article 1: air pollution

recently, I investigated the air quality in the health school community where my family lives. After this investigation, I found that the air in the community has been seriously polluted. The main pollution sources are: the fumes emitted by restaurants next to the community; Exhaust gas emitted by passing vehicles; Someone is burning garbage in the back hill of Mei Feng Temple nearby, and it is full of smoke. It is these harmful gases that pollute the original fresh air. These air polluted by harmful gases will have a negative impact on human health, and will also have a very bad impact on the growth of surrounding flowers and trees.

everyone has his own rules to protect the environment. In order to prevent the air in my hometown from being polluted, I think all of us can do a lot of things to contribute to prevent the air in my hometown from being polluted. First, you can write a proposal to the restaurant next to the community, suggesting that the restaurant treat the lampblack and then discharge it into the air. It is also necessary to improve the automobile engine and reduce the emission of exhaust gas; Second, everyone should take good care of flowers and trees, because flowers and trees are oxygen factories and air filters, which can effectively purify the air; Third, we should pay attention to environmental sanitation, no littering, no spitting, etc.

ah! We have developed a good habit of protecting the environment and a good habit of civilized hygiene since childhood. Let's mobilize Let our living environment be better! Chapter 2: Reducing air pollution

Today, the earth is not clear, the grass is not green, the flowers are not red, and the sky is not blue. However, everything that happened here is "attributed" to us human beings. Reducing air pollution, noise pollution and food pollution has become an urgent pursuit of mankind. However, today we will talk about traffic pollution in air pollution.

In today's society, more and more families have their own cars, and the traffic has become crowded. Traffic jams and car rear-end collisions occur frequently, which leads to many traffic accidents. However, the increase of cars also means the increase of tail gas and the serious pollution of the atmosphere.

Once, I saw a story in an essay:

There was an old woman with a rich family. She had enough money to take a private car every day, so she didn't have to be crowded with so many people on the bus and was in danger of being knocked down, but she still insisted on taking the bus every day. The driver was very surprised and asked her, "Why do you squeeze the bus every day?"? You have so much money. " She smiled and said, "The car pollution is too serious, and there are too many exhaust emissions." Suddenly, the people in the car were shocked and cast admiring eyes on the grandmother.

At this moment, we all understand the good intentions of grandma. She reduced the air pollution with her own actions. She is an ordinary and great person. If each of us can start from ourselves like grandma, then we will get not only our own future, but also the future of our children and the future of the earth. Driving less, taking more buses and cycling more have become effective ways to reduce air pollution.

Effective use of bicycles and electric vehicles can also reduce air pollution. However, the benefits of cycling go far beyond this. It can also help people exercise. Imagine how harmful it would be if 111 people had their own private cars. Imagine again that if these 111 people change to riding bicycles and electric cars, it will benefit all mankind.

protecting the environment starts from you and me, from traffic, from taking a bus and riding a bike once. Maybe it's just a small attempt that will change a lot. Maybe after a few years, our water will be cleaner, our grass will be greener, our flowers will be redder and our sky will be bluer ... Chapter III: Air Pollution Composition < P > The earth, the cradle of life, has been seriously damaged by human beings. There is no water to drink in many places due to environmental damage, but the air is more polluted. Air is the most important thing for human beings, so I want to make the air fresher.

The original air near my home is very fresh. I get up early every morning and feel happy when I breathe the fresh air. However, in recent years, smelly black smoke suddenly appeared there, causing many people to cough all day. What I have never understood is why the air is not fresh as soon as the smoke from the factory is discharged. I probably know the reason by looking up the information. It turns out that the smoke emitted by factories contains toxic substances, which spread to many places with the direction of air transmission, and some substances have destroyed the ozone layer. According to the data, the ozone layer is destroyed, and people will not be able to breathe fresh air soon. After reading these materials, I can't help but feel a little scared. God, it's terrible! I want to appeal to the world: people, wake up! People in charge of those factories, don't destroy the air so casually in order to earn more money. Mother earth can't stand any more torture. Are you doing this right for her? Although I am only a pupil, I clearly know the importance of air to human beings. You will not be worse than a pupil, will you?

air, the umbrella of the city; Air, human life; Air is the treasure of the world. Air, I want to make you fresher! Chapter 4: air pollution

On Saturday morning, my parents and I rode bicycles to feel the air quality in Puyang. Although the weather is cold, I don't feel cold, because I want to be a small air investigator.

