The correct answer is: d) All of the above.
Illegal mining is a major challenge faced by the mining sector in Andhra Pradesh. It leads to loss of revenue, environmental damage, and social conflicts.
Loss of revenue: Illegal mining deprives the government of revenue that could be used to provide essential services to the people. It also leads to unfair competition for legal miners, who are forced to operate at a loss.
Environmental damage: Illegal mining can cause significant environmental damage, including deforestation, soil erosion, and water pollution. It can also lead to the extinction of endangered species.
Social conflicts: Illegal mining can often lead to social conflicts, as local communities compete for access to resources. It can also lead to violence and crime.
The government of Andhra Pradesh has taken some steps to address the problem of illegal mining, but it is a complex issue that is difficult to solve.
