Hint
Think about which 'R' focuses on minimizing the consumption of resources like electricity and water.
Quick Oral Answer
Switching off unnecessary appliances and fixing leaking taps falls under 'Reduce' because it minimizes the consumption of resources.
Analysis & Explanation
The concept of the 5R's stands for Refuse, Reduce, Reuse, Repurpose, and Recycle.
- Reduce means to use less of a resource to prevent waste.
- Switching off unnecessary lights and fans directly reduces the consumption of electrical energy.
- Repairing leaking taps reduces the wastage of water.
- Therefore, these actions perfectly define the term Reduce.
Why other options are incorrect:
- Recycle (Option A): Refers to processing waste materials to make new products.
- Reuse (Option B): Refers to using things again and again instead of throwing them away.
- Repurpose (Option C): Refers to using a discarded item for a different useful purpose.
Common Mistakes
- 1Confusing 'Reduce' with 'Reuse' or 'Recycle'. Remember that saving resources at the source is always 'Reducing'.
Interesting Facts
Reducing consumption is considered the most effective of the 5R's because it prevents waste from being generated in the first place.
