2. Reduce environmental pollution: waste batteries contain toxic substances such as mercury and cadmium, which will cause serious harm to human body; Waste plastics in soil will lead to crop yield reduction; Waste plastics are eaten by animals by mistake, resulting in accidents of animal death. So recycling can reduce the harm. ?
3. Turning waste into treasure: China uses 4 billion plastic snack boxes and 500-700 million instant noodle bowls every year, and waste plastic accounts for 4-7% of domestic garbage. 1 ton of waste plastics can recover 600kg of diesel oil. Recycling 1500 tons of waste paper can avoid cutting down trees used to produce 1200 tons of paper. A ton of cans can be melted to form a ton of good aluminum blocks, and 20 tons of aluminum ore can be mined less. 30%-40% of the production waste can be recycled, so we should cherish this small-scale and large-scale resource. You can also use cans as pencil boxes, which is environmentally friendly and saves resources.

Admittedly, our country has not done enough in this respect, and we should learn advanced garbage disposal methods from Japan.
