Air pollution significantly impacts the environment through various mechanisms. It can lead to acid rain, formed when sulfur dioxide and nitrogen oxides combine with atmospheric water vapor. This acidic precipitation damages water, forest, and soil resources, harming aquatic life and weakening trees. Acid rain also corrodes buildings and monuments.
Furthermore, air pollutants can transcend local boundaries, affecting global climate and weather patterns. The depletion of the stratospheric ozone layer by pollutants like chlorofluorocarbons (CFCs) allows more harmful ultraviolet radiation to reach the Earth’s surface. Another major consequence of air pollution is climate change, particularly global warming, driven by increased greenhouse gas emissions like carbon dioxide from fossil fuel combustion. This warming can lead to rising sea levels and altered precipitation patterns.
