advantages and disadvantages - The Only Good Metal~Copper

Some environmental consequences of copper mining includes erosion, sinkholes, loss of biodiversity, and soil. A disadvantage of copper is that it costs a lot of money because it takes a lot of energy to dig the ore and to extract copper. Another disadvantage is that it is non-renewable because it can't be grown or produced.
