What is the essence of environmental pollution and what is the solution?

The essence of pollution is the adverse changes to the surrounding environment caused by any natural or human behavior, for example, we throw a piece of waste paper on the ground, volcanic eruptions make a large amount of volcanic ash into the atmosphere, etc., it can be said that human activities are changing the environment all the time, and the changes of the earth are also changing the environment, but the environmental ecology and other systems have a certain self-recovery ability to cope with and adapt to these changes, so the best solution is to make the degree of environmental change not exceed his self-healing ability. Or self-purification, but the development of human activities cannot be delayed, so the best solution is to imitate the restoration ability of the environment, and at the same time vigorously work on conservation and recycling.

Pollution is light and heavy, but relatively speaking, in the bus fart, the air in the carriage is polluted, but it cannot be said that the air on the earth is polluted. Environmental pollution, in fact, is the environment in which human beings or other living mirrors live in a certain area (air, water, soil, etc.). ) is affected.

The essence of pollution is that it affects the original environment of humans or other living mirrors before the waste degrades itself or is eliminated by nature.

The solution,-- environmental problems are unsolvable to human beings, haha, because the greedy nature of human beings is difficult to change.

The essence of environmental pollution is the retention of elements in space.

The best solution is the circular economy.

The reasons for the phenomenon of pollution first and treatment later in the process of modernization:

1. Enterprises are born profit-seeking, and the cost of environmental protection investment can be saved, and there is often a fluke mentality.

2. The local government clearly knows that many enterprises will cause pollution to the local environment, even serious pollution, but out of the pursuit of local economic development, or because of their demand for GDP speed, they have not been able to find a minimum balance between economic development and environmental protection.

3. Compared with the supervision of developed countries, there are considerable loopholes in our supervision. The current contradiction is that pollution first and then treatment is a "lack of prevention" treatment, and the cost of investment is bound to be too high, and the price paid is bound to be too large. Although the mode of pollution while controlling reduces the harm of environmental pollution to a certain extent, it cannot fundamentally change the passive situation of environmental protection.

First of all, the lag in people's understanding, the environment has a certain self-cleaning ability, and the early impact of environmental pollution is not obvious, and only the environmental damage to a certain extent will attract people's attention. Some polluters have a fluke mentality, hoping that others will control the pollution and control the pollution so that the pollution is within the scope of environmental self-cleaning.

Secondly, our country's system for environmental protection is not very perfect, and most of the system is aimed at pollution first and then treatment.

Reducing pollution again will put higher technical requirements on the operation of the enterprise, and the cost will increase accordingly.

The local government excessively pursues economic development, ignores environmental protection and governance, and does not strictly supervise and so on

Technological, economic and unfavorable factors of administrative supervision.

The cost of treatment is higher than the cost of sewage.

Environmental pollution refers to the natural or man-made destruction, adding a certain substance to the environment and exceeding the environment's ability to promote self-purification and cause harm. Or due to human factors, the environment is polluted by harmful substances, so that the growth and reproduction of organisms and the normal life of human beings are adversely affected. Due to the change of the composition or state of the environment due to human factors, the quality of the environment is reduced, which disturbs and destroys the normal production and living conditions of the ecosystem and human beings.

Environmental damage refers to the degradation of the ecological environment caused by the irrational exploitation and utilization of natural resources and the construction of engineering projects by human beings, and the related environmental effects derived therefrom, thereby adversely affecting the living environment of human beings. The consequences of environmental damage often take a long time to recover, and some are even irreversible.

This is the inevitability of social development, just like we will work overtime if we don't get sick, we must first solve the problem of food and clothing before we can consider the environment.

In the past, the country needed to develop, environmental awareness was not enough (probably the world began to pay attention to it after the publication of the silent spring), and the productivity was low, which led to waste of resources and environmental pollution.

On the other hand, the economic level is low, and food is the most important thing, so the governance of spending money is shelved; When the economy is developed, pollution control will be paid attention to and implemented.

However, we cannot go down this path, because resources are limited and non-renewable, and the current pollution control technology is highly developed, so pollution should be eliminated at the source, otherwise the price paid will be very high.

For the sake of political performance. Sacrificing the environment for GDP growth as capital for promotion. Then the following ** scrambled to follow suit.

The cost of governance is too high, which is not conducive to the early development of the enterprise.

In the early days, high-tech environmental protection technology was not something that enterprises could afford, nor could the state afford, and there was no such technology at all. If it is a large enterprise, it can afford it, and it also has this technology, but if he wants to use this technology in a newly developed country, the high cost, he can do it directly in his own country, and it is convenient to supervise and manage. Why go to your country that is just developing.

A newly developed country has no technology and no capital, so it needs to be polluted first. Besides, you haven't developed yet, and the people don't know the seriousness of the pollution, they only know that they don't have money, and that's the awareness of environmental protection.

The so-called ** for the sake of political performance, every country is like this, and there is no incompetence and corruption. Don't be angry about everything, treat things politely.

Mainly: water, soil, and air noise.

The types of pollution are different, the treatment methods are also different, the water is basically treated by the activated sludge method, and the soil pollution mainly includes microbial method, plant method, physical method, and chemical method; The atmosphere is essentially treated before it is discharged; The noise is mainly sound insulation, sound attenuation. I recommend you take a look at "Environmental Engineering" edited by Jiang Zhanpeng.

Environmental pollution can be divided into air pollution, water pollution and solid waste gas pollution according to the different states of pollutants. More detailed divisions include biological pollution, pesticide pollution, etc.

Environmental pollution not only brings harm to human health, but also has a () effect.

a.Heredity (correct answer).

b.Infect. c.Destruction.

The main sources of environmental pollution are as follows:

1. Waste smoke, waste gas, waste water, waste residue and noise discharged from the factory;

2. Waste smoke, exhaust gas, noise, dirty water and garbage discharged from people's lives;

3. Exhaust gases and noise emitted from vehicles (all fuel vehicles, ships, airplanes, etc.);

4. Water flowing out after irrigation of farmland with a large amount of chemical fertilizers, pesticides, herbicides and other chemicals;

5. Mine wastewater and waste residue;

6. Machine noise, electromagnetic radiation, carbon dioxide pollution;

7. The main pollutants in the air are sulfur dioxide, nitrogen oxides, particulate pollutants, and acid rain.

Extended Materials. Environmental pollution is the result of various polluting factors themselves and their interactions. At the same time, environmental pollution is also affected by social evaluation and has a social character. Its characteristics can be summarized as follows:

1. Public nuisance, environmental pollution is not affected by regional, racial, and economic conditions, and all are harmed.

2. Latent, many pollution is not easy to detect in time, and once it erupts, the consequences are serious.

3. Long-term, many long-term and continuous effects of pollution, endangering people's health and life, are not easy to eliminate.

4. Time distribution, the emission of pollutants and the intensity of pollution factors change with time.

Answer]: a, d

AD [Analysis] Geographical environment is a necessary condition for human beings' material life, which restricts social development through material production, and cannot directly determine the dispersed development and social nature of society. Therefore, AD is chosen.
