Looking after our sites of great value

In the middle of last month, UNESCO warned that it would put the Lascaus caves in France on its "List of World Heritage in Danger" if the French government did not take effective measures by next February in its treatment of gray and black fungi which is destroying the caves' paintings.
Known as the "Sistine Chapel of prehistory", the paintings are under threat, ironically, because they are subject to protection. To control the temperature and humidity in the caves, the French government installed an air control system. Soon after that, the drawings began to be contaminated by mold caused by the fungi.
After reading this news, I cannot help wondering about the conservation of world heritages in our own country. Today, there are 37 Chinese cultural and natural heritages on the UNESCO list.
