Gold mining has been a major environmental challenge in Peru, with illegal operations causing deforestation and polluting rivers with chemicals.
The industry continues to grow, with miners expanding into new areas and adopting different methods, including river-based extraction.

The project is one of the first visualizations of Peru's mining problem on a national scale.
