Explain the importance of conservation of minerals. Highlight any three measures to conserve them. (CBSE 2016)
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 and it is non-renewable.
Four ways 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.
4. Scrap metals and substitutes must be used rather than continued mining of ores.
Explanation: Use of minerals is an essential and irreplaceable feature for development in any country. But if not used judiciously, it may exhaust soon.
