प्रश्न
Why should biodegradable and non-biodegradable wastes be discarded in two separate dustbins?
उत्तर
Biodegradable waste and non-biodegradable waste should be discarded separately into different dustbins so that they can be recycled accordingly. Biodegradable waste changes to manure naturally. Non-biodegradable waste, on the other hand, is recycled into new products.
