The immense amounts of sulphur dioxide emitted into the air causes high levels of acid in the atmosphere. When this sulphuric acid is absorbed into moisture in the air, poignant rainfalls can be damaging to the external environment. ... The sulphur dioxide, which diffuses into the air, mixes with moisture causing the pH levels to drop from the normal level. ... An inordinate amount of sulphur dioxide is let into the air, more than can be neutralized by nutrients in the air. ... The acid rain corrodes the thin, waxy layer, which coats and protects the leaves letting the acid suffocate the leave...
