THE CONVERSATION
The 16th-century King Ferdinand of Spain sent his subjects abroad with the command: “Get gold, humanely if possible, but at all hazards, get gold.” His statement rings true today. Gold remains one of the world’s most expensive substances, but mining it is one of the most environmentally and socially destructive processes on the planet.
Around 7% of the gold purchased globally each year is used for industry, technology or medicine. The rest winds up in bank vaults and jewellery shops.
Beautiful objects and stable investments are worthwhile things to create and own, and often have significant cultural value. But neither can justify gold mining’s staggering human and ecological toll. In a recent study, my colleagues and I showed how it might be possible to end mining and instead rely entirely on recycled gold.
Despite improvements in gold mining practices over the past century and new regulations designed to limit mining’s impacts, this industry continues to wreak havoc upon landscapes across every continent except Antarctica.
