The environment has changed, and the composition is 500 words

In the usual study, work and life, many people have had the experience of writing compositions and are familiar with them. The composition must focus on the theme and elaborate on the same theme. No rambling, lax theme or even no theme. How to write a composition to avoid stepping on thunder? The following is my 500-word composition in the finishing environment for reference only. Let's have a look.

The environment has changed by 500 words 1 It's said by adults that Huaihua is a city pulled out by train, and the Hunan-Guizhou line and the Liu Zhi line meet here. In the past 10 years, the development of Huaihua has undergone tremendous changes. There are many high-rise buildings, and buildings with more than 30 floors can be seen everywhere, such as BBK Department Store Plaza, Huatian Hotel and Luban Yayuan. There is a lot of traffic on the road, and BMW and Mercedes-Benz cars that can only be seen on TV before can be seen everywhere, but the pollution in Huaihua is getting more and more serious.

The first reason is that cars are barking constantly everywhere, and all kinds of advertisements pop up in the streets and alleys, which are full of our ears and eyeballs, and at the same time cause serious noise pollution, which will seriously reduce our hearing in the long run.

Reason 2: Now that living conditions are better, there is more garbage at home, and the phenomenon of littering has also increased a lot. A casual glance reveals all kinds of rubbish everywhere. If you inhale too much polluted air, the chances of death will increase a lot.

Reason 3: The exhaust gas from automobiles contains carbon dioxide, which will destroy the structure of the atmosphere and increase the lead content in the air. When people inhale too much air with excessive lead content, it will lead to lead poisoning and cause various diseases.

Reason 4: Huaihua is now in an important position in the development of the western region. Real estate development is everywhere, and vehicles transporting muck are often overloaded, resulting in serious road damage. In addition, people's living conditions are getting better and better these days, there are more and more private cars, and traffic jams often occur in Huaihua city. The whole city is filled with dust and waste gas. It is often dusty in sunny days and muddy in rainy days.

It is everyone's responsibility to protect the environment, starting from me and starting from the details.

The environment has changed. I was born in Jinan Jigang New Village. My hometown is beautiful everywhere. In fact, my hometown was not beautiful before! In just a few years, the changes in my hometown are so great!

Jigang used to be like a small mountain village with a low bungalow. When it rains, the land in my hometown will become muddy. It's dusty on a sunny day, the road is rugged, and the trees on both sides are yellow. There is rubbish everywhere; Weeds are everywhere; There are wasteland everywhere.

The campus is small and broken, the classroom is dark and dark, and there is nothing on campus except teachers! There is not a flower anywhere. Behind the campus is a wasteland. Baoshan is bare and there are no trees.

Through people's efforts, my hometown has been created into a beautiful place with tall buildings, trees and flowers in full bloom.

Nowadays, the high-rise buildings in my hometown stand tall, and the bungalows in the past have also become high-rise buildings, and flowers are blooming everywhere in my hometown; There are tall buildings everywhere; When the director is full of green trees, my hometown will build a veritable green garden!

The campus has become a place with sports equipment, tall buildings, playgrounds, flowers and trees!

Pavilions and pavilions can be seen everywhere on Baoshan, as well as artificial lakes and zoos ... In the morning, many people are humming a tune while climbing mountains!

There is a musical fountain in the central square. In the evening, when people relax and have fun, they can watch the fountain while listening to music! There is also a big screen in the square. When people come out to play, they can watch the news while playing! There is a tall building in the square with four big characters flashing on it. When people don't like cooking, they can have dinner together. How convenient the changes in my hometown have brought to people!

I want to be a useful talent and make my hometown more perfect!

The environment has changed. Science and technology have become more and more developed with the wisdom of human beings, and traffic life has become more convenient. We don't need to walk into the street anymore. Where it used to take a few days to get there, now it only takes a few hours! But the waste gas used has also increased! Of course, the environment has deteriorated!

Flat roads have replaced steep mountain roads and muddy ancient roads. The children's playground replaced the straw pile. Today's businessmen have replaced farmers who used to work.

However, because of the increase in the number of cars, there are more exhaust gases, the environment is getting worse and worse, and the air is getting dirty. I don't know how many people will die because of the dirty air in the future.

The original leaky hut became a small house. Many people live a happy life. The original green forest turned into a silent desert. Then who knows that we live a happy and beautiful life on the surface, in fact, this is only temporary, and the real danger is slowly approaching us.

In the past, the earth with many animals and plants has become a polluted world with endangered organisms. Although we are not extinct, every life is equal. Cutting down a tree is equivalent to hurting a life. So we should plant trees together to restore the previous environment.

