As we all know that the Pyramid is well-known all over the world,the Pyramid is not only one of the world wonders,but also the crystal of wisdom,therefore,to protect the Pyramids is of great meaning.
In the past few years,as more and more visitors pay a visit to the Pyramid and the globall climate turns worse and worse,the Pyramid has been serious damaged.
In fact,the greatest harm to the Pyramid is caused by nature.In order to protect it,we should reduce the emission of the acidic gas,aimed at drop the incidence of the acid rain.In addition,when we visit the Pyramid,we should try our best no touch the objects in it,and it will be better not to stay in it for too long.
