From the current environmental point of view, what is the source of the biggest pollution?

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?

Sewage, waste tung gas, garbage, noise, light pollution, etc., are common pollution in cities.

2. Air: industrial exhaust, automobile exhaust, household kitchen fumes, pesticides, new plastic products, refrigerator Freon and various garbage, waterway gases.

3. Noise: household noise, traffic noise, construction noise, social guessing noise (hawking, firecrackers, store sound, etc.).

4. Light: visible light, laser, infrared light, ultraviolet light, etc.

5. Food: additives, artificial colors and pesticides.

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 of farmland after irrigation 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; The main pollutants in the air are sulphur dioxide, nitrogen oxides, particulate pollutants and acid rain.
