Students should first understand by themselves that taking care of our historical monuments is the duty of each and every citizen.They can convince the person who scribbles something on the walls of historical monuments.They can convince them by saying how historical monuments have helped  our country in its economic conditions as in the way of tourism.Its because of the beauty of our historical monuments that there is a huge tourist flow in our country.If we make our monuments ugly then they will loose their interest in seeing our monuments causing a very serious economic problem to our country.
