Plastic bags do bring convenience to our lives, but the convenience at this time brings long-term harm. The recycling value of plastic bags is low, in addition to being scattered in urban streets, tourist areas, water bodies, roads and railways during use In addition to causing "visual pollution" pollution on the side, it also has potential hazards. The plastic structure is stable, not easy to be degraded by natural microorganisms, and will not be separated for a long time in the natural environment. This means that if the waste plastic waste is not recycled, it will become pollutants in the environment, which will permanently exist and accumulate, which will cause great harm to the environment. First, it affects agricultural development. Waste plastic products continue to accumulate in the soil, which will affect the absorption of nutrients and water by crops, resulting in reduced crop yields. Second, it poses a threat to the survival of animals. Waste plastic products discarded on land or in water are swallowed by animals as food, resulting in animal death. Nearly 1,000 sheep were killed in 20 herdsmen's families by the Qinghai Lake, and the economic loss was about 300,000 yuan. Sheep like to eat the oily residue wrapped in plastic bags, but they often eat it together with the plastic bags. Because the plastic they eat stays in the stomach for a long time and it is difficult to digest, the stomachs of these sheep are full and can no longer be eaten. Things can only be starved to death in the end. Such things are common in zoos, pastoral areas, rural areas, and oceans. Third, waste plastics will not only occupy a lot of land with landfill, but the occupied land will not be restored for a long time, which will affect the sustainable use of land. If the waste plastic products entering the domestic waste are landfilled, they will not degrade for 200 years. It is extremely harmful to the land, changing its pH, affecting the absorption of nutrients and water by crops, resulting in reduced agricultural production. As for plastic products discarded in water or on land, it not only affects the environment, but also leads to death if swallowed by animals. This destroys the ecological balance. Fourth, high temperature decomposes toxic substances. Plastic products are originally non-toxic, but because its recycling equipment is not perfect, the process is simple, and many manufacturers do not have legal business licenses, the temperature of recycled plastic products reaches 65 ℃. At the same time, toxic substances will be precipitated and infiltrated into food, which will cause harm to important parts of the human body such as the liver, kidneys, reproductive system and central nervous system. Not long ago, the General Office of the State Council issued the "Notice on Restricting the Production and Sales of Plastic Shopping Bags" to the people's governments of provinces, autonomous regions, and municipalities directly under the Central Government, ministries and commissions of the State Council, and agencies directly under the Central Government. The notice pointed out: In view of the fact that shopping bags have become the main source of "white pollution", the people's governments, ministries and commissions of various places should prohibit the production, sale and use of ultra-thin plastic shopping bags in the future, and will implement a system of paid use of plastic shopping bags. Since June 1, 2008, the system of paid use of plastic shopping bags has been implemented in all supermarkets, shopping malls, bazaars and other commodity retail places, and plastic shopping bags shall not be provided free of charge. Plastic bags play an indispensable role in our lives, and our country consumes a lot of plastic bags every year. In my country, 1 billion plastic bags are used every day to buy vegetables, and more than 2 billion plastic bags are used every day. It has long been a habit in our life to go to supermarkets and markets for shopping with plastic bags provided by merchants. However, while plastic bags provide convenience for consumers, they also cause serious waste of energy resources and environmental pollution due to excessive use and difficulty in recycling. In particular, ultra-thin plastic bags are easily damaged, coupled with the weak awareness of environmental protection of the Chinese people, most of them are discarded at will after use, scattered in urban streets, tourist areas, water bodies, and on both sides of roads and railways, causing "visual pollution" and becoming a The main source of "white pollution". More and more countries and regions have restricted the production, sale and use of plastic shopping bags. As soon as my country's plastic restriction order comes out, it means that our living habits will inevitably change, and we will return to the life of shopping with a basket of vegetables. So many opinions and remarks aroused. Some of them may be accustomed to the convenience brought by plastic bags in their lives, ignoring the harm it causes and hold objections. The plastic bag was invented on October 24, 1902 by the Austrian scientist Max Schuchny. Lightweight and sturdy, the packaging is loved by customers and merchants alike. Therefore, shops and vegetable markets have provided free plastic bags. But 100 years later, this invention has given us serious environmental problems. Because most plastic bags are produced with non-renewable