- Explain the remedial measures.
The Conclusion: Mining is crucial, and it should be regulated.
The Introduction:
Mineral resources are naturally occurring substances found in the earth that can be extracted and processed for economic gain. These include metals like gold, silver, and copper, as well as non-metallic minerals like coal, limestone, and salt. The extraction and processing of these resources provide raw materials for various industries and are crucial for the development of infrastructure and technology.
The Body:
Mineral resources are essential for several reasons:
1. Economic Growth
2. Industrial Development
3. Infrastructure Development
4. Energy Production
Mining is essential for accessing mineral resources critical to economic growth, but it is widely considered an environmental hazard due to its severe impacts on ecosystems, land, water, and human health.
Environmental hazards of mining:
1. Atmosphere: Dust, particulate matter, and pollutants emitted from mining degrade air quality and contribute to respiratory health problems in nearly communities.
-
- The mining industry contributes about 4-7% of global greenhouse gas emissions, releasing carbon dioxide (CO2), methane (CH4), and other greenhouse gases.
2. Lithosphere: Mining activities strip away vegetation and topsoil, causing erosion, deforestation, and loss of biodiversity.
-
- It causes contamination of soil from toxic heavy metals and chemicals, which negatively affects plant growth and soil quality.
3. Hydrosphere: Toxic chemicals such as mercury, cyanide, and heavy metals released during mining contaminate surface and groundwater, leading to acid mine drainage and posing risks to aquatic life and community health.
-
- Waste chemical runoff and sedimentation from mining pollute rivers, lakes, and groundwater.
4. Biosphere: Mining disrupts habitats and endangers species, affecting ecological balance and increasing the risk of extinction for endemic flora and fauna.
-
- Mining activities disrupt food webs and ecosystem functions, reducing the resilience of biological communities.
Remedial measures to reduce environmental hazards:
-
- Strict environmental regulations: Governments should enforce comprehensive mining regulations, including pollution controls, waste management, and rehabilitation requirements.
- Land rehabilitations: Restoration of mined areas by refilling pits, replanting native vegetation, and reconstructing natural habitats is vital.
- Water management and treatment: Adoption of water recycling, proper containment of contaminated run-off, and advanced water treatment technologies can limit water pollution.
- Cleaner mining technologies: Use of less invasive mining methods, reduction of hazardous chemicals, and adoption of sustainable extraction technologies like bioleaching help mitigate environmental damage.
- Continuous monitoring and community engagement: Regular environmental monitoring, transparent reporting, and active involvement of local communities in mining decisions drive accountability and responsible practices.
- Biodiversity conservation: Implementation of conservation plans and protection of critical habitats can help preserve ecosystem integrity.
The Conclusion:
Mining’s economic importance is undeniable, yet its environmental hazards demand urgent attention. Through strict regulation, technological innovation, effective restoration, and community involvement, the negative impacts can be minimized, ensuring resource utilization while safeguarding ecological and human well-being.
