There is only one world to write 400 words in a composition.

In real life or work and study, everyone is familiar with composition. According to different genres, composition can be divided into narrative, expository, practical and argumentative. So, how to write a composition? The following is my carefully arranged 400-word composition to write that there is only one earth, hoping to help everyone.

There is only one earth in 400 words, 1. These days, we learned a text called "There is only one earth". After reading it, I know one thing: the earth is the mother of mankind and the cradle of mankind!

According to the description of the astronauts who were lucky enough to fly into space, the earth they saw in space was a beautiful, crystal-clear and only living planet, surrounded by a thin layer of water-blue tulle. The earth has always made selfless contributions to human beings, but because human beings don't know how to cherish, develop unrestrained and destroy at will, not only the natural resources of the earth are getting less and less, but also a series of ecological disasters have caused a threat to human survival. For example, in July 1995, an incident occurred in our country: several factories discharged excessive sewage and smoke into the ocean and atmosphere, which led to a large amount of acid rain decline and destroyed a large area of forests and crops. This not only pollutes the environment, but also causes serious losses to natural resources.

Our earth is both lovely and fragile. Students, scientists have already proved that there is no second planet suitable for human habitation within 40 trillion kilometers of the universe centered on the earth. Humans can't expect to move to other planets after destroying the earth.

There is only one earth, citizens of the earth, wake up! Let's start with protecting every grass, tree, mountain and water around us and take action. Let's protect the earth, our home!

There is only one earth in 400 words. I learned the text "There is only one earth", which deeply moved me. The author used his own pen to expose the evil deeds of human destruction of the earth.

Our earth looks lovely, but it is too fragile.

The earth, like its mother, selflessly provides human beings with water resources, air resources, forest resources and mineral resources ... However, due to the uncontrolled exploitation and random destruction of natural resources, the resources on the earth are rapidly drying up. In addition, human abuse of chemicals has caused a series of ecological disasters. Isn't the frequent earthquakes and tsunamis in recent years a wake-up call from the earth?

You may think, isn't there a second earth in the vast universe? Scientists have confirmed that there is no second planet suitable for human habitation within at least 40 trillion kilometers centered on the earth. What is the concept of 40 trillion kilometers? At our current plane speed, 40 trillion kilometers will take at least 6 million years to fly. Let's think about it. How can anyone immigrate to live there at such a long distance?

The earth is the mother of human beings and the cradle of human life. She is ordinary and great. The water resources, forest resources, atmospheric resources and biological resources needed by human beings are renewable, but these renewable resources have become non-renewable resources because of human abuse of chemicals.

Because human's ... has caused ... a great threat to human survival.

"Our earth is so lovely and easily broken!" This is the sigh of astronauts when they travel around the world.

There is only one earth! There is only one earth! There is only one earth! ……

We must carefully protect the earth and better benefit our future generations!

Once upon a time, the biggest dream of mankind was space travel. Today, hundreds of years later, human beings have realized their dream of traveling in space. Astronauts said that the earth seen in space is a crystal clear blue sphere, which looks so amiable and the surrounding stars are so bright.

Mother Earth has generously given us many natural resources. Mother Earth provides us with resources without restraint, while human beings wantonly destroy nature, and slowly many natural resources are exhausted. However, human beings are still stubborn and abuse the natural resources given to us by Mother Earth, so that animals can witness the destruction of their homes, the towering trees falling down and the squirrels on the treetops standing unsteadily. Because there are no big trees, sandstorms are raging, and nature has repeatedly reminded human beings, but human beings still slowly cut down a tree. Slowly, the ice and snow entrenched on the top of the mountain melted, and nature's revenge finally came. Sea level rise is true, human cities are flooded, and it is human's fault. After all, nature will not spare human beings, which is the destination of human beings. Man has established a base on this beautiful land of the earth, and is constantly moving. Handfuls of shovels record the hard years spent with the earth. In the future, human beings may lean on crutches, their feet are stuck in the mud, their limbs are sound and they are respectful to nature.

Taking advantage of the beautiful scenery now, I raked the soil and picked white wheat in Suixian County, lying on the water to help my daughter cross the shore to catch slugs.

In the vast universe, each planet has its own color, trajectory and change, which is a natural law. However, on the earth, some unnatural disasters and indirect man-made disasters have caused many human deaths.

The earth, the mother of mankind, the cradle of life, her resources will be exhausted. Originally, these resources can be continuously regenerated and contribute to mankind for a long time. However, due to human carelessness, abuse of chemicals, littering, waste of water resources, waste of food, etc., they can not be regenerated, which has also caused a series of ecological disasters: some people died of poisoning because of drinking unclean water; Get sick by sucking bacteria; In the north, how many people die of thirst because they can't drink water; How many people can't take a clean bath for a year; How many people still starve to death because they can't eat? ...

