In our daily study, work or life, we always have to touch or use writing. Writing is a verbal activity that people express their ideas in written form. I believe many people will find it difficult to write the composition. The following is a 411-word composition of the environmental investigation report carefully compiled by me for reference only. Let's have a look. Environmental investigation report composition 411 words 1

With the progress of science and technology of the times, many people have devoted themselves to the life of studying science and technology, but these people don't know how to protect the environment and throw peels and scraps of paper everywhere! In front of our school, many people, including our classmates, throw peels on the wasteland in front of us because they are not very particular about it and don't understand knowledge! Let me give you a picture of the land that is now unbearable: the last time I went fishing with Luo Heng and other students, I just stepped into that land, and a group of mosquitoes came at us crazily, and a burst of Hong Kong bean jelly beriberi came at us! We covered our noses and reluctantly walked to the stream to get water.

that water is even more amazing! Black colors make my face black, and I want to see none of us.

After receiving the water, I opened my eyes and saw the dirty garbage beside the stream: plastic belts, plastic bottles and other discarded things! Do you know what plastic belts can do? It can harvest 1 mu of land every year! If this continues, the beautiful earth will eventually be destroyed like Mars! ! ! Who did this? Residents living nearby, of course! As long as they have garbage, they dump it in here. When the workers see it, they set fire to burn all the garbage here! Severe smog has destroyed the ozone layer that protects our planet. Without it, human beings will be exposed to 111% ultraviolet rays from the sun! If we protect our earth now, the earth can live longer and longer! !

My family lives in Taishan District, where the air is fresh and sweet and the trees are lush, including camphor tree, acacia tree, magnolia tree and willow tree. In summer, the trees are lush, which is a good place to enjoy the cool. The community is full of clover and the lawn is full of thorn grass, which is very beautiful.

The roads in our community are clean and the environment is beautiful now, but when we first moved in, we were disappointed: the environment was not good, there was no green belt, there were few trees, and the roads were dirty and uneven; Some people plant trees and raise chickens and ducks in the open space, and put their cars wherever they want; The air pollution is so great that when the window is opened, it smells bad and the road is dusty.

why has our community changed so much? Through my investigation and visit, I finally found the reasons: First, the community has vigorously strengthened the greening work, planting trees and pruning trees regularly every year, so that the greening area has been increasing. Second, the management of the community has been strengthened, people's awareness of environmental protection has been enhanced, and the behavior of destroying trees has been greatly reduced. Third, sanitation workers have increased the frequency of cleaning, and the sanitation situation has been greatly improved.

By looking up the data, it is found that trees are of great help to the environment. First, trees can absorb dust and carbon dioxide and purify the air. Second, trees can fix soil to prevent soil erosion; third, trees can reduce noise and be beneficial to health; Fourth, trees can adjust the climate and increase precipitation ...

It turns out that trees have so many benefits for us, so we must protect them and make our green home more and more beautiful! Environmental investigation report composition 411 words 3

The other world is a paradise with a beautiful environment.

There, the sky in spring is as clear and blue as the sea water, and there are a few white clouds floating. There are many trees planted there, everywhere is lush, the water in the pond is crystal clear, there is not a scrap of paper, and there is a lunch box. The ground is cleaner than home, and almost everyone has managed not to throw scraps of paper.

There, in summer, unlike us in China, people go to a barbecue shop to eat meat products such as chicken, fish and beef every day. They only have cabbage, fruit and other items on the street. They never eat meat products. It's cool in that world, and everyone is extremely comfortable.

There, in autumn, leaves fall slowly in a whirl, and people consciously take vacuum cleaners and brooms to sweep the streets, oh! You must be surprised to ask, why do they take a vacuum cleaner to sweep the floor? Of course, it is to suck up dust to protect the environment.

It's very cold there in winter. Although it's very cold, they feel the air there is particularly fresh.

oh, you must really want to go there after listening to my introduction! But that world may be abroad, or even farther away. But as long as we pay attention to the environment and everyone protects it, maybe the environment of another world is in front of our eyes in China.

With the progress of science and technology and the development of economy, human beings have done great harm to the exploitation and utilization of the earth's resources: sharp decline of forests, desertification of land, excessive exploitation of coal, oil, natural gas and other mineral resources, mass extinction of species ... The earth is scarred and crying.

