Model answer & approach
- Mineral resources are fundamental to the country's economy and these are exploited by mining. Why is mining considered an environmental hazard ? Explain the remedial measures required to reduce the environmental hazard due to mining. (Answer in 250 words)
Introduction
Mineral resources are vital for industrial growth, infrastructure, and energy security, but unregulated mining has emerged as a major environmental hazard in India. It causes degradation of land, air, and water, affecting ecosystems and local communities.
Body
1. Environmental Hazards of Mining:
- Land Degradation: Open-cast mining leads to deforestation, soil erosion, and loss of agricultural land.
- Water Pollution: Discharge of mine effluents and acid mine drainage contaminates rivers and groundwater (e.g., coalfields of Jharkhand and iron ore mines of Goa).
- Air Pollution: Drilling and blasting release dust and particulate matter, affecting air quality and human health.
- Biodiversity Loss: Mining in ecologically sensitive zones disturbs wildlife habitats, as seen in parts of the Western Ghats.
- Socio-Economic Impact: Displacement of local and tribal populations and decline in traditional livelihoods.
2. Remedial Measures:
- Strict Regulation: Enforce compliance with Environmental Impact Assessment (EIA) and Mining Closure Plans.
- Reclamation and Afforestation: Restore mined-out land through re-vegetation and soil rehabilitation.
- Waste Management: Promote eco-friendly technologies for waste reuse and tailings management.
- Water and Air Pollution Control: Use dust suppression systems and effluent treatment plants.
- Sustainable Mining Practices: Adopt National Mineral Policy (2019) and encourage mine auditing and community participation.
Conclusion
Mining, though economically indispensable, must transition to a sustainable and scientifically managed activity. Balancing resource extraction with environmental stewardship and social responsibility is crucial for long-term ecological and economic stability.
