It's Scott Pelley, in Kivu area (Eastern Province) of Congo. I lived there for several weeks, on Lake Kivu, in 1984, before going to Cameroon for my Peace Corps teaching job. The Enough Project director is talking about raw material mining and exploitation of civilian miners by warlords.

This is the land of soukous music, the best music on the planet. Poly-rhythms on electric guitars. I have lived there, I've been talking about gold mining, the environmental and social costs for a decade. I put a few thousand dollars into a "recycled gold" patent search. It's one of the things that attracted me to the electronics "e-waste" recycling business... not desire for the metal, but disgust at seeing it thrown away. It's like throwing away baby seal pelts.