A few days ago, the water from the upstream rushed into the Qianyoufang River. The water in the river gave off a bad smell, which we can smell every time we go to school, and a large number of fish died in the river. In addition, some industries are called "three wastes", "waste water", "waste residue" and "waste water", which has caused great damage to our environment.

In the face of these things that damage the environment, our government has also taken preventive measures, such as establishing nature reserves, strengthening the protection of natural forests and the construction of artificial forests, and strengthening international cooperation. Laws and regulations have also been formulated, such as the Environmental Protection Law, the Marine Environmental Protection Law and the Water Pollution Prevention Law. The United Nations has also established environmental protection organizations, such as the United Nations Fund for Nature, Friends of the Earth and Greenpeace.

I believe that in the next 21 years, the earth will be full of vitality and environmental protection work will be better. China will become richer and stronger ... environmental investigation report composition 411 words 5

White pollution is a unique environmental pollution in China's cities. A large number of discarded plastic products can be seen everywhere in various public places. They come from nature and are made by human beings, but they are not easily absorbed by nature when they are finally attributed to nature, thus affecting the ecological environment of nature. From the perspective of saving resources, plastic products should be recycled as much as possible because the main source is exhausted petroleum resources, but the production cost of recycling at this stage is much higher than the direct production cost, which is difficult to do under the current market economy conditions.

in the face of the increasingly serious problem of white pollution, people hope to find a plastic substitute that can replace the existing plastic properties without causing white pollution. Degradable plastics emerge as the times require. This new type of functional plastic is characterized by its obvious changes in its chemical structure under certain environmental conditions, resulting in some performance losses and appearance changes, which is harmless or less harmful to the natural environment.

For example, starch-filled plastics, firstly, the starch contained in it is rapidly decomposed by amylase secreted by microorganisms in the soil in a short time, resulting in the decrease of the mechanical properties of the film. At the same time, the self-oxidant added in the formula reacts with metal salts in the soil to generate peroxide, which breaks the chain of polyethylene and degrades it into small pieces that are easily swallowed by microorganisms, which are absorbed by the natural environment and play a role in improving the soil.

Land is the foundation of human's food and clothing. Today, with the high development of science and technology, land has suffered unprecedented damage. Among them, soil pollution, like a soft knife, is depriving large areas of fertile soil of productivity.

Soil pollution mainly refers to the phenomenon that some harmful substances in the soil greatly exceed the normal content, and the land cannot eliminate the influence of these harmful substances. Serious soil pollution can lead to the decline of crop growth and even wither and die, and these pollution consequences can be found in time. More soil pollution has no obvious performance, but it reduces the quality of agricultural products, especially through the enrichment of harmful substances by crops, which secretly harms livestock and human health, and must be highly vigilant.

Soil pollution mainly comes from domestic sewage and industrial wastewater, waste gas, waste residue, chemical fertilizers and pesticides. Domestic sewage and human and animal manure contain many nutrients that plants need. Irrigation with sewage or application of manure will generally increase crop yield. However, pathogens, viruses, parasites and eggs in these wastewater and wastes enter the farmland and deposit in the soil, causing soil pollution. Human contact with contaminated soil and agricultural products will cause tetanus, epidemic diseases, endemic diseases and parasitic diseases.

once the soil is polluted, its influence is hard to be eliminated. The decomposition of organic pesticides is very slow, and heavy metals are not decomposed at all. Even if the polluted land is no longer polluted, it will still contain high harmful substances in three to five years, and it can be enriched through the food chain and endanger human beings. Therefore, the plants on the seriously polluted land can not only be eaten, but also can not be used as feed or fertilizer. Environmental investigation report composition 411 words 7

Last weekend, my parents and I went to a lake near Zhaomu Mountain and conducted a small-scale environmental investigation.

Let's go around the lake first. We didn't go far before we saw a lot of bottles, scraps of paper, cans, etc., and there was a lot of garbage on the roadside. The garbage bins had been left unattended for a long time, and they all came out, and no one cleaned them. Many people saw that the trash can was full, and no one reminded them, so they threw it on the ground. There are also a lot of scraps of paper on the grass. There are mountains of rubbish in the trash can. Some people throw it into the lake, some on the ground and some in the trash can. Some picnics are over, and plastic bags and food scraps are not collected and dirty.

I think the reason is that people's awareness of protecting nature is not strong, the concept of environmental protection is not formed, public health awareness is not strong, plastic bags, scraps of paper, cans and so on are littered. It is suggested to set up a notice board by the lake or on the lawn, and dispose of the garbage in time, recycle the garbage in time, and remind people not to throw garbage.

