Information
The environmentally-friendly decomposition method used today is relatively faster, and may decompose within a year. There are also faster, the Olympic environmental protection plastic bags can be decomposed 72 days after being discarded.
Plastic bags have indeed brought convenience to our lives, but the convenience at this time has brought long-term harm. Plastic bags have low recycling value. In the process of use, they are scattered in city streets, tourist areas, water bodies, roads and railways. In addition to the "visual pollution" pollution caused by the side, it also has potential hazards. The plastic has a stable structure, is not easily degraded by natural microorganisms, and does not separate in the natural environment for a long time. This means that if waste plastic waste is not recycled, it will become a pollutant in the environment that will permanently exist and continue to accumulate, which will cause great harm to the environment.
One, affects the development of agriculture. The continuous accumulation of waste plastic products mixed in the soil will affect the absorption of nutrients and water by crops, resulting in reduced crop yields.
Secondly, it poses a threat to the survival of animals. Waste plastic products discarded on land or in water bodies are swallowed as food by animals, leading to their deaths. Last year, there were 20 herders by the Qinghai Lake, a total of nearly 1,000 sheep died as a result, and the economic loss was about 300,000 yuan. Sheep like to eat the oily residue wrapped in plastic bags, but they often eat them together with the plastic bags. Because the plastic they eat stays in the stomach for a long time and is difficult to digest, the stomachs of these sheep are packed and can no longer eat. Things can only be starved to death in the end. Such things are not uncommon in zoos, pastoral areas, rural areas, and the ocean.
Third, waste plastics being buried with garbage will not only occupy a large amount of land, 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 that enter the domestic garbage are buried, they will not be degraded 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, not only will it affect the environment, but if passively swallowed, it will lead to death. This destroys the ecological balance.
Fourth, high temperature will decompose toxic substances, plastic products are non-toxic, but because of its recycling and reuse ² the equipment used is not perfect, the craftsmanship is simple, and many manufacturers do not have legal business licenses, resulting in plastic products that are reproduced at a high temperature. At 65°C, toxic substances will separate out and penetrate into the food, which will cause harm to important parts of the human body such as the liver, kidneys, reproductive system, and central nervous system.
