Nowadays, there are fewer people protecting the environment, and cities are getting dirtier and dirtier. I want to be a little guardian of environmental protection and take care of our home. On the morning of July 2 1, my grandfather and I were picking up garbage and weeding in the harbour garden. First, we pick up the garbage with a shovel and other tools. When we see the peel scraps on the ground, we sweep them into the dustpan with a broom and then pour them into the trash can. We went to weed again, picked up scissors to cut off the dead leaves on the tree, and only heard a click, and the weeds on the ground disappeared. We found a small tree bent by the wind. It is bent in the hot sun and looks very tired. I went home with a stick and a rope. I hold the little tree. Grandpa inserted the stick into the soil next to the small tree, and then tied the small tree and the stick together with a rope for several times. In this way, the little tree stood upright, like a soldier on guard. Finally, we drew a handwritten environmental report, wrote a slogan on it and posted it on the bulletin board. I think that as long as someone sees this painting, they will act and spread all over the city, and the city will become very clean and beautiful. I believe that as long as you protect the environment, you will also become a qualified environmental defender.
