Potential environmental impacts of mining in Manipur include:

Deforestation
Water pollution
Soil degradation
All of the above

The potential environmental impacts of mining in Manipur include deforestation, water pollution, soil degradation, and air pollution.

Deforestation is the removal of trees to make room for mining operations. This can lead to the loss of habitat for wildlife, the disruption of water supplies, and the increase of soil erosion.

Water pollution is caused by the release of mining waste into water bodies. This can contaminate drinking water, harm fish and other aquatic life, and make it difficult for people to use the water for recreation.

Soil degradation is caused by the removal of topsoil during mining operations. This can make it difficult for plants to grow, and can lead to the loss of nutrients in the soil.

Air pollution is caused by the release of dust and other pollutants into the air during mining operations. This can cause respiratory problems for people living near mining sites, and can contribute to climate change.

All of these environmental impacts can have a negative impact on the health and well-being of people living in Manipur. It is important to take steps to mitigate these impacts, such as planting trees to replace those that are cut down, treating wastewater before it is released into water bodies, and covering exposed soil to prevent erosion.
