Air pollution is one of the most serious environmental challenges facing humanity in the 21st century. The main sources of pollution are industrial emissions, vehicle exhaust fumes, and the burning of fossil fuels in power plants and residential heating. These activities release harmful substances into the air: sulfur dioxide, nitrogen oxides, carbon monoxide, fine particulate matter, and heavy metals. The situation is especially critical in megacities, where dense traffic and industrial activity lead to chronically polluted air.

Breathing polluted air has a daily negative impact on human health. The most vulnerable groups are children, the elderly, and those suffering from respiratory or cardiovascular diseases. Studies by the World Health Organization confirm a direct correlation between air pollution and the increase in asthma, bronchitis, strokes, and even cancer cases. Moreover, polluted air lowers the quality of life, disrupts ecosystems, and worsens the global climate situation.

One of the major consequences of air pollution is the intensification of the greenhouse effect and global warming. Carbon dioxide (CO₂), methane (CH₄), and other gases accumulate in the atmosphere and trap heat. This leads to the melting of glaciers, rising sea levels, increased frequency of extreme weather events, and disruption of natural cycles. These changes not only threaten ecosystems but also the stability of economies, especially in vulnerable regions.

To effectively tackle this issue, cooperation at both international and local levels is essential. Countries must implement strict emission standards and invest in clean technologies. Urban planning should prioritize green zones, limit vehicle access in congested areas, and encourage cycling and walking. Schools and universities should integrate environmental education into their curricula, empowering future generations to act responsibly. Only through united global effort can we hope to preserve clean air for ourselves and future generations.
