Illegal or unregulated mining can lead to:

Environmental degradation
Loss of revenue for the state
Social conflicts
All of the above

The correct answer is d) All of the above.

Illegal or unregulated mining can lead to a number of negative consequences, including:

  • Environmental degradation: Mining can damage the environment in a number of ways, including deforestation, soil erosion, and water pollution.
  • Loss of revenue for the state: When mining is done illegally, the government does not collect taxes or royalties on the profits. This can lead to a loss of revenue that could be used to fund important public services.
  • Social conflicts: Mining can also lead to social conflicts, as communities may compete for access to land and resources. In some cases, mining can also lead to violence.

It is important to note that these are just some of the potential consequences of illegal or unregulated mining. The specific impacts will vary depending on the location and type of mining activity.
