There is no need to "feel" this question. The biggest source of environmental pollution is industrialization. In the industrial age, white garbage, sewage, heavy metals and harmful gases have caused all-round pollution to soil, water resources, ocean and atmosphere, and this pollution will take a long time to recover on the earth itself. There was a joke circulating on the Internet. After several years, when children and grandchildren were digging underground, they were no longer digging unearthed cultural relics, but all kinds of garbage that had not been digested by the earth.

Let's talk about the direct pollution of industrialization to land. We don't need to analyze all kinds of industrial waste. We just need to look at the plastic bags we use every day, from small mountain villages to cities with tens of millions of people. There are thousands of plastic bags used by a person in his life, and the world population is 7 billion. If per capita 1000, the number of terror can be imagined, plus other plastic products, washbasins, plastic buckets, plastic furniture and so on. Although the current garbage disposal technology can reduce the time to repair the earth, and many countries are also advocating to reduce the use of garbage bags, the successive changes in population will one day exceed the carrying capacity of the earth, and the people themselves will be affected.

Besides, the pollution of water resources, the more developed the industry, the more serious the groundwater pollution, such as Haihe River Basin and Liaohe River Basin in China. Similarly, we don't need to count the figures of industrial sewage discharge, just look around us. Once the underground well water was dug out, it can be directly drunk, which is not only sweet but also rich in trace elements. At present, heavy metals and chemical elements in groundwater generally exceed the standard, and even the color of groundwater in heavily polluted areas is no longer transparent. Drinking such groundwater for a long time has brought many diseases to people of all ages.

In addition, at present, some farms also have groundwater pollution, and the source also points to industrialization, because at present, large-scale farming uses industrial feed, regardless of chickens, ducks, cows and pigs. This feed not only comes from natural plants, but also contains many chemical additives. Eventually, these chemical elements will be discharged into rivers with feces, affecting groundwater.

Finally, air pollution is relatively simple. I believe that people living in cities have seen chimneys of thermal power plants and chemical plants. Theoretically, the treated harmful gases do not pollute the environment so much, but there are always some enterprises that secretly discharge them, especially at night, which is the worst. Like the industrialized cities in China, such as Zibo, Xi, Shaanxi, Taiyuan, etc. At night, you can hardly see the stars. If you want to see the stars in the sky, you can only go to the countryside.
