Observing 4 ‘R’s — Flashcards

Answer

The 4 R's are Reduce, Re-use, Recycle, and Recover. They are ways of using materials carefully so that waste is reduced and resources are saved.

Answer

The 4 R's are important because human activities have increased waste and reduced natural resources. Using the 4 R's helps control environmental degradation and protects the environment.

Answer

The increasing population and changing lifestyle have raised the consumption of materials and resources. This has also increased waste generation.

Answer

Reduce means using fewer materials and creating less waste. It is the first step in caring for resources because preventing waste is better than managing it later.

Answer

Re-use means using an item again instead of throwing it away after one use. For example, a clean container can be used again for storage.

Answer

Recycle means processing waste material so that it can be used again in a new form. Plastic cans, bottles, and bags are recyclable materials.

Answer

Recover means getting value from waste materials so that resources are not completely lost. It is one of the four groups used to classify materials in this activity.

Answer

Personal materials should be segregated into four groups: Reduce, Reuse, Recycle, and Recover. This helps identify what can be saved, used again, or processed later.
