What should I do to pollute the environment and how to write a composition?

1. How do primary school students write the composition of polluted environment

You can write what environment is polluted in your place and how, and then you can write whatever you think! You can also use the method of comparison. For example, there is a river that used to be very clean, but now it is polluted by people. Or you can write that there is rubbish on the road and sidewalk, etc.

There are many pollutants that pollute the environment around us, such as a large number of domestic wastes, plastic bags (also known as white garbage), disposable wooden chopsticks, disposable lunch boxes, and peel scraps. There is no doubt that pollutants do great harm to the environment. For example, the rotting carcasses of animals will affect environmental sanitation and breed bacteria. Disposable wooden chopsticks that restaurants and restaurants think are very sanitary are thrown away after use, which affects the city appearance and destroys the environment.

A drop of water can reflect the brilliance of the sun, and a green leaf can show the vitality of the earth ... There must have been something similar around each of us: when the curtain of the morning has not been opened, the cleaners have been cleaning it nervously and quickly. Originally, it was a clean and spotless street, but it was smeared with a black spot because a person littered casually! Going to the bathroom is a very common thing, but some people regard water as small and infinite, let it run away in vain, and make it appeal to mankind! In a public place, for example, in a flowing street, one person spits gum everywhere, and you may pass by casually, but the sun and the moon accumulate, and the street becomes a sika deer, no, it should be said that it is a spot on a zebra.

Cherishing resources means cherishing the present, cherishing the future and protecting the environment, which means defending the earth and protecting this peaceful and warm world.

listen! The faucet appealed to human beings: human beings, I don't ask for anything in return, just ask you to protect our limited resources and protect the earth with more than 1.3 billion people! In summer, I offer you cool and sweet water, but you do. . But. . Whoops!

Did you hear the call from the tap? How? Still hesitating? If "destroying" this demon has controlled your behavior, you should try to overcome it; If it is a fierce tiger, let's be Wu Song and knock it down; If it is a hard stone, let's be climbers and step on it.

come on! Humans, let's take action. Let's build a green base, and one more bird will fly to the embrace of nature. Cherishing resources is our common goal! On environmental protection, perhaps, if you stand in front of the window with your chin propped up, a series of question marks will pop up from your heart: What is environmental protection? I will give a rough explanation of the above questions: environmental protection, the extension of the word means recycling, while the original meaning refers to a way to protect the earth. Why do you want environmental protection? Because if you want to make the earth's resources continuously, you must use practical actions to prove that protection is protecting the earth now. Then, this small area of China will face a bright future! 2. How to write an essay about environmental pollution < P > Since mankind came to this world, it has been facing serious environmental problems. However, some people are facing such serious environmental pollution, but they have not realized that the signs of harm have come.

There are quite a lot of "white environmental pollution" on the earth where human beings live. For example, people go shopping in shopping malls, vegetable markets, etc., and all of them are packed in white plastic bags. Said it was because the white plastic bag was hygienic. But people throw it on the ground after using it, regardless of how much pollution it will bring.

There is also air pollution. Many rich bosses drive cars around. To some people, this is a sign of wealth. However, in the eyes of people who understand the great harm of this pollution, it is an uncivilized performance. These people make the whole city a mess, but they don't think they are destroying the environment.

in rural areas, with flowers and trees, the air is certainly good, and the environmental pollution will be reduced accordingly. But people don't know how to protect, but to destroy. For example, people cut down trees indiscriminately, leaving a mountain full of air and vitality scarred and lifeless. This has caused serious environmental problems, as well as swamps everywhere in the river.

With so many environmental problems facing mankind, how can we be indifferent? In order to prevent human beings from being threatened by environmental pollution, we should issue the call of "protecting the environment, starting with me" and "caring for every grass and tree is caring for human survival". Let's work together to "protect the environment"! 3. How to write a composition about destroying and polluting the environment (with concrete examples)

It's cloudy, with no smell of morning at all, and the calm beach is somewhat unusual. After a while, the light rain began to fall, which made the strange things on the beach more dazzling and turned the beautiful sea like a pure girl into an ugly old woman.

