Natural Population Growth Rate The natural population growth rate is an important indicator that reflects the rate of population development and the formulation of population plans, and is also an important indicator in family planning statistics, which indicates the degree and trend of natural population growth.
It refers to the ratio of the natural increase in population (the number of births minus the number of deaths) to the average number of people (or the number of people in the middle of the period) in a certain period (usually one year), and is generally expressed in thousands. Natural growth rate of the population Birth rate - mortality rate of the population.
In addition, the natural rate of population growth can be expressed as the difference between the birth rate and the death rate of the population. The natural population growth rate is positive when the number of births exceeds the number of deaths throughout the year, and negative when the number of deaths exceeds the number of births throughout the year. Therefore, the level of natural population growth depends on the relative level between the birth rate and the death rate, and it is a comprehensive indicator of the reproduction activities of the population.
Attention should be paid to controlling the population growth rate as much as possible.
The natural population growth rate is the highest in Africa, with the average country reaching more than 2 per cent.

Summary. Dear dear, it's a pleasure to answer your <>
The constraints on social development caused by the degradation and depletion of resources caused by the rapid growth of the world's population are:1Energy Crisis:
The rapid growth of global energy consumption has led to a continuous increase in energy sources, exacerbating the tight supply and demand of energy and the lack of energy reserves. 2.Environmental Issues:
Due to overexploitation and pollution, various resources such as water resources, land resources, and forest resources are constantly decreasing, and the ecological environment is also damaged, and problems such as climate warming, acid rain, and marine pollution are becoming increasingly serious, which brings certain threats to human survival. 3.Economic issues:
The scarcity of resources and monopoly lead to the inevitable impact of commodity and economic development and results, and more broadly cause social injustice and the widening gap between the rich and the poor. <>

With the rapid growth of global population and social and economic development, the consumption of resources has accelerated, and the quality of the environment has been seriously damaged, which has brought many constraints to social development. These constraints include the energy crisis, environmental problems, economic problems and social problems. In order to ensure the sustainable development of human society, it is necessary to rationally use resources and reduce environmental pressure through means such as saving resources, protecting the environment, innovating science and technology and systems, so as to achieve sustainable development of society.

Answer D: This question mainly tests the relevant knowledge of China's resources. With the growth of the population and the development of the social economy, the total amount is getting smaller and smaller, and the natural resources that may even be depleted are mineral resources. Land resources, climate resources, and biological resources are renewable resources, and as long as they are rationally utilized, they are generally recyclable.
-
China's natural resources are characterized by abundant aggregates and insufficient per capita resources, and with the growth of population, the per capita share of natural resources in China is bound to continue to decrease
So the answer is: key bend.

Answer B The basic national chaos and hunger of China's natural resources are: there are many types, the total amount is abundant, the dust is but the per capita share is small, and the population of our country is still growing, many resources are not properly utilized, and the destruction and waste of natural resources are serious, which will inevitably exacerbate the severe situation of natural resources.

Although China's birth rate remains at a low level, due to the large base, the total population will continue to increase in the coming decades, and the pressure on labor and employment is increasing. The task of improving the quality of the population is very arduous, and the problem of population aging is becoming increasingly prominent.
The contradiction of population pressure and resource shortage has become increasingly prominent, and there is a serious shortage of mineral resources, especially oil, which have a bearing on the national economy and the people's livelihood. In some localities, the phenomena of indiscriminate appropriation, indiscriminate occupation of cultivated land, and indiscriminate mining of mineral resources still exist.
The overall trend of deterioration of the ecological environment has not been fundamentally reversed, and the task of environmental governance is still quite arduous. The flood control system of major rivers is not perfect, and the water conservancy infrastructure in rural areas is relatively weak. The contradiction between the supply and demand of water resources is very acute, and it has become a prominent constraint affecting economic and social development and people's livelihood.
Hu did not sell Jintao said: We must soberly realize that the national conditions of a large Chinese population and a small per capita possession of resources will not change; the trend of decreasing reserves and available non-renewable resources will not change; the role of resources and environment in restricting economic growth is becoming greater and greater; and the masses of the people's demands on the quality of the ecological environment are bound to become higher and higher. In the long run, the contradiction between economic development and population, resources and environment will become more and more prominent, and the pressure on sustainable development will become greater and greater.

The total amount of natural resources in China is large, but due to the large population base in China, the population is growing too fast, and the per capita share is getting smaller and smaller
Therefore, c

The reason is that the Chinese population is large, so there are few resources per capita.

The population of our country is constantly increasing and numerous.
