Acids reacting with calcium carbonate will release carbon dioxide. Acid precipitation can cause trees to die. Why is this of concern?

• Lakes and streams become acidic and fish die.

• Both cause an increase in CO₂ which contributes to climate change.

• Iron and steel production, as well as automobiles emit gases that contribute to acid precipitation.

• Stone surfaces, bridges and roads are corroding and are expensive to replace.