Some people are protecting the environment, but they are still being destroyed, so we should improve the environment. Our environment has changed, but only for the worse. We should do better! The earth belongs to everyone, and the environment belongs to everyone. Why destroy your home, just to live a happier life? Some people still call nature tasteless, but they don't know that human beings have changed the environment and made it worse!

The environment has changed. In recent years, my hometown has changed a lot. There are good and bad. There are few good ones and many bad ones. With the destruction of the environment, nature has given us severe punishment and almost destroyed our family.

In recent years, Binan River has become a stinking ditch and an "ink bottle". The original fish and shrimp are gone, and the original white face is gone. Fish and shrimp have been replaced by mineral water bottles, broken shoes, milk boxes, banana skins and so on. The clear face has been replaced by a muddy crying face, and the weeping willow beside it has been replaced by a bare trunk. Even the leaves of the tall yellow-horned tree downstairs have fallen by half.

Bi hot spring has lost its beauty, even the "hot spring" has become hollow, a large area of land has become the foundation of houses, and the green grass at the foot of the mountain has become a barren dam. The pond became a garbage dump, and half of the high hills were gone. It was burned by forest fire, and even the pipes flowing out of the spring water were almost out of water. ...

In the TV Tower Park, some mineral water bottles, disposable chopsticks, cans and apple peels are mixed in the grass ... The originally beautiful grassland will soon become a "garbage dump", wild flowers are smiling and a meadow is swaying in the wind. There are always people who don't care about public morality running around on the lawn. Deep footprints are printed on the lawn, and the ground is covered with wild flowers. ...

My hometown has really changed, both good and bad. I don't know how bad it is. Only excellent people have taken the first step of their dreams, ah! Why has my hometown become like this! Does hometown have to be like this? Ah! Why does my hometown become a garbage dump, a sewer and a disgusting city? The earth was beautiful at first, and so was here at first. Why is it disgusting here now? Protecting the environment means protecting yourself, and destroying the environment means leading yourself to extinction. Ah! What's hometown like? What is the government doing?

The environment has changed 500 words. 5 Long ago, there were no flowers on the earth, but flowers were everywhere. Animals live freely and the earth maintains ecological balance.

Since the emergence of human beings, the earth has begun to change ... it is no longer gentle and amiable, but now it has become rude and abnormal. What's going on here?

The environment in our city is getting better and better now, which is the credit of the whole society.

In the past, people always littered and destroyed the ecological environment. Rubbish such as peel crumbs and beverage bottles can be seen everywhere on the road, which causes passers-by to accidentally fall and increases the burden on sanitation workers. But now people's consciousness is strengthened, and everyone throws garbage in the trash can on the roadside.

At present, there is no phenomenon of indiscriminate felling of trees. People used to cut down trees to make furniture and toilet paper. Trees can absorb carbon dioxide and provide people with fresh air. If there were no trees, we wouldn't have fresh air, so we cut down the types of trees.

Air pollution was also very serious in the past. Exhaust gas from factories, kitchen smoke from every household and exhaust gas from cars all destroy the environment and are harmful to health. Fresh air will also be taken away by these waste gases, but now people don't emit a lot of waste gases. More and more people ride bicycles on the road, and the air in our city is getting better every day.

Disposable goods is harmful to the environment. For example, chopsticks and lunch boxes all contain toxic substances, which are harmful to human body. I hope everyone will not use these things.

Our living environment has changed a lot now, and we hope it will get better and better.

The environment has changed. My hometown is Longhui County, Hunan Province, where the trees are lush, the air is fresh and sweet, and the spring water is crystal clear. This is a good place to travel.

Now, let me show you how the trees in my hometown are. Grandpa said, "There were not many trees here before, but now they are flourishing." I asked strangely, "Why is this?" Grandpa said, "This is because in the past, every family had a sharp axe. Whoever wants to build a plow, a stool and a house will pick up an axe and cut down trees on the mountain. In this way, there are fewer and fewer trees on the hillside and more and more bare land, and he has been punished by nature. So, once, our village was almost washed away by the roaring flood. Later, the villagers in our village increased their awareness of environmental protection and decided to cut down trees if you want, but if you want to cut down trees, you can plant trees, so there are more and more trees in our village. You see, all the saplings in the back hill were planted by us only a few days ago. So the air in our village is also very fresh. "

Grandpa said that the air in our village is very fresh. How did this happen? According to grandpa, this is because there are few factories in our hometown. But there were several before, but the government reported that these factories were too polluted, so the government didn't allow them to open factories here. And not only that, because there are many trees in my hometown, can the environment in my hometown not be fresh?

