I used to feel disgusted when I saw people recycling on the roadsides. However, I have changed my opinion after interviewing with Mr. Han, a volunteer. The phrase “we have only one earth” impresses me.  It is backbreaking to recycle that you can tire easily and you have to stand the foul smell. However, Mr. Han always concentrates on his work, in spite of the difficulties. I think I will try to help the next time I see someone recycling.（Li）
