Dear Jack,

　　Thank you for your letter asking about our discussion on low carbon lifestyle. Here is something about it.

　　We should do something to protect our environment. At first，we should save water and electricity.We shouldn"t waste our water.So we use water again and again.If we leave our room,we should turn off lights and computer timely.Second, we shouldn"t throw the trash everwhere.

　　And we should separate the garbage processing.Next,we should use tissue less ,and use it again and again.Finally,if we go out ,we can go on foot instead taking cars,we also can go out by bike and bus.

　　Best wishes,

　　Li Bing
