1. The proction cycle of mineral resources is generally more than 50 million to 100 million years, and the continuous excavation of human beings will certainly become less!
2. Shortage: rapid economic development, large consumption, less per capita resources, in addition, excessive development, and unplanned development
measures: the development and utilization of resources in China is not reasonable and scientific, with serious waste and loss. Rational development and utilization of resources, adhere to both development and conservation, and put conservation in the first place
consequence: as mineral resources are exhausted, the use of non renewable resources must be controlled; 2、 Waste, over exploitation, most of them are in the form of extensive, so the efficiency of utilization is generally not very high; 3、 Pollution, mineral mining will generally bring pollutants from the ground to the surface, such as sulfur, which has an impact on the atmosphere, water and land;
3. With the depletion of mineral resources, many self-supporting instries will be transformed into import-oriented instries. The rising prices of raw materials will lead to the rise of domestic prices, which will have a great impact on the market. Secondly, the rection of mineral resources will make many instries unable to proce normally or even close down, which will bring a lot of inconvenience to our lives. Generally speaking, once raw materials need to be imported, it means that China's development will be subject to many restrictions.

However, with the continuous exploitation and development of human beings, some mineral resources are facing exhaustion. Based on the understanding of the properties and uses of rocks and minerals, this course aims to understand the relationship between rocks, minerals and us from the perspective of resource depletion, so that students can realize that science has brought some negative effects on human beings while it is developing continuously, and realize the double-edged sword role of science and technology. The textbook is divided into two parts: the first part introces the mining activities of rocks and minerals, which lead to the depletion of mineral resources. First of all, show a group of pictures to let students realize that mineral resources are constantly mining, and show the real ruins left after mining, which makes people feel sad. Then, the textbook provides the depletion schele of some mineral resources (200 years of coal, 40-50 years of oil, 40-30 years of iron ore, 20-30 years of silver, zinc, mercury, lead and sulfur in the middle of the 21st century), which enables students to realize that mineral resources are constantly decreasing, and they are non renewable resources. Today, if we use more and exploit more, we will rece them, and our children will use less If we don't use it sparingly, what kind of world will our children and grandchildren live in. The second part introces the human efforts to protect rock and mineral resources: slowing down the process of mining and developing new energy. The textbook introces the situation of human using wind energy, solar energy and water energy, so that students can realize that wind energy, solar energy and water energy are inexhaustible, inexhaustible energy, safe and pollution-free, and they are the cheapest energy. Finally, from the perspective of students, we put forward: as students, what can we do for the protection of mineral resources? Arouse students' deep thinking and extend the classroom to extracurricular. Teaching objective: process and method: be able to investigate and understand the relationship between rocks and minerals and us. Be able to access and collect information about new energy sources. Scientific knowledge: know the positive and negative effects of human mining activities on resources and natural landscape. Understand the importance of protecting rocks and minerals. Emotional attitude and values: we realize that human development has destroyed the environment and consumed resources at the same time. We should make rational use of mineral resources and develop new energy. Teaching preparation: Teacher: pictures of rock and mineral exploitation, timetable of partial resource depletion, pictures of wind energy, bioenergy, tidal power generation, solar energy, geothermal and other new energy. S: collect pictures about new energy sources. Teaching process design: 1. Talk about the use of rocks and minerals in connection with the reality of life. 1. Narration: some time ago, we have learned the characteristics of rocks and the properties of minerals. When people master their characteristics, they will use them in life. Please contact life and think about the role of rocks and minerals? 2. Students talk about the role of rocks and minerals in daily life Comment: constructivism holds that students are not a blank sheet of paper before entering school, but bring their own life experience and direct views on some problems. In science class, it is necessary to fully mobilize students' known experience, and integrate the teaching content in science class with students' known experience, so as to truly form students' own things. Students will come into contact with a lot of knowledge about the use of rocks and minerals in their life. They will bring some phenomena in their life to science class, which is called "coming from life", or "coming from life". Then they will explain these phenomena through a series of discussions and experiments, and apply what they have learned to life to improve people's quality of life, which is called "going to life", It's also called "higher than life". Science class is "coming from life and going back to life." 2、 This paper introces the mining of rocks and minerals, which leads students to realize that some mineral resources are facing depletion. Question: since rocks and minerals have so many uses, how are they mined? Lead the students to talk about the mining methods of minerals from the mining of coal, oil, iron ore, etc. the teacher shows some pictures on camera, and then adds some mining methods of minerals, such as gold panning Note: this part is not the focus of teaching, only requires students to understand it.) 2. Thinking: after mining, what will the areas or surface look like Students may elaborate from the destruction of natural environment and the shortage of mineral resources. The teacher shows the ruins after mining and guides the students to think deeply: why does this happen? What do you think when you see this Students may think: This is e to over exploitation. This has brought great damage to the natural environment 3. Show some time table of mineral resource depletion to guide students to think further: what do you see from this table? What do you think? What do you want to say or some good suggestions The third level of thinking) causes students to appeal from the heart: we should make rational use of mineral resources, not over exploitation Comment: three levels of thinking, from the outside to the inside, from the phenomenon to the essence, graally deepen. From the pictures of mining to ruins, to a group of grim data, the students' hearts are shocked. This kind of shock touches the soul, not moans without illness.) 3、 How can we solve the contradiction between human needs and the shortage of mineral resources? 2. Group discussion, report and exchange 1) Reasonable use, slow down the speed of mining (2) continue to develop new energy. 3. Students report the information of new energy collected before class in an appropriate way Comment: science curriculum standard requires students to choose the way they are good at (language, text, chart, model, etc.) to express the research process and results. At the same time, the specific objectives of the outline of basic ecation curriculum reform (for Trial Implementation) clearly require the cultivation of students' ability to collect and process information.) 4. Teachers introce some new energy. 5. Discussion: the advantages of these new energy sources. Inexhaustible, inexhaustible, safe and pollution-free... Let students fully realize the importance of science and technology in improving human life
5. In order to punish the criminal activities of illegal mining and destructive mining in accordance with the relevant provisions of the criminal law, the interpretation of several issues on the specific application of law in the trial of criminal cases of illegal mining and destructive mining is as follows:

