Sometimes when I pass some places in my town, I often see piles of trash on the sides of the street or even on the banks of river.I think the view is annoying because it makes our surroundings look ugly and very dirty. In my opinion, it is also very dangerous. Piles of trash bring bacteria with them. Besides, If we walk near the pile of trash, we can smell fool odors coming from it.
    
            However, many people live around this mountain- like heap of trash. Many children play nearby. Also, a lot of women wash clothes and fruits and vegetables in the river which is contaminated by trash. This is terrible. I think they don’t realize the danger, because they don’t have knowledge about healthy living.
             In my opinion, the government must make a regulation that prohibits people to build houses near the trash disposal (dump site). Also, there should be special officers, like police officers, who watch and catch people who throw trash on the ground or into the rivers. Moreover, if a big fine doesn’t make people stop dropping litter carelessly, the government should put them in jail as punishment.
            Finally, I think the efforts to keep our environment clean and tidy need hard work from both the citizens and government.
