Debate about environmental population capacity, the correct narrative about environmental population

It's a difficult question, and I hope it's not there yet, but the changing environment reminds us all the time that there are too many people.

Many times we always think that environmental pollution makes the environment worse, but does anyone think about it? "Today, when people are concerned about environmental protection, everyone will have a little bit of consciousness, even if they are only a little bit, they will care about our living environment, and the environment is still getting worse. "In the case of a large population base, a small point of pollution will increase the difficulty of treatment and increase the harm.

Population control is a prerequisite for a better environment.

To clarify, I love children, I have one son, but I would prefer to have two.

In terms of the environmental capacity of the population, the growth momentum of our developing countries is relatively strong, but from a global perspective, many places are far from reaching the maximum value of ecological quantity. The earth we have now is not a matter of the size of our population, but of our distribution. At present, China's grasp of family planning is not as tight as before, and the increase in the cost of childbirth and raising children will inevitably lead to self-discipline.

Even if one day the developing world is overpopulated, disease and war will solve the problem, although we do not want to admit it, time will tell.

Regardless of whether it is pessimistic or neutral, it is just a state of mind of people, whether it will exceed only one result, I believe in the facts, the facts tell us that if we do not take measures, it is inevitable that the population will be overcrowded.

It's not something you have to worry about, and you can't change the status quo.

bEnvironmental population capacity (environmental carrying capacity) indicates the maximum population load that can be sustained by the natural resources and environment that can be exploited. Compliant is b.

Answer: DThe environmental population capacity of a region is constrained by many factors, and resources, the level of scientific and technological development, the degree of regional opening to the outside world, and the cultural and living consumption level of the population have the greatest impact on it, among which resources are the primary factor restricting the environmental population capacity (it not only refers to arable land resources), because the survival of human beings depends to a large extent on the condition of resources, and the richer the resources, the more people can be supported.

The environmental population capacity of our country is 1.6 billion. In 1991, the Natural Resources Comprehensive Investigation Committee of the Chinese Academy of Sciences published a report on the production capacity and population carrying capacity of China's land resources, which believed that China's population carrying capacity should be controlled at a maximum of about 1.6 billion.

There is no upper limit. bai

Before the Qing Dynasty, the environmental population capacity of the Zhongdu Kingdom was 80 million people, and as soon as it approached or exceeded this number, wars would usually break out on a large scale. After the introduction of sweet potatoes, the Qing Dynasty had hundreds of millions of people at the time of its fall (note: most of these people were Han and still lived in the original Ming Dynasty's hometown, that is, the province of the Eighteen Elements of the Headquarters), and the fall of the Qing Dynasty was not due to the rebellion of the people who could not eat.

Based on this, it can be seen that if the population's demand for basic necessities such as water and food is assumed to maintain a certain level, the problem of "feeding" can be completely solved due to the progress of science and technology.

In the words of the family, I hope that the landlord can use people-oriented thinking to look at the problem of environmental population capacity dynamically, and do not blindly echo the family planning policy formulated above.

Population capacity is generally equivalent to environmental population capacity, and the reasonable population capacity is the smallest at any time.

The environmental population capacity is greater than the population reasonable capacity and is greater than the population capacity.

bEnvironmental population capacity indicates the maximum load on the population that can be sustained by the natural resources and environment that can be exploited. There are many factors that affect the capacity of the environmental population, such as the abundance of resources, the level of science and technology, the degree of economic development, the level of education and the level of consumption of the population. The consumption level was negatively correlated with the environmental population capacity, and the others were positively correlated with the environmental population capacity.

At a certain historical stage, due to the relatively stable technological level and resource base, and the little change in the level of living consumption, the environmental population capacity is relatively certain.

Environmental population capacity refers to the maximum number of people that a region can support in a certain environment, also known as population capacity, so they are equal. Environmental carrying capacity is a fundamental property of the environment, indicating the maximum intensity, scale and speed of human activities that the environment can withstand without harmful changes. environmental carrying capacity and population capacity theoretically.

C. Analysis of test questions: The size of environmental population capacity is affected by resource factors, scientific and technological factors, the degree of openness to the outside world, comprehensive living standards and other factors. The environmental population capacity of a place has a positive relationship with the possession of natural resources, a positive relationship with the level of science and technology, and an inverse relationship with the comprehensive living standard of local residents.

The environmental population capacity of a region is not only determined by local natural resources, but also by the ability of the local area to obtain external resources. In a certain period of time, the factors affecting the environmental population capacity are stable, and the environmental population capacity is relatively certain. The status of resources, the level of scientific and technological development, and the level of people's living and cultural consumption are changing, which determines that there is a certain uncertainty in the reasonable capacity of the environment.

The relative stability and uncertainty of the factors affecting the environmental population capacity determine that the certainty of the environmental population capacity is relative and the uncertainty is absolute. Resources are the primary factor restricting the capacity of the environmental population. Therefore, a, b, and d are incorrect, and c is the correct option.

Comments: This question is of average difficulty, mainly to test the students' understanding and analysis ability of the characteristics of environmental population capacity.

Answer C: Within a certain historical period, the environmental population capacity is relatively certain. Under the assumption that the technical level, the foundation and potential of resources are relatively stable and the degree of opening up to the outside world is relatively stable, and the population consumption level does not change much, the relative fixed-scale burial capacity of the environmental population can be estimated.
