Identify two negative social impacts, other than air or water pollution, that may affect a local community during the active mining phase.

Evaluate how the opening of a large-scale mine can lead to both improved local infrastructure and a simultaneous decline in air quality for a neighboring community.

A rural community is situated 5 km downstream from a proposed large-scale open-pit copper mine. The area is currently used for subsistence farming and is located near a primary river system that provides water for both irrigation and domestic use.

(a) Discuss how the management of mining waste (tailings) and overburden could lead to water pollution in the local river system.
(b) Explain the potential social impacts on the community regarding their health and local economy during the mine's operation.
(c) A critic of the project suggests that the visual pollution and noise pollution will permanently damage the area's potential for future ecotourism. Evaluate this claim by suggesting one way the mining company could minimize these specific impacts during the extraction phase.
