How should human beings make rational use of the earth s resources?

There are two types of resources on the earth, renewable resources and non-renewable resources. Renewable resources such as solar, wind, hydro, etc., are used until the earth does not exist. And non-renewable resources, such as minerals, bioenergy, etc., are gone when they are used up.

Non-renewable resources restrict the use of renewable resources, for example, a large number of human use of renewable resources must be completed with the help of non-renewable resources, solar water heaters are the use of solar energy, but with the help of silicon, iron, aluminum, copper and other non-renewable resources, therefore, should be rationally used to protect the earth's environment, protect human beings, and ensure that there are no extreme events.

For example, the use of solar energy, to ensure that the infrastructure does not occupy an area, does not occupy human living space, so solar water heaters, silicon panels are built on the roof of buildings or in the air or in places that are difficult for humans to reach. Wind energy is used, in less populated areas and where the wind is stronger. The utilization of mineral resources needs to be saved, the well-known fact is that the operation of a large number of rapid transportation vehicles are borrowed from the internal combustion engine, not to mention that the internal combustion engine burns oil, the material of the internal combustion engine itself, there are many metals and rubber, these are consumables.

In addition to saving, there should also be **. ** Consumed resources can then be reused. Needless to say, this is not much to say.

The third is to develop new resources. The so-called new resources are actually resources that have not been discovered or used by human beings, and they are also natural resources. For example, a large area of the earth is water, and it is not new to use water to generate electricity, and now human beings are developing seawater, decomposing seawater into hydrogen and oxygen, recombining these two types of gases, and using the heat energy generated by them, and the product of the synthesis is water, which can also be decomposed and reused.

If successful, this is the best renewable energy for humanity. However, the use of such energy sources is still constrained by non-renewable resources.

Therefore, the most rational way to use resources is to economize.

The theme has breadth and depth, and on a macro level, different resources have different ways of utilization, mainly by using "scientific" methods, through a large number of micro experiments, with the aim of continuous recycling, maintaining the living environment of human beings, and benefiting human development. According to the law of conservation of material energy, the energy resources on the earth can be used by human beings until the earth dies, but if you don't pay attention to the way and way, it can only be self-defeating. Example 1, human beings have discovered that nuclear fission will produce a chain effect and huge energy, and it is a scientific utilization method to use this resource energy for power generation, transportation, processing and other projects.

Example 2, water is the basic component of life, can also be said to be the source of life, the use of water at the same time we should take into account other natural factors and artificial factors that are not conducive to the existence of fresh water, take measures, this is also a reasonable and scientific way of use. There are also coal, oil and natural gas, etc., which need to be used in a specific scientific way, and can be implemented through legislation, advocacy, publicity, education or compulsion. (All belong to material resources) and other resources are not in the analysis.

1.Control the population.

2.Save energy.

3.Development of new energy sources.

First, the evaluation of regional natural resources;

second, the regional demand for natural resources;

third, the sustainable development of natural resources through development and utilization;

Fourth, the understanding of the characteristics of regional resources.

The use of human resources began with the emergence of human beings, from the use of stone by primitive people, to the use of copper, and then to the use of iron. Later, the use of energy, and now the use of rare and scattered metals, as well as the large use of energy and bulk minerals. It is due to the development of society and the comprehensive utilization of certain minerals or certain minerals at different stages.

The subject may ask this question because he thinks that human beings are using a lot of resources, for example, oil, at the current rate of use, and with the proven oil reserves, it may not take a few hundred years. Truly. You have such doubts and worries now, but you don't really have to worry at all.

Let me tell you how human beings use resources.

Clause. 1. In feudal society, people were very scarce about iron, kerosene and other resources, because they felt that these things were very scarce at that time. Later, due to the development of science and technology, a large amount of iron ore was discovered.

Iron ore is $50-120 t, which is really cheap. The use of coal, wind, solar, and geothermal energy has basically made kerosene a thing of the past. Therefore, with the development of science and technology, when human beings use a certain resource, due to profit and other reasons, human beings will look for more energy-saving, practical and cheap resources.

For the use of resources, human beings know that such resources are scarce, and then use a large number of them, human beings will definitely find a more suitable resource to replace. For example, like the previous computer, some of the accessories in it require a lot of gold. With the development of science and technology, mankind has found another metal to replace it.

