Question

To which of the following does the 4R principle apply the most?

• A. Organic garbage
• B. Natural fibres
• C. Manures
• D. Plastics

Answer 1

Answer: (D)

Plastic is a man-made substance that cannot be broken down by natural microbial action. Hence, the 4R principle applies to it.

The 4 R principle is- $\text{Refuse, Reduce, Reuse and Recycle}$. This helps in reducing the harmful effect of plastic on the environment.
