Question

What are the different ways of conserving minerals?

• A. Use of more non-renewable sources of energy
• B. Reuse and recycle the minerals and their products
• C. Use of biogas as a fuel for cooking
• D. Both B and C

Answer 1

The correct option is D

Both B and C

Minerals resources are limited. It takes million of years for their formation and therefore, these resources are non-renewable and non-replenishable. Increasing consumption and continued extraction of ores lead to increasing costs of extraction and a sharp decrease in their quality and quantity.
So, it is most important for us to conserve mineral resources as it is feared that with this rate of consumption the days is not far away when most of the metallic and non-metallic mineral reserves and fossil fuel deposits will be fully exhausted.