There is also the use of oil, which is now decreasing year by year, and it is expected that around 2040, the global use of oil will peak, and in turn, natural gas will replace oil in some ways.

Clause. Second, the first utilization has become another way of resource regeneration, such as the first utilization of scrap iron, so that the speed of iron ore mining is reduced.

Clause. 3. At present, space mining majors have been set up abroad, with the aim of finding mineral resources outside the earth, which can come in handy at some point in the future. But for now, space mining is not yet suitable for market promotion due to the extremely high cost.

When the earth runs out of resources, human beings will develop new resources, such as the use of solar energy, which is a new source of energy.

If the earth has no resources, human beings may become extinct, because the degree of human dependence on resources is very high, and the earth may also be destroyed.

Human beings may become extinct, because without resources, human beings will not be able to maintain normal life and work, and the biological chain will be completely broken

Humans can choose to leave some resources behind and then re-store them and live on technology.

Mineral resources. Such as iron, gold, oil, etc., these effects on human beings are self-evident.

Energy resources. Such as wind energy, tidal energy, geothermal energy, etc., these are indispensable energy sources for human beings now and in the future.

Ecological resources. Such as flowers, trees, insects, fish, birds and beasts, the ecological balance will keep the earth's climate stable, which is the reduction of natural disasters for human beings.

Among these resources, mineral resources are non-renewable resources, and overexploitation will greatly threaten the future development of mankind. Energy resources are renewable resources that can be reused and produced. If the ecological resources are not properly protected, the change of lead can be regarded as a non-renewable resource.

If it is used and conserved wisely, it can be regarded as a renewable resource. Among them, water resources can be considered as renewable resources.

1. Save water.

Water is the source of life, and without it, human beings cannot survive. After the water is used, the faucet should be tightened in time, and some water can be reused in Shanyanzheng, such as rice washing water.

It is used to wash dishes to remove grease stains, and the water used to wash clothes can be used to wash mops ......This saves a lot of water.

2. Classification of domestic waste.

Many countries are advocating and implementing the classification of domestic waste, which can lead to some reusable waste products, such as newspapers and beverage bottles.

etc., and if it cannot be processed, it can reduce pollution and create other values, such as cardboard can be reprocessed and reused.

3. Save electricity.

When the appliance is not in use, in addition to turning off the power, you must remember to unplug it, because even if the power is turned off, there will still be power consumption. The temperature of the air conditioner should not be turned on too low, the light bulb should be energy-saving lamps, and the model with the lowest energy consumption should be chosen when purchasing new electrical appliances.

4. Refuse disposables.

Carry a basket or shopping cart when shopping for groceries.

Don't want those blue and green plastic bags, which are extremely difficult to degrade. Don't use disposable chopsticks when you go to a restaurant to eat, you are saving the tree. Replacing napkins with handkerchiefs is also to reduce the felling of trees.

5. Love animals.

Refuse to eat wild game and protect wildlife.

It is to protect humanity itself. The most important thing for wild animals is not only to refuse them to serve the table, but also to protect them from interfering with their normal life, and to protect the ecological balance. According to studies, the nutritional value of wild animals is no higher than that of ordinary meat.

In addition, wild animals are carriers of germs that have not been quarantined, and they are susceptible to diseases, so it is better not to eat them.

6. Protect greening.

Protect green vegetation, protect every grass, tree and flower, don't step on the lawn casually, love green, and protect green plants from being destroyed. If there is vacant land, you can buy saplings to plant and take care of the saplings. This is not only good for health, but also purifies the air, brings greenery to the earth, and makes the earth we live on more beautiful.

7. Develop energy-saving innovative products.

Around the world, energy-efficient technologies are embraced not only as a smart and cost-effective way to protect the planet, but also as a way to salvation. from phasing out incandescent lamps.

From the implementation of technologies that meet ENERGY STAR standards to reduce energy consumption in standby mode, consumers, manufacturers, and ** are all working in unison to help build an energy-efficient society.

8. Save energy.

Save every drop of water, water should be recycled, reused, and don't make your tears the last drop of water on the earth; Every grain of grain, "who knows that the Chinese food on the plate, every grain is hard"; Save electricity, turn off the lights and electrical appliances at will, turn off the electrical appliances when you don't use them, and try not to be out of standby mode.
