Why Mineral Conservation is Essential:
Minerals are finite and non-renewable. The total volume of workable mineral deposits is only about one per cent of the earth's crust. Geological processes of formation take millions of years, while the rate of replenishment is infinitely small compared to the present rate of consumption. Continued extraction leads to increasing costs and decreasing quality of ores as mining moves to greater depths. Thus, rich mineral deposits are valuable but short-lived possessions.
Strategies for Sustainable Use:
- Use mineral resources in a planned manner to avoid wasteful extraction.
- Develop improved technologies to allow use of low-grade ores at low costs.
- Recycling of metals and use of scrap metals to reduce demand for fresh mining.
- Use substitutes wherever possible to reduce dependence on scarce minerals.

Explanation
- The question is 5 marks, so examiners expect both why (reasons for conservation) and how (strategies) — cover both halves.
- Quote key phrases from the textbook: "one per cent of the earth's crust," "infinitely small rate of replenishment," "finite and non-renewable" — these fetch marks.
- The three strategies (improved technology, recycling/scrap metals, substitutes) are directly from the passage — don't skip any.
- Avoid padding with general points not in the textbook passage.
