No one’s found a patch of solid gold to carve out like a pumpkin. Once
raw material is removed, it needs to be processed, which involves
massive amounts of heavy metals like mercury, along with large
quantities of water. While gold mines are supposed to contain, clean and
control their waste, many don’t, leading to contamination of water
supplies with arsenic, mercury and cyanide. Those metals threaten
community health, harm crops and wreak havoc on the natural environment,
which is already disturbed thanks to the passage of heavy trucks,
destruction of habitat and other by-blows of gold mining.
