However, we also need to realize that trash cans cannot completely solve the garbage problem. We all need to start from ourselves, raise environmental awareness, reduce the generation of garbage, and correctly classify and dispose of garbage. Only in this way can we truly achieve environmental protection and protect our common home on Earth.

The trash can is also a guardian of environmental protection and an important weapon for us to fight against environmental pollution. By sorting and disposing of garbage, we can separate recyclable materials, hazardous waste, etc. for easy subsequent recycling and treatment. This can not only reduce the consumption of natural resources, but also reduce environmental pollution and achieve sustainable utilization of resources.