Let's take a look at the water quality in my hometown. The spring water in front of the village is crystal clear, because there are few factories in my hometown. Now everyone's awareness of environmental protection has increased, and they don't throw garbage into the spring water, so the spring water in my hometown is crystal clear.

People in my hometown know how to care for and protect the environment, which makes the environment in my hometown better and better.

The environment has changed. 500 words 7 2 1 century human beings seem to have entered a relatively affluent society with all kinds of necessities. However, people's awareness of saving is getting weaker and weaker, and waste seems to be a matter of course.

Nowadays, it is very popular for rich people to eat in hotels. In order to save face, they immediately ordered a large table of dishes. Who can finish it? So the leftovers on the table are wasted. For another example, when some schools serve breakfast, they give each student a steamed bun, but ignorant students throw it into the trash can because they are not appetizing. Some people may think that a steamed bun is just a piece of cake. Is this really a trivial matter? Let's solve it together. China has a population of1300 million. If each person wastes/kloc-0 steamed bread every day, 365 days a year, 474.5 billion people will be wasted. If each steamed bread is12,474.5 billion steamed buns, there are 47.45 billion Jin. What an amazing number! How many farmers have to work to get so much food! On the other hand, if each of us saves a steamed bread every day, it is also a lot of wealth. At present, our country is not rich enough, and even some places suffer from natural disasters. People don't have enough to eat and don't wear warm clothes. Wouldn't it be meaningful if we could give them this wealth? In addition, a common phenomenon can be seen from throwing steamed bread, that is, the current young students' awareness of saving is very weak. For these people, no one will welcome them.

Saving, starting from me, starting from the side, starting from small things, can make our China richer.

The environment has changed. In the past, the phrase "we live in nature" always sounded ridiculous. Because when I think about this topic, I will think that my window is facing the construction site. The sound of electric drills and the knocking of metal materials from time to time sounds very harsh. Groups of bricks and stones were placed right under our window, covering the dusty seedlings, so the last bit of "nature" was drowned by blind urban construction.

Today, great changes have taken place in Xuzhou, the city where we live. Small saplings stand upright on the roadside, and the dust and garbage on the road are gone. People put all kinds of trash cans on them. On the lawn, there is always a sign to remind us to care for the environment.

Yunlong lake has also changed a lot. In spring, its beautiful scenery attracts people who walk side by side, so that you will never forget the wonderful color of spring. In summer, there are waves rolling on the clear lake from time to time, stroking the fish and shrimp in the lake, and the lotus flowers in the middle of the lake are in full bloom, which makes you admire. In autumn, a fallen leaf falls on the shore and becomes the feed for the mother tree. In winter, the cold wind blows hard and the lake freezes, but it doesn't make us feel a chill, but it makes us feel the warmth inside, because this kind of beauty is only in an instant.

One day, on my way to school, I don't know when a morning glory bloomed, and there were many small buds beside it. This morning glory saw the beautiful Xuzhou and told the news to another Xiaolei. Gradually, a little bud couldn't help it. It blossomed beautiful flowers. ...

The environment has changed. Now, our living conditions are getting higher and higher, but our awareness of environmental protection is getting worse and worse.

Everyone pays great attention to hygiene at school. How nice it is to pick up a scrap of paper, a peel and a waste bottle and can on the ground and sort them!

But outside the school, everyone has changed. What can't be eaten is thrown everywhere. When taking the bus, while eating snacks, throw out the packaging bag. What paper bowls, drink bottles, and melon seeds with peels? Throw it if you want. The bus passed by, leaving a garbage landscape.

Let's talk about our Yanhe Road Park again. There used to be trees and flowers here. Now, I smell a strange smell from a distance. Take a closer look, there are some garbage bags, convenient bowls and a lot of nameless garbage floating on the river. Why doesn't the river stink? What is even more unimaginable is that someone deliberately broke the chain on the railing by the river. How dangerous! The child is still shaking when walking, so pay more attention.

Parks along the Yangtze River are also good places for walking, but cows often graze there freely and defecate everywhere along the hillside along the river, attracting many flies and bedbugs. That's disgusting. Everyone was tired from walking and wanted to have a rest, but the four-legged stone bench on the roadside became three legs, and there was rubbish on the better stone bench. How do people sit?

There is still an imperfection, that is, some school advertisements are posted everywhere, and even telephone poles and sidewalks are painted with colorful paint, which looks unpleasant. These phenomena are called "urban psoriasis", who will treat them!

