What are the main sources of environmental pollution? How to protect the environment?

The main sources of pollution are exhaust gas, sewage, industrial waste, chemicals and household waste.

We should control the emission of exhaust gas and wastewater, promote sustainable development, rational use of chemical substances, and dispose of industrial waste and household waste.

Industrial three wastes, domestic sewage.

Therefore, to protect the environment, we all need to enhance our environmental awareness, and we must save water on a daily basis.

Don't take out garbage in the river.

Therefore, it is necessary to write about the management of paper mills and other pharmaceutical factories that are very polluting, so we also need certain measures from the state.

I hope that you will not use disposable handy bags and chopsticks too often.

Domestic garbage, automobile exhaust, packaging bags, factory sewage, etc., it depends on the specific place, and it is necessary to control domestic garbage and other pollutants, but this is easy to say but difficult to do, and it must be done everywhere.

The main thing is energy pollution, but it is humans who are responsible for this consequence. There is only one way, and that is to make all mankind aware of this. Try to minimize pollution, if you have a calling.

Let's make a ** appeal. Let's make the international community appeal. is the most fundamental

This problem does not need to be "felt", the biggest source of environmental pollution is industrialization, white garbage, sewage, heavy metals, harmful gases, etc. in the industrial age, which has caused all-round pollution to the soil, water resources, oceans, and atmosphere, and this pollution depends on the earth itself It takes a long time to recover, there has been a joke on the Internet that when the children and grandchildren dig underground after a few years, what is unearthed is no longer cultural relics, but a variety of garbage that has not been digested by the earth, and there will be multiple garbage islands on the surface of the ocean.

Let's talk about the direct pollution of the land by industrialization, we don't have to analyze all kinds of industrial waste, just look at the plastic bags we use daily, as small as mountain villages, as large as tens of millions of cities, thousands of plastic bags used by a person in his life, 7 billion people in the world, calculated by 1000 per capita, then the terrifying number formed can be imagined, plus other plastic products, basins, plastic buckets, plastic furniture and so on, the pollution number is even more terrifying. Although the current garbage disposal technology can reduce the time for the earth to be repaired, and many countries are also advocating the reduction of garbage bag use, the population will change one after another, and sooner or later it will exceed the carrying capacity of the earth, and it will be human beings themselves who will be affected.

In addition, water pollution, the more industrially developed areas, the more serious the groundwater pollution, such as the Haihe River Basin and the Liaohe River Basin in China. There is also no need to count the number of industrial sewage discharge, just look at our surroundings. Once the underground well water dug out can be drunk directly, not only sweet and rich in trace elements, but now the groundwater is generally heavy metals, chemical elements exceed the standard, and even the color of the groundwater in the seriously polluted area is no longer transparent, long-term drinking of such groundwater, to people of all ages have brought a variety of diseases.

In addition, like some current farms, there is also groundwater pollution, the source also points to industrialization, because the current large-scale farming, whether it is chickens, ducks or cattle and pigs, will use industrial feed, this kind of feed is not only taken from natural plants, there are many chemical additives, and eventually these chemical elements will be discharged into the river with manure, affecting groundwater.

Finally, air pollution, this is more straightforward, I believe that people living in the city have seen the big chimneys of thermal power plants and chemical plants, theoretically the treated harmful gases are not so big for environmental pollution, but there are always some enterprises that will secretly discharge secretly, especially at night, taking advantage of the night to directly emit the most serious polluting gases. For example, China's industrially developed cities, such as Zibo in Shandong, Xi'an in Shaanxi, Taiyuan in Shanxi, etc., can hardly see the stars at night, and if you want to see the stars in the sky, you can only go to rural areas.

At present, the biggest source of pollution is plastic products, and the number of plastic products is increasing, and the harm to the natural environment is also very great.

The main pollution is carbon dioxide emissions, and this problem must be solved in order to make the environment better.

The source of environmental pollution is that the tailings of gold mines and tailings ponds are full of sand, dust, and serious environmental pollution, and the people cannot live normally.

It's human beings, human beings who make garbage all the time, and human beings don't protect the environment, they don't pay attention to environmental sanitation.

Why let people's cars be restricted to odd and even numbers?

It should be: industrial pollution sources, agricultural pollution sources, transportation pollution and domestic pollution sources.

According to the attributes, it can be divided into natural pollution sources and man-made pollution sources.

According to the type of emission pollution, it can be divided into organic pollution sources, inorganic pollution sources, thermal pollution sources, noise pollution sources, radioactive pollution sources and mixed pollution sources that emit multiple pollutants at the same time.

According to the main objects of pollution, it can be divided into air pollution sources, water pollution sources and soil pollution sources.

According to the function of human society, it can be divided into industrial pollution sources, agricultural pollution sources, transportation pollution and domestic pollution sources.

There is marine pollution all around us

Environmental problems such as light pollution, air pollution, and land pollution. The main cause of environmental pollution is the human factor, in ordinary life people excessive cutting down of trees, hunting animals, emitting a large amount of industrial waste gas, waste and other bad habits caused by environmental pollution.

Marine pollution refers to the discharge of harmful substances into the ocean by human beings, destroying the marine ecosystem and causing pollution. This not only harms the resources of marine life, but also endangers human health. Light pollution is the "light" of books, paper, and paint on the wall in ordinary life, which is seriously harmful to the human body.

It can cause dizziness to pedestrians during the day and discomfort to the body at night.

Air pollution is mainly divided into natural factors and man-made factors. The human factor is the main reason. Carbon dioxide emitted from the exhaust of a car while driving in daily life.

Exhaust gases from industrial production and fuels from daily life are the causes of air pollution. Land pollution is the discharge of harmful substances into the soil by humans, and after a certain accumulation, it leads to changes in soil properties and quality. Air pollution has certain hazards and impacts on crops and human health.
