A 400-word essay on protecting the environment

Protecting the environment starts with me. The sky, because the exhaust gases from factories and cars have turned from blue to gray-white; the forest, because instead of protecting it, people uprooted the trees. The lush trees disappeared and were replaced by desolation. Dad said that the pollution in our city is very serious. He also told me that the main cause of air pollution is the black smoke from chimneys, insufficient greening, and strong winds blowing up dust all over the sky. After hearing these words, I thought to myself: People in those factories would destroy the earth that gave birth to us for the sake of convenience! Once my brother and I saw this environmental slogan on TV: "Protecting the environment starts with me." Everyone can say this, but why can’t people do it? Last summer, our family went to Nanjing for a trip. When we went to Sun Yat-sen Mausoleum, we saw a cleaner throwing the plastic bag containing steamed buns on the ground. I said: "She is still a cleaner, why did she just give it to her like this?" Is Dadi infected with 'psoriasis'?" On our way home, I was sweating profusely, so I went to the canteen and bought a popsicle. After eating, I threw the remaining stick on the road. At this time, my move was seen by another cleaner. She picked up the wooden stick, raised her head and said to me kindly: "Children, we have to protect the cleanliness of the city. If you do this, you will pollute the environment!" At this time, my face turned red... Sitting on the long-distance bus, the scene just now could not help but reappear in front of my eyes. I thought silently in my heart: We are also cleaners, but what is the difference between good, evil, beauty and ugliness? Is it that big? Another Sunday, I went to my brother's house to play. When he saw me, he immediately took out a lot of snacks for me to eat. After eating, he opened the window and threw the bags from the second floor "coolly". Just now I, who was still full of joy, suddenly straightened my face and said seriously to my brother: "Have you forgotten the environmental protection slogan you saw on TV last time? Didn't you also say at that time, 'Let us start from ourselves and protect it together. Environment! 'Could it be that you said it out of "good intentions"? "My words made my brother extremely ashamed, and he promised me that he would never throw paper scraps again. He took my hand and went downstairs to pick up garbage. After an hour of hard work, the "project" was finally "completed". Some people throw their garbage on the side of the road casually, or burn it, but have they ever thought that doing so will destroy the ozone layer and produce a "greenhouse effect"? We should start from ourselves, be a little environmental protection guardian, and care for nature. I hope that in the near future, the sky here will be bluer, the water will be clearer, and the earth will become a real "blue planet" .
