Air pollution significantly impacts visibility, primarily through the formation of atmospheric haze. Particulate matter (PM), such as soot, dust, and aerosols, suspend in the air and scatter and absorb light, thereby reducing the clarity and distance over which objects can be seen clearly. The presence of pollutants like nitrogen oxides (NOx) and sulfur dioxide (SO2) leads to the formation of secondary aerosols, which contribute markedly to haze formation (Seinfeld & Pandis, 2016). This reduction in visibility can considerably affect transportation safety, especially for aviation, maritime navigation, and road traffic. Furthermore, atmospheric haze diminishes scenic beauty, impacting tourism and outdoor recreational activities, and can also contribute to health issues when inhaled by humans, such as respiratory and cardiovascular diseases (EPA, 2019). The detrimental effects of haze extend beyond visual impairment to environmental degradation, as pollutants deposited via wet and dry deposition can harm ecosystems and aquatic systems. Therefore, controlling particulate emissions and gaseous precursors is necessary to mitigate haze formation and improve air quality (Seinfeld & Pandis, 2016).

Acid rain results from sulfur dioxide (SO2) and nitrogen oxides (NOx) emissions, which react with water vapor in the atmosphere to produce sulfuric and nitric acids. These acids fall to the ground with precipitation and cause detrimental effects on both vegetation and wildlife. In plants, acid rain can leach essential nutrients from the soil, such as calcium and magnesium, impairing root development and reducing plant productivity (Likens et al., 2017). It also damages the leaves and bark of trees, making them more susceptible to pests and diseases. For wildlife, acidified water bodies alter the pH, harming aquatic organisms like fish and invertebrates, and disrupting reproductive cycles and growth (Driscoll et al., 2001). Despite significant efforts in reducing emissions through policies like the Clean Air Act Amendments, progress in fully resolving acid rain issues remains incomplete. While emissions have decreased, many regions still experience episodes of acid deposition due to ongoing industrial activity and transportation emissions (Likens et al., 2017). Continued enforcement of emission controls and adoption of cleaner technologies are critical to progress in addressing acid rain comprehensively.

Air pollution has profound impacts on coral reefs and the marine food chain. Pollutants such as nutrients, heavy metals, and plastics entering marine environments lead to eutrophication, harmful algal blooms, and physical damage to coral structures (Fabricius et al., 2019). Elevated nutrient levels promote excessive algal growth, which can block sunlight necessary for photosynthesis by symbiotic algae residing within corals, leading to coral bleaching and mortality. Additionally, pollutants like heavy metals accumulate in marine organisms, disrupting reproductive and immune systems, which can cascade through the food chain (Carroll et al., 2020). Climate change exacerbates these issues through ocean warming and acidification, further stressing coral ecosystems. If current trends continue, many experts predict that most coral reefs may be significantly degraded or lost by the end of the century. However, efforts to reduce local pollution and global greenhouse gas emissions could help preserve some reef areas. Nonetheless, preventing widespread extinction hinges on rapid and sustained ecological policy responses to mitigate multiple stressors affecting coral reefs (Fabricius et al., 2019).