Before the earth, in the morning, the sky was blue and white clouds were floating; At night, the stars are more and denser than the sand on the ground. What about the earth now? Although the sky is blue with white clouds, we can sometimes see black smoke in the sky; There are fewer stars than penguins at night, which are all caused by human beings themselves. Some people say that the universe is so big, why don't we find another planet to live on? Scientists have proved that there is no second planet suitable for human habitation within at least 40 trillion kilometers around the earth, and we can't expect to emigrate to other planets after destroying the earth.

The beautiful Mother Earth is being destroyed by ourselves. Students, we should protect the earth. From now on, we should start with small things, cherish every drop of water and not waste every grain of rice. Let's change the earth back to its original appearance and make it more and more beautiful!

There is only one earth in 400 words. The earth is our only home. We only have one earth. If we destroy our home alone, so will the earth. ...

The world is developing bit by bit, but the earth is also disappearing bit by bit. Nowadays, many people have their own cars, which brings convenience to travel and pollutes the environment. The sewage from the factory was discharged without purification; Convenient bags are also increasing a little; Trees are also decreasing a little. Maybe adults think this is just a trivial matter, but who knows that it is because of these pollution that the ozone layer in Antarctica, the only one that protects our planet, has been poked with a hole. Under the direct ultraviolet rays, the Antarctic ice is melting, penguins are running around, and penguins are dying. The Yellow River is constantly drying up and tap water is being polluted. Some people even have no water for more than 200 days. Do you know that if ultraviolet rays shine on the earth, life on the earth will cease to exist? Imagine how terrible that would be. The universe will be empty. Maybe one day, hundreds of years later, I can't talk or know anything. The earth and the universe are just non-existent objects, because nothing is known.

So, let's protect the earth, drive less, cut down less trees, save paper, save paper, after all, they are not endless.

The earth is our only home; The earth is our only home. Let's protect the earth together!

I read the text "There is only one earth" today, and I have many heartfelt feelings. The beautiful earth looks huge, but it is very small and fragile in the universe. The living environment is deteriorating day by day, and natural disasters occur from time to time. ...

This text is mainly about: our earth is very small and fragile, and the environment on the earth is deteriorating. We live on the earth, not to protect it, but to destroy it to varying degrees. If the earth explodes, we humans will be extinct. Scientists are looking for a second planet suitable for human habitation, but so far they have not found it, so the article tells us that we must protect the earth and stop destroying it.

We humans are very honored to live on this beautiful earth. We should protect this beautiful earth. We should strengthen environmental protection and reduce the damage of harmful gases emitted by factories to the atmosphere; The fresh water resources on the earth are also very limited, so we should start from me and save every drop of water; You can't use those harmful "inventions" that destroy the earth.

Save energy, make rational use of garbage and turn waste into treasure. According to incomplete statistics, the world can produce more than 300 billion tons of garbage every year, which is the result of littering everywhere. It is piled on the ground and floats on the river, and it often gives off a bad smell, which makes people feel disgusting. If we can build some garbage treatment plants to turn garbage into renewable energy and serve mankind.

We only have one earth. As the article said, our earth is very beautiful, but it is too fragile. We should protect it, we have an obligation to protect it, and we must make the earth we live in more beautiful.

There is only one earth in 400 words. The article that impressed me the most was Only One Earth. It introduces the knowledge about the earth, explains the importance of environmental protection, makes me understand how important it is to protect the environment, and calls on everyone to consciously enhance their sense of responsibility for environmental protection. Factories built by people emit a lot of waste gas around and pollute the air; They also discharged a lot of sewage, which flowed into rivers and polluted water sources; People cut down trees at will, leaving the originally dense green hills exposed. When it rains heavily, soil erosion causes many natural disasters. People litter everywhere, and all kinds of rubbish can be seen everywhere along rivers and highways ... can the earth bear it?

People keep saying that "it is everyone's responsibility to care for the environment", but how many people have done it? The earth provides us with such a good environment, but do people cherish it? After reading There is Only One Earth, people should realize their mistakes. In order to protect the environment in the future, don't let innocent lives be lost in your own hands! We must protect the earth more carefully. If we meet an unsanitary person, we should seriously say to him, "There is only one earth!" " "We only have one earth, a blue sky and a home for our own survival. Don't let the last drop of water on the earth become our tears, and don't let the last green leaf on the earth become our food! Let's work together to protect the earth's environment, because we only have one earth!

Today, I read the article "There is only one earth", and I understand why the earth is the mother of human beings and the cradle of life.

