The social practice you are browsing is the World Green Society Practice Report. People have many such experiences: a big box of gifts, which is mostly foamed plastic when opened; Go to the store to buy a toothpaste or a box of toys, and the salesman will pack it in a small plastic bag; Go to a fast food restaurant, and the waiter will give you a meal in a plastic box. When you go to the farmer's market, you can collect a lot of plastic bags, vegetables, fruits, meat and rice noodles ... all of which are packed in plastic bags for you. Even if you buy garlic, you will pack it in small plastic bags. Plastic products bring a lot of convenience to our life and are cheap. However, have you ever thought that it not only provides convenience for people, but also brings people a "white disaster"? We have conducted various investigations and studies, consulted various materials, and analyzed and summarized them. 1. Our investigation and study: 1. We counted the times of throwing large and small packaging bags, snack boxes and plastic products in a trash can in front of Jiang Yiting's house on Fangchi Road within 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 on Qinqin South Road: "They can sell about 250 fast foods 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." 3. Continuing the second investigation, we visited Wuyuan Town Industrial and Commercial Office in Haiyan County. Uncle Wang of the industrial and commercial office warmly received us. We know that there are about 200 fast food restaurants in Wuyuan Town, Haiyan. According to this calculation, there are as many as 10000 discarded plastic snack boxes in Wuyuan Town alone. 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 Environmental Sanitation Center of Wuyuan Town, Haiyan County. Grandpa Jiang of the Environmental Sanitation Institute told us that in Wuyuan Town, Haiyan County, more than 300 sanitation workers are working hard for the environmental sanitation of Haiyan 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 causes of "white pollution" are: 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 county 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 phenomenon of abusing and dumping plastic products at will is quite common. Fourth, the harm of "white pollution": (1) Visual harm: plastic garbage scattered in the environment damages 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 hazard: 1. Plastic film waste remains in the soil in a large area and accumulates for a long time, which causes soil hardening, affects the absorption of nutrients and water by crops, and leads 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. Take 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 at the same time it has 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. In Wuyuan Town, Haiyan County, although more than 300 sanitation workers fight against "white pollution" day and night. 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, and doing: 1, not littering, and putting the garbage in the designated garbage bin. 2. Our school has set up a "garbage sorting place", so we should actively participate 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. when you find that there are behaviors that destroy the environment around you.
