5 Major consequences of coal mining

Coal is still the most prevalent energy source in the entire world and the United States is not an exception. Almost 91 percent of the country’s electricity is generated in coal-burning plants. Still, coal mining is a nefarious activity for the environment and for the human health. In fact, the industry is responsible for one-third of all carbon emissions registered in the United States.
