The fourth grade environmental protection composition 1 childhood is full of beautiful fantasies, and childhood is full of the pursuit of the future. My ideal is to become an environmental protection expert.
Air pollution does great harm to our health. To make people healthy, we must first have fresh air, and to keep the air fresh, we must find out the causes of air pollution. It is understood that the main causes of air pollution are automobile exhaust, factory exhaust and people spitting.
If I were an expert in environmental protection, I would produce a kind of pollution-free gasoline, which can automatically decompose exhaust gas after burning without causing automobile exhaust pollution. At the same time, a machine for absorbing exhaust gas is installed around the engine, which can be used when the exhaust gas cannot be decomposed automatically after gasoline combustion.
If I were an expert in environmental protection, I would build a waste gas treatment plant next to various factories and connect the chimneys that emit black smoke from those factories with the pipes of the waste gas treatment plant. The black smoke goes through the pipeline to the waste gas filtering room, and then through the pipeline to a huge air disinfection room. After a period of disinfection, a pipe is used to discharge fresh air into nature.
If I were an environmental expert, I would install a bacterial sensor underground. If someone spits everywhere, as long as the sensor receives the information, it will inform him in the shortest time and tell him not to spit again. If they don't accept the advice, they will notify the nearest cleaner with an induction transmitter, so that they can criticize and educate the spitter.
If I were an environmental expert, I would plant more flowers and trees all over the world, so that all parts of the world would be covered with green. Let's live in a better environment and breathe fresh air.
Now, I want to learn all the subjects in a down-to-earth manner, lay a solid foundation for realizing a beautiful ideal, and work hard for realizing a beautiful wish.
Do you know what environmental protection means? My understanding of environmental protection is "saving".
Saving means saving resources. For example, once I found a child left the faucet on after washing his hands, I would tell him first, "Turn off the faucet after washing your hands, and tighten it, or you will waste as much water as Huangguoshu Waterfall", and then I would help him tighten the faucet. There is also saving electricity. In broad daylight, there is no one at home, and the lights are still on, which wastes a lot of electricity. Turning off the lights when people walk and using energy-saving lamps can also save a lot of electricity.
Saving means developing good living habits. For example, once Zheng Xiaolong went shopping to buy an eraser, I asked him, "Have you used up your eraser?" He said, "No!" I said, "We should learn to economize. We don't need to buy some things first, and then we will buy them when we run out. " In addition, the back of used exercise books and exercise papers should be used as toilet paper. When shopping in shopping malls, use degradable plastic bags and try to use your own reusable shopping bags. Try not to use disposable chopsticks when eating in a restaurant. Disposable chopsticks are really convenient, but the hygiene is not up to standard, which wastes forest resources. Dad looked it up on the Internet. Every year, China consumes 45 billion pairs of disposable chopsticks, consumes 6,543,800 cubic meters of wood, and needs to cut down about 25 million trees, reducing the forest area by 2 million square meters.
I think we primary school students should start from ourselves and form good habits, which can also be regarded as supporting environmental protection work.
It's really hot today! The sun is burning outside, and the home is as hot as a steamer. There is no air conditioner at home, so I said to my mother, "Mom, it's very hot today. Why not turn on the air conditioner? " Mother said, "You will go upstairs and do your homework later. Go to your room and turn on the air conditioner. " "Why don't you open the living room downstairs? Aren't you hot? " I asked in confusion. Mom said, "There are many advantages to not turning on the air conditioner downstairs. First, save electricity. The living room downstairs is big and few people. Is it necessary to turn on the air conditioner? Besides, turning on two air conditioners upstairs consumes more electricity. Now advocate a low-carbon life. Second, staying in an air-conditioned room all day is not good for people. They are less likely to get sick if they sweat more. " "Oh" I didn't expect my mother to talk so much.
After lunch, grandma wants to turn off the air conditioner in the restaurant. I said, "After a while, why should I turn off the air conditioner?" Grandma said, "aren't you going to the bedroom to turn on the air conditioner and take a nap?" I said, "I want to read here for a while." Grandma said, "It's still a little cold after turning off the air conditioner. We should also learn to live a low-carbon life. " "Oh" I nodded.
We are studying low-carbon environmental protection now, and we will make our home more beautiful and beautiful in the future!
Low carbon and environmental protection, I'll go first.
The earth is the only home for mankind at present, and it is now scarred.
The earth is forgiving a group of ungrateful guys, who are also human beings! Humans throw broken glass bottles at the seaside, and after a few years, they find that the original waste has been washed into colored pebbles by seawater! Why? Why? Why? The earth forgives humans so much, but humans can't let go of the earth?
The earth is finite, and we can't imagine it is infinite. One day, mankind, you have dug these mineral deposits for hundreds of millions of years. At that time, can you regret it in time?
The answer is yes: it is too late.
From now on, it may not be too late.
