Limestone mining can pollute water and create sinkholes. When limestone dissolves while it''s still in the ground, caves and gullies form, a natural phenomenon known as karst. Although this doesn''t hurt the environment in its natural form, once the limestone is mined out, sinkholes can form and disrupt underground waterways.
