How is limestone bad for the environment ...
Limestone mining causes widespread disturbance in the environment. Myriad impacts are observed as changes in land use pattern, habitat loss, higher noise levels, dust emissions and changes in aquifer regimes. A well-formulated Environment Management Plan will help in mitigating the impacts of mining on the environment.

Lime throughout history | Lhoist - Minerals and lime producer
Nobody knows exactly when humans first discovered lime. Perhaps ancient occupants of Earth used limestone rock to protect their fireplaces. Fire heated the rocks and the first burnt lime was created. It then rained and the lime slaked into calcium hydroxide, which reacted with the ashes and sand around the fireplace creating the first ancient mortar.

Calcite Mineral | Uses and Properties
Pulverized limestone is also used as a mine safety dust. This is a nonflammable dust that is sprayed onto the walls and roofs of underground coal mines to reduce the amount of coal dust in the air (which can be an explosion hazard). The mine safety dust adheres to the wall of the mine and immobilizes the coal dust.
