Dead Ringers: the Science Museum asks us the question "should we upgrade our mobile phone?" "No" and "no" say the Times and the Observer, but we still do: on average every 18 months. What's the problem? Well it isn't just the lead, arsenic, beryllium and brominated fire-retardant cases (pollutants all) disappearing into our land fills (which are not covered by the Waste Electrical and Electronic Equipment Directive [WEEE] in Europe). Coltan also goes into our phones. It occurs mainly in the Democratic Republic of Congo, and as such our demand for upgrades has been contributing to a war (despite mobile phone companies' claims to the contrary, coltan is not regulated like timber). If we must upgrade, we can at least recycle or hack our old phones.
Before you get that cell phone check to see where the tantalum inside it comes from. You could be funding a civil war in the Congo.
