Mining has a great effect on the quality of the air. Since mines need to blast through rock to get to an ore, dust may be produced in the process. Coal mines release methane, which contributes to environmental issues because it is a greenhouse gas.
Trees need to be cut down in order to have a mine built, and whole forests could be destroyed. Mining involves moving large quantities of rock, and in surface mining, overburden land impacts are immense.
Mines are highly damaging to the ecosystems surrounding them. Many different types of mines affect many different types of ecosystems. For example, deep-sea mines are at high risk of eliminating rare and potentially valuable organisms. Mining destroys animal habitats and ecosystems.
