Speech by the host of the class meeting on environmental protection

Good afternoon, teachers and students! (Salute) The theme class meeting of striving to be a little environmental guardian begins now (sketch "On the Street") A: Do you know, classmates? The earth is our common home, and it is closely related to human beings. B: The earth has existed for billions of years. If these billions of years are counted as one day, then the time for human beings to survive on the earth will be less than one second! By the end of the 20th century, the population of the earth may reach more than 8 billion. People need food, water, living space and energy to drive vehicles. B: In this way, the food and living space of other animals and plants will be reduced, and there will be many problems in the ecological environment. Such as global warming, acid rain, ozone hole and so on. These are just a few questions. There is another big problem that cannot be ignored. Let's listen to Li Tianyi's explanation. We all need to know about our living environment and climate, as well as the animals and plants on our planet. A: Understand nature and be a small environmental guardian. In this way, our earth will be cleaner and more beautiful. Protecting our earth and home requires everyone's efforts. Please read "In the Park" (on the green doll). Green doll: Hey, little master, I'm here for your team meeting, too. Are you popular? Excuse me, who are you? Green doll: Hi, I'm a famous green doll! Today, I also brought you a new friend. Show the green food sign green doll: Do you know this friend? The sign consists of three parts, namely, the sun above, the leaves below and the flower buds in the middle, symbolizing the natural ecology; The color is green, symbolizing life, agriculture and environmental protection; The figure is a right circle, indicating protection. AA-level green food signs and fonts are green on a white background, while A-level green food signs and fonts are green on a white background. ) Green food logo refers to Chinese "green food", English "green food", green food logo graphics and their combination. It is registered on nine categories of food and extends to green food-related products such as fertilizers. B: Since everyone welcomes you so much, please invite Green Doll to host the team meeting with us! Green doll: (jumping up and clapping): Great! Great! A: Green doll, let's watch the sketch "Wash Your Hands": environmental protection, starting with small things around us ... B: environmental protection is not a new problem for us, and the government has already put forward clear governance goals. As an ordinary person in real life, although it is impossible for all of us to directly engage in environmental protection work, we can start from small things and start from me. A: Can we turn off the faucet in the bathroom when we see it dripping? Green doll: The battery is used up. Can it be collected separately instead of thrown away? B: Can you consciously not use ultra-thin plastic bags when shopping? ..... Although these little things are very inconspicuous, they show how much environmental awareness we have. Not only does garbage pollute the earth, but noise is also one of the pollution sources! ~ (Sketch at home) A: There is an old lady who takes a small cloth bag every time she goes shopping and a small steel spoon every time she goes to a restaurant. It looks ordinary, but it is really not easy for this old comrade to consciously insist on not using white plastic bags and disposable chopsticks for many years. This requires not only a firm belief in environmental protection but also good habits. A: There is no doubt that environmental awareness is closely related to people's education level. b； We should use practical actions to protect the environment, beautify the campus, beautify our hometown and make the sky bluer, the mountains greener and the water clearer in our hometown. Please come and read the ballads with them. A: Green doll, now let's test you and see how you are learning about environmental protection. Green doll: That's a good idea. I'll be the judge for you, and the winner will get the prize I gave you! Performers, please wait for the answer first. B: Four groups choose questions 1 to 4 respectively, and start to answer first. Let's see who raises their hands first. The first group is ready to start the green doll: OK, now the performer will start to answer first. Get ready to start A: Students, I believe you have learned a lot. Now, with the increasing improvement of human living standards and the rapid development of industry, people's destruction and pollution to the earth are becoming more and more serious. Next, let's look at some scenes in daily life! Green doll (at once): Oh, I have to go. Bye! (Under the green doll) Hehe: Today we learned and saw a lot of knowledge and examples about environmental protection. Protecting the environment is everyone's responsibility! This is the end of the theme class of striving to be a little guardian of environmental protection
