What Are the Advantages and Disadvantages of Mining?

Mining allows humans to use these resources. Some mining practices are controversial. Mountaintop-removal mining for example allows mining companies to extract a significant amount of coal at a far lower cost but its destructiveness has led to protections for the environment. Traditional forms of mining can be unsafe for workers.
