Ruining the Ruins
Acid rain (酸雨)is now a familiar problem in the industrialized countries in Europe. Harmful gases are produced by power stations and cars. They dissolve in rainwater and this makes acid rain, which damages trees, rivers and streams.
Acid rain is also capable of dissolving some rocks. And buildings made of soft rock, such as limestone (石灰石), are particularly badly affected. The acid rain attacks the rock, and so carvings and statues are eroded (受腐蝕) more quickly.
__________(46) According to a report in the New Scientist, acid rain is being blamed for the rapid decay of ancient ruins in Mexico. The old limestone buildings in places like Chichen Itza, Tulum and Palenque are wearing away very quickly indeed. These sites are the remains of the buildings built by the Mayas between 250 BC and AD900, and the spectacular ruins of Mayan civilization are visited by thousands of tourists every year.
But those ruins are in danger of being seriously damaged by pollution. At many sites the stone has been covered with a layer of black substance. ________________(47).
