A combination of rain,salt,air pollution,sun,sand and wind may destroy the huge statue in the outer areas of Cairo. This statue of the sun god has the body of a lion and the face of a human being. It is five thousand years old and it is badly damaged.
The problems are very serious. First,the underground passages around the statue are blocked. Too much rain had run into the stone statue. As a result, small pierces of salt left on the stone have damaged it.
Secondly,air pollution from the traffic in Cairo is also destroying the ancient statue. The dirty air is making the stone crumble and decay even faster.
Thirdly,extremes of temperatures are damaging the satue. For example,alhough the air is very cold at night during the day the stone of the statue becomes very hot under the strong sun. Other natural forces such ad sandstorms also attack the statue.
Finally,the tourists who visit the statue every day also cause a lot of damage.
