With the growth of population and rapid economic and social development, the problem of water resources, especially the contradiction between water shortage and economic and social development, has been fully exposed. The average annual area affected by drought in the country is about 400 million mu. In a normal year, there is an annual water shortage of 30 billion cubic meters in irrigation areas across the country and 6 billion cubic meters in urban areas.
At the same time of water shortage, there is also a serious waste of water, most of the national agricultural irrigation water use coefficient is only, and many countries have reached it; The water consumption of China's industrial output value per 10,000 yuan is 103 cubic meters, which is 10 20 times that of developed countries, and the reuse rate of water in China is about 50%, while that of developed countries is more than 85%. Water pollution is serious, with the total annual sewage discharge in the country reaching nearly 60 billion tons, most of which is directly discharged into the water without treatment. Of the more than 700 important rivers surveyed and evaluated nationwide, nearly 50 percent of the river sections and more than 90 percent of the urban river waters are polluted.
Water pollution not only destroys the ecological environment, but also makes the problem of water shortage more serious.

Natural resources are divided into renewable resources and non-renewable resources.
There is no problem with the use of renewable resources within the scope of their recycling.
Non-renewable resources are precious, and they should be used where they should be, not wasted, and used up.
In this way, the human use of resources is completely compliant, but the fact ...
-
Yes.
The natural resources used by the exhibition practice activities are socially existent.
However, the source of resources refers to the fact that in nature, human beings can directly obtain the materials used in the production of stove collapses and life. It can be divided into three categories, one is non-renewable resources, such as various metals and non-metallic minerals, fossil fuels, etc., which need to go through a long geological time to form.

Natural resources refer to anything that is obtained from the natural environment and can be used by people in the form of celery and plum seeding Including renewable resources and non-renewable resources Biodiversity is the main feature of nature Natural resources are the basis for human survival and development This question is correctly described
So the answer is: true.

The three main characteristics of natural resources are scarcity, territoriality, and non-renewability. With these characteristics in mind, we should pay attention to the following when using natural resources:
1.Rational use of natural resources: Natural resources are scarce, regional and non-renewable, so we should pay attention to rational use in the use of natural resources. Waste, reuse and reuse as much as possible.
2.Consideration of ecosystem balance: The development and utilization of natural resources must take into account the balance of ecosystems in order to avoid damage to the ecological environment and damage to the ecosystem.
Strictly restrict the development of those that have a large impact on the ecosystem and damage to the natural ecosystem; The exploitation of other natural resources should also be carried out in a way that respects ecosystems and minimizes damage.
3.Prioritizing the development of renewable resources: Renewable resources are more sustainable than non-renewable resources, so priority is given to the development and utilization of renewable resources, especially new energy resources.
4.Strengthen the protection and preservation of natural resources: The protection and maintenance of natural resources should be an essential task. It is necessary to strengthen the protection and management of natural resources that have the value of protection, restrict their development and use, and prevent vicious occupation and damage.
In short, the use of natural resources should be based on the different characteristics of resources, with the protection of the ecosystem as the core, and priority should be given to the development of new energy, repeated use and reuse of Lizhou. Strengthen the management and exploitation of non-renewable resources, and at the same time strengthen the protection of natural resources, so as to ensure the balanced development of human economic activities and ecosystems.

Natural resources are the materials and energy that exist in nature and can provide welfare for human beings, mainly including agricultural resources, forest resources, climate resources, water resources, land resources, biological resources, mineral resources and marine resources
So the answer is: welfare is empty
-
Mineral deposits, water, atmosphere, forests, etc., are all natural resources.
The natural environment is related to the development of human society and can be used to generate use value and affect labor productivity.
The elements of nature, commonly known as natural resources, can be divided into tangible natural resources (such as land, water bodies, animals and plants, minerals, etc.) and intangible natural resources (such as light resources, heat resources, etc.). Natural resources are the material basis for human survival and development, the source of social material wealth, and sustainable development.
One of the important bases. Natural resources are divided into the following categories: biological resources, agricultural resources, forest resources, land resources, and mineral resources.
Marine resources, climate and meteorology, water resources, etc.

Answer c Natural resources are the foundation of the development of human society, and the development process of human society is also the process of development and utilization of natural resources. Reference.

Do whatever comes to mind, and make the most of your own initiative, regardless of the eyes of others. The premise is to go through the brain.
Thought is based on the tangible world, (explain, what is left of our mind other than what we hear, see, feel, smell and taste?) The universe constitutes our existing tangible world, so the mind cannot transcend the universe. The universe increases or decreases according to the desires of thought, for example, in the past, scientists used molecules as the elementary particles of matter, and matter was made up of molecules. >>>More
