"Strip mining" is the practice of mining mineral by removing the earth below and digging out the mineral.
In North America, this method is still commonly used to mine coal.
This type of mining uses some of the biggest machines on Earth to scrape the mountain, sometimes even removing a mountaintop to get to the desired mineral.
This method is terrible for the environment and leaves an ugly scar on the Earth's surface.
I love this photo shot in October 1973. It comes with this description, "There is some local opposition to stripping the land in Southeastern Ohio. Most people, however, are employed by the coal companies and are afraid any demands for reform will cost them their jobs."
