            <Attribute name="description">Acid rain, caused by pollution from burning fossil fuels, has harmful effects on the environment and human health. It forms when sulfur and nitrogen oxides interact with UV radiation and water molecules, creating corrosive sulfuric and nitric acid vapors. Acid rain damages buildings, contaminates water, acidifies soils, and harms forests. Despite reductions in emissions, it remains a global issue.</Attribute>
