Understanding Acid Rain

Acid rain, a result of pollution, is more acidic than normal rain due to sulfur and nitrogen oxides. These oxides form sulfuric and nitric acids when they interact with water and sunlight. Acid rain affects buildings, ecosystems, and human health but does not burn skin. Efforts like the EPA's Acid Rain Program have reduced emissions, yet global challenges remain. Transitioning to renewable energy can further mitigate acid rain.
