In life, work and study, it is inevitable for everyone to come into contact with or use composition. With the help of composition, people can reflect objective things, express thoughts and feelings, and convey knowledge and information. Still at a loss for composition? Below are 10 fourth grade environmental protection essays that I collected for you. You are welcome to share them. Fourth Grade Environmental Protection Essay Part 1

Recently, the temperature around the world has been warming, mainly due to excessive levels of carbon dioxide, methane and nitrous oxide, all caused by human beings' continuous destruction of the environment.

Cars are speeding on the road and it is very enjoyable to drive. In fact, the exhaust emitted by cars is one of the main causes of air warming. We should be environmentally conscious and ride more bicycles to reduce exhaust emissions. Cars Exhaust gas is also harmful to the human body, so we should drive less.

In addition to car exhaust, there are also methane gases emitted by livestock industry and large-scale felling of trees, which are also the main causes of global temperature warming.

Global warming has also greatly affected agriculture. The production of crops requires a large increase in water, resulting in a serious shortage of water resources. Coupled with natural disasters, it will be even more serious.

Global warming will cause continental glaciers and mountain glaciers to gradually melt, and the amount of sea water will increase. In this way, animals in the Antarctic and Arctic will be homeless and gradually die out.

Global warming will also reduce our living area, because rising temperatures and photochemical reactions of chemical pollutants accelerate the excess of photooxidative oxidants, which can cause many human diseases, such as chronic bronchitis inflammation, emphysema and other diseases.

So for the sake of our living environment, let us protect the earth together and let Mother Earth restore her original appearance. As long as we ride more bicycles, plant more trees, and use less chemicals, we can make the earth green again. , let us start from ourselves and protect our precious earth.

In a large dense forest, there lived a lively and cute little white rabbit.

One day, the little white rabbit was playing in the forest. I don't know who threw the eaten instant noodle bag on its head, and the instant noodle dregs were scattered all over it. The little white rabbit said angrily: "Who doesn't care about the environment so much that he throws garbage on others?" The little white rabbit had to go home and take a bath, and finally washed off the dirt on his body. The next day, the little white rabbit went out to play again, and someone threw the juice bag on it, and the remaining juice spilled all over it. Now the little white rabbit was furious, and it shouted: " It’s really annoying, I must leave this place where this happened 1

The little white rabbit looked again and again, and moved to the grass, but the grass was sprayed with pesticides, which almost killed the little white rabbit. Poisoned to death, the little white rabbit had to move elsewhere.

The little white rabbit thought again and moved to the field, but the sewage in the river flowed into the field. Elsewhere.

The little white rabbit searched and searched, and moved to the hill. But people cut down the trees to build houses, and burned up the grass with the sparks left by the fireworks. White Rabbit was very sad and thought: These good places have been destroyed by people. It’s better to live in our previous home. I’d better move back!

However, something unexpected happened. The little white rabbit suddenly fainted. When the little white rabbit woke up, the little white rabbit asked the woodpecker to peck some words on the tree - "People!" Please don't destroy the environment, protect the environment, protect the environment 1 Fourth Grade Environmental Protection Composition Part 3

A small river flows in front of grandma's house. Duckweed and water peanuts spread all over the river, and all kinds of garbage lay in it like flowers. In summer, the stench fills the sky and flies fly. People walking by the river can't help but cover their noses or hold their breath. Whenever grandma stands by the river and "appreciates" the "beautiful scenery" of the river, she always sighs. Once, I couldn't restrain my curiosity and asked my grandma what she was sighing about. So, through my grandma’s narration, I “saw” the beauty of the creek:

At that time, there were rows of thick willow trees beside the river. They always liked to hang their long hair into the water, and the water surface became The brightest mirror. The breeze blew by, ripples appeared on the river surface, and the river was like green silk fluttering gently in the wind. The river water is more transparent than egg white and sweeter than sugar water. Ducks and fish are swimming and playing in the water.

On the pier, there was an endless stream of people fetching water for cooking and washing vegetables... In my mother's memories, I heard the noise of the creek: the creek was my mother's natural playground when she was a child. They often use rice baskets to catch small fish and shrimps, and they feel happy watching the little guys jumping in the rice baskets. Sometimes I want to try something new, so I step on the slippery mudflats and pick up snails and river mussels. If I'm lucky, I might catch a tortoise... When the weather is hot, children and adults are soaking in the river, and the water is splashing on the river. There was constant laughter.

It’s just that in my eyes, the fish can’t swim, the boat can’t move, and it doesn’t have the beauty and vitality of the past at all? Is it true that the continuous development of society must come at the expense of a harsh environment? Fourth Grade Environmental Protection Essay 4

As the world that humans explore becomes larger and larger, the environment of the earth, the mother of mankind, is also becoming more and more bad. Strengthen environmental protection efforts to further promote sustainable living. is imminent.

