Animals, humans. A clean set of life is needed

People and other animals need clean air, but due to the influence of human production, life and other factors, the global air pollution degree is becoming more and more serious, and the amount of air pollutants is large, and the main harm is sulfur dioxide; Nitrogen dioxide; Carbon monoxide; Inhalable particulate matter.

1) Industry: Industrial production is an important part of air pollution. There are many types of pollutants emitted into the atmosphere by industrial production, including soot, sulfur oxides, nitrogen oxides, organic compounds, halides, carbon compounds, etc. Some of them are soot, and some are gases.

2) Stoves and heating boilers: A large number of civil stoves and heating boilers in the city need to consume a large amount of coal, and the coal will release a large amount of dust, sulfur dioxide, carbon monoxide, and other harmful substances to pollute the atmosphere during the combustion process. Especially in winter, when heating, it often fills the polluted area with smoke and chokes people's cough, which is also a source of pollution that cannot be ignored.

3) Transportation: Automobiles, trains, airplanes, and ships are the main means of transportation in contemporary times, and the exhaust gases produced by burning coal or oil are also important pollutants.

In particular, the number of cars in the city is large and concentrated, and the pollutants emitted by the exhaust can directly invade people's respiratory organs, which is very serious to the air pollution in the city, and has become one of the main sources of air pollution in large cities. The exhaust gases emitted by automobiles mainly include carbon monoxide, sulfur dioxide, nitrogen oxides and hydrocarbons, and the first three substances are very harmful.

4) Smoke from forest fires.

Air pollution is mainly dust and harmful gases, dust can cause sandstorm weather, belongs to inhalable particulate matter, harmful gases include sulfur dioxide, nitrogen dioxide, carbon monoxide

So the answer is: sulfur dioxide; Nitrogen dioxide; Carbon monoxide; Inhalable particulate matter.

Clean water and air.

Oxygen in the air is necessary for all aerobic organisms. All animals need to breathe oxygen, as do the respiration of green plants. In addition, green plants use carbon dioxide from the air for photosynthesis, and air is almost the only carbon dioxide required by all plants**.

Water is an inorganic substance composed of hydrogen and oxygen, which is non-toxic and drinkable. It is a colorless and odorless transparent liquid at room temperature and pressure, and is known as the source of human life. Water is one of the most common substances on Earth.

72% of the Earth's surface is covered by water. It is an important resource for the survival of all life, including inorganic chemistry and human beings, and it is also the most important component of living organisms.

The shortcut that animals, plants, and human beings need to live on should be its environment, which is the most important thing.
