Q.2 (iv):- Why do we need to conserve mineral resources?
Mineral 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 day is not far away when most of the metallic and non-metallic mineral reserves and fossil fuel deposits will be fully exhausted.