Let’s take the global warming that everyone knows about as an example. If the current rate of global warming is calculated, 90% of the Arctic glaciers will melt in ten years; if the global average temperature rises another 1 degree Celsius, the glaciers on the Himalayas will melt; if sea levels continue to rise, then like Coastal cities such as Qingdao and Shanghai are in danger of being swallowed by the sea.

As for sandstorms, you must have often heard about them recently: the sandstorms in the Hunshanda Desert in Inner Mongolia have become a frequent visitor to the Beijing-Tianjin area. This is no surprise, but you know what? There were five sandstorms in the 1950s, but by the 1990s, the number had increased to 23! In 1979, 1983, 1986, 1993, 1995... the economic losses caused by sandstorms are increasing. You must know that sandstorms are warnings of land desertification, and the increase in the frequency and intensity of sandstorms is a warning of land desertification. Sounding the alarm for the ecological crisis!

You must know that this series of disasters are caused by human beings. Here, I hope that everyone can live a sustainable life, which refers to the rational use of various resources and the planned intake of natural resources. , a healthy lifestyle that does not burden the environment. At the same time, I hope that everyone will start with the small things around them to protect the environment and protect our mother, the earth.

There is an environmental saying: a polluted smoke turns white pigeons into black crows; pollution of the atmosphere turns living beings into charcoal.

Now our environment is suffering from all kinds of damage by humans, including littering, trampling on flowers and plants, hunting and killing animals, etc... I seem to see the grass crying, The animals are on the run and the trashcan mother is constantly looking for her children.

If you put a green little environmental protection guard badge on me, I will use my next actions to tell you that I am qualified.

I will find a plastic board at home, write "Green - from your hands" on it, and then stand on the grass. I seem to see the grass blooming its smiling face again. I will also put a sign on the trash can that says "I have a huge appetite, so I can fit all the peels and confetti", and the trash can mother also laughs. I also want to say to people who hunt animals: "Protecting animals can achieve ecological balance and receive the love and care of Mother Nature. Otherwise, you will be punished."

I hope that my next actions will come true and become a A qualified environmental protection guardian! Fourth Grade Environmental Protection Composition Part 6

On Sunday morning, the sun was shining and the breeze was blowing. My sister and I went to the square to exercise.

Come to the square, hey! There are quite a few people exercising. My sister said, "Let's run!" "Okay." Just after running for two steps, a gust of breeze blew a black plastic bag into my face. "It's really disappointing. Such a good mood has been ruined by this plastic bag." Mixed up!" I muttered. My sister said, "Yes, look, there are quite a lot of plastic bags here. How about we pick them up so they don't fly into other people's faces again." "Okay, okay." I clapped my hands in agreement.

Just do it. My sister bent down and picked up a plastic bag next to me. I didn’t show any weakness and ran to pick it up immediately. As soon as I got there, the plastic bag flew away as if it was playing hide and seek with me. , looking at that posture, it seems to be saying: "I just won't let you catch me, I still want to stay here for a while!" I was so angry that my sister looked at it and smiled and said to me: "You run away It's so fast and the wind blows, can the plastic bags not run away? "So that's it. Under the guidance of the "expert", I picked up many plastic bags very smoothly.

We couldn't be happier to see so many "captives" in the hands of my sister and me.

On the way home, I thought to myself: Today has been really meaningful. I have exercised and protected the environment. I have become a little environmental protection guard. It really kills two birds with one stone! Fourth Grade Environmental Protection Composition Part 7

Nowadays, human science and technology are becoming more and more developed, and our lives are getting better and better, but our environment is threatened.

Mercury is a highly toxic heavy metal and is a harmful component contained in waste batteries. This harmful ingredient will cause great harm to the human body and is very destructive to the human central nervous system. The Minamata disease that shocked China and foreign countries in Japan in the 1950s was caused by mercury pollution. If used batteries are mixed with domestic garbage for landfill or thrown away casually, the leached mercury and heavy metal substances will seep into the soil, contaminate groundwater, and then enter fish or crops, destroying the human living environment and indirectly threatening human health. healthy.

In addition to the mercury in used batteries, plastic bags are also extremely harmful to the land. It will change the pH of the land, affect the absorption of nutrients and water by crops, and lead to reduced agricultural production. As for plastic products discarded in water or on land, they not only affect the environment, but can also lead to death if swallowed passively.

In our daily life, some people bury or throw waste batteries and plastic bags into the water. They think that this is a proper disposal, but in fact it is not. Doing so will not only pollute the water Resources and land resources can also endanger one's own health...

We live on this land and we must try our best to protect it. We must not destroy the land and environment. Protecting the environment is everyone's responsibility. Fourth Grade Environmental Protection Composition Part 8

On the National Day, I followed my brothers and sisters from the Green Environmental Protection Association of Zhejiang University of Technology to be an environmental protection guard. I felt very excited.

