Abstract

Air pollution is an environmental problem that is familiar to residents of absolutely all corners of the earth. It is especially acutely felt by residents of cities where enterprises of ferrous and non-ferrous metallurgy, energy, chemical, petrochemical, construction, pulp and paper industries operate. In some cities, the atmosphere is also severely poisoned by vehicles and boiler houses. These are all examples of anthropogenic air pollution. The subject of the study is the emissions of carbon dioxide into the environment. The purpose of the study is to solve the problem of environmental pollution by harmful substances and preserve the ecology in the world. Methodology. The main indicators characterizing the impact on the environment - CO2 emissions in the global energy sector - have been systematized; two indicators have been identified that determine the level of atmospheric pollution. Results - the scale of the influence of atmospheric air pollution on human health and the entire ecosystem as a whole was revealed.

Highlights

Continuous technological progress, the continuing enslavement of nature by man, industrialization, which has changed the Earth's surface beyond recognition, have become the causes of the global environmental crisis
The world's population is acutely faced with such environmental problems as air pollution, ozone layer depletion, acid rain, greenhouse effect, soil pollution, pollution of the world's oceans and overpopulation
Air pollutants are conventionally divided into 2 types: natural and anthropogenic

Summary

Introduction

Continuous technological progress, the continuing enslavement of nature by man, industrialization, which has changed the Earth's surface beyond recognition, have become the causes of the global environmental crisis. The world's population is acutely faced with such environmental problems as air pollution, ozone layer depletion, acid rain, greenhouse effect, soil pollution, pollution of the world's oceans and overpopulation. As for the natural sources of chemical elements that pollute the atmosphere, they include forest fires, volcanic eruptions, wind erosion (dispersal of soil and rock particles), the spread of pollen, evaporation of organic compounds and natural radiation. The average person inhales about 20,000 liters of air, which contains, in addition to vital oxygen, a whole list of harmful suspended particles and gases. Air pollutants are conventionally divided into 2 types: natural and anthropogenic. The latter ones prevail [4]
