Mining is the removal of minerals and metals from the earth (Het Rapport 2009). These minerals are found in the ore bodies, veins, or coal seams. Mining happens in all over the world today. Some of the valuable minerals that can be mined are coal, copper, silver, iron, gold, and diamonds (Mining 06/15/07). Mining is important to surviving today but is also hazardous to the earth (Miller 2001). Many people have issues with mining because of its impact on our environment.

Researchers today will argue about the different types of mining. There are seven different types of mining that I have found to be accurate. All of them have unique environmental impacts (Mining 06/15/07). The “open pit mining” is commonly used to extract “hard rock” from ores such as metal ores, copper, gold, iron, and commonly coal (06/15/07). It has the most severe effect on the environment because the removal of land destroys the habitat of many different animals which causes them to relocate or become endangered (06/15/07). In addition, when the mine is no longer in operation, the area can no longer be used for anything else.

Deep-sea Mining is when mining involves extraction of minerals from the seabed (06/15/07). A commonly used method in deep-sea mining is dredging. Dredge is used to scrape the minerals off the seabed (06/15/07). This type of mining can easily disturb the aquatic ecosystems. Hazardous elements are released from the sediments into the water (06/15/07). Because Deep-sea mining is relatively a new method of mining the long-term effects on the environment remains unknown (06/15/07).

The main environmental effects unique to coal mining are the methane gases released (06/15/07). This causes the greenhouse effect. Coal mining is a massive industry and it provides jobs and a source of income to many families. Coal mining is also very harmful to the environment. Methane; which is released during coal mining, is the leading contributor to global warming...
