There are various classifications of environmental pollution:

According to environmental elements: air pollution, water pollution, soil pollution.

According to human activities, it is divided into industrial environmental pollution, urban environmental pollution, and agricultural environmental pollution.

The Songhua River in my hometown was polluted with benzene from the Jilin Chemical Industry.

This is ironclad evidence of the pollution of the water body of the Songhua River.

Background of the storyDecades ago, a song "Volga Boatman's Song" spread to China. Its touching melody and beautiful lyrics deeply tug at the heartstrings of the listeners. Since then, the name Volga has been deeply imprinted in the minds of Chinese.

Recently, however, news came that the Volga River, which the Russians call the "mother river," is so polluted that the water surface of some sections of the river is even covered with oil splashes, and the fish and shrimp in the river have died one after another, and the "mother river" is on the verge of "death." The Volga, known as Europe's largest river, originates in the Valdai Hills northwest of Moscow and winds southward, covering an area of 1.36 million square kilometers and a total length of 3,690 kilometers. It is like a large tree with flourishing branches, nourishing about 1 3 of the European regions of Russia, and 1 4 of the population of all Russia.

For example, the Volga River, known as the "mother river", has been having a hard time lately, and it receives nearly half of Russia's industrial wastewater. These effluents contain not only domestic waste, heavy metals and their compounds, but also radioactive substances, organic poisons and oils. As a result, the people in the Volga River basin are facing the crisis of water shortage.

Today, water pollution is already very serious. It is said that more than 420 billion cubic meters of sewage are discharged into rivers, lakes and seas every year, polluting 5.5 trillion cubic meters of fresh water, accounting for more than 14 percent of global runoff, and it is currently on a worsening trend. According to experts**, the world's sewage discharge will increase to 16000 2.1 trillion cubic metres by 2000, and water resources will be even more polluted.

Water pollution is a serious threat to human health. Domestic sewage often contains many deadly viruses, germs and parasites. Once this pathogen-containing sewage contaminates drinking water sources and enters the human body, it can quickly cause various diseases, such as dysentery, diarrhea, typhoid, hepatitis, cholera and other infectious diseases, which in turn lead to a large number of deaths.

Diarrhoea and other diseases caused by unsafe drinking water kill millions of children each year, according to a report from the United Nations Children**. Drinking water is contaminated with heavy metal ions and toxic organic matter, and the consequences will be even more terrible. Water contains various heavy metal ions and organic matter that are difficult to decompose, including phenols, cyanide, mercury, chromium, arsenic, lead, cadmium, etc., which are extremely harmful to the human body.

These substances can cause malformations, cancer, and organ lesions in people. Minamata disease and pain disease are the most typical examples of this.

Fossil energy has been excessively exploited, forests have been excessively deforested, wetlands have been greatly destroyed, rivers have been polluted on a large scale, and the air has been seriously polluted. The diversity of species is disappearing rapidly, and in general, all resources are being destroyed to a certain extent.

It can be said that it has never been broken, and the destruction that we have no choice but to hear is only some understandable traces left by people in their own homes, which is not surprising

Mineral resources and so on have been destroyed、、、
