Tell me about the environment around you, I need information! ! !

It was a Sunday. My mother and I went for a walk in the community. When we entered the martial arts pool, a pungent smell rushed towards us. We saw such a scene: domestic garbage, All the dead fish were floating on the surface of the pond; the fish in the water were eating the household garbage; someone poured dirty water into the pond... "Mom, it's so disgusting!" I pinched my nose and said to my mother with a straight face. explain. "Yes, if this kind of 'big-bellied' fish is sold in the market, how many people will get sick or even die." Mom said meaningfully.

At this moment, I remembered what I saw on the way to my grandma’s house.

Grandma’s house is located in the urban-rural fringe. The factories there are constantly emitting large amounts of waste gas and waste water. Domestic garbage can be seen everywhere on the road. The construction sites are constantly making noise, which makes nearby residents uneasy. The environment here has deteriorated. The pollution of our surrounding environment is a problem that arises when human beings pursue a higher level of life during the development of material civilization.

In the questionnaire survey we conducted, many Xiamen citizens believed that the environmental protection work in Xiamen urban area was done well, but the urban-rural fringe area was ignored. It was also suggested that garbage classification was not done well, and publicity efforts should be strengthened to attract attention to the phenomenon of littering.

We can only face reality and the crisis. Beyond that, any passive withdrawal won't help. As long as everyone contributes to environmental protection, I firmly believe that one day we will be in harmony with the surrounding environment again, and it will be more lasting and more perfect.

Investigation report on us and the surrounding environment

Deng Weixia, Class 5 (1), Qiaoguang Primary School, Xiangzhou District

Our surrounding environment is very closely related to our lives Relationships are like fish and water, inseparable and no one can live without the other.

Zhuhai is a beautiful coastal city. "The sky is over the sea, the world is under Zhuhai" is the best summary. Zhuhai is beautiful, but there is a "strange color" hidden in the beauty. Because individual citizens do not pay attention to hygiene, they have added a disharmonious "stain" to the beautiful Zhuhai. Under the guidance of the teacher, I investigated our surrounding environment.

White pollution is terrible!

The invention of paper led to the rapid development of human inventions. But in real life, sheets of pure white paper have greatly polluted the human surrounding environment.

Waste of paper: In our class and school garbage pools, there are a lot of paper in the garbage pool every day. Yellow, white, green... it's dazzling. Pieces of brightly colored homework paper were crumpled into a ball.

Paper recycling: During my survey, I found that 95% of people mix recyclable garbage with non-recyclable garbage. "Confused", it turns out that this is the main cause of paper pollution! If people separate garbage and recycle it in categories, the white pollution to the natural environment will be greatly reduced, and our living environment will be greatly different.

Disposable paper cups: In modern life, disposable products are convenient to use, but

problems have arisen that cannot be ignored. Disposable supplies waste resources and pollute the environment. For example: In our daily life, drinking cups are essential. But how should you choose a drinking cup? For the sake of convenience, citizens use disposable paper cups in almost every household. People say it's convenient and cheap. But it is precisely because of the production of disposable paper cups that the environment around us has been extremely damaged. Citizens used disposable paper cups and threw them everywhere, causing serious white pollution.

Water pollution, be careful about your health!

Water is the source of life. Without water, no living thing on earth will be able to survive. The "clear river with fish swimming" was no longer there, and the water was seriously polluted. Maybe you will say, isn’t there bottled drinking water? But drinking bottled water is not the best way to solve water pollution. Drinking bottled water also requires the use of water resources. And drinking bottled drinking water is not very healthy for people's health.

Qianshan River: I once went to Qianshan River for investigation and found that the water in Qianshan River was seriously polluted.

The water in the river is turbid, with a lot of plastic garbage floating on the water, and there is an unpleasant smell from time to time. It turns out that there are many "Three Nos" people living under the Changsheng Bridge. Their actions left a great trauma to Qianshanhe. During the day, they eat, drink, defecate everywhere... If they continue like this for a long time, even the clearest river water will be ruined by them. Nowadays, although the Qianshan River has been tidied up, the water in the Qianshan River is still turbid due to its high sediment content and soil erosion. I was also saddened to see mountains of industrial waste piled next to the Qianshan River.

So, we are punished by nature. Doesn’t our drinking water always taste salty? This is the salty tide in Zhuhai.

During the investigation, I was deeply inspired: we should start from now and start from ourselves. We organized an environmental protection team to carry out environmental protection in action activities and strive to be environmental protection guardians.

