Why is conservation of mineral resources essential? Explain any three methods to conserve them.

Conservation of minerals is essential because:

1. It is a finite resource as only one percent of the earth’s crust comprises of workable minerals.

2. It is non-renewable because the geological process that leads to its formation is much slower than the rate of consumption today.

Three methods to conserve minerals:

1. Use of mineral resources has to be planned to avoid over-exploitation and contribute to sustainable development.

2. Technology has to be improved in a way that low-grade ores can be used at lower costs.

3. Metals should be recycled and scrap metals and substitutes must be used.

Explanation: Use of minerals is an essential and irreplaceable feature for development in any country. But if not used judiciously, it may exhaust soon.