"Mom, look, what are the things on the beach?" Fish asked his mother curiously. Mother sighed sadly and said, "Hey, this is rubbish." The little fish asked, "So where did they come from? How can it be on the beach? " "This is all caused by human beings. They threw all the garbage into the sea, and these garbage rushed to the shore with the tide, which is like this." "Why do humans do this? Aren't they all children of Mother Earth? " Mother Fish said sadly, "Who says they are not the children of Mother Earth? But they are selfish. They throw all the rubbish into the sea for convenience. They think there is nothing wrong with this, but they will know later. " "oh? What will happen in the future? " "Humans rely on water, plants on the ground and marine animals to survive, but now there are fewer and fewer forests and places where food can be grown, replaced by deserts; Fresh water is wasted by human beings without restraint; Garbage contains toxic substances. If human beings continue to dump garbage into the sea, the creatures in the sea will be poisoned in the near future, and then human beings will not be able to survive ... Mother Earth's "green sweater" has now become a "yellow sweater", and her blue "eyes" are no longer shiny, leaving only chapped wrinkles ... "Mother Fish talked and cried. The little fish is also very sad. It looks at the sky and it is raining harder. "Mother Earth, are you crying? Although I am still young, I will try my best to encourage people not to ruin your appearance! "

The little fish asks his mother again, "Mom, isn't this rubbish useless?" "Of course not, some of them are more decorative and can be used for hand-making; Those glasses, waste paper, scrap iron, waste plastics and waste wood can be recycled. Non-recyclable garbage such as peels and rotten food contains more toxic substances and should be sent to the garbage disposal station for proper treatment. "

"I see!" Little fish shouted happily: "As long as everyone and every creature contribute a little, Mother Earth will always be the most beautiful mother!" "

At this moment, the rain stopped and a beautiful rainbow appeared in the sky, which is the most beautiful smile of Mother Earth! 4. How to write a composition on environmental pollution 3 words Grade 3

Environmental pollution

There are several dense forests, and there is a clear river between the forests, just like a blue ribbon.

However, gradually, the surrounding forests are cut down, and the original clear water in the river has disappeared, but it has become a stinking ditch. This is all because of the ruthless destruction of human beings! The swallow said to the little fish, "Human beings are so hateful that they not only make Mother Earth riddled with holes, but also destroy the home on which we live!"! "The little fish said: Yes, because of human beings, the water quality is getting worse and worse now, and I can't live any longer. Also because of the exhaust emissions from human factories, I can never see the blue sky again! "

When I saw this scene, I clenched my fist and felt sad and angry. I thought: Do those people have conscience? Please cherish the earth! 5. How to write an essay on protecting the environment

The first article is that 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 should 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 Geping, an environmental scientist, once said, "Only change can save the fate of mankind, and only change can make our future generations survive." The "change" in it means environmental protection.

That's right, so nowadays many people are holding slogans and shouting empty slogans in the street, but they haven't seen much action. Will pollution get better in this way? No! Look, the rivers in our city are black and smelly; Cars in long queues emit a lot of exhaust gas; A piece of green land becomes a "stone forest"; The crisp birdsong disappeared without a trace.

If this continues, China will continue to be short of water resources, the air will become more and more turbid, and 1% of bird species will disappear in this century. The above things, we humans are the culprit! Everyone knows that trees can absorb carbon dioxide, emit oxygen and purify the air, which is a necessary condition for our human survival.

However, some people cut down trees indiscriminately for money, resulting in excessive soil erosion, serious damage to the vegetation on the earth, desertification of oases and cities, and threats to our human survival. As for the disposable chopsticks we usually use, it takes tens of acres of forest every day. In the eyes of those people, trees seem to have no value except for furniture and building materials.

Is there anyone who doesn't understand what trees mean to us? Our living area is already very small. If we continue like this, we may even lose our only land. In addition, our mother river, the Yellow 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 the schemes to control the pollution of the Yellow River in an attempt to improve the water quality of the Yellow River. But without our participation, the Yellow River, the cradle of our life, will go to exhaustion and death.

If we destroy the environment without restraint again, nature will punish us. Those catastrophic floods claimed the lives of countless people, and due to the greenhouse effect, the glaciers in the Antarctic and Arctic melted, causing the water level to rise, and seawater flooded the coastal areas, resulting in heavy economic losses.

