ENVIRONMENTAL PROBLEMS.
PLAN:
1. Composition of environmental problems.
2. Global environmental problems and their consequences.
3. Regional and local environmental problems.
Currently, the biosphere is changing very rapidly under the influence of human activity. It was emphasized by VIVernadsky that man appeared as a great geological force in changing the face of the Earth. As a result of man's misuse of natural processes, environmental problems became very serious in the middle of the 20th century. Ecological problem means the negative impact of nature on man in connection with the influence of man on nature, i.e., processes of economic importance in his economy, life, and all related to natural phenomena ^. what event is understood. (climate change, mass migration of animals) ecological problems of various scales are formed due to disturbance of balance in nature. They can be divided into the following groups.
1 Global (universal).
2 Regional (regional).
3 Local (local).
Global environmental problems occur as a result of natural, natural anthropogenic and purely anthropogenic effects observed around the world and belong to the whole world.
Let's get acquainted with some of these environmental problems: The phenomenon of atmospheric condensation. In recent years, it has become known that the amount of S0 ₂ in the atmosphere is increasing. As a result, the temperature of the Earth's surface has increased by 0.5-1.0 degrees in the last 100 years. Climate change is largely caused by industrial emissions and vehicular emissions. Global warming of the Earth's surface, that is, the warming of the atmosphere, is due to the accumulation of S0 ₂ gas in the atmosphere from the increase in the composition of S0 ₂ in the air, deforestation, and the burning of fuels such as coal and gasoline . If the situation does not change, the temperature of the earth's surface may increase by 1.5-4.5 degrees in the middle of the 21st century. As a result:

1. Climate change, especially increased desertification. Changes in precipitation. Rising sea and ocean levels Melting and shrinking glaciers and other phenomena are observed.