According to the astronauts who were lucky enough not to fly in space, the earth they saw in space was a beautiful, glittering and translucent and only living planet. It is wrapped in a thin layer of water blue gauze. The earth has always made selfless contributions to human beings, but because human beings don't know how to cherish, unrestrained exploitation and random destruction, not only the natural resources of the earth are getting less and less, but also a series of ecological disasters, which pose a threat to human survival. For example, in July of 1995, an incident occurred in our country: some factories discharged excessive sewage and smoke into the ocean and atmosphere, which led to a large number of acid rain arrival and destroyed a large area of forests and crops. This not only pollutes the environment, but also causes serious losses to natural resources.

Our earth is both lovely and fragile. Students, scientists have long proved that there is no second planet suitable for human habitation within 40 trillion kilometers of the universe centered on the earth. Humans can't expect to move to other planets after destroying the earth.

There is only one earth, citizens of the earth, wake up! Let's start with protecting every grass, tree, mountain and water around us and take action. Let's protect the earth, our home.

There is only one ingredient on the earth: 400 words and 9 faucets keep running clear tap water, but the users don't know where to go; A room with lights on and TV set empty; A notebook was thrown into the dustbin, but only a few pages were used ... Have you ever seen a similar phenomenon? Have you ever thought that the natural resources on the earth are limited?

I read the text "There is only one earth" and learned a lot. For example, the natural resources on the earth are limited. Yes! Mineral resources take hundreds or even thousands of years to form. The selfless earth has generously provided human beings with mineral resources. But if mining is not controlled, it will accelerate the depletion of mineral resources on the earth.

The water resources, forest resources, biological resources and atmospheric resources needed by human life could have been regenerated and contributed to human beings for a long time. However, because people destroy the natural environment at will, cut down trees indiscriminately, waste water resources and use chemicals indiscriminately, these resources can not only be regenerated, but also cause many disasters, posing a serious threat to human survival.

But many people don't know this and do bad things. Many people fantasize that after all kinds of resources on the earth are exhausted, they will move to other planets to live and give up the earth. It can be verified by scientists, which is an impossible wish.

The earth is so lovely and fragile. So, let's act together to protect the earth!

There is only one composition about the earth: 400 words 10. We always throw away books and stationery we don't use, and we often throw rubbish everywhere. We are wasting the earth's resources and destroying our earth at will.

All our natural resources are limited. Take mineral resources as an example, it is not given by God, but formed by geological changes over millions or even hundreds of millions of years. The earth is selfless, and it generously provides all kinds of resources for mankind. But if it is exploited without restraint, it will accelerate the depletion of the earth's resources.

Don't let the faucet cry, don't let the young trees grieve, don't let the air pollute, don't destroy the ecological balance, don't pick and cut indiscriminately, and don't waste any more.

The water resources, forest resources, biological resources and atmospheric resources needed by human life could have been regenerated and contributed to human beings for a long time. However, we should destroy natural resources at will and abuse chemicals unscrupulously, which will not only make them unable to regenerate, but also cause a series of ecological disasters and pose a serious threat to our survival.

Energy waste is destroying homes, and deforestation is destroying the earth. When we destroy the earth, we are also destroying ourselves. I don't want Mother Earth to cry again!

So we should start from ourselves, from the small things around us, protect our home and protect the earth.

There is only one composition about the earth, 400 words 1 1. On a sunny weekend, my parents and I discussed it for a long time before deciding to play.

On the way, I looked up at the sky and found that the blue sky had become a dark world, covered with a thick layer of smog, as if aliens had invaded the earth. A breeze is blowing, and colorful plastic bags are flying all over the sky, just like white ghosts, invading every corner of the city at will. Passing by the park, I saw that the original crystal clear river turned into a garbage dump, with garbage bags and snack boxes floating on it ... The lawns in the park were all trampled by people unconsciously, and the grass bent over, and people turned a blind eye to the billboards that protected plants.

When I got home, I was still angry. How can people treat nature like this? There is only one earth. I seemed to hear the cry of Mother Earth, and I was still thinking about it until the evening.

After a while, I finally fell asleep. I had a dream that the trees around me were lush and the air was fresh and sweet. The next morning, I blinked my flexible eyes, and then I realized that I had a wonderful dream.

Dear friends, let's all protect the environment and continue to create beautiful homes! I believe my dream will come true. There is only one earth. Let's make the earth green!

There is only one earth in 400 words, 12. In the Chinese class this afternoon, we learned the text "There is only one earth". I benefited a lot from reading this text.

The text introduces the relevant knowledge of the earth from the perspective of human survival, which shows that there is only one earth for human survival and the significance of human protection of the earth's ecological environment.

By reading the text, I know that the earth is like a crystal ball, covered with a blue tulle coat. The earth, the mother of mankind and the cradle of life, is beautiful, spectacular and amiable.

