Try to be less, about 100 to 200 words. Hurry, hurry, hurry! Hurry up!!!!

waste packaging plastics discarded in the environment will not only affect the city appearance and natural landscape, produce “visual pollution”, but also be difficult to degrade, and cause potential harm to the ecological environment. For example, mixing in the soil will affect the absorption of nutrients and water by crops and lead to crop yield reduction

the seepage of plasticizers and additives will lead to groundwater pollution; Burning together with municipal waste will produce harmful gases, pollute the air and damage human health; Landfill treatment will occupy land for a long time, and so on

the waste plastic packaging scattered around cities, tourist areas, water bodies and roads brings adverse stimulation to people’s vision, affects the overall beauty of cities and scenic spots, destroys the city appearance and scenery, and thus causes “visual pollution”

first, discarded waste plastic packaging on land or in water is swallowed by animals as food, resulting in animal death (such situations are common in zoos, pastoral areas and oceans); Second, it is difficult to recycle the plastic waste that is used in the landfill for a long time, and it is difficult to recycle the plastic waste

what people strongly reflect is mainly the problem of “visual pollution”, while most people still lack understanding of the long-term and deep-seated “potential harm” of waste plastic packaging

1. Excessive land occupation. Plastic waste also stays in nature for a long time, generally up to 200-400 years, and some up to 500 years

2. Air pollution. Plastic, paper scraps and dust fly in the wind

3. Polluted water body. Plastic bottles and lunch boxes floating on the surface of rivers and sea water, plastic bags and bread paper hanging on the branches above the water not only cause environmental pollution, but also if animals eat white garbage by mistake, they will hurt their health and even starve to death because they can’t digest in the digestive tract

4. Fire hazard. Almost all white garbage is combustible. Methane and other combustible gases will be produced in the process of natural stacking. Fire accidents easily caused by open fire or spontaneous combustion continue to occur, often causing heavy losses

5. White garbage may become a nest for pests. They can provide food, habitat and breeding places for mice, birds, mosquitoes and flies, and the residues in them are often the root cause of infectious diseases

6. After entering the environment, waste plastic packaging is difficult to degrade, resulting in long-term and deep-seated ecological and environmental problems. First of all, waste plastic packaging materials mixed in the soil will affect the absorption of nutrients and water by crops, which will lead to crop yield reduction; Secondly, if livestock eat plastic film, it will cause gastrointestinal diseases and even death of livestock

7. Because of its large volume, bacteria will breed in the landfill and pollute the groundwater

major plastic polluters

in 2018, about 513 million tons of plastic flowed into the sea every year, of which 83.1% came from the following 20 countries: China is the largest plastic waste polluter, accounting for 27.7% of the world’s total, the second Indonesia is 10.1%, the third Philippines is 5.9%, the fourth Vietnam is 5.8%, and the fifth Sri Lanka is 5.0%

Thailand ranked sixth with 3.2%, Egypt ranked seventh with 3.0%, Malaysia ranked eighth with 2.9%, Nigeria ranked ninth with 2.7%, Bangladesh ranked tenth with 2.5%, South Africa ranked eleventh with 2.0%, India ranked twelfth with 1.9%, Algeria ranked thirteenth with 1.6%, Turkey ranked fourteenth with 1.5%, Pakistan ranked fifteenth with 1.5%, Brazil ranked sixteenth with 1.5%, Myanmar ranked seventeenth with 1.4%

18 Morocco 1.0%, 19 North Korea 1.0%, 20 United States 0.9%. According to a study published by science and jambeck et al. (2015), the rest of the world generates 16.9% of poorly managed plastic waste in the ocean

in 2020, a new study revised the potential contribution of the United States to plastic mismanagement in 2016. It is estimated that 0.15-0.99 metric tons of plastics are used for recycling in the United States every year, and 0.14 and 0.41 metric tons are illegally dumped in the United States

therefore, it is estimated that the amount of plastic produced by the United States entering the marine environment may be as high as 1.45 metric tons, leaving the United States behind Indonesia and India in marine pollution, or as low as 0.51 metric tons, leaving the United States behind Indonesia, India, Thailand, China, Brazil, Philippines, Egypt, Japan, Russia and Vietnam

