Mining damages health in many ways: Dust, chemical spills, harmful fumes, heavy metals and radiation can poison workers and cause life-long health problems as well as allergic reactions and other immediate problems. Heavy lifting and working with the body in awkward positions can lead to injuries to the arms, legs, and back.

Via the British Museum, a drawing (c. 1590-1600) of mining activity, showing the use of hand-tools to mine ore in an open mine (although note the tunnel in the upper right).. Once the ore was located, mining tended to follow the ore, assuming whatever shape the ore-formation was in. For ore deposits in veins, that typically means diggings shafts and galleries (or trenches, if …

Such is the case in Brazil, where iron mining removes exceptionally diverse plant communities entirely . In other cases, spatial coincidence between minerals and biodiversity may lead to less significant impacts, because either extraction is infeasible, biodiversity is unaffected by mining, or mining causes less damage than alternative land ...