Article 1 illegal mining in violation of the provisions of the mineral resources law, Under any of the following circumstances, those who refuse to stop mining after being ordered to stop mining, thus causing damage to mineral resources, shall be convicted and punished with the crime of illegal mining in accordance with the provisions of the first paragraph of article 343 of the criminal law:

(1) mining without obtaining a mining license< (2) mining in the state planned mining areas, mining areas of great value to the national economy and other mining areas without authorization< (3) unauthorized mining of specific minerals that are subject to protective mining as stipulated by the state< (1) mining mineral resources without a mining license; and< (2) continuing to exploit mineral resources after the mining license has been cancelled or revoked< (3) mining mineral resources beyond the mining area specified in the mining license< (4) mining mineral resources not in accordance with the minerals specified in the mining license (except symbiotic and associated minerals); and< (5) other situations of mining mineral resources without mining license< Article 3 if the value of damage to mineral resources caused by illegal mining is more than 50000 yuan, it belongs to "damage to mineral resources" as stipulated in the first paragraph of article 343 of the criminal law; If the amount is more than 300000 yuan, it belongs to "causing serious damage to mineral resources" as stipulated in the first paragraph of article 343 of the criminal law< According to the second paragraph of article 343 of the criminal law of the people's Republic of China, "mining mineral resources with destructive mining methods" refers to the behavior of the actor who mines mineral resources in violation of the plan for the development and utilization of mineral resources examined and approved by the Department in charge of Geology and mineral resources and causes serious damage to mineral resources< Article 5 if the value of mineral resources damaged by destructive mining is more than 300000 yuan, it belongs to "causing serious damage to mineral resources" as stipulated in the second paragraph of article 343 of the criminal law< Article 6 destructive mining methods and the amount of damage or serious damage to mineral resources shall be determined by the appraisal conclusion issued by the Department in charge of Geology and mineral resources at or above the provincial level after verification

Article 7 If multiple illegal mining or destructive mining constitutes a crime and should be prosecuted according to law, or if multiple illegal mining or destructive mining has not been dealt with within one year, the cumulative amount of damage to mineral resources shall be calculated

Article 8 the standards of conviction and sentencing for units committing crimes of illegal mining and destructive mining shall be implemented in accordance with the relevant provisions of this interpretation

Article 9 the higher people's courts of all provinces, autonomous regions and municipalities directly under the central government may, according to the actual situation of their own regions, determine the starting amount standard for the implementation of Articles 3 and 5 of this interpretation within the range of 50000 yuan to 100000 yuan and 300000 yuan to 500000 yuan, and report to the Supreme People's court for the record.
6. 1. Improve the recovery rate
2, comprehensive utilization
3, the national macro-control, provide the cost of mineral resources utilization
7. There are also many alternative energy sources, although they are not mature enough to completely replace oil, natural gas and coal
for example, wind energy, solar energy, geothermal energy, tidal power generation, combustible ice, hydro power generation, nuclear energy (nuclear fission, nuclear fusion) and so on
the most promising is nuclear fusion, which is also the energy source of solar luminescence and heating, but it is still in the experimental stage
8. Excessive exploitation and waste are serious, some mineral reserves are small, rare and unproved minerals
the consequence is that the sustainable development cannot be realized, the follow-up construction is unbalanced, and the resources are completely exhausted
measures are taken to rationally develop and utilize the protective development and improve the technology of smelting slag
