The resources of the earth are limited, so we should cherish and cherish these resources. Therefore, we should classify garbage and reuse these available resources. At home, remind everyone of garbage sorting, sell mineral water bottles, cans, waste paper, etc. together, reuse resources, make money, and put waste batteries, ink cartridges, etc. into non-recyclable trash cans. At school, we put reusable garbage and non-reusable garbage in two different garbage bins, one recyclable and the other non-recyclable. Study with classmates and discuss the methods of garbage classification. In the suburbs, we should use two bags to sort the garbage, and pick up the garbage we see and sort it. Only in this way can we become excellent young pioneers. So it's easy to classify. Everyone sorts garbage, and the earth becomes beautiful. We will see dense forests, clear lakes, blue sky and blue sea, and everyone will show a sweet smile.
