Why is the population growing so fast?

1, the development of science promotes the progress of medical care. With the development of medical and health undertakings and the improvement of modern medical facilities, the number of newborn babies is far greater than the number of deaths every year, which makes the total population grow continuously.

2. With the development of economy and the improvement of living conditions, people pay more attention to nutrition and health in their diet, which leads to the decrease of mortality.

After the industrial revolution, the productivity of human beings has developed by leaps and bounds, enabling human beings to obtain more natural resources and manufacture products, thus promoting the development of science and agriculture and producing more food to feed more people.

4. Furthermore, due to the government's encouraging policies, for example, after the founding of the People's Republic of China, China advocated having more children to prevent foreign invasion, and the population of our country soared from 400 million to 654.38+300 million.

5. After World War II, the world situation was relatively stable, and the mortality rate dropped. At present, the world is peaceful and stable, the economy is prosperous and developing, and people's lives are comfortable, which is conducive to organizing their lives and families, making the world population reach an unprecedented number.

Extended data:

I. Enlightenment of world population change on development:

1. Improve the coordination mechanism of population development and promote long-term balanced population development. In the next 30 to 40 years, China will be in a deep transition period of population development. During the "Thirteenth Five-Year Plan" period, we should focus on the implementation of the universal two-child policy, actively build an institutional environment and service system to encourage policy birth, and promote the gradual recovery of fertility rate.

2. Strengthen the mechanism of population planning, monitoring and forecasting. Improve the monitoring and evaluation system of population dynamics and scientifically monitor and evaluate population changes and trends. Establish a normalized population forecasting mechanism and regularly publish national population forecasting reports.

3. Strengthen risk prevention and actively respond to various population problems. Strengthen advance planning and strategic prediction, attach importance to grasping the relationship between population elements, as well as external factors such as population, economy, society, resources and environment, prevent and comprehensively respond to potential security problems within the population system and security challenges between systems in advance, and effectively guarantee population security.

Second, the distribution characteristics of the world population

1. The distribution of population growth in time and space is unbalanced: the time for doubling population growth in this century is shortening; The growth rate varies greatly between continents and countries.

2. The world's population is mainly concentrated in the northern hemisphere and the eastern hemisphere, and concentrated in the middle and low latitudes and coastal areas.

3. World population structure: The population is aging rapidly. (white hair and waves)

4. World population migration: large-scale population migration in modern times: Europe immigrated to America, Australia and New Zealand, Africa immigrated to America, and Asian countries immigrated.

5. Population problem: the population growth is too fast, and the population is over-urbanized in the process of urbanization.
