my homtown was very beautiful and peaceful in the past, there were many trees ,surrounding our hometown,the rivers had plently of fish ,which played water in river, although people lived a small and simple house ,but they were contented and happniess,because they are hard-working by their effort to make their life better,but nowadays, many of this had changed , there are many buildings and factories appearred, many of cars on street ,with the developing of the industry, the environment is becoming more and more worse, the forest are destroied, because of the environment pollution ,the fish has gone in river ,so what is most important thingto do is reduce the pollution ,we should apeal people to protecting the environment.
