Fourth grade environmental protection composition

Fourth grade environmental protection composition 1 Dear Mom and Dad:

Hello!

Remember to describe your childhood to me? During the summer vacation, I swam and fished in the pond in front of my house. When I was hungry, I picked the lotus flowers in the pond to satisfy my hunger. Winter vacation is coming, skating, snowball fights, thirsty, eating a handful of snow is the best tea. What I see now is that in the black stream, white garbage like plastic bags can be seen everywhere, giving off a stench from time to time. Rain is called "acid rain". It seldom snows again, but it also becomes "acid snow", and it sends out "smog" warning from time to time. I often wonder why there is such a big gap between us. The earth is beautiful because of flowers and trees, but now it is ugly because of garbage and pollution.

Mom and Dad, we have all seen a public service advertisement. In other words, when an old man riding a tricycle to collect waste products rode uphill, a group of children helped him push the car, and the old man climbed the slope easily. A man finished his drink and threw the drink can into the trash can at a distance, but the drink can almost fell out of the trash can. A young man who was doing morning exercises happened to pass by and picked it up in the trash can. So as long as we lift a finger, we can bring us more harmony and beauty. I went online to Baidu, and there are 64 * * in the world. 7.7 billion people. I think if everyone leaves one piece of garbage every day, there will be 64 more pieces on the earth. 7.7 billion pieces of garbage, if everyone picks up a piece of garbage, can Mother Earth be clean and beautiful every day?

Mom and dad, I suggest that our whole family start from today and start from ourselves.

In order to form the good habit of being polite, protecting the environment and not littering, we should:

1, don't litter, throw them into the trash can by category.

2, don't smoke in public places, don't throw cigarette butts.

3, try to reduce driving, reduce exhaust emissions, don't throw garbage out of the window.

4. Don't spit, scribble or paste.

5, rational use of resources, reduce paper waste, put an end to white pollution.

Let's work together to protect the environment and find a beautiful earth.

If my proposal is correct, my parents must not forget to give me a compliment.

I am here to convey

welcome

Love your daughter: Hu

Every time I see the garbage beside the trash can, I think of one thing.

It was an afternoon last month, and I was walking down the street with great interest. I saw an uncle smoking a cigarette and threw it on the ground. I didn't care at all, and I didn't feel shy. I started smoking another cigarette and talked to someone at the same time. An ecstatic expression. I stepped forward and bravely said to the uncle, "You can't litter and destroy the environment." My uncle said fiercely, "Mind your own business and get out." I listened and walked away. After he finished his second cigarette, the clean ground was destroyed. At this moment, a cleaner came up and said confidently, "You should throw it in the trash can." Instead, he said angrily, "If I lose it, you should sweep it." The cleaner said, "If people all over the world are like you, the world will become a garbage world. Would you like to live in a dirty and smelly world? " If we are all like that uncle, there will be rubbish everywhere on the ground, mosquitoes and flies will fly everywhere, and diseases will wander in the crowd like the shadow of the devil.

Therefore, I want to say to everyone: "It is everyone's responsibility to protect the environment."

The fourth grade composition 3 protects the environment, and the trickle is crystal clear, and the spring water makes a crisp sound. The rolling mountains stand tall, and the majestic spirit is overwhelming; The lush trees stand tall on the top of the mountain, showing a fearless look; The wild flowers blooming on the top of the mountain have different shapes and compete with each other, and the fresh flowers are refreshing. But everything in the past has become a memory. Facing a muddy river, batteries and plastic bags have polluted the earth, industrial waste gas and automobile exhaust have polluted the air, and trees and flowers are hard to see, only withered trees and flowers can be seen, and everything has disappeared, and a red alarm has sounded on the earth. Presidents of various countries held a meeting for three days and nights ... "All people moved to the moon". After discussion, they issued such an order. According to the observation of scientists, the destruction of the earth is so serious that mankind is not far from the end of the world. If we don't leave the earth, then mankind will have to count the days and wait for death. Today's moon, jointly built by human ancestors and modern humans, has a new look.

Lush Woods, crystal clear rivers, flawless blue sky, and all kinds of flowers and animals. "wow! This seems to be a new earth, which brings us back to the past. " People don't sigh. Yes, now the moon is almost exactly the same as the earth. There is air around the moon, the moon has gravity, and a thick atmosphere surrounds the moon. Everything seems to go back to the past, people have been living here ... "Wow! There are so many trees here! " "wow! There are so many rivers here! " Greed once again took the human hand and went to the abyss …

I don't know how long it took before the moon reappeared and everything on the moon became lifeless. Everything polluted the moon, and the atmosphere became thin and close to zero. The tragedy is staged again. On a certain day in a certain month, a meteorite with a diameter of 40 kilometers broke into the moon, because the atmosphere of the moon was very thin and there was almost no resistance, which made it easy for the meteorite to break into the moon. Because there was almost no resistance, the impact of the meteorite was so great that it hit a big hole in the ground. Hot magma spewed out from the cracks ... at the moment of death, mankind finally woke up, but that awakening is now just a powerless struggle. Ridiculous human beings really can't redeem themselves this time. The world has been destroyed, and mankind has perished. ...

