Disposable plastic bags have been widely used in modern life, and people's usage habits are quietly producing profound and long-term cumulative effects on the ecological environment.
First, the habit of discarding them at will has led to serious visual pollution. Disposable plastic bags are thin and light, and are easily blown by the wind. They can be seen everywhere in the city's streets, parks, rivers, etc. A large number of discarded plastic bags are hanging and entangled on branches and grass, or floating on the water, which seriously damages the beauty and coordination of the natural landscape, making the originally neat and beautiful environment messy, giving people a very poor visual experience, and also reducing the overall image and quality of cities and villages.
Secondly, the long-term and frequent use of disposable plastic bags and the lack of correct disposal methods have caused continuous harm to the soil and water bodies. Plastic bags are difficult to degrade naturally and may exist in the soil for decades or even hundreds of years. They will hinder the air permeability and water permeability of the soil, affect the growth of plant roots and nutrient absorption, and lead to reduced crop yields. On the one hand, plastic bags that are randomly discarded into the water may be eaten by aquatic animals, causing blockage of their digestive tracts or even death, destroying the food chain balance of the aquatic ecosystem; on the other hand, harmful substances in plastic bags may seep out during the soaking process in the water, polluting the water quality, affecting the living environment of aquatic plants and animals, and thus having a long-term negative impact on the health and stability of the entire aquatic ecosystem.
Furthermore, from the perspective of resources and energy, the excessive use of disposable plastic bags wastes a lot of resources and consumes a lot of energy. The production of plastic bags depends on non-renewable resources such as petroleum, and its production process also consumes a lot of energy for raw material refining, processing and manufacturing. However, since most of them are discarded after use instead of being effectively recycled, this not only causes a huge waste of resources, but also indirectly increases the energy consumption and environmental pressure caused by obtaining more resources. In the long run, it poses a serious threat to the sustainable use of global resources and energy.
Finally, people's dependence on disposable plastic bags has also hindered the promotion of environmental protection concepts and the implementation of environmental protection actions to a certain extent. When the use of disposable plastic bags becomes a habitual behavior, the public's attention and sense of responsibility for environmental protection will be weakened, which is not conducive to the research and development, promotion and popularization of other environmentally friendly alternatives. It also makes the entire society lack sufficient motivation and action to deal with the global environmental problem of plastic pollution, thereby further aggravating the long-term cumulative destructive effect of disposable plastic bags on the ecological environment.