Walking casually in the street, you will see too many unsightly places, all of which are caused unconsciously by everyone. The Olympic Games is coming. If you don't pay attention to the environment, you will be teased by foreign friends.

Environmental protection depends on everyone. We must start from ourselves, and everyone should start to protect our home.

The environment has changed. 500 words 10 Time flies, time flies. In a blink of an eye, I have graduated from college. I really want to go home and see! It took me three days and three nights to reach my hometown Daqing, which I miss very much. Seeing some parents with gray sideburns, my eyes are moist.

On the way home, we saw great changes in our hometown! There are high-rise buildings everywhere, wide airport roads, beautiful traffic in century avenue, and trees everywhere ... I was dazzled all the way, but I didn't smell the automobile exhaust at all. I was surprised to ask my father, "Why can't I smell the car exhaust now?" Dad said: "Nowadays, cars are very environmentally friendly, and most of them burn fruit-flavored juice. Exhaust gas can not only pollute the environment, but also protect the environment and promote the growth of trees, so don't you see how lush our trees are? "

Walking, my eyes suddenly lit up. "Why is the red light square, the green light triangular and the yellow light round?" I asked my father in surprise. Dad smiled and said to me, "It's to solve the troubles of color-blind drivers." I suddenly realized. We came to Laoliming River, which is full of silt and stinks, but what caught my eye was a crystal clear river with many small fish playing in the water, which surprised me! Dad explained: "the quality of the whole people has improved and clean water has been invented." Just drop two drops into the water and the river will become crystal clear. " When we talk, we look at everything in our hometown. ...

My hometown, the charming Daqing, amazes me, but I firmly believe that my hometown will become more and more beautiful!

The environment has changed. The times are developing and the society is changing. Looking back carefully, the flowers and trees on the mountain were lush, and now, everything seems strange and different.

On the way home from school again, I noticed that there were only crowds and waves of cars in the street. The pungent car exhaust penetrated into my nostrils and directly occupied my heart. Looking up, it should be a clear and transparent sky, but now it is covered with a gray veil and the air is not as fresh as before. At this time, I suddenly found that there are more and more foggy weather in the city now.

"DuDu-DuDu-"Although it has been clearly stipulated that honking is not allowed in urban areas, some people are so unscrupulous. The City Symphony still rings noisily, as if it will never stop. I suppressed my unhappiness and sat on my mother's battery car and looked around. I'm almost home, and I'm caught in a traffic jam. I'm finally moving forward.

I don't know how long it took, the pedestrians and vehicles on the road became sparse, and the noise of the city gradually disappeared in my eyes. I have arrived home. My home is close to the mountain, and behind it is the forest. From time to time, there will be crisp and pleasant bird songs echoing in my ears. Let me have a feeling of returning to nature.

While enjoying the unique quietness and fragrance in the mountains, I am also thinking about this question: How many quiet places can be comparable to nature in this big city today? Maybe it's really not much. Now we think that rest is watching TV at home. I didn't know that the most beautiful scenery was in nature.

Recently, because of people's over-exploitation of resources, high-rise buildings stand on the fields, and the real green has become less and less. But fortunately, my home is right next to this mountain. Whenever I walk to my door, I always feel unspeakable joy in my heart. That feeling is like a clear mountain spring pouring down, washing the dust in my heart clean.

Perhaps only staying in this quiet place can make people feel calm.

The environment has changed by 500 words 12. Everything around us is changing every day, whether it is people or things. Of course, the environment is changing rapidly now. I find that some changes are taking place around me.

In the past, the mountains were green and the water was clear. As long as you walk out of the house, you can smell the very fresh air without any peculiar smell. But what about now? Because of the increase of motor vehicles, a lot of carbon dioxide is emitted, which makes the air not so fresh.

Everyone used to care about forests and trees, and the mountains were very green. Walking into the valley, it's like towering old trees and shady trees; It's cool. In the park, no one stepped on the lawn and no one littered. Nowadays, many people ignore the law and illegally cut down trees. The valleys and forests are not covered by green trees, but they are so hot that people sweat-the sun is scorching. Parks are not much better. When you enter the park, you will see many people sitting or walking on the lawn through the guardrail. Garbage can be seen everywhere on the ground, and no one sends it back to his home-trash can.

In the past, the water was very clear, reaching the bottom. This water has not been polluted by any chemical plant, even the small fish and shrimp at the bottom of the water can be seen clearly, and it is not dirty at all. Now, because more and more chemical plants are dumping sewage into the river, the river is no longer crystal clear and stinks. As a result, a large number of fish died.

I hope this change will not continue. How I hope everyone can take action to protect our living environment and build our home together! I hope it will be better, not worse, when the environment changes next time!

