A class outing It is an unforgettable experience that my high school teacher asked her students to clean the beach. I was been deeply affect by she said"we are part of the world, while our mother earth has been suffering, we have to stand up for her and take responsibility." When we arrived southern beach of Taoyuan only to see the uncountable garbage spreading out over the beach, even some were floating on the sea. In a huge shock, I realized what a devastation our human had brought to mother earth. Thus, even though the sun was scorching, none of us complained. Finally, taking an afternoon we finish our job. I arise a sense of achievement as seeing the beach return to clean again. After then, I made up my mind to cut down my daily waste, there is no planet B.
