these days, we discuss about how to protect the environment and built the harmonious society. many students give us their ways and i think theses ways will be helpful.

　　in my opinion, how to dispose of rubbish is a very important thing. First, rubbish is a great pollution in city, and how to deal with them has been a big problem .there are many ways such as classify ,collect, sometimes we can buy the rubbish and don’ t forget to deal with the polluted water .also, the ways of provide against the pollution is very important .we should make laws to stop people from throwing away the rubbish and make city more beautiful.

　　anyway ,the society is ours, the world is ours. all of us should make contributions to protect the environment, protect everything around us. i believe, if everyone an help. we can make a harmonious society in a short time.
