Environment is the foundation of human existence, and more and more facts prove that the deterioration of the environment has brought serious disasters to human life. How to protect the environment and realize the sustainable development of society is a problem that everyone on the earth must seriously think about. As citizens of the earth in the 2 1 century, we have the responsibility to work together to leave a beautiful world for our future generations.

In recent years, with the rapid development of regional economy, environmental pollution has become more and more serious. Preventing environmental pollution, protecting the environment and maintaining ecological balance have become important measures for social development and the obligation of every citizen.

The following is a report from the field investigation:

The pollution sources that cause environmental pollution are: 1. The excrement discharged from public toilets gives off an unpleasant smell, which makes people sick. 2. The wastewater discharged from the factory is black and smelly, with some dirt floating. The exhaust gas from the factory is very pungent and will be distributed to every corner of the town. 4. The gas discharged from chemical fertilizer plant contains dust, lead, coal ash and other substances harmful to human body. There are often rubbish discarded by tourists on the park lawn, which is unsanitary and affects the city appearance.

The pollutants that cause environmental pollution are: waste water, waste gas, feces, carrion, plastic bags, wooden chopsticks, garbage and so on.

Pollutants do great harm to the environment and biology: they make the air turbid and do great harm to people's lungs; Poor treatment of domestic garbage will breed bacteria and seriously affect people's health; Sewage will affect domestic water and directly infringe on human body.

After reading so much, are you worried about the present environment? Yes, the environment is closely related to our life. Protecting environmental sanitation starts from me, from now on: no spitting; No littering; Refuse to use disposable wooden chopsticks; Waste batteries and plastic bags should be disposed of; More afforestation, not trampling on the lawn; It is reported that about two-thirds of the cities in China are trapped in a garbage siege. The annual output of "municipal waste" in China is nearly 65.438+0.5 billion tons, and most of these municipal wastes are piled in the open air. It not only affects the urban landscape, but also pollutes the vital atmosphere, water and soil in our lives, posing a threat to the health of urban residents. Garbage has become a thorny problem in urban development. Garbage not only causes public hazards, but also is a huge waste of resources. In the annual output of1.500 million tons of municipal waste, the value of abandoned "renewable resources" is as high as 25 billion yuan! Beijing produces garbage 13000 tons every day, 4.95 million tons every year, and it will increase by 8% every year. At present, there are sanitary landfills in addition to open-air stacking in China. This method avoids the problems caused by open-air stacking. Its disadvantages are large landfill area, short use time (generally about ten years), high cost and waste of recyclable resources in garbage; Incineration reduces the volume of garbage by 50% ~ 95%, but incineration can recycle resources, release toxic gases, such as dioxins and mercury vapor in batteries, and produce toxic slag and dust; The fourth method is composting, which requires people to separate organic garbage from other garbage, and it has a good development prospect. It costs 103.49 yuan to treat a ton of garbage in Beijing now, and the annual treatment cost is more than 500 million yuan. This does not include the cost of building a garbage disposal plant. It takes1~ 200 million yuan to build a large-scale landfill, and more than 2 billion yuan to build a large-scale waste incineration plant, which is another big expenditure. At present, a large amount of unclassified garbage is buried or burned, which is not only a huge waste of resources, but also a secondary pollution. . We are duty-bound to protect the environment!

Poor public awareness of environmental protection is also one of the keys to the success or failure of garbage disposal. Only when everyone has a strong environmental awareness and everyone can really take an active part in environmental protection can we really solve environmental problems. At present, we have not done enough publicity work on environmental protection and garbage disposal. Perhaps Vienna's propaganda work on garbage disposal can be a good reference for us: (1) set up a garbage telephone line to answer all the questions raised by residents about the government's garbage policy; (2) Carry out on-site consultation service and set up mobile consultation stations; (3) Printing garbage pamphlets and distributing them to every household; (4) Primary schools provide publicity materials, starting with children's ideological work; (5) Carry out some outdoor activities to mobilize residents to participate in garbage disposal.

We never thought that garbage would have such a great impact on the national image before, nor did we think that these used garbage would compete with us for living space and affect our lives; Now, we must pay attention to the garbage problem, take action and fight it with action. In this garbage war, as long as we make unremitting efforts, we will definitely become winners. Our Beijing will become more and more beautiful, and we will welcome people from all over the world to bid for the next World Olympic Games with beautiful scenery.

Investigation report on white pollution

1. We counted the number of times packaging bags, snack boxes and plastic products were thrown in a dustbin in front of our house in half an hour: 2 10 times in the morning; Throwing at noon 105 times; 95 times in the evening. This is just a trash can. There are so many waste plastics in one day that it is not difficult to imagine that the waste plastics in the whole country and even the whole earth will be an astronomical figure. 2. We found in a small fast food restaurant: "They can sell about 250 fast food a day, and each fast food needs at least 2 plastic fast food boxes, which means at least 500 plastic fast food boxes a day."

Continuing the second investigation, we visited the industrial and commercial office. The uncle of the industrial and commercial office warmly received us. We know that there are about 200 fast food restaurants, large and small. According to this calculation, as many as 10000 discarded plastic snack boxes are produced in one day.