In addition, I suggest that city managers should also strengthen management and clean up the scattered garbage in time. Remind people to pay attention to environmental protection in time, and give some punishment to litterers. For example, when they see litterers being caught, they have to clean up for a day, so as to strengthen people's awareness of environmental protection.

Nature is beautiful. I hope people will stop destroying nature and make our home more beautiful. Environmental investigation report composition 411 words 8

On Saturday, my friends and I made an investigation on the environment in my hometown of Wangzhuang.

standing on the side of the road, the first thing you see is a large number of discarded plastic bags, which is the so-called "white garbage". White pollution has a great influence on our lives, and we can see a lot of discarded plastic products in public places. They come from nature, but they are not easily decomposed by nature, thus affecting the ecological environment of nature. People hope to find a kind of plastic that can replace the existing plastic without causing white pollution, but it can't solve the fundamental problem. So I hope everyone can get rid of this bad habit-don't throw white garbage around and make our hometown better.

A gust of wind blew, and the pungent smell came at me. Looking up into the distance, it turned out that the factory chimney was "smoking". There are two big factories in Wangzhuang, which are emitting waste gas from morning till night. These waste gases contain a lot of harmful gases such as carbon dioxide and sulfur dioxide, which seriously affect people's health.

Children, caring for our environment means caring for ourselves. If people don't care for their own environment, what will happen to our hometown in the future? Care about you, me and him, and the environment depends on everyone. Let's work together to create a good and comfortable living environment!

People living in Jingguan Town will know that there is always thick smoke floating near the "big belly" river every day, and at the same time it emits a pungent smell, which makes it difficult for passers-by to breathe. What is the reason for this phenomenon? Taking advantage of the May Day holiday, I made a detailed investigation and understanding of the whole pollution situation of the river with this problem.

After three days' understanding, investigation and visit, I found that there are several reasons for the serious pollution of the "big belly" river:

1. Every morning or evening, factories near the river will discharge black sewage. From a distance, the river looks like a layer of black gauze. And patches of dead fish. The chimney of the factory has turned dark from brown to dark because of the long-term emission of black smoke, and the sky above has also changed from blue to hazy grayish yellow.

2. Littering. Because there is no unified garbage dump, a large amount of domestic garbage is thrown into the river, making this river full of garbage for a long time. However, so much garbage has not been disposed of in time by the relevant departments, which in turn makes the residents here feel helpless. They destroy the river themselves, but they are troubled by the impact of river water pollution on their lives.

3. Burn garbage. Environmental protection workers often burn garbage near the river because of their troubles. The smell emitted when burning garbage is unbearable, and all pedestrians pass by and leave in a hurry.

4. Automobile exhaust. Both gasoline vehicles and diesel vehicles constantly emit exhaust gas during the combustion process, which is mixed with the smell of gasoline.

Environmental pollution has seriously affected the normal life of residents. For the sake of residents' health and safety, I hope the relevant departments will pay attention to this matter and effectively solve these problems. Environmental investigation report composition 411 words 11

Today, my mother said that she would take me to a small park to play.

My mother was very happy when she just said it. She said, "The small park used to be beautiful and lovely, full of children's laughter, but now it's …" My mother seemed afraid to say it. I asked her doubtfully, "What's wrong with you, Mom? Why don't you say it? What is the small park like now? " Mom smiled and said, "Son, you will know when you go." When we arrived at the small park, I opened my mouth wide and asked in surprise, "Mom, mom, why is the small park like this? Why is the small park full of dirty and smelly garbage?" Mother sighed and said, "Because human beings have been throwing garbage, and no one has come to clean it up." I listened and said to my mother, "They don't clean up, let's clean up." My mother looked at me and said, "My daughter has really grown up." I looked around to see if there were any brooms in the small park. I saw three brooms at the door of the small park. I said to my mother, "Mom, look! There are three brooms there. " After that, my mother and I took the broom together, put on a mask and began to clean up the small park. Passers-by saw it and seemed to think: I can't lose to such a small child to clean up the small park. Then he also put on a mask, picked up a broom and swept with us. After our efforts, we finally cleaned up the small park, and the grass stood up gradually. Little bloom produced beautiful flowers. Mom said happily, "The small park is as beautiful as before!"

So, we should protect the environment, so that our life can be happier. Environmental investigation report composition 411 words 11
