On Sunday, the sun was shining brightly. My friends and I made an appointment to visit Nanzhao Mountain Park. I was so happy that I didn't step out of the building when I got downstairs. A "mine" blocked my way. I screamed and almost stepped on the dog's feces. I thought: "Pipi" at Aunt Zhang's house on the second floor must be playing a prank. I walked around and just wanted to go. Then I thought again: Grandma Zhang on the third floor would go downstairs to bask in the sun every day. Her eyes were bad. What if she stepped on them? So I ran home quickly, got a broom and a pinch, and cleaned up the dog's feces. Pippi ran over and barked twice, as if to say, "Why did you destroy my masterpiece?"

When we arrived at Nanzhaoshan Park, our friends were worried and asked why I was late. I smiled and said, "I went to mine." We couldn't wait to run to the river, which was our old "paradise". But now we are shocked that the original clear river has disappeared and replaced by the stinking garbage river. Passers by cover their mouths and noses, and we left the former "paradise". When I came to Nanshan, I just wanted to play hide and seek, but I found a lot of white pollution. At this moment, it is a world of garbage. Several of our little friends discussed and decided not to play. We went down the mountain to buy shopping bags and started our "new plan" to be a little environmental guard, ready to pick up garbage. We ran all over the mountain and sweated so hard that we put bags of garbage into the garbage can. It's getting dark, we must go home, and our environmental protection action will come to an end. Although the travel plan failed, we were still very happy because we did a good thing and became a "little environmental protection guard".

Back on campus, we will form an "environmental protection team" to recruit more "environmental protection guards."
