We’ve had Blood Diamonds , so perhaps next it will be Blood Minerals and Blood Phones. Huh? Simply that many of the mobile devices that we can’t seem to live without nowadays contain minerals, some of which come from countries run by people that are a bit nasty. For example, that new smart phone you’re walking about with might contain tantalum that fuels conflict in the Congo. Tungsten, cobalt and gold could perhaps be added to the list of suspect substances.
