Support you. Use recycled bags can protect environment to against global warming. Some cell phones such as Apple 3G iphone have excellent musical function but the users should wear earphone to enjoy. In public libraries of the United States, lots of people hear music by earphones but the whole liabrary still can keep quite. If someone make noise, others must voice out immediately. So everyone has responsibility to actively protect the environment what we are living.

俺一年四季随身携带购物袋，公车上的那些手机噪音十有八九是山寨的，喇叭大，声音大符合他们的心理：）

如果每个中国人都像你一样的关心环保，这么有公德心，那比欧美国家的人素质都要高了。别说大环境的保护了，在他们眼里除了自己家都是垃圾场，楼道可以随便祸害，垃圾可以直接从楼上抛下，你指望这样的人现在就达到那种素质，太难了！现在做好自己，只要自己心安就可以，生活在中国，很多事情就得见怪不怪。公众场合大声放手机里的音乐确实烦人，很有同感，这是自我为中心的体现。

哈，跟我的感受一样呀，不过那样一类多数是小毛青年，不要和他们一般见识呀。
