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, as well as the disruption of water supplies and the erosion of soil.

Water pollution is caused by the release of mining waste into water bodies. This can contaminate drinking water, harm aquatic life, and make it difficult for people to use rivers and streams 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 also lead to the erosion of 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 mines, and can also contribute to climate change.

All of these environmental impacts can have a significant negative impact on the people and environment of Manipur. It is important to take steps to mitigate these impacts, such as by planting trees to replace those that are cut down, treating water before it is released into rivers and streams, and restoring land that has been damaged by mining.
