Acid rain eats away at stone, metal, paint -- almost
any material exposed to the weather for a long period of time.
Human-made materials gradually deteriorate even when exposed
to unpolluted rain, but acid rain accelerates the process. Acid
rain can cause marble statues carved long ago to lose their features.
Acid rain has the same effect on buildings and monuments. Repairing
acid rain damage to houses, buildings, and monuments can cost
billions of dollars. Ancient monuments and buildings, such as
the Parthenon in Greece, can never be replaced.

demonstrate this effect of acid rain.
