Last Tuesday, we had a class meeting to discuss where to go for our spring outing. We came up with a few choices, such as going boating, climbing a mountain, and going to an amusement park. Finally we decided to go mountain clibming. The next day, we set off earl in the morning. While climbing the mountain, we enjoyed the warm sunshine and the beautiful view. However, when we reached the top, we were shocked to see litter here and there, such as bottles and banana peels. 
 
Then we started to pick up the litter. Afterwards, we put the rubbish into the recycling bin and none recycling bin respectively. We were tired but happy. We think everyone has the duty to protect out environment.
