Social Report on Environmental Pollution In real life, plastic bags have become something we can't live without. With the improvement of living standards, "disposable" household appliances have gradually entered people's lives. However, behind the "simplicity and convenience", how many people know the consequences of leaving a plastic bag, a snack box or other disposable tableware? The situation of white pollution cannot be ignored! I hope our investigation report can make some people who haven't realized the seriousness of "white pollution" become future environmental protection pacesetters! And treat the earth as a pure land! 1. How is "white pollution" formed? These refractory plastic products are mainly treated by "burying and burning". However, burying plastic products will destroy the soil structure, make the soil lose its fertilizer efficiency and make nothing grow, while burning plastics (especially chlorine-containing plastics) will pollute the atmosphere. Second, the harm of "white pollution": "white pollution" has two kinds of harm: visual pollution and potential harm. Visual pollution refers to plastic bags, boxes, cups and bowls scattered in the environment, which bring bad stimulation to people's vision and affect the aesthetic feeling of the environment. The potential harm of "white pollution" is various. 1, disposable foamed plastic lunch boxes and plastic bags for food seriously affect our health. When the temperature reaches 65℃, harmful substances in disposable foamed plastic tableware will penetrate into food, causing damage to human liver, kidney and central nervous system. The ultra-thin plastic bags we use to hold food now are generally PVC plastic. As early as forty years ago, it was found that vinyl chloride monomer remained in PVC plastics. When people are exposed to vinyl chloride, there will be symptoms such as wrist and finger edema and skin sclerosis, and spleen enlargement and liver damage may also occur. In China, almost all the ultra-thin plastic bags we use come from the reuse of waste plastics, which are produced by small enterprises or family workshops. The raw materials used in these factories are discarded plastic barrels, cans and disposable syringes. In production, the raw materials are crushed into plastic particles by machinery, then the plastic particles are put into a pool for cleaning (called disinfection), taken out and dried, and then pressed into films by machinery to make various plastic bags. Every time when eating, many people put their meals in plastic bags. They don't know that this kind of behavior not only harms the environment, but also harms their own health. 2. Deteriorating the soil environment and seriously affecting the growth of crops. The degradation time of plastic products currently used in China usually takes at least 200 years. Long-term residue of discarded agricultural films and plastic bags in farmland will affect the absorption of water and nutrients by crops, inhibit the growth and development of crops, and cause crop yield reduction. If livestock eat plastic film, it will cause digestive tract diseases and even death. 3. Landfill is still the main way to deal with municipal waste in China. Due to the low density and large volume of plastic film, it can quickly fill the site and reduce the ability of landfill to treat garbage; Moreover, due to the soft foundation of the landfill, harmful substances such as bacteria and viruses in the garbage can easily penetrate into the ground, pollute the groundwater and endanger the surrounding environment. 4. If waste plastics are burned directly, it will cause serious secondary pollution to the environment. When plastics are burned, it will not only produce a lot of black smoke, but also produce dioxin, which is by far the most toxic substance. It takes at least 15 months for dioxins to decompose gradually after entering the soil, which is harmful to plants and crops. Dioxin has serious damage to the liver and brain of animals. The environmental pollution caused by dioxins produced by garbage incineration has become a sensitive issue of concern all over the world. Third, paper products cannot be used instead of plastic products. In addition, because disposable plastic tableware is difficult to degrade, many cities are now promoting the use of green tableware-paper tableware. The principle is that cellulose, the component of paper products, can be degraded by microorganisms. However, it is unwise to use paper tableware instead of foamed plastic tableware. First of all, paper tableware will also bring visual pollution. Their degradation speed is not fast, and often they will not be completely degraded for dozens of days or even months. Secondly, when making paper and tableware, in addition to straw pulp and rice pulp, wood pulp of about 1/3 should be added. If fully promoted, it will inevitably lead to the consumption of a large number of wood and the intensification of deforestation. However, the forest coverage rate in China is only 13.92%, and the per capita forest area is only 17.2% of the world average. Thirdly, pulping has always been a big consumer of water, energy and sewage. The pulping process needs a lot of water, and China is a country short of water. If the sewage is directly discharged into the river without treatment, it will cause water pollution; Paper tableware needs to be dried immediately after forming, which consumes a lot of energy. China's energy structure is dominated by burning coal, which will increase the content of SO2 in the air and cause acid rain. Third, how to correctly prevent and control "white pollution"? 