Environmental protection in action

During this year’s National Day Golden Week, we issued an initiative to all students in the school: have an environmentally friendly long holiday. We go into society and use our lenses to show the "wonderful" things in the "environmentally friendly" world. We have certain difficulties in using digital cameras: most cameras have an on/off key. Open means ON, close means OFF. The same goes for our digital camera, move the key to ON. Next, we need to adjust the focus, and finally, just press it lightly. When pressing the shutter, your hands should not shake and you should hold the camera steady so that the results will be good. After taking the photo, it is also difficult to send the photo: first, you need to enter the free mailbox, click to write a letter, enter the subject in the box, and write who to send it to. Since you are sending a photo, you have to click to add an attachment, paste the photo, write your name, and then click "Send". With the help of my parents, I finally mastered modern communication skills.

The photos we took were published in the "Life Weekly" of the "Zhuhai Special Administrative Region News" on October 14. The photo on the home page is the work of Zhu Chenwei, a classmate from our school, and the editor specially enlarged it! It seems very conspicuous. The trees are lush and green. Hey! It's made of a plastic can. What an ulterior motive! Look at this scene again: The telephone hall is covered with colorful advertising paper. Our eyes were caught by another photo, this is a photo of people destroying the environment. In the photo is a wall painted with flowers, and there is a sentence written next to the photo: "Give the wall a face." It reminds us to care for the environment all the time.

During the event, I tasted the benefits of modern technology. Using a digital camera made things clearer; emails made communication more comfortable.

The environment depends on you and me, and the environment depends on everyone. As long as everyone loves environmental protection, our surrounding environment will be better!

White pollution

White pollution is a unique environmental pollution in cities in our country. It can be found everywhere in various public places. We can see a large number of discarded plastic products. They come from nature and are made by humans. When they are ultimately attributed to nature, they are not easily absorbed by nature, thus affecting the ecological environment of nature. From the perspective of saving resources, since the main source of plastic products is petroleum resources that are facing depletion, they should be recycled as much as possible. However, because the production cost of recycling at this stage is much higher than the direct production cost, it is difficult to do so under the current market economy conditions. Faced with the increasingly serious problem of white pollution, people hope to find a plastic substitute that can replace the performance of current plastics without causing white pollution. Biodegradable plastics have emerged. This new functional plastic is characterized by reaching a certain level. After its service life is discarded, under specific environmental conditions, its chemical structure undergoes significant changes, causing some performance losses and appearance changes, resulting in degradation, which is harmless or less harmful to the natural environment. For example, if starch is filled in plastic, the starch contained in it will be rapidly decomposed by the amylase secreted by microorganisms in the soil in a short period of time to form holes, resulting in a decrease in the mechanical properties of the film. At the same time, the autooxidant added in the formula reacts with the metal salts in the soil to form Peroxide breaks the chains of polyethylene and degrades it into small fragments that are easily swallowed by microorganisms and are absorbed by the natural environment, while also improving the soil.

Garbage pollution

The phenomenon in which garbage occupies land, blocks rivers and lakes, hinders sanitation, affects landscapes, and harms crop growth and human health is called garbage pollution.

Garbage includes industrial waste and domestic waste. Industrial waste slag refers to waste generated during industrial production and processing, mainly including coal grinding stone, fly ash, steel slag, blast furnace slag, red mud, plastic and petroleum waste residue, etc. Domestic waste mainly includes kitchen waste, waste plastics, waste paper, broken glass, metal products, etc. In cities, due to the increasing population, domestic waste is increasing at a rate of 10% every year, posing a major public hazard.

The serious harm caused by garbage is, first of all, the occupation of a large amount of land. Second, it pollutes farmland. The third is contamination of groundwater. Fourth, it pollutes the atmosphere. Some organic substances in industrial waste can produce odor through biological decomposition at a certain temperature, thus polluting the atmosphere. The fifth is spreading diseases. Domestic garbage contains germs and parasites. If it is used directly as farm fertilizer, people may contract infectious diseases if they eat vegetables and fruits that have been treated with such fertilizer.

With the development of the economy and the improvement of people's lives, the amount of urban garbage has increased significantly. Garbage disposal has become an urgent issue in the comprehensive improvement of urban environment.

Food contamination

Food is one of the three major elements that constitute human life and health. Once food is contaminated, it will endanger human health. Food contamination refers to the various foods that people eat, such as grains, fruits, vegetables, fish, meat, eggs, etc., that are mixed with harmful and toxic substances or germs during the production, transportation, packaging, storage, sales, and cooking processes.

Food contamination can be divided into two categories: biological pollution and chemical pollution.

