What are the disadvatages of mining and quarrying?

There are risks associated with all mining operations. People can be injured or killed mining. These risks must be well managed, but cannot be completely avoided. But the "big picture" as regards mining is usually one that has environmental impact as its focus. Mines, particularly the large open pit or strip mines, can scar the land and heavily impact the environment. The material processing facilities also threaten the environment. Having said that, environmental concerns make up much of the down side of mining and quarrying.
