Plastic bags bring convenience to people's lives, but temporary convenience brings long-term harm.
The recovery value of plastic bags is low. In addition to the visual pollution caused by scattered on urban streets, tourist areas, water bodies, roads and railways, there are potential hazards. The plastic structure is stable, not easily degraded by natural microbial bacteria, 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 for a long time and accumulate, which will cause great harm to the environment.
According to statistics, 260 million tons of plastics are used worldwide each year, of which 170 million tons are disposable.
