What is one environmental effect of acid rain?

Acid rain is a significant environmental issue that results from the emission of sulfur dioxide and nitrogen oxides into the atmosphere, which then combine with water vapor to form acidic compounds. This environmental phenomenon can have detrimental effects on various ecosystems, particularly aquatic systems.

One of the most severe impacts of acid rain is its ability to lower the pH of water bodies such as lakes and streams. Many aquatic organisms, including fish and amphibians, have a narrow range of pH tolerance. When the pH falls due to acid rain, it can lead to negative consequences such as increased mortality rates, impaired reproduction, and decreased biodiversity. Moreover, acid rain can leach toxic metals such as aluminum from soils into waterways, further harming aquatic life. The combined effects significantly disrupt food chains and the health of these ecosystems, making the correct choice reflect a clear understanding of the serious implications of acid rain on aquatic environments.

In contrast, promoting plant growth and enhancing soil fertility are incorrect perceptions of acid rain's effects. While certain forms of rain provide necessary nutrients, acid rain tends to harm plant life by damaging leaves and leaching essential minerals from the soil. The notion that acid rain removes harmful bacteria in water does not accurately represent its environmental impact, as the overall effect is detrimental