Biological contamination refers to the contamination of food by harmful viruses, bacteria, fungi and parasites. Bacteria and fungi, which are microorganisms, are invisible to the human eye. When eggs turn rancid and vegetables rot, bacteria and fungi are mainly at work. There are many types of bacteria. Some bacteria, such as Proteus, Flavobacterium, and Enterobacter, can directly contaminate animal food, or they can contaminate animal food through tools, containers, washing water, etc., causing food spoilage. There are many types of fungi, with more than 50,000 species. The earliest mold that served humans was a type of fungus. Nowadays, the fermented bean curd and soy sauce products that people eat are inseparable from mold. However, more than 100 strains of these strains produce toxins, the most toxic of which is aflatoxin. After food is contaminated by this toxin, it will cause primary liver cancer in animals. According to surveys, in areas with high levels of aflatoxin in food, the incidence of liver cancer is dozens of times higher than in other areas. British scientists believe that breast cancer may be related to aflatoxin. The climate in East my country and South-Central China is warm and humid, and aflatoxin contamination is relatively common, mainly on peanuts and corn, followed by rice and other foods.

Parasites that contaminate food mainly include roundworms, tapeworms, trichinella, etc. These parasites generally contaminate water sources and soil through the feces of patients and sick animals, and then contaminate fish, fruits, and vegetables. People will become infected after eating them. Cause parasitic diseases.

Chemical pollution is caused by harmful and toxic chemicals contaminating food. Various pesticides are a major source of chemical pollution in food, as well as industrial wastewater, waste gas and waste residues containing harmful substances such as lead, cadmium, chromium, mercury, and nitro compounds; food colorings, preservatives, color developers, sweeteners, etc. Flavoring agents, curing agents, antioxidant food additives; plastics, paper, metal containers for food packaging, etc. If you use waste newspapers and old magazines to package food, the PCBs contained in these papers will enter the human body through the food and cause illness. PCBs are a general term for more than 200 chlorinated aromatic hydrocarbons, and a large number of them are produced and used in the world today. There is evidence that traces of PCBs have been found in river water, seawater, aquatic organisms, soil, atmosphere, wild animals and plants, human milk, fat, and even in the bodies of penguins in the Antarctic and whales in the Arctic Ocean. During food processing, adding some food coloring can keep the color bright. But some synthetic colors are toxic.

To prevent food contamination, we must not only pay attention to food hygiene, but also start from all aspects of production, transportation, processing, storage, and sales. Only in this way can the problem be fundamentally solved.

Soil pollution

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

Soil pollution mainly refers to the phenomenon that certain harmful substances in the soil greatly exceed the normal content and the land cannot eliminate the influence of these harmful substances. Severe soil pollution can lead to reduced growth and development of crops and even withering and death. These pollution consequences can be detected in time. More soil pollution has no obvious manifestations, but reduces the quality of agricultural products, especially through the enrichment of harmful substances by crops, secretly endangering 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 excrement contain many nutrients that plants need. Using sewage to irrigate fields or apply manure will generally increase crop production. However, pathogenic bacteria, viruses, parasites and eggs in these wastewater and wastes enter farmland and are deposited in the soil, causing soil pollution. Human contact with contaminated soil and agricultural products can cause tetanus, epidemic diseases, endemic diseases, and parasitic diseases.

Modern agriculture uses a large amount of chemical fertilizers, resulting in large amounts of inorganic substances such as nitrates, sulfates, and chlorides remaining in the soil. They destroy the physical and chemical properties of the soil, causing soil compaction and salinization, thereby reducing crop yields. The use of pesticides causes polycyclic aromatic hydrocarbons, polychlorinated biphenyls and other organic matter to settle in the soil, poisoning animals, plants and people.

Hazardous substances such as soot, sulfur dioxide, nitrogen oxides and radioactive dust in the atmosphere will settle into the soil naturally or with rain and snow. Cadmium, lead and other harmful substances in the exhaust gases emitted by smelters and automobiles will also be adsorbed by the soil, causing pollution. The soil around factories and along roads is therefore most susceptible to contamination.

Heavy metal pollution causes the greatest harm among soil pollution. Chromium, manganese, nickel, etc. can also cause cancer in different parts of the human body.

High levels of metals in the soil can also harm plants. According to experiments, when the copper content per kilogram of soil is 20 mg, wheat will wither, and when it reaches 250 mg, rice will also wither. If the zinc content exceeds 50 mg per kilogram of soil, it will affect the growth of crops.

Once soil is contaminated, its effects are difficult to eliminate. Organic pesticides decompose very slowly, and heavy metals do not decompose at all. Even if the polluted land is no longer polluted, it will still contain high levels of harmful substances within three to five years, and can accumulate through the food chain and harm humans. Therefore, plants on severely contaminated land are not only inedible, but also cannot be used as feed or fertilizer.