The theme of the activity we participated in is "Keep the Garbage on the Ground". We need to distribute environmentally friendly bags to tourists so that they can take melon peels, shells and other garbage out of the scenic area. This not only protects the environment, but also reduces the burden on sanitation workers. burdened.

The mission began. I first found an uncle who was eating oranges. I thought he might need a reusable bag. I stepped up and asked, "Hello, uncle, we have some bags today." This is an activity to keep garbage on the ground. We want to call on everyone not to litter and take them out of the scenic area. Do you need a reusable bag?" After hearing this, the uncle said with a smile: "Thank you, I don't need it." "I obviously felt a little frustrated, but I didn't lose heart. I thought carefully about whether I had said anything wrong just now. "Oh, maybe I shouldn't use the question. Maybe it would be better to try another way of saying it," I said to myself.

I found another aunt who was eating melon seeds. I stepped forward to introduce our activity to her and said: "I can give you a reusable bag, which can be used for garbage." The aunt listened. After receiving it, she replied: "Oh, thank you so much, I'm just in need of this!" I quickly handed her the reusable bag and was about to turn around when I heard my aunt calling me from behind: "Hey, little girl, there are more here. Two young ladies, please send them as gifts too! "Haha, what a great harvest! So many were given away at once.

The event is over. I gave away twenty reusable bags in one ***. Although what I did was just a small thing, I think it was worth it if it could reduce the work pressure of the sanitation workers. . In life, we should also take care of the environment around us, starting from the small things around us, not littering, let alone adding burden to the hard-working sanitation workers.

Today, the human earth is facing an unprecedented crisis. The sky is no longer blue and the river water is no longer clear. Animals are becoming extinct at an accelerated pace, and people's living environment is getting worse and worse. The increasing content of carbon dioxide in the air is causing the earth's temperature to increase day by day, so everyone is aware of the need to support low-carbon environmental protection. I also suddenly had a little dream: a small environmentally friendly invention—an all-round automatic purification robot.

The idea is to design an environmentally friendly robot.

But it does not need to be controlled by humans. Instead, it has an automatic detector that can detect the quality of the surrounding air at any time. Once there are pollutants in the air, the robot will turn on the automatic cleaning function and open its big mouth. Mouth, inhale harmful gases into the "mouth", decompose the harmful gases, and then release fresh and oxygenated air. In this way, we can all breathe fresh air at any time.

There is also the seriously polluted river water. Today's rivers have suffered a lot of industrial pollution. Fish and shrimps have disappeared, and the river water has become filthy. Everyone needs to take immediate action to rectify the river water. So the robot I conceived can turn its arms into two water pipes. One can reach into the river water and filter out the bacteria flowing into the river water, while the clean, mineral-rich river water flows from the other pipe. Slowly flow out, so that we can see the fish jumping alive and full of life again. Then every drop of river water will be as radiant as dewdrops.

Also, as technology becomes increasingly advanced, agricultural pollution is becoming more and more serious. Garbage and environmental pollution that can be seen everywhere have reduced crop harvests, and farmers are worried. The robot I conceived can suck garbage into its "belly" at any time, transform the garbage in the body, turn it into treasure, and create fertile nutrients to make crops grow more vigorously. This not only protects the environment, but also benefits the ecological cycle.

This is the all-round automatic purification robot I envisioned. What do you think? I believe that with it, our environment will get better and better, and our homes will become more and more beautiful. The earth in the future will also be the most beautiful planet in the universe!

In the spring of March, everything revives, the willows are green and the flowers are red, and the earth is full of vitality. In such good weather, our little reporters take action and transform into little environmental protection guards to promote Earth Day and protect the environment. It starts with me, I can do it.

In the afternoon, my parents and I gathered at Chengshan Square. At the check-in desk, we got a task sheet for the "treasure hunt" activity of parent-child adventure. There are 6 missions including kangaroo jump, crossing single-plank bridge, two-person three-legged, acupressure board, tacit understanding competition, and taking photos.

I found two children at the check-in area, they were boys, and then we formed a group. We used a garbage bag and put on gloves and we set off to look for garbage and garbage discarded by tourists in the scenic area. The mission is over.

We picked up a lot of rubbish along the way and completed 6 level-breaking activities. What impressed me most was the acupressure board and the tacit understanding competition. Let’s talk about the tacit understanding competition: write several animal names or familiar names on the cardboard, let two people face each other, one person can see the words written on the cardboard, and the other person can’t. The person who sees it has to act out what is written. That thing, another person has to guess what it is. It felt very exciting and fun. I told my mother that I would write a few for fun when I got home.

In the end, we completed 6 levels together, and my mother finally collected 20 likes. We all completed the task perfectly. I also made new friends and learned new environmental protection knowledge. Very happy, we all went home happily in the end.
