Mining for gold, silver, diamonds, gemstones, and other metals can
result in water pollution, greenhouse gas emission, and soil erosion.
Dr. Doug Guthrie, dean of International Business and Management at
the George Washington University School of Business, and a team of
researchers compiled a report in 2010, titled “The Environmental Impact of Mining Precious Metals and Gemstones: The Case for Putting Jewelry Back Into Circulation.”
Guthrie explored the use of toxic chemicals in mining. Cyanide is
used to separate gold from ore, for example. His report states that 20
tons of waste are produced for every ounce of gold. An average
large-scale gold mine uses 1,900 tons of cyanide annually. Arsenic and
other chemicals are used in mining other materials.
