Eroded limestone building. Close-up of carved architectural features on a cathedral,showing the effects of acid rain on limestone. Normal rain is slightly acidic,mainly carbonic acid,and this slowly erodes the limestone. In industrial societies,however,sulphuric and nitric acids from factory and traffic pollution increase the rate and amount of erosion. Photographed in Palma de Mallorca,Mallorca,Spain | |
