Pollution affects non-biological systems in profound and far-reaching ways, altering the physical, chemical, and functional balance of air, water, soil, and climatic processes that support life and human activities. These systems, though non-living, form the foundation of ecological stability and human survival, and pollution disrupts their natural properties and cycles. Air pollution significantly alters the composition and quality of the atmosphere. Emissions of particulate matter, sulfur dioxide, nitrogen oxides, carbon monoxide, and volatile organic compounds change atmospheric chemistry, leading to phenomena such as smog, acid rain, and ozone layer depletion. Acidic pollutants react with moisture in the air and precipitate as acid rain, which corrodes buildings, monuments, and infrastructure, and alters the chemical composition
