Abstract
Air pollution has become one of the most pressing environmental and public health concerns of the 21st century. Exposure to polluted air contributes to millions of premature deaths annually, affecting the respiratory, cardiovascular, and nervous systems. This paper explores the main sources of air pollution, its physiological impacts on human health, and the global strategies for mitigation. Findings indicate that prolonged exposure to pollutants such as particulate matter (PM2.5), nitrogen oxides (NOx), sulfur dioxide (SO₂), and ozone (O₃) increases the risk of chronic respiratory diseases, heart conditions, and cancer. Addressing air pollution through policy enforcement, technological innovation, and public awareness is essential to improving global health outcomes.References
