Acid Rain - In the air carbon dioxide and water react to produce carbonic acid, making normal rain slightly acidic, a pH of 5.6. However the rain becomes more acidic due to air pollutants, such as sulfur oxides and nitrous oxides from vehicles and factories, which combine with water thus forming sulfuric acids and nitric acids. Acid rain has completely damaged the biodiversity of mountains and lakes, and even buildings and historic sculptures.
