Why is mining called a killer industry?
Mining is known as the killer industry due to following reasons:
It is dangerous for the health of miners who often have to work in unsafe conditions in underground mines. Frequent accidents occur in mines due to collapse of roofs and water flooding. These end up causing many casualties.
Miners are exposed to toxic materials causing disease of lung and reduced life expectancy. E.g. black lung caused by inhaling coal dust.
It has a negative effect on environment as volumes of hazardous garbage are produced during extraction of minerals from mines causing environmental degradation and water pollution.
Mining activities are a major cause of deforestation. A huge volume of earth is also excavated and displaced causing silting.