Isn't this the best proof? Guangning, my hometown, relies on bamboo sea eco-tourism to develop its economy. Nowadays, the environment of some bamboo forests is in a terrible state, which makes people complain. Zhuhai eco-tourism is the root of our development in Guangning. If the root is destroyed, how can we grow lush branches and leaves and open beautiful flowers? Let's be kind to human beings and nature! I wonder if you have read the article "1 things you can do to protect the environment".

actually, there are many things we can do. 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 small environmental protection guardian, using every green anniversary to promote environmental awareness, so that the green hills are always there, the green water is always flowing, and the soil is always fragrant ... These are all things that 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 warning bell has rung.

let's join the ranks of environmental protection in order to create a bright future where man and nature live in harmony, so that man and nature can multiply endlessly. Looking at it, there are only uneven land, and large tracts of forests have been cut down and become woodwork in people's lives. People only make groups of animals homeless and rush to other places for their own self-interest.

this is not a false fantasy, it is a bloody fact. Once upon a time, a large number of animals and plants in the world were extinct, and many animals and plants were on the verge of extinction. Why? This is all because human beings cut trees indiscriminately and destroyed the ecological environment, which is the fundamental reason.

Land resource is one of the three major geological resources (mineral resources, water resources and land resources), and it is the most basic resource and labor object of human production activities. The utilization of land by human beings reflects the development of human civilization, but it also causes direct damage to land resources, which is mainly manifested in soil erosion, land desertification, secondary salinization of land and soil pollution caused by unreasonable cultivation, among which water and soil loss is particularly serious, which is another serious crisis facing the world today.

It is estimated that the topsoil loss of cultivated land in the world is about 23 billion tons/year. Some people think that acid rain is a silent crisis, and it is the most serious environmental threat that has ever hit us, and it is an invisible enemy.

this is not alarmist talk. With the increase of industrialization and energy consumption, acid emissions are also increasing. They enter the air and form acid rain after a series of actions.

Although red tide has existed since ancient times, with the rapid development of industrial and agricultural production, water pollution is getting worse and worse. Since it was first reported in China in 1933, there were 194 large-scale red tides in 1994, of which there were only four before the 196s and 157 after 199.

petroleum pollution is quite harmful to water quality and aquatic organisms. The oil floating on the water surface can quickly spread and form an oil film, which prevents the water surface from contacting with the air and reduces the dissolved oxygen in the water.

Oils contain polycyclic aromatic hydrocarbons, which can be enriched by aquatic organisms and endanger human health. Sulfur dioxide is mainly produced by burning sulfur-containing substances such as coal and fuel oil, and secondly from nature, such as volcanic eruption and forest fire.

Sulfur dioxide has strong toxicity to human conjunctiva and upper respiratory mucosa, which can damage the respirator tube and cause bronchitis, pneumonia and even pulmonary edema and respiratory paralysis. The mortality rate of elderly or chronic patients exposed to sulfur dioxide with a short-term concentration of .5 mg/m3 is increased, and the concentration is higher than .25 mg/m3, which can worsen the condition of patients with respiratory diseases.

People who have been exposed to air with a concentration of .1mg/m3 for a long time have more respiratory diseases. In addition, sulfur dioxide is easy to cause corrosion, peeling, fading and damage to metal materials, building construction, cotton spinning and chemical fiber fabrics, leather paper and other products.

It can also make the leaves of plants turn yellow or even die. Protecting the environment is everyone's responsibility.

article iii insurance. 6. composition on environmental pollution

article 1: people always think that the sea, land and air on the earth are endless, so they never worry about sending tens of millions of tons of waste gas into the sky and dumping hundreds of millions of tons of garbage into the ocean.

Everyone thinks that the world is so big. What is this waste? We are wrong. In fact, although the earth is big, creatures can only live in the range of 8 kilometers above sea level to 11 kilometers under the sea, and 95% of the creatures can only live in the range of about 3 kilometers in the middle. People have wantonly polluted this limited living environment from three aspects. Marine pollution: mainly crude oil leaked from oil tankers and oil wells, pesticides used in farmland and