1, to minimize the use of disposable plastic tableware and paper tableware. Any disposable tableware is not only not conducive to environmental protection, but also the biggest waste of resources. We should not rely too much on plastic bags in our daily life. In the store, you can use one or two plastic bags to sort the goods. The weight of the goods is completely within the allowable range of the bags, but some customers simply ask for one or two more bags. Most consumers take supermarket plastic bags home as garbage bags, which will cause secondary pollution to the environment after being discarded. Therefore, we should refuse to use plastic bags to buy food or hold food. We can use vegetable baskets or cloth bags to avoid one-time use and reduce environmental pollution. You can use your own stainless steel or plastic lunch box to pack food, which is hygienic and environmentally friendly and will not cause harm to your body. 2. Recycling waste plastics is the fundamental way to solve white pollution. In fact, compared with other materials, plastics have a significant advantage: they can be easily recycled. After plastic recycling, it can not only be recycled into products, but also be made into gasoline and diesel oil. In recent years, in Germany, Japan, the United States and other countries, due to the emphasis on the recycling of packaging materials, a virtuous cycle of plastic production, use, recycling and reuse has been realized, and white pollution has been fundamentally eliminated. In China, recycling of waste plastics has begun. We should cooperate with relevant government departments to classify wastes so that the recycling work can be carried out smoothly. 3. Strengthening environmental protection propaganda, raising citizens' awareness of environmental protection and forming a good environmental protection atmosphere in society are the prerequisites for solving white pollution and other forms of pollution. For example, to recycle waste plastics, it is necessary to implement the garbage recycling and sub-packaging system and put different kinds of garbage in different trash cans, which requires us to have a high degree of conscious awareness of environmental protection. Do you know more about white pollution after reading the above? What measures have we taken to deal with white pollution in China? Recently, the General Office of the State Council issued the Notice on Restricting the Production, Sale and Use of Plastic Shopping Bags, stipulating that "plastic shopping bags shall not be provided free of charge"; From June 1 2008, the production, sale and use of plastic shopping bags (ultra-thin plastic bags) with a thickness of less than 0.025mm are prohibited nationwide. The reporter interviewed some ordinary citizens in Guangzhou yesterday. Most of them expressed their understanding of restricting the use of plastic bags to protect the environment, but many citizens thought that businesses should pay more for "white pollution". The relevant person in charge of the National Development and Reform Commission said yesterday that according to estimates, the waste plastic that enters the landfill with domestic garbage accounts for 3% to 5% of the weight of landfill garbage every year in China, most of which are waste plastic shopping bags, especially ultra-thin plastic bags. Some experts say that ultra-thin plastic bags use less raw materials than thick plastic bags and are easier to degrade. Why not ban the production of non-environmental plastic bags instead of ultra-thin plastic bags? There are also many citizens who question that even if a garbage bag increases its price by two or three cents, many people are still willing to pay. This will not have obvious effect on controlling the use of plastic bags. Some experts pointed out that the key to control "white pollution" is to start from the source, prohibit the production of plastic bags in the production process, or increase the production cost of plastic bags. Require manufacturers to pay more taxes, so that environmentally unfriendly plastic bags will gradually withdraw from the market, and at the same time use the collected taxes for pollution control. Although some people may think that charging can't control the spread of white pollution well, it is a good start. It can be seen that our government and people attach great importance to the problem of white pollution, and we have begun to take actions to make up for our environment. This has to give us hope and confidence. In fact, it is not difficult to end the bomb of "white pollution", and its fuse is our human actions. Only by reducing the use of plastic products from now on, or even refusing to use plastic products, will the bomb not be ignited and will disappear from the earth. The earth is the only place where everyone lives, and it is our responsibility to protect it from pollution!
