, I'm from Beijing, so I'll tell you about the situation and data in Beijing.

In general, there are many employment opportunities in Beijing, but the corresponding competition is very fierce, and the relationship between people is very cruel, people have no sense of belonging and no life, some people will be lost, so that the city tends to be stable and healthy.

Beijing's permanent population peaked at 21.72 million in 2016, but has since declined to 21.53 million in 2019. In addition, the number of births among Beijing's permanent residents has also been declining for several consecutive years.

This population decline may indicate problems in Beijing's development environment, living conditions, and urban governance, such as high housing prices, which have caused some people to choose to leave the city; Environmental pollution and traffic congestion may also be one of the reasons why people choose to leave Beijing.

It is difficult to develop in the future, but according to the census data, the actual permanent population of Beijing has actually increased by 360,000 compared with the previous statistics, reaching 21.89 million. At the same time, if Beijing sells tomatoes and adds a floating population, the number of people traveling may be even higher. Therefore, the population problem in Beijing needs to comprehensively consider various factors and formulate more scientific and reasonable guidance and control policies to promote the healthy and sustainable development of the city.