Since the reform and opening up, great changes have taken place in people's living standards and miraculous changes have taken place in my hometown. My hometown is Hexi Village, the hometown of Heishan County. A narrow winding river flows slowly south from the village.

Grandma said that we used to be very poor here, and all the villagers lived in shabby little mud houses. When it rains, there is a light rain at home. At that time, there were no factories and shops, and owning a bicycle of that year has become the goal pursued by people. At that time, people were wearing patched clothes. As the saying goes, "three years new, three years old, three years patch." Even the shoes are made by their own dexterous hands. Grandma also said that at that time, only the village Committee had a black and white TV set. In the evening, people go to the village early to form a big circle and watch TV. The phone is the same. Every household can only call the village Committee if there is anything, and then the village head will inform the households. Now earth-shaking changes have taken place in my hometown. The low, damp little earth houses are gone, and rows of spacious and bright Beijing are unfolding before your eyes. The flat country road is connected with the asphalt road leading to the county town not far away. Now, as long as you just walk into a house, there are all kinds of home appliances such as TV, washing machine, refrigerator, telephone and mobile phone. Many families have installed computers and air conditioners. There are more and more private cars in the past two years. These things bring great convenience and endless fun to people's lives. There are all kinds of goods in the supermarket. It's really a new year, a new atmosphere every year. In the future, my hometown will be more prosperous, beautiful and lovely. The change of hometown is inseparable from the prosperity of the motherland. Only when the motherland is rich and strong can our small family get better and better. We are the flowers and future of our motherland. We should study hard, grow up to be pillars, repay the motherland and make the motherland richer and stronger.

The environment has changed by 500 words 14 What a beautiful season summer is. My parents and I went to Martyrs Park again. I had a good time all the way. I remember playing in Martyrs Park before. Martyrs Park is beautiful and the air is fresh. The lake is very clear, and there are many layers of waves, which are very beautiful. Grass is green, like a green carpet. How tall and straight these trees are. They breathed a lot of fresh air for us. The road is clean and the roadside is full of colorful flowers. ...

We soon came to the Martyrs' Park and entered the Martyrs' Park, and the fresh air came to our faces. Green trees, colorful flowers, light green thick grass. The three of us rushed to the lake together, ready to row. Suddenly an unpleasant smell came straight at us. Why has the lake become so smelly? I took a closer look and found that people lost a lot of food and drinks, and there was a lot of garbage in the lake, so the lake became like this. My mother and I are a little dizzy, so we will row the boat to the center of the lake as soon as possible to feel more comfortable.

As soon as I rowed the boat ashore, I saw someone throwing rubbish on the ground, and several cleaners kept sweeping it. The dust on the ground flew upwards, so we had to run over with our noses covered. I am very angry: why don't those who litter throw their rubbish into the trash can? ! When we were ready to go back, I suddenly saw someone playing badminton, someone rolling and someone sleeping on a large lawn. I seem to hear the grass crying and shouting, "I live like you!" " "We had a good time today, but I want to shout loudly: Take care of our Martyrs Park! Take care of our environment!

The environment has changed by 500 words 15 In this colorful world, although technology has developed and life has become better and more comfortable, the ecological environment is deteriorating.

Look, the poisonous yellow smoke from the chemical plant is floating into the blue sky; You see, the sewage pipes lead directly to the river, and the clear river water has become turbid and smelly; Look, someone is cutting down forests, dense forests are decreasing and land desertification is increasing. Especially in busy farming, there are always many people setting fire to straw. At this time, the sky is always gray, and all kinds of smoke and dust are floating in the air. Get up in the morning and open the window to ventilate. I cough badly just after taking a few breaths.

According to my mother, the ecological environment in the past is very different from the present. Although the living conditions in the past were not good, the sky was blue, the water was green, the trees were lush, the fish swam in the stream, the birds sang in the branches, the grass danced in the wind, and the river water could be drunk directly. What a beautiful ecological environment! Now, human beings wantonly destroy the ecological environment for their own interests. Take the river in front of my house as an example. When digging, the water was so clear that even the stones and small fish and shrimp at the bottom of the river could be seen clearly, but the good times did not last long. Some people dump garbage into the river in order to walk less, and the domestic wastewater and industrial wastewater in the upper reaches soon polluted the river. Today, the river in front of my house is black and blue.

Now the environment is really getting worse every day! Debris flow, landslides, acid rain and other natural disasters often occur, destroying our beautiful home. We should cherish our living environment and hope that everyone will contribute to beautifying the environment and the future will be better.