We talked and laughed all the way. When we reached the west section of huanghe road, an unpleasant smell came to our nostrils. I asked my father, "Dad, what is this smell? It stinks." Dad said to us: "This is the chemical plant in our city, and the smell of waste gas produced by chemical plants."

My parents took me to Majia River again, and saw that the river was black and had a bad smell. I asked my father, Why? Dad told me: this is because the sewage from chemical plants and domestic wastewater are discharged into rivers.

The air pollution is too serious now. The waste gas produced by chemical plants and household wastewater are directly discharged into the air and rivers without treatment. The number of motor vehicles such as automobiles and motorcycles is increasing rapidly, and the exhaust emissions are increasing. This has caused serious air pollution.

In order to alleviate air pollution, please start from the small things around you, don't litter, don't burn fires in the wild, and try not to use cars with high exhaust emissions ... I believe that with your support, the harm caused by air pollution will definitely disappear! Chapter 5: Air pollution is harmful

My hometown, Dalian, is a beautiful city. According to my father, Dalian used to be a city with beautiful environment and fresh air. The air was filled with the smell of the ocean. After the rain in summer, you can often see beautiful rainbows hanging on the horizon like colorful bridges. I have seen many photos of my father's childhood life at home. In the background of the photos, I saw that the sky in Wan Li was cloudless, and there were few motor vehicles of all kinds on the road. At that time, people's means of transportation were mainly buses, and the environment was really much better than now.

Now there are more cars in my hometown, and thousands of cars are driving on the road every day. The exhaust emitted by these cars not only damages the environment, but also harms people's health. I heard on the radio that the exhaust gas emitted by cars has warmed our city, and these gases are suspended over the city and it is difficult to dissipate. There are still a lot of carbon monoxide and carbon dioxide in the exhaust gas of cars, which are harmful to human body. If people inhale them, they will cause many diseases in the lungs. No wonder when I go to school every morning, the sky is always gray. It is difficult to see the rising sun in the morning. There is no rainbow in the sky after the rain, and the deep blue sky disappears. Even the chirping birds don't want to come to such a place. Only in children's songs can there be a scene of "The sun shines in the sky, flowers smile at me and birds say …".

Do you know that she is crying in Dalian? She is crying that people have hurt her and destroyed her, making her beautiful face so ugly. I suggest that families with cars should reduce the use of vehicles and try to walk or take buses, so as to make our city air fresher.

let's take action! Beautify the environment, starting from me, starting from now! Chapter 6: Drive away air pollution

Urban pollution is a kind of air pollution that is very harmful to human body. The main reason for this pollution is the rapid expansion of urban population and so on.

yesterday, I saw a news report on the news broadcast that shocked me. It was about urban pollution. It says that the ten cities with the worst air pollution in January were Xingtai, Shijiazhuang, Baoding, Handan, Langfang, Hengshui, Jinan, Tangshan, Beijing and Zhengzhou. When I saw this, I froze. Zhengzhou is the capital of Henan. In my impression, her air quality is still relatively good, but how can it be so disappointing this time? Such a disgrace to us Henan people?

I remember that in the past, Zhengzhou was full of flowers and birds in spring. In summer, trees are shaded and the sun is like fire; The orchard in autumn is fruitful and fragrant for thousands of miles; In winter, it is covered with snow and white. Such a beautiful home will even enter the "honor list"!

looking down, the ten cities with the best urban air in January are Haikou, Fuzhou, Zhoushan, Xiamen, Huizhou, Zhaoqing, Shenzhen, Kunming, Lhasa and Zhuhai. Why can other cities protect air quality so well, but we can't? When I went to Zhengzhou before, as long as I walked to a vegetable market, the corners were full of white plastic bags. Are these plastic bags one of the sources of air pollution? Are the chemicals used one of the main sources of air pollution ...

Let's work together with Qi Xin to drive the monster of urban air pollution out of our charming home!