We went to Xinhua Bookstore and looked up information in the school library, but there was little information about "white pollution". Looks like we have to find another way.

5. We went to the Health Bureau. My uncle told us that more than 300 sanitation workers are working hard for environmental sanitation every day. There, we also learned the true composition of "white pollution" and preliminarily understood the harm of "white pollution".

6. In order to get rid of the predicament, with the help of the teacher, we use the Internet to do research. We found a vast space on the Internet, which gave us a deeper understanding of "white pollution". This is very helpful for us to write a paper.

Second, what is "white pollution"?

"White pollution" has become a well-known new term. So what is "white pollution"? "White pollution" mainly refers to the environmental pollution caused by white foamed plastic lunch boxes, various plastic bags and agricultural plastic films. The main components of "white pollution" are polyethylene (PE), polyvinyl chloride (PV), polypropylene (PP) and polystyrene resin (PS). Plasticizer, foaming agent, heat stabilizer, antioxidant, etc. Also added to these pollutants.

Third, the main reasons for "white pollution":

1. Plastic garbage has not been properly managed and treated, and garbage has not been collected separately. What can be recycled is not recycled.

2. Many enterprises do not treat the white garbage produced in the production process scientifically and let it drift.

3. China's existing laws do not deal with plastic packaging waste, and have formulated excellent relevant laws and regulations.

4. Although our city has become much cleaner under the slogan of creating a provincial civilized and sanitary town, on the whole, people's awareness of environmental protection is still relatively weak, and the abuse and random dumping of plastic products are quite common.

Fourth, the harm of "white pollution":

(1) Visual hazard:

The plastic garbage scattered in the environment ruined the city appearance. Such as disposable foamed plastic tableware scattered in the natural environment, streets and lanes, rivers and lakes, and ultra-thin plastic bags flying all over the sky or hanging on branches, which bring bad stimulation to people's vision.

(2) Potential hazards:

1. Plastic film waste remains in the soil in a large area and accumulates for a long time, causing soil hardening, affecting crops' absorption of nutrients and water, and leading to crop yield reduction.

2. Plastic garbage discarded on land or in water will lead to the death of animals if it is swallowed as food.

3. The plastic garbage entering the domestic garbage is light in weight, large in volume and difficult to handle. If they are buried, they will occupy a lot of land and it will be difficult to decompose for a long time.

4. Some plastics are poisonous. If they are used as tableware or food packaging materials, they will be harmful to human health.

5. The ozone layer is thinning.

We are particularly interested in the harm of "ozone layer thinning". Because plastic waste generally exists on the ground, and the ozone layer exists in the sky, so far apart, how can it matter? After consulting materials, books and some teachers, the conclusion is that white pollution releases a lot of poisons in plastics into the atmosphere through the radiation of the sun, and the ozone layer is above the atmosphere, making the ozone layer gas gradually thinner. We all know that the sun is a kind of "big fireball", which naturally glows and heats up at tens of thousands of degrees. Steel has turned into gas before it reaches several kilometers. How can such a high temperature not destroy the earth? In order to prevent the earth from being greatly damaged, the ozone layer has really made great contributions. When the sun assisted shooting, it stood up and blocked the attack again and again. But because "white pollution" does destroy the ozone layer and make it thinner, it will be a huge crisis for the earth.

Verb (abbreviation for verb) takes action to control "white pollution"

Through this survey, we know that with the rapid development of industrial and agricultural production, it has created unprecedented huge material wealth for mankind and paid a heavy price for the environment. Ecological destruction and environmental pollution have posed a serious threat to human survival and development. When it is windy, the air is filled with yellow dust, and sometimes white plastic bags fly in the air. It's embarrassing to go out. Therefore, solving environmental problems has become an urgent and important task. Although more than 300 sanitation workers struggle with "white pollution" day and night every day. However, to change this situation, it is far from enough to rely solely on the efforts of sanitation workers. We must also improve our environmental awareness. Environmental pollution and destruction are not caused by one person, so protecting the environment should be the behavior of the whole society. Each of us has an obligation to protect the environment. At the same time, we also understand that we are the masters of society, and improving the global environment is the unshirkable responsibility and obligation of our generation. We should strive to raise awareness of environmental protection and save resources. If everyone in the world destroys it every day, the earth will become a garbage dump; If everyone in the world is environmentally friendly every day, we can create a beautiful world. Let's join hands to protect the earth and our home. To this end, we suggest starting from ourselves, starting from small things, so as to:

1, don't litter and waste, put the garbage in the designated dustbin.

2. Set up a "garbage sorting place" and actively participate in and publicize it.

3. Don't waste, including not wasting a piece of paper, a drop of water and a penny.

4. Try not to use plastic bags, use less plastic bags, and actively use renewable products to reduce white pollution.

5. Find behaviors that damage the surrounding environment, and promptly remind and stop them.

6. Love, understand, protect and make friends with nature. I believe that through the joint efforts of all of us, our home will become more and more beautiful. Let's take the activity of striving for a civilized and hygienic city as a new starting point, and take action to protect the environment and protect the earth's homeland! Through this self-organized activity, we have a deep understanding of environmental protection knowledge, increased social knowledge and exercised social practice ability. We all think this activity is very successful.
