To improve comfort and cleanliness at our school, a number of dust bins should be increased. When we look at classrooms, school corridors and school yard, there are paper mineral water cups, straws, and napkins here and there. The condition of uncleanliness and discomfort really hinders learning and teaching environment. Litters thrown carelessly cause disease, especially empty plastic cup or glasses. They can be filled out with water coming from the rain. This can be placed for dengue mosquitoes to spread out. Besides, these rubbish can deteriorate the scene. Well painted wall and green school yard do not mean anything litters are scattered everywhere.

    Anyway I notice that most of the students in our school have responsibilities for the school environment. They put their litters on the proper places. But some are not diligent enough to find the dust bins. The numbers of dust binds in our schools are not enough. Ore dust bins should be put beside each of steps, outside of the classrooms, and some more also the corridors. Probably one dust bin should be in every ten meters. So when students want to throw away their litters, they can find the dust bins easily.

    When school is equipped with sufficient dust bins, we do not have problems of freak and discomfort any more. Our school will be very clean and become a nice place to study.