The earth is so lovely, but it is also easy to destroy. We should protect it well. However, human beings ignore the surrounding environment too much. Solid waste produced in the process of human production and life is called waste. Such as industrial waste residue, feces, garbage, various plastic bags, beverage bottles, boxes, cans and so on. Pesticides and fertilizers are adsorbed by soil particles and accumulated in the soil as waste for a long time. There are many harmful components in garbage. If it is not handled properly and discharged everywhere, it will easily pollute farmland, water source and environment, further pollute crops and poison creatures such as birds and aquatic products.

Therefore, we must take care of the surrounding environment. You do well, I do well, and everyone will do well.

Then, in order to prevent waste pollution, the factory is required to do a good job in comprehensive management, turn waste into treasure, and not dump waste residue indiscriminately; Learn the common sense of removing pesticide residues in vegetables to prevent food poisoning; No littering or dumping.

In this way, our earth will be more beautiful. The earth has given us everything beautiful, so we should work together to protect the earth!

The earth is the only home for mankind. We should return the sky to blue, the sun to red, the earth to green and the earth to colorful!

There is only one earth in 400 words. A great man once said, "We should not be too intoxicated with our victory over nature. Every time such a victory, nature will retaliate against us. " This is also a fact. The sandstorm raging in northern China is the loss of a good natural environment and the punishment of nature for us.

There are also many such examples in the book "Advocating Civilization of Scientific Communication" that we read. There is an ancient famous city-Loulan on the famous Silk Road. In the 7th century, because people destroyed the natural ecology, Lop Nur, on which Loulan people depended, dried up, and Loulan gradually disappeared from the map. In many cities of our country, "acid rain" has appeared due to air pollution, and in rural areas, large-scale crop diseases have appeared due to global warming, as well as many incurable diseases of human beings, and so on. Isn't it all nature's "revenge" on us?

I am an excellent young pioneer. I want to tell people around us that we should take care of everything around us. We should take an active part in afforestation activities and plant beautiful flowers and trees in every corner of the motherland. We should also strictly abide by civic morality, do not litter or spit everywhere, and cherish our good living environment now.

There is only one earth for mankind. If we don't protect the environment and the earth, the earth will die one day. Students, let's all take action and join the ranks of protecting the environment, nature and mother earth from now on. I believe that through our unremitting efforts, we will have a beautiful landscape, white clouds and blue sky of the earth home.

Write a 400-word composition with only one earth 14. Today is Sunday. Early in the morning, my mother and I are going to the hospital by car to see our eyes. When we arrived at the bus stop, we saw a sea of people and it was crowded.

"coming"! "coming"! I don't know who shouted. As soon as I saw it, a car really came. Before the bus stopped, people swarmed. Suddenly, the crying of the child was mixed with the shouts of the adults. The people in the car shouted: "Don't get on, there is no place to squeeze! The people under the car shouted "Let's go up" desperately! The driver and conductor watched the uncompromising scene helplessly. This is, my mother and I can't help but squeeze into the car. I'm too young to breathe. Mom pushed hard at the back and finally got on the bus. The car started before I could stand firm. Suddenly, an aunt holding a baby behind me shouted, "My baby hasn't squeezed in yet! "! But the car is full of people. Can the driver hear his voice? The car is still moving forward. I don't know why the car drove slower and slower, and finally put out the fire before reaching a parking spot. The driver said, "There are too many people in the car to move. Please get off. "The children cried, the adults shouted, and they hugged each other. With a click, the door was crushed, but people were still pushing down.

I looked at this scene and sighed deeply from my heart: don't squeeze! Now the population of the whole world is soaring. If the population is not controlled, one day, the earth will be squeezed like a car. You know, there is only one earth!

There is only one earth. 400 words 15 in order to survive on another planet, human beings destroy our mother earth and abuse chemicals without restraint.

After reading There is Only One Earth, I have the impression that our activity space is limited and our natural resources are limited, and all natural resources are non-renewable. And humans don't want to destroy our mother earth and emigrate to other planets to survive. Even if there is a planet where human beings can live, how can few people go? We should cherish resources and protect the environment. We can start with some small things around us, such as: try not to use disposable goods; Implement garbage sorting; Pay attention to saving water and electricity; You can't turn on this light and TV for a long time when no one is at home; Natural resources are limited, and these seemingly trivial things in life will bring unimaginable consequences to mankind; We should protect our mother earth and not abuse resources; The water resources, forest resources, biological resources and atmospheric resources needed by human life could have been regenerated and contributed to human beings for a long time. However, due to the destruction of natural resources and the indiscriminate abuse of chemicals by human beings, it not only cannot be regenerated, but also triggered a series of ecological disasters, which brought serious harm to human beings.

Save our mother earth! Our mother is so cute, and at the same time, she is too young. Students' feelings are easily broken after reading it. Therefore, if we want Mother Earth to better benefit our future generations, we must protect our Mother Earth.
