Question

The three R’s that will help us to conserve natural resources for long term use are:


A
Reduce, Regenerate, Recycle
loader
B
Recycle, Regenerate, Reuse
loader
C
Recycle, Regenerate, Renovate
loader
D
Reduce, Recycle, Reuse
loader

Solution

The correct option is D Reduce, Recycle, Reuse
To reduce the over exploitation of natural resources and to save environment, three strategies (3 R's) are followed namely Reduce, Recycle and Reuse.

 To ‘reduce’ is to use less. For example, we can save electricity by switching off lights and fans,when they are not in use.

In ‘recycling’ we collect plastic, paper, glass and metal items and recycle these materials to make required things instead of synthesising or extracting fresh plastic, paper, glass or metal.

 In the ‘reuse’ strategy, we simply use things again and again. For example, the plastic bottles in which we buy various food-items like jam or pickle can be used for storing things in the kitchen.
