In recent years many of the world leading ancient wonders preservators have published that the modern environment has a large impact on these historic buildings and sites. One of the latest discoveries in this field states that ultraviolet radiation(UVR) has a large impact on the material from which these buildings are built. The material itself may be imune to such things at first, but being exsposed to it for such a long time surely takes it toll, not to mention that time itself slowly degrades all materials on Earth. In these statments the leading researchers say that UVR seems to influence the bonds between atoms and molecules, and with this making the material(in this case rock) much less durable than usually. Such cases were found in Egypt(Pyramids), Rome(Coliseum)and almost all other locations where there are hot and dry summers(deserts, mediterainian climate).
