Plastic Products and Environmental Protection
Abstract：It must be known to all that plastic products are widely used in various fields and are indispensable to our daily life or come into contact with each other every day. Moreover, plastic products are decorative and can be made into transparent products or products of various colors with beautiful and durable color. However, plastic products also bring pollution and damage to our living environment. Therefore, this article mainly narrates the most fundamental harm of plastic products, analyzes the reasons why it is difficult to control nowadays, and finally puts forward some measures.
Key words: plastic products pollute the environment
There are many phenomena about plastic products around us: on university campuses, many students do not want to go to the canteen to eat, feel that going to the canteen is too troublesome and too far away and buy take-out food or ask students to pack it up and take it back to the dormitory; Some students bought snacks to take back to the dormitory. Even some students buy food directly on the relevant APP. And all the packages they buy are plastic products. For example: lunch boxes, snack bags, shopping bags. Nowadays, with the development of science and technology, the living standard has also been improved. You can also buy some articles and foods you need online at home. Most of the packages you receive are packed in plastic bags. It is often seen in schools that garbage cans are full of plastic express bags. And back to my hometown, there are many plastic bags that have been thrown away for a long time and some that have just been thrown away. If I go to the riverside, I will be lying on the riverside in vain.
Plastic products have improved the quality of modern human life and promoted the progress of human civilization. Food, clothing, housing, transportation, communication and entertainment, which are closely related to everyone’s daily life, are closely bound up with plastic products, which have become an indispensable part of everyone’s daily life. It is the environmental protection question that makes people hate plastic bags. The question of environmental pollution does not lie in the plastic itself. What is more crucial is to recover and utilize the plastic bags in a timely and scientific manner and to dispose of them without pollution, so as to turn waste into treasure! Using petroleum as raw material, ethylene, propylene, vinyl chloride, styrene, etc. can be prepared. Under certain conditions, the molecules of these substances can react with each other to produce compounds with large molecular weight (i.e., polymers): polyethylene, polypropylene, polyvinyl chloride, polystyrene. Since the 1960s, plastics have entered a stage of widespread application. As plastic has many advantages: it is easy to obtain materials, low in price, easy to process and light in texture, plastic has been very popular in the world as soon as it comes out. It quickly permeates into all aspects of social life. Plastic is made into bowls, cups, bags, pots, barrels, pipes, etc. With the continuous increase of plastic output and lower cost, a large number of agricultural films, plastic bags for packaging and disposable plastic tableware that we have used are discarded in the environment after use, causing great damage to the landscape and the environment. As most plastic packages are white, the environmental pollution they cause is called white pollution.
I. Hazards of Plastic Products The harm of plastics plastic garbage, disposable plastic bags, plastic lunch boxes accounted for a larger proportion. The most obvious increase in plastic waste is in busy urban areas and living areas with high consumption levels. The hazards are: (1) plastic landfill damages soil structure. Embedding plastic and other garbage into the soil is a common way for human beings to dispose of garbage. However, plastic is non-degradable. Even if it is buried deep, it will not decay and degrade for 200 years. It is extremely destructive to the soil structure. After the agricultural plastic film is aged, the fragments left in the field will not decompose and rot, which will affect the crops to absorb water and nutrients and lead to crop yield reduction. Plastic is easy to form bundles. It can even block water flow, causing water conservancy facilities and urban facilities to malfunction and lead to disasters. (2) Burning plastic to pollute the air. Due to limited land resources, in addition to landfill, people also burn plastic and other garbage. Burning plastic will produce a large number of harmful gases and toxic smoke, not only damaging the ozone layer, but also a large part of it will be inhaled by people, seriously endangering human health. (3) Plastic littering pollutes the visual environment. In rural areas, scenic spots, railways, rivers and lakes, we often see plastic bags floating around in colorful patterns, like sand falling into our eyes, stinging our eyes. (4) Producing plastic consumes a lot of resources. Chinese citizens use about 3 billion plastic bags every day, with an annual usage of more than 1 trillion. Therefore, it takes 3 tons of oil per ton of plastic bags produced in our country, and the amount of plastic bags used in our country every year can be used by at least 3 million ordinary cars for 5 years. One third of China’s imported oil is used for disposable plastic synthetic products every year. (5) endangering human and animal health. Disposable foamed plastic lunch boxes and plastic bags containing 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, and seriously threatening people’s health. Rural, pastoral, zoo and marine animals sometimes swallow plastic into their stomachs by mistake, endangering their health.
