Environmental problems: a comprehensive analysis of the interaction of man and nature

Global warming and climate change: threat to the planet

Global warming, caused by an increase in the concentration of greenhouse gases in the atmosphere, is one of the most serious environmental problems facing humanity. This process, primarily due to human activity, leads to a change in climatic models, an increase in sea level, the rapid of extreme weather phenomena and, as a result, to significant socio-economic and environmental consequences.

Causes of global warming:

• Burning of fossil fuel: Coal, oil and natural gas used for energy production, when combined, is released into the atmosphere carbon dioxide (CO2), methane (CH4) and other greenhouse gases. CO2 is the most significant greenhouse gas, the contribution of which is about 60%to global warming.
• Forest cutting down: Forests play an important role in the regulation of the climate, absorbing CO2 from the atmosphere through photosynthesis. Forest cutting down not only reduces the planet’s ability to absorb CO2, but also leads to the release of carbon accumulated in trees and soil.
• Agriculture: Agricultural activity, especially livestock and rice growing, is a significant source of greenhouse gases, such as methane and nitrogen oxide (N2O). The use of nitrogen fertilizers also contributes to n2O emissions.
• Industry: Industrial processes, such as the production of cement, steel and chemicals, are also sources of greenhouse gases.
• Transport: Cars, aircraft and other modes of transport working on fossil fuel are significant sources of CO2 emissions.

The consequences of global warming:

• Temperature increase: The average global temperature has already risen by about 1 degree of Celsius compared to the pre -industrial level. A further increase in temperature can lead to catastrophic consequences, including increased extreme weather phenomena, such as droughts, floods, hurricanes and forest fires.
• Improving sea level: The melting of glaciers and thermal expansion of ocean water lead to an increase in sea level. This poses a threat to coastal cities and ecosystems, such as mangrove thickets and coral reefs.
• Change in climatic zones: Climate change leads to a displacement of climatic zones, which affects the distribution of vegetation and animals. Some species will not be able to adapt to changing conditions and die out.
• Deterioration of human health: Global warming can lead to an increase in the spread of infectious diseases, exacerbation of respiratory diseases and heat strokes.
• Food safety: Climate change can negatively affect the crop yield of agricultural crops, which will lead to food crises and an increase in food prices.
• Lack of water: Climate change can lead to a decrease in the amount of available fresh water in some regions, which will lead to conflicts due to water resources.

Measures to combat global warming:

• Transition to renewable energy sources: It is necessary to reduce dependence on fossil fuel and switch to renewable energy sources, such as solar, wind, hydro- and geothermal energy.
• Improving energy efficiency: It is necessary to increase the energy efficiency of buildings, transport and industry in order to reduce energy consumption.
• Preservation and restoration of forests: It is necessary to stop cutting forests and restore lost forests.
• Sustainable agriculture: It is necessary to introduce stable agricultural methods that reduce greenhouse gas emissions and increase the resistance to climate change.
• Carbon pricing: It is necessary to introduce carbon pricing mechanisms, such as taxes on carbon emissions or quotas trading systems for emissions in order to stimulate the reduction of greenhouse gas emissions.
• International cooperation: International cooperation is necessary for the development and implementation of effective strategies for combating global warming.

Air pollution: threat to human health and environment

Air pollution caused by emissions of harmful substances into the atmosphere is a serious environmental problem that has a negative impact on human health, ecosystems and climate. Sources of air pollution can be both anthropogenic (related to human activity) and natural factors.

Air pollution sources:

• Transport: Cars, trucks, aircraft and other modes of transport operating on fossil fuel are significant sources of emissions of pollutants, such as nitrogen oxides, solid particles (PM), carbon monoxide (CO) and volatile organic compounds (VOC).

They can be both primary (thrown directly into the atmosphere) and secondary (formed as a result of chemical reactions in the atmosphere). PM2.5 (particles with a diameter of less than 2.5 micrometers) and PM10 (particles with a diameter of less than 10 micrometers) are considered the most dangerous to human health, since they can penetrate deep into the lungs and cause respiratory and cardiovascular diseases.
• Ozon (O3): Ozone is a secondary pollutant formed as a result of chemical reactions between NOX and VOC in the presence of sunlight. High concentrations of ozone in the surface layer of the atmosphere can cause respiratory diseases, irritation of the eyes and a decrease in agricultural crop yields.
• Nitrogen oxides (Nox): Nitrogen oxides are formed during the burning of fossil fuel. They are the predecessors of ozone and acid rains, and can also cause respiratory diseases.
