How mining is a cause of disaster?

In no particular order... Thermonuclear activity on the center of the earth. Moving of earth's plate. Human exploration gone wrong. Plague. same answer more explained. natural disasters come from...

It may result in killing people, bad dust in the air and pollution

well, technically they ARE natural disasters, but the specific damage they cause is water/flood damage and wind damage

Most natural disasters can't be stopped. natural=mother earth. those happen without anybodys fault sometimes they just happen and there's nothing we can do to stop it.

Hurricanes, Tropical Storms, Floods.
