ECOLOGICAL PROBLEMS OF THE PRESENT TIME AND SOLUTIONS ABOUT THEM
Currently, as a result of human activity, drastic changes have occurred in the biosphere, and many environmental problems are arising as a result of these changes. Due to growth, science and technology development and increasing human needs, environmental problems have intensified.
We divide environmental problems into the following groups
1. Global (universal)
2. Regional (regional)
3. Local (local)
1. Global (universal) ecological problems can be defined as problems caused by natural and natural anthropogenic and purely anthropogenic effects observed around the world.
Let’s get acquainted with such problems
-island problem
– greenhouse effect
– fresh water problem
-problem of tropical and subtropical forests
-problem of tropical and subtropical forests
-ozone problem
– the problem of the decrease in the number of flora and fauna – the increase of carbon dioxide in the air
– excessive release of waste gases into the air
– world ocean pollution
– disappearance of fertile soil layer
– desertification
– increase of household waste – atmospheric pollution
– pollution of the lithosphere
– pollution of the hydrosphere – salinity
– the failure of pastures
THE ISLAND PROBLEM. The Aral Sea was considered one of the largest seas until recently. It was important for fishing, hunting, transportation and recreation. The development of irrigated agriculture in Amudarya and the flow of water from the Syrdarya has decreased dramatically. As a result, the Aral Sea has become an unusable area due to its high salinity level. The dried bottom area is 4.2 million hectares and has become a source of dust and salt distribution to the surrounding areas.
The amount of salt in the water is up to 112 g. Currently, the sea level is dropping by 80-110 cm. The region of the Aral Sea has become a large dust area. The problem of the island has a serious impact on the health of the people living in the area
In the last 10 years, the death rate has doubled. The amount of salts in the urine of 90% of children has increased. Anemia has occurred in 80% of women. From this area, 80 to 100 tons of dust rises into the atmosphere every year and reaches the Pamir, Tianshan, Greenland, and even the Arctic glaciers.
During the last 4 years, 1.5 million hectares of the dry part of the seabed has been turned into forest and shrubland. The addition of another 700,000 hectares shows the magnitude of the work being carried out in our country. In 2017, the United Nations established a multilateral partnership trust fund for human security. provides practical assistance to the population of the State Program for the Development of Aral Sea Regions in 2017-2021, with the relevant decisions of the Cabinet of Ministers on the creation of a “Green Belt” in the Aral Sea and Aral Sea Regions, neighboring Khorezm, Bukhara, and Navoi regions works are being carried out. The presidential decision to approve the concept of development of the forest system in our Republic until 2030 proves that these goals are strategic.
2. Regional (regional) problems are problems specific to certain regions caused by industrial sectors, enterprises and improper irrigation of land.
We will get acquainted with such problems – industrial waste of natural waters – problems in the agro-industrial complex.
Today, we are making progress in all fields in our country.
This achievement leads to the aggravation of the environmental situation along with the introduction of new technologies in industrial production. In recent years, along with the growth of industrial sectors, environmental pollution is also increasing. Due to the activities of industrial sectors, harmful dust and gaseous compounds are released into the environment in large quantities, and it is allowed to have a direct negative impact on the environment.
3. Local (native) environmental problems are problems specific to certain regions, even if they arise as a result of harmful emissions from all sectors of the national economy, industry and transport. The gases released from them damage the atmosphere and have a negative effect on human health. 70%-80% of air pollution comes from motor vehicles.
Garbage. The epidemiological and hygienic importance of keeping cities and villages clean is very great. The cleanliness and beauty of residential areas, the flow of water from irrigation canals, the presence of trees and green areas help prevent infectious diseases. leads to accumulation. In order to keep people’s residences clean, it is necessary to dispose of garbage in the garbage chute on time. Garbage and garbage not only cause various infectious and worm diseases, but also cause indigestion and nausea in people. Taking into account the sanitary and epidemiological danger of garbage when loading them into garbage trucks.
When unloading, the participation of people should be reduced as much as possible. According to a special schedule, garbage trucks take away the collected garbage. Liquid waste is removed using sewage pipes. Thus, the issue of waste is one of the important problems in ecology, and if it is collected and processed or sorted according to hygienic requirements, it has gained great importance for the environment and human health.
CONCLUSION Humanity takes all the things necessary for living and living from mother nature. Over the years, as a result of the increase in human needs, nature has been ruthlessly used, neglecting its precious benefits, using animals, plants and all natural resources as much as it wants (inappropriately) for its own selfish purposes.
We are in the vortex of huge environmental problems due to the great changes in the biosphere. In order to avoid the above problems and to improve the ecology, we must form an ecological culture in the population, form a deeper and more comprehensive understanding of caring for the environment and preserving it. teaching and, if necessary, learning is important.
