Here is an issue I was unaware of until a thread appeared on the anthro-l mailing list, coltan mining in the Congo. Coltan is a mineral that is refined into tantalum which in turn is used in the manufacture of capacitors and other hi-tech products. The mining of this mineral has caused rather severe environmental and social issues and plays an important role in the financing of the African civil wars. We all too often assume that our electronic existence is clean because it doesn't appear to emit pollution and too easily forget or ignore what makes it all possible.
