उत्तर
- Reduce: Use fewer resources in the first place. Reducing product production, transportation, and disposal reduces the need for more resources.
- Reuse: Avoid discarding materials after each usage and reuse them in their original state. Reusing resources extends their usefulness and prevents old ones from ending up in landfills.
- Recycle: Waste materials are converted into new goods through physical and chemical processes. Recycling not only saves energy but also prevents the use of fresh resources and the disposal of outdated items.