refer to & nbsp; Baidu Encyclopedia – white pollution

white pollution has two hazards: visual pollution and potential hazards
visual pollution refers to the scattering of plastic bags, boxes, cups and bowls in the environment, which brings adverse stimulation to people’s vision and affects the beauty of the environment
the potential harm of white pollution is multifaceted
1.
disposable foamed plastic lunch boxes and plastic bags containing food seriously affect our health. When the temperature reaches 65 ℃, the harmful substances in disposable foamed plastic tableware will penetrate into the food and cause damage to human liver, kidney and central nervous system
the ultra-thin plastic bags we use to hold food are usually PVC plastic. As early as 40 years ago, it was found that vinyl chloride monomer remained in PVC plastics. When people are exposed to vinyl chloride, they will have symptoms such as swelling of wrists and fingers, hardening of skin, splenomegaly, liver injury and so on. 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 waste plastic barrels, pots, disposable syringes, etc. During production, first crush the raw materials into plastic particles by machinery, then wash the plastic particles in a pool (called disinfection), take them out and dry them, and then press them into a film by machinery to make various plastic bags. Every time they eat, many people pack their meals in plastic bags. They don’t know that this behavior is not only harmful to the environment, but also to their own bodies
2,
worsens the soil environment and seriously affects the growth of crops. The degradation time of plastic products currently used in China usually takes at least 200 years. The long-term residue of waste agricultural film and plastic bags in farmland will affect the absorption of water and nutrients by crops, inhibit the growth and development of crops, and reduce the yield of crops. If livestock eat plastic film, it will cause gastrointestinal diseases and even death
3,
landfill operation is still a main method of urban waste treatment in China. Due to the small density and large volume of plastic film, it can quickly fill the site and reduce the waste treatment capacity of the landfill site; Moreover, due to the soft foundation of the landfill site, the bacteria, viruses and other harmful substances in the garbage can easily penetrate into the ground, pollute the groundwater and endanger the surrounding environment
4.
if waste plastics are directly incinerated, it will cause serious secondary pollution to the environment. When plastic is burned, it will not only produce a large amount of black smoke, but also produce dioxin, the most toxic substance so far. Dioxin can decompose gradually after entering the soil for at least 15 months, which will harm plants and crops; Dioxin has serious damage to the liver and brain of animals. The environmental pollution caused by dioxins emitted from waste incineration has become a very sensitive issue of concern all over t
he world
in addition, because disposable plastic tableware is difficult to degrade, many cities now promote 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 also unwise to replace foamed plastic tableware with paper tableware. First of all, paper tableware will also bring visual pollution. Their degradation rate is not fast, and they will not degrade completely in dozens of days or even months. Secondly, when making paper tableware, in addition to straw pulp and rice pulp, about 1 /3 of wood pulp should be added. If it is fully popularized, it is bound to cause a large amount of wood consumption and aggravate deforestation. However, China’s forest coverage rate is only 13.92%, and the per capita forest area is only 17.2% of the world’s per capita level. Third, pulp making has always been a large water consumer, energy consumer and sewage polluter. The pulping process needs a lot of water, and China is a country with a shortage of water resources. 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 requires a lot of energy. China’s energy structure is dominated by coal, which will increase the content of SO2 in the air and cause acid rain.

the main harm of “white pollution” lies in “visual pollution” and “potential harm”:

visual pollution
the waste plastic packaging scattered in cities, tourist areas, water bodies and roads brings adverse stimulation to people’s vision, affects the overall beauty of cities and scenic spots, destroys the city appearance and landscape, and thus causes “visual pollution”

potential harm
after entering the environment, waste plastic packaging is difficult to degrade, resulting in long-term and deep-seated ecological and environmental problems. First of all, waste plastic packaging materials mixed in the soil will affect the absorption of nutrients and water by crops, which will lead to crop yield reduction; Second, discarded waste plastic packages on land or in water are swallowed by animals as food, resulting in animal death (such situations are common in zoos, pastoral areas and the sea); Third, the waste plastic packaging mixed with domestic waste is difficult to deal with: landfill treatment will occupy land for a long time, the domestic waste mixed with plastic is not suitable for composting treatment, and the sorted waste plastic is difficult to recycle because the quality cannot be guaranteed
what people strongly reflect is mainly the problem of “visual pollution”, while most people still lack understanding of the long-term and deep-seated “potential harm” of waste plastic packaging.

the harm of white pollution to human health lies in the impact of using disposable foamed plastic lunch boxes and plastic bags to contain food on our health. When the temperature reaches 65 ℃, the harmful substances in disposable foamed plastic tableware will penetrate into the food and cause damage to human liver, kidney and central nervous system. The ultra-thin plastic bags we use to hold food are usually PVC plastic. As early as decades ago, it was found that vinyl chloride monomer remained in PVC plastics. When people are exposed to vinyl chloride, they will have symptoms such as swelling of wrists and fingers, hardening of skin, splenomegaly, liver injury and so on. Almost all the ultra-thin plastic bags we use come from the reuse of waste plastics and are produced by small businesses or family workshops.

Every time they eat, many people pack their meals in plastic bags. They don’t know that this behavior is not only harmful to the environment, but also to their own bodies. The harm of white pollution to the environment should not be underestimated. Waste agricultural films, plastic films for packaging, plastic bags and disposable plastic tableware invade too much land.
