2023 - 2: Your Phone's Dirty Gold

Guillermo Galdos follows Brazilian federal police cracking down on illegal mining in protected Indigenous regions and the network of companies dealing in the precious metal. Officially Brazil exports a hundred tons of gold a year. But efforts by police, academics and non-governmental organisations reveal evidence that possibly almost half of Brazil's gold trade comes from an illegal source, raising serious concerns for tech companies using gold in their products.