II. Reasons for Difficult Control of “White Pollution”
(1) It is difficult to change residents’ consumption habits. Over the years, people have formed the habit of enjoying free plastic bags. The pace of modern life is quickening. Many people go straight to the farmer’s market or supermarket after work. They are unlikely to go home to pick up the basket or cloth bag before buying vegetables or shopping. Many people are not used to carrying shopping bags, which is too troublesome or inconvenient. The huge demand for plastic bags drives large and small production enterprises and small workshops to produce large quantities of cheap plastic bags in both light and dark. (2) The public’s awareness of environmental protection is weak. Many people know very little about the environmental pollution caused by plastic bags and articles commonly used in battery life. Some people know a little about it, but sometimes the idea of convenience and convenience will overcome the fleeting idea of environmental protection. (3) The price of substitute goods is too high. Many people know that plastic bags pollute the environment and that reusable shopping bags is very environmentally friendly. However, because the price in reusable shopping bags is too high, people who are accustomed to free plastic bags are not willing to spend “big money” on shopping bags, but are more willing to spend a few cents on plastic bags, or simply enjoy free plastic bags at stalls outside, which is convenient and economical. (4) Not easy to recycle. The cost of recycling is high, but the utilization rate is low. Businesses can be said to be unprofitable, and it is difficult to attract the general public to carry out “white recycling” due to its low recycling price. Therefore, the phenomenon of difficult recovery occurs. (5) Waste plastic landfill will not only occupy a large amount of land, but also the occupied land will not be restored for a long time, affecting the sustainable use of land. It is extremely harmful to the land, changing its pH value, affecting the absorption of nutrients and water by crops, resulting in a reduction in agricultural output and destroying the ecological balance.
III. Measures to “White Pollution”
(1) Intensify the propaganda of the harm of “white pollution” and cultivate people’s awareness of environmental protection. It is necessary to take various forms to publicize the harm of “white pollution”. For example, by setting up TV columns, posting public service advertisements in public places such as communities, schools, villages, media, stations, buses, shopping malls, bazaars, etc., and introducing relevant environmental protection knowledge into the classrooms of primary and secondary schools, it is necessary to widely publicize the important role of the “plastic restriction order” in the implementation of graduation theses, popularize the hazards of using waste plastic to produce ultra-thin plastic bags for food packaging and relevant safety knowledge, etc., to raise awareness of the harm of “white pollution”, and to educate and develop good health habits. (2) Promote and popularize environmental protection substitutes. To limit and reduce the use of plastic, it is far from enough to rely on people’s self-discipline alone. The government should consider more from the perspective of convenience to the public and economy and practicality, and increase the research and development and production of convenience bags, environmental protection bags and degradable bags, such as the production of disposable tableware and shopping bags with pulp, plant (such as corn, straw, straw) fiber and other raw materials. (3) Establish a restraint mechanism and supervision mechanism, and increase the punishment. The policies and regulations that we are going to formulate will impose a fine of more than 10 times the profits of enterprises that still produce plastic bags illegally, or close down factories that produce and sell plastic bags, so as to prevent “white pollution” from occurring at the source. It is also necessary to strengthen the management of industries that produce a large number of waste plastic packaging materials, and to change the phenomenon of no one being responsible, disorderly stacking and random disposal. (4) The phenomenon of free delivery of plastic products in supermarkets and stores should be well managed. If there is no free plastic bag to send, I believe that most shoppers will recycle the bag once they buy it, thus forming a habit is a virtue. One person’s actions are believed to be seen by everyone and will eventually be acted upon by everyone. (5) Compulsory recycling. Clean waste plastic packaging can be reused or reused for granulation, oil refining, paint making, building materials, etc. Recycling conforms to the general principle of “reduction, recycling and innocuity” for solid waste treatment. Recycling can not only avoid “visual pollution”, but also solve “potential hazards”, relieve resource pressure, reduce the load of municipal solid waste disposal, save land and obtain certain economic benefits.
A good living environment requires us to create it ourselves and to take good care of it. Therefore, the quality of the environment is closely related to us. The lunch boxes in the canteen sell so many boxes every day. It must be unknown how many boxes are accumulated. The physical harm and environmental damage caused by it are unimaginable. At this stage, we can only enhance our awareness of environmental protection. At the same time, we should start from ourselves, start from small things around us, and be an environmentalist who takes care of the environment and pays attention to the environment.