Do you know that?/You know what? Do you know that?/You know what? When shopping, we always take that plastic bag away by accident. If this plastic bag is thrown into the sea, it will be eaten by turtles and put into the forest. The oil residue inside will attract animals and produce waste gas when burning. Have you ever thought about it? Inadvertently, for convenience, what have you caused! Although it is only fifty cents, the pollution it causes is far more than fifty cents!
For the earth and ourselves. It is best to walk, ride a bike and take a bus when going out. In short, it is to minimize exhaust emissions. Also, it's summer, so it's best not to lower the air conditioner to 24℃, and waste paper, scrap metal and plastics should be recycled. Washing your face and feet can also be used to flush the toilet. We are using the computer now. As long as we dim the screen, we can save electricity. Save electricity and a drop of water for ourselves!
For what we have done, for the earth and for us, plant a tree from now on!
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 an unshirkable activity of human beings. Environmental protection action, at present, is difficult, but a visit can let me see the immature environmental protection behavior in the world.
On this day, my friends and I went to the park to play. There are so many people in the park that it is too crowded to walk. We finally came to a place with few people. Under a big tree, each of us took a photo that satisfied us. We should all take the best photo as a souvenir. Just as I pressed the shutter, the wind suddenly blew. A piece of candy paper abandoned by others has become a "butterfly" flying in the air under the breeze. A lady in fashionable clothes walked past the candy paper. It seems that she didn't see this eyesore, and she still walked on her own catwalk and walked leisurely. In a short time, a gentleman came face to face, wearing a straight tuxedo and shiny leather shoes. He was handsome, but he left with his head held high.
Only the lonely candy paper is left, which looks ugly under the sunshine, in sharp contrast with the beautiful scenery, which is very uncoordinated.
Soon, the wind blew harder and harder, as if God were crying. I think it must be hard for Grandpa Earth to see his descendants treat him like this. At this moment, a little boy ran over and caught the "butterfly". I think he is very naive, playing with the candy paper all over, but he holds the candy paper again and again, without a smile and with a serious face. And this candy paper is like playing hide-and-seek with him. When he tried to catch it several times, the candy paper was blown away by the wind, but he didn't lose heart. He jumped again and again and finally caught it, but he tripped over a stone.
He stood up, regardless of the dust, regardless of his own embarrassment, regardless of the ridicule of others, and chased him up. Somehow, the wind stopped and the candy paper didn't fly. The little boy threw the last fruits of his labor into the dustbin. He smiled so brightly. ...
My hand unconsciously pressed down and recorded this exciting moment. ...
Earthquake, sandstorm, natural revenge again and again, do people wake up? The felling of trees and the drying up of Sete Caidas Waterfall have not awakened people. Are they just complaining about nature after casualties? Wake up, human, what's the use of a moment of happiness? What about money? It is better to invest in environmental protection and make the earth beautiful again.
Don't let us hear the cry of Mother Earth again. ...
Today is an extraordinary day, because after voting, I was successfully elected as a member of the water and electricity saving Committee in my class.
Today's election process is quite intense. First of all, I ran for the post of green guard, but unfortunately I only got three votes and was not elected. I was really anxious! But I'm not reconciled. When I elected the water and electricity saving staff, I bravely recommended myself again. Standing on the podium, facing the whole class, I introduce myself as having the following advantages: being conscientious. Father sometimes forgets to turn off the speaker, computer and lights, and I always find out and help him turn it off. At the moment when the voting results were announced, my heart was pounding with nervousness, fearing to miss the chance of being elected, but to my excitement, I became the class electricity saver with the highest number of votes.
I can be a glorious energy-saving and environmental protection emissary. I should thank my classmates for their support and trust. I will do this job dutifully and live up to everyone's expectations!
In recent years, the pollution in our country has become more and more serious. Part of this river is polluted, and the small fish has no home. The clear river is dirty and there is a lot of rubbish floating. There are also automobile exhaust pollution, factory chimney pollution, vehicle noise pollution and so on. "The environment contacts you, me and him, and cleaning and protection depend on everyone!" I really want to be an environmental defender and do my part to protect the environment.
Automobile exhaust is inevitable every day. In the future, with the development of science, almost everyone goes to work by subway, which can not only avoid tail gas, but also ensure smooth traffic. The subway is also more convenient and faster than driving. Driving is a one-way street in some places, and construction in some places can be avoided by subway. Moreover, driving by yourself consumes oil, which is a non-renewable resource, so oil is very precious. Fuel saving is imperative!
The pollution of chimneys is also very serious. Some factories emit a lot of black smoke, which pollutes the environment of residential areas. So I suggest that factories stay away from residential areas to make the environment in residential areas better.
What would the world be like without sanitation workers! Let's cherish the hard work of sanitation workers. Let's raise our awareness of environmental protection and have a beautiful home together!