The earth is our home and the mother of mankind. We rely on it and explore it. How beautiful this blue planet is, but we must know that there is only one earth!

Regrettably, many people turn a blind eye to this simple truth and continue to do whatever they want, regardless of the safety of the earth's homeland. Qu, an environmentalist, once said: "Only change can save the fate of mankind, and only change can make our descendants survive." The "change" refers to environmental protection. That's right, so now many people are holding signs and shouting empty slogans in the street, but they don't see much action. Will the pollution get better? Don't!

Look, the rivers in our city are black and smelly; Long queues of cars emit a lot of exhaust gas; A piece of green land has become a "stone forest"; The crisp birdsong disappeared without a trace. If this situation continues, China will continue to lack water resources, the air will become more and more turbid, and 65,438+00% of birds will disappear in this century. The above things, we humans are the culprit!

Everyone knows that trees can absorb carbon dioxide, release oxygen and purify the air, which is a necessary condition for our human survival. However, some people cut down trees for money, which leads to excessive soil erosion, serious damage to the earth's vegetation, and desertification of oases and cities, threatening our human survival. As for the disposable chopsticks we usually use, it consumes dozens of acres of forest every day. In the eyes of those people, trees seem to have no value except furniture and building materials. Does anyone not understand what trees mean to us? Our living area is already very small. If we go on like this, we may even lose our only land. In addition, the Yellow River, our mother river, has become one of the most polluted rivers in China in recent years. We can't watch the Yellow River dry up from our hands, so many environmentalists have studied plans to control the pollution of the Yellow River and tried to improve its water quality. But without our participation, the Yellow River, the cradle of our life, will run dry and die.

If we destroy the environment again without restraint, we will naturally be punished. Those catastrophic floods claimed countless lives. Due to the greenhouse effect, glaciers in the Antarctic and the Arctic melted, resulting in rising water levels and seawater flooding coastal areas, causing serious economic losses. Isn't this the best proof?

Guangning, my hometown, relies on Zhuhai eco-tourism to develop its economy. Nowadays, the environment of some bamboo forests is very chaotic, and people complain. Eco-tourism in Zhuhai is the foundation of our development in Guangning. If the roots are destroyed, how can we grow lush branches and leaves and produce beautiful flowers?

Let's be kind to human beings and nature! I wonder if you have read the article "100 things you can do to protect the environment". In fact, we can do many things. For example, plant a pot of flowers and a tree on Arbor Day; Protecting wild animals is the balance of ecology; Cherish water resources and don't dump garbage into rivers; Being a little environmental guardian, using every green anniversary to promote environmental awareness, so that green mountains always exist, green water always flows, and the soil always smells ... these are all things we can do. Why don't we want to practice?

Now, the ecological environment of the earth is getting worse and worse, and the environmental alarm has sounded. Let's join the ranks of environmental protection, create a bright future in which man and nature live in harmony, and let man and nature live endlessly!

With the development of human economy, there are more and more garbage, and there are only a few ways to deal with garbage, either landfill or incineration, which makes the living environment of China people worse and worse.

"Young man, you have to sort the garbage!" "Old man, what's it to you?" "If you do this, you will pollute the environment!" Uncle Zhang tried his best to explain that the young man finally knew the importance of garbage sorting after listening.

I used to hope that the garbage truck below would be sent away quickly, so as not to have a bad smell below. After listening to Uncle Zhang's teaching today, I have a new understanding of garbage. We humans produce garbage every day, but where does our human garbage go after it is thrown out? First, the workers send the garbage to the dump and then bury it underground. The cost of landfill is relatively high, ranging from about one ton in 450 yuan to 600 yuan, which is enough for children in poor mountainous areas to support for half a year. Besides, if it continues to be buried underground, it will take up a lot of space and attract mosquitoes.

You will often see four kinds of trash cans in the park, namely: recyclable garbage, non-recyclable garbage, harmful waste and other garbage. Recyclable garbage is blue, non-recyclable garbage is green, harmful waste is red, and other garbage is gray.

Garbage sorting seems to be a simple project, but it is not a simple project if you don't pay attention to it. But if you want to do it every day, it's a complicated project. It is because of it that teenagers can learn it. With it, the city will become beautiful, with it, even the whole country will become beautiful.

