Acid rain is produced when rain falls through the pollution in the atmosphere and dissolves pollutants that make it the water in it acidic. This falls on the Earth and causes various environmental problems to trees and freshwater lakes.
It also causes problems in towns and cities when it falls on buildings made of stone and rock, particularly those that are constructed from limestone and sandstone. These react very readily with the acid water and the rock is actually dissolved and runs off the building.
This is bad in any building but it affects statues, removing the detail of their features and destroying their beauty. Damage by acid rain speeds up the usual erosion from wind, snow, ice and sunlight and statues that have been in place for hundreds of years are literally dissolving before our eyes. Restoration has been done in many buildings but it is expensive – the best solution is to prevent the pollution that causes acid rain in the first place.