degradable materials, the plastic structure is stable, not easily degraded by natural microorganisms, and will not be separated for a long time in the natural environment. The only way to deal with these white wastes is to dig into landfill or incinerate at high temperature. Both of these methods are not conducive to environmental protection. The landfill of waste plastics will not only occupy a large amount of land, but the occupied land will not be restored for a long time. The plastic bags buried in the ground will take more than 200 years to rot, which is extremely harmful to the land and will change the pH of the land. , seriously pollute the soil, affect the absorption of nutrients and water by crops, reduce agricultural production, and affect the sustainable use of land. The harmful smoke and toxic gases produced by incineration will also cause pollution to the atmospheric environment. Therefore, plastic bags have become the "worst invention" of mankind in the 20th century. The implementation of the plastic restriction order is precisely to solve or alleviate a series of environmental problems caused by the excessive use of plastic bags. From June 1, 2008, everything will be different. The production, sale and use of plastic bags with a thickness of less than 0.025 mm, that is, ultra-thin plastic bags will be prohibited. In order to improve the service life of plastic bags, make people use plastic bags rationally and economically to reduce pollution. All supermarkets, shopping malls, bazaars and other commodity retail places will no longer provide free plastic bags. Consumers are encouraged to pick up cloth bags again, pick up vegetable baskets with heavy pay, and reuse durable shopping bags to reduce the use of plastic bags. Environmental protection is not a matter of one person or two, but a matter of everyone, the country, and future generations. It requires the participation of the whole society. We only have one earth, and from a sustainable development perspective, the plastic restriction will be a measure that benefits future generations. Maybe in the near future, plastic bags will disappear from our lives. It is everyone's responsibility to take care of the environment! Let us free ourselves from the imprisonment of using plastic bags! The recycling value of plastic bags is low, and most of them enter the environment for recycling. There are two main hazards to the environment, namely "visual pollution" and "" Potential Hazard". Visual pollution refers to the damage to city appearance and landscape caused by waste plastic products scattered in the environment. Waste plastics scattered in big cities, tourist areas, water bodies, and railways bring bad stimulation to people's vision and affect the overall aesthetics of cities and scenic spots. And damage the image of our country and people. We call this situation "visual pollution". Visual pollution is the most prominent hazard of the "white pollution" problem. Visual pollution of waste plastic waste that exists to varying degrees in cities, tourist areas, water bodies, and both sides of roads and railways in my country. These waste plastics are scattered on the ground, or hang on the branches in the wind, or float on the water surface, causing pollution. The environment, the spread of diseases, and the people reacted strongly to this. Potential hazards refer to the long-term deep-seated environmental problems caused by waste plastic products being difficult to degrade after entering the natural environment. The plastic structure is stable, not easy to be destroyed by natural microorganisms, and will not be separated for a long time in the natural environment. This means that if plastic waste is not recycled, it will become a pollutant in the environment that will exist permanently and accumulate. The hazards in the environment have the following aspects: Affect the development of industrial and agricultural production. The plastic products floating in the Yangtze River have brought great difficulties to the water source, causing pump evacuation and blockage, causing huge losses to industrial production and hydropower stations. For example, the Gezhouba Hydropower Station loses 200,000 KW.H of power every day due to the cleaning of floating plastic waste. In the future, after the completion of the Three Gorges Hydropower Station on the Yangtze River, if plastic waste continues to pollute the water body, the loss of power generation will be unimaginable; in zoos, pastoral areas, rural areas, and oceans, such situations are not uncommon; It is difficult to recycle the waste plastic products that enter the domestic garbage. If it is landfilled, it will not degrade for 200 years, which will lead to a long-term occupation of large areas of land, aggravating the pressure on land resources. Not only will our generation be surrounded by garbage, but also future generations will lose their living space; it will affect the comprehensive utilization of garbage. Domestic waste mixed with plastic is not suitable for composting, and waste plastics must be sorted out from the garbage, which increases the cost of composting. The quality of polluted waste plastics cannot be guaranteed, and its utilization value is also very low; the random discarded plastic waste increases the work intensity and pressure of the environmental sanitation department; plastic waste is also easy to carry bacteria and spread diseases.
