Whoa. Think Twice About That Gold Jewelry, Folks

From an excellent NYT investigation reported in today's edition:

Consider a ring. For that one ounce of gold, miners dig up and haul away 30 tons of rock and sprinkle it with diluted cyanide, which separates the gold from the rock. Before they are through, miners at some of the largest mines move a half million tons of earth a day, pile it in mounds that can rival the Great Pyramids, and drizzle the ore with the poisonous solution for years.
