Environmental Impact of Mining 🌱
❌ Deforestation – Large areas of forests are cleared.
❌ Soil Erosion – Mining disrupts natural landforms.
❌ Water Pollution – Chemicals from mines contaminate rivers.
❌ Air Pollution – Dust & harmful gases affect nearby areas.
❌ Biodiversity Loss – Mining destroys wildlife habitats.
📌 Example: Illegal sand mining in India affects river ecosystems and groundwater levels.
Sustainable Mining Practices 🌍
✔ Reforestation – Planting trees after mining.
✔ Eco-Friendly Technology – Using environment-safe equipment.
✔ Recycling Minerals – Reducing dependence on new extraction.
✔ Strict Regulations – Implementing environmental laws.
✔ Mine Closure Plans – Restoring land after mining stops.
📌 Fact: Sweden has strict environmental laws for sustainable mining.
Government Initiatives for Mining (India) 🇮🇳
| Scheme/Policy | Objective |
|---|---|
| National Mineral Policy (2019) | Sustainable mining & environmental protection |
| Mines & Minerals (Development & Regulation) Act (1957) | Regulates mining activities |
| Coal India Ltd (CIL) | Largest coal mining company in India |
| District Mineral Foundation (DMF) | Funds for mining-affected communities |
📌 Fact: The Indian government auctioned coal blocks for private mining in 2020.
