The fourth level of environmental protection composition 1 Due to the increasingly developed technology and social development, people have more and more cars. We all know that most cars are powered by burning fuel, and burning a lot of fuel will emit a lot of exhaust gas. Waste gas contains a lot of toxic substances, which will destroy the ozone layer in the atmosphere, seriously damage the ecological environment, produce a "greenhouse effect" and affect our life and health. Some waste gases contain carcinogens, which can also make us suffer from cancer and even lead to death.
Therefore, people need a new type of car that will not pose a threat to us-"eco-car", which is a future multi-mode control car: 1, using solar cells. On sunny days, solar panels covered with many flat mirrors focus sunlight and generate powerful heat energy, which is converted into powerful electric energy by silicon solar cells. 2. In rainy days, the rain constantly impacts the surface of the car, and the car shell absorbs the impact of the rain, and then converts it into kinetic energy through a special device, which is transmitted to the wheels all the way to make the car run. There are many such technologies.
I hope that one day, my dream eco-car technology will mature rapidly, replace the current fuel car and become the mainstream of the future car, which will not only provide convenience for people's travel, but also give consideration to environmental protection.
Environmental protection is very important to people, because the air and water resources on the earth are already very poor. If human beings continue to pollute the environment, there will be no pure water and beautiful air on the earth! So I want to set up an environmental protection festival to let everyone experience the importance of environmental protection to all living things.
Some people may laugh at my aunt and grandpa who helped us clean the road, but that's not right, because without help, our road will not be so neat, so we can't laugh at them.
During the environmental protection festival, people can exchange used batteries for a new light bulb. The significance of this is to prevent people from throwing batteries around. People can volunteer and experience the hard work of sweeping the road. The significance of this is to let people know that they can't litter. People can make some small slogans, such as: The grass is green, please don't trample on it! Protecting the environment is everyone's responsibility! And so on, to declare that people protect the environment. People can also buy some seedlings to plant, not only to watch them grow tall and thick, but also to purify the air.
Speaking of trees, they are really useful. They can shield us from the sun, they can shield us from storms, they can absorb carbon dioxide and highlight fresh air. ...
On the environmental protection festival, people can protect flowers and plants and don't litter. I really hope that environmental protection and energy conservation will be established soon.
Dear students, grade four environmental protection composition 3:
The earth is our home for human survival, but now our home is deteriorating. With the increase of factories, a lot of waste gas is discharged. With people littering, especially in harmful waste, the sky is no longer as blue as before, the earth is no longer as green as before, and the rivers are no longer as clear as before, which has affected our life and health. Can you still live in such a home at this rate? In order to protect our lives and health, from now on, we should vigorously advocate the wind of environmental protection, keep pollution away from us and let green accompany us. In this regard, I send the following initiatives to my classmates:
1, organize the publicity of urban environmental protection knowledge.
2. Organize students to group to collect garbage in public places in the city on weekly rest days.
3. Hold the talent contest "Good habit of saving water and electricity without wasting resources".
4. Make beautiful and practical handicrafts with recycled items such as waste paper shells, plastics and cans.
5, the city's primary school students above grade three, insist on planting 2 trees every year.
Students, protecting the environment is everyone's responsibility. Let's join hands, for the blue sky, green land and clear water of our home, and for the beautiful living environment, I hope the students will give their love and strength!

Fourth grade environmental protection composition 4 "Protecting the environment is everyone's responsibility!" Yes, protecting the environment is not only everyone's unshirkable responsibility, but also the embodiment of a person's noble character. You bent down to pick up a piece of paper and a plastic bag on the ground ... isn't it protecting the environment? Think about it, if each of us didn't litter casually, we would pick up all the rubbish like plastic bags and throw it into the dustbin. How beautiful and lovely the world will be! Although it is easy, did you find a piece of paper and a plastic bag when you were playing in the street? So hard that you think it's none of your business? Garbage pollutes the fresh air. Is it healthy for people to breathe this air? At least you will stop littering on the ground forever! Some people just eat melon seeds and throw their skins on the ground for their own convenience, some people spit everywhere, and some people ... this is not only bad for the health of others, but also bad for their own health!
We can't stop people from cutting down a few forest resources indiscriminately; We can't stop people from killing rare animals indiscriminately; We can't stop the "three wastes" discharged by factories. The garbage produced by urban life pollutes rivers, lakes and seas and our blue sky. We can't stop the overwhelming white garbage from polluting the environment. ...
We can't stop too many things from damaging the environment, but we can also do a lot to protect the environment. We can start with small things and do what we can.
Friend, don't you want to see the blue sky? Don't you want to see the clear river? Don't you want to breathe fresh air? Don't you want to have a healthy body?
Friends, let's create together and have a beautiful home together!
Environmental protection is our eternal theme, always the first in every country. Of course, if we don't act now, we will become extinct like dinosaurs in the near future.
Therefore, many celebrities have said famous sayings about environmental protection to warn us. For example, only obeying nature can defeat nature-Darwin; Nature is a kind mother and a cruel butcher-Hugo; People often regard the surrounding environment as a free commodity, and spoil it at will, but don't know how to cherish it-Gan Haman; The earth gives all people the essence of matter, but in the end, what it gets from people is the garbage of these matters-Whitman. ...
Don't we get anything from these famous sayings? Then let's take a look at our "masterpiece": Tangshan earthquake; Severe snowstorm occurred in Xinjiang; The worst drought in a century in southwest provinces and cities; A large-scale sandstorm broke out in the north; Wenchuan earthquake with M = 5. 12 in Sichuan. ...
Isn't the lesson of blood enough to make us humans disappear from the earth like dinosaurs? Don't we all want to see the magnificent mountains and rivers of our motherland? We don't want to see stumps, piles of garbage, pools of sewage and a personal heart!
On TV, the topic of environmental protection is often mentioned. As a contemporary primary school student, I must talk about environmental protection, protect the environment and care for our home in my life.
In life, I try not to use disposable chopsticks because it is too wasteful. When I go out, my parents take me to school by electric car or bike, so that I can exercise. Sometimes I will take the initiative to ask my parents not to pick me up and go home with a few classmates, which is not only low-carbon and environmentally friendly, but also can exercise. After a long time, I have grown a lot!
Secretly tell you, I am still a small model for practicing environmental protection! Once, grandpa saw some rubbish outside our hutong, so he set them on fire and prepared to burn them. I happened to see it, so I quickly stopped my grandfather and told him that burning garbage not only destroyed the environment, but also produced exhaust gas that was not good for my health. Grandpa listened to my words, took the initiative to put out the flame, transported the garbage to the garbage collection station, and never burned the garbage again.
During the holiday, my mother took me out to play. I was very happy when I saw the splashing fountains, rockeries, running water and beautiful flowers in full bloom in the square. I sat on the green lawn, breathing fresh air. I think life is so beautiful. The clear river rippled with the wind, and the fisherman sat quietly under the pole. From time to time, fish rise with the pole. Looking up at the blue sky and white clouds, birds fly briskly, and the picture of people living in harmony with nature and animals is so harmonious.
Shade patches, cool breeze blowing gently, in the beautiful urban environment, how happy our life is!
