The mining industry has had a devastating impact on ecosystems worldwide. Is there any hope in sight?
A global campaign to boycott what activists are calling “dirty gold” gained its 100th official follower three days before Valentine’s Day.
The pledge was launched in 2004 by the environmental group Earthworks, which has asked retail companies not to carry gold that was produced through environmentally and socially destructive mining practices. Eight of the ten largest jewelry retailers in the United States have now made the pledge, including Tiffany & Co., Target and Helzberg Diamonds. The No Dirty Gold campaign is anchored in its “golden rules,” a set of criteria encouraging the metal mining industry to respect human rights and the natural environment.
While the list of retailers aligned in their opposition to dirty gold continues to grow longer, most gold remains quite filthy. The majority of the world’s gold is extracted from open pit mines, where huge volumes of earth are scoured away and processed for trace elements. Earthworks estimates that, to produce enough raw gold to make a single ring, 20 tons of rock and soil are dislodged and discarded.
Much of this waste carries with it mercury and cyanide, which are used to extract the gold from the rock. The resulting erosion clogs streams and rivers and can eventually taint marine ecosystems far downstream of the mine site.
