George Monbiot of The Guardian has crafted an interesting piece on smartphones (and general electronics) that are constructed in the blood of people from the eastern Democratic Republic of the Congo. Gold, tantalum, tin and tungsten have been fought over by rival armies and militias for years. The war has killed millions through displacement, disease and malnutrition.
But which of the smartphone companies today are making sure their hardware is built using minerals that are gathered through legit and conflict-free? It's believed that Nokia has done more than most manufacturers with its Windows Phone and Asha line of products, but there's still room for improvement across the board, according to Monboit's report.