Throughout the ages, Mother Earth has nurtured countless descendants with sweet milk. It turned out that she was beautifully decorated by her younger brothers and sisters. But now, there is a phenomenon of wasting resources and destroying the environment everywhere in life-the tap keeps flowing out of clear tap water, but the water users don't know where it goes; The room was empty for a long time with the lights and TV on. The streets are full of rubbish. Broken branches float on the river ... this phenomenon can be seen everywhere. Can't we do better?

I once heard a story about water: people are rich, but they always waste water resources, and as a result, water resources are used up. Nothing grows on the earth, animals and humans are extinct ... the result of wasting water is too heavy for people to imagine.

The earth is where we human beings live, and it generously provides us with living resources and conditions like our mother. Cherish all the things worth cherishing in the world, otherwise when you lose it, you will regret why you are so extravagant and why you didn't find it so important to yourself. Therefore, we should cherish resources, but definitely not from the perspective of money, but for our own lives and the lives of all things in the world. So we should protect the earth, cherish natural resources and protect the environment!

Today, I went to the park, and I saw the sign "Don't destroy trees, don't litter". Later, I saw a child throw the tape on the ground and I rushed over. Tell children:' Don't throw rubbish, pick it up'. Later, he picked it up. I'm glad to go home.

I am very happy. Come and protect the environment!

When you go out, you can see disposable plastic bags "white garbage" that pollute the environment everywhere. In fact, most plastic bags sold in the market are made of polyoxyethylene. This chemical substance will release toxic substances when it meets high temperature, which will enter the human body with the air and endanger people's health.

At present, the main way to treat plastic waste is to fill it in ditches and bury it. But this method is only temporary for it, because it is difficult to be decomposed in soil, and it will produce harmful substance hydrogen chloride under the influence of heat and radiation, polluting soil and groundwater.

So I suggest that you use less disposable plastic bags, don't be afraid of trouble, and use more environmental protection bags such as cloth bags.

Nowadays, people use a lot of disposable chopsticks. How much wood can be saved if people try to use sterilized chopsticks! But now people don't realize this, but cut down a lot of trees and make disposable chopsticks. Slowly people will know that doing so will destroy the environment and cause great harm.

Students, start with us, use less plastic bags and disposable chopsticks, and protect the environment from me.

Protecting the environment, these four words are not unfamiliar to everyone, but all of us have been talking about protecting the environment, but we have failed to do so! After reading my composition, you should feel the importance of protecting the environment!

If there are two photos of the future scenery in front of you, one photo is that everyone will protect our beautiful home. The blue sky is endless, white clouds, beautiful grass, mountains and plains, clear rivers, crystal clear, beautiful flowers, enchanting thousands of tall trees, soaring into the sky, fresh air, I can't help it. The warm sun shines high in the sky. This photo can also give you beautiful scenery in everyone's mind! This is the result of protecting the environment!

In another photo, plastic bags are floating in the dusty gray sky, and garbage is everywhere, which is a mess, PM2. Five record-breakers! Everyone wears a mask. This is the result of people not protecting the environment!

A garden city, a dusty painting, two paintings, two different results, which one do you like?

It is the wish of everyone and everything to make every corner of the world pollution-free. So let's create a beautiful and peaceful world together!

Automobile exhaust pollutes the environment, so that nature does not order the beautiful world. The carbon dioxide emitted by tail gas makes trees and many plants absorb a lot of carbon dioxide. So everyone should drive less private cars, take more buses and ride more bicycles. Remember to exercise more!

Many factories have brought many worries to the source of human life. For example, discharge sewage. The discharged sewage will do harm to all living things in the water. Sewage will walk along rivers and streams, and it is possible that sewage will spread all over the world no matter which day! Sewage will stink if left for too long, and so on. So please tell those people in the factory not to discharge sewage any more! Don't let the last drop of water turn into your tears.

The chairs, tables and cabinets beside our stereo are all made of trees, and trees are also our good assistants. They are our good assistants in floods and landslides-trees protect us. The air we absorb is also the credit of trees! If there were no trees, it would be like losing all our luster for us! The world must be gloomy ... please don't hurt them!

When a person goes to a park, campus, home or scenic spot ... he will throw garbage, but have you people who throw garbage everywhere ever thought about how harmful garbage is to human beings? In summer, there is more garbage. Of course, the hot sun shines on the garbage, and the garbage will slowly rot. At night, the smell will be everywhere! So please take care of the environment and don't litter! Don't mistake it for garbage! Don't let the bad smell pervade the world.

Finally, I only say one thing: it is everyone's responsibility to care for the environment! Add more glory to the world! Come on, let's go!
