Eco Trip: Episode 3 - Gold Ring
In this episode, David uncovers some disturbing consequences of mining and refining gold for jewelry. Producing a single gold ring generates 20 tons of mine waste, and the release of dangerous mercury vapor in the air and sulfuric acid in ground water. In response, many jewelers are trying to distance themselves from "dirty gold" or looking into recycling options.
