Abstract: in this article main causes of atmosphere pollution and some opinions on how to prevent them are given. Moreover, its results and future predictions are explained. The atmosphere is one of the main sources of life in the biosphere, which covers the Earth's surface. The atmosphere protects all living things from harmful cosmic rays. We also gave some examples.
Keywords: protecting the nature, natural resources, artificial resources.

Аннотация: в статье приводятся основные причины загрязнения атмосферы и некоторые мнения о том, как их предотвратить. Более того, его результаты и будущие прогнозы объясняются. Атмосфера является одним из основных источников жизни в биосфере, которая покрывает поверхность Земли. Атмосфера защищает все живое от вредных космических лучей. Мы также дали некоторые примеры. Ключевые слова: охрана природы, природные ресурсы, искусственные ресурсы.
The atmosphere is one of the main sources of life in the biosphere, which covers the Earth's surface. The atmosphere protects all living things from harmful cosmic rays.
The atmosphere has been relatively stable for a long time, and in recent years there has been a dramatic change in gas balance due to the increase in human impact, which has led to the increase in the constant amount of gases in the atmosphere, resulting in negative consequences for the planet. The "greenhouse effect" suggests that changes in the average temperature of the earth lead to severe environmental consequences. Annually, more oxygen is consumed in the biosphere. When the biosphere resources re-establish oxygen supply, given the rapid decline in the green vegetation, it is clear that future oxygen diminishes.
Atmospheric pollution is the result of the addition of alien compounds to the air, changes in its physical and chemical properties, and the atmosphere is polluted in two ways:
1. Natural way
2. Artificial way.
Pollution of the environment on the basis of natural factors is primarily natural, such as lightning strikes, combustion of forests, volcanic eruptions, wind movements, biodiversity conservation (fossil and animal residues) processes. They emit millions of tons of dust per year.The sources of artificial pollution include energy, industrial enterprises, transport, household waste, and so on. At the present time, artificial

(anthropogenic processes) are most common in nature pollution. About two -thirds of the pollutant emissons into the atmosphere are caused by the anthropogenic factors and it is increasing. Furthermore, the concepts, such as the increase in the number of the population, the usage of pesticides in agriculture and the rubbish are also considered contributing factors to the air pollution.
Pollution of land (lithosphere) occurs as a result of the extraction of minerals, especially in open cast mining. Soil, in particular, exposed them openly. The soil is polluted especially by industrial and agricultural waste. The main pollutants are various metals and their compounds, mineral resources, chemical poisons, and radioactive substances. Disposal of waste caused by household and livestock wastes leads to deterioration of sanitary and hygienic conditions.
The smoker (smokes and smoke mixes), which are observed in some areas due to the lack of air, can have an adverse effect on human health. Smog prevention is important. In order to reduce the air pollution on the Earth, the necessary precautions must be taken immediately.
Atmospheric air pollution results in various socio-economic consequences. The deterioration of human health, the destruction of buildings, historical monuments, the destruction of plants and animals, and other events have major economic damages. Atmospheric air is self-purifying. But it's limited. The elimination of high levels of man-made contamination is a must for people to do.
At present, the share of motor transport increases in air pollution. More than 500 million cars worldwide produce hundreds of thousands of harmful compounds daily. There are more than 200 harmful compounds in the vehicle smoke, including lung cancer and other serious diseases. More than 70 percent of air pollution in Tashkent is due to the motor transport.
Atmospheric air pollution in the Republic of Uzbekistan is one of the major environmental problems. The fact that the cities are located mainly in the foothills and slopes, the hot and dry climate has led to a relatively high level of atmospheric air pollution in Uzbekistan. Atmospheric air in Uzbekistan is particularly contagious in the Tashkent and Fergana economic regions, where the population, industry and transportation are highly concentrated. Some of these cities, which are susceptible to a number of hazardous compounds, are at risk of photochemical smog.
The atmosphere is polluted by electricity, metallurgy, chemicals and other industries, vehicles, spacecraft, or various fires. As a result, billions of tons of solid, gaseous, aerosol waste is released every year. Increased emissions of atmospheric gases (CO) and sulfuric gases (SO2) in the atmosphere have led to great environmental problems. Indeed, the heating regime of the solar system began to decline as the atmosphere was exposed to pollution by various types of aerosol gases, such as, sulfur, nitrogen, fluorine-chloride, phosphorus, brown, mercury, aluminum. In turn, this can lead to climate change, gradual erosion of eternal glaciers on the planet pole and high mountains.
Over the last few years, more and more extraction of fluorine-chlorine compounds into the air has resulted in a gradual decline in the ozone layer, the shield of life on Earth. This phenomenon, called the ozone hole, was first seen in South America's Antarctic boundaries, and in recent years, on the northern latitude of Eurasia. The origin of these problems is largely due to environmental degradation and environmental pollution. Improper use of natural resources, environmental pollution leads to an ever-increasing vacuum environment. This, in its turn, puts on complicated tasks, such as taking measures against the society.
