I knew this video, it's great. It does points out some important aspects in design, but it should also point out that we are in part responsible for the consumption, always after the latest model, just because it's cool. Here in Brazil cell phones are like that, people upgrade just because of some new feature (or because the phone companies offer upgrades so cheap they can't resist!). A colleague has just bought a new one because his didn't have an MP3 player and now he only needs to carry one thing. It makes sense, but then it's not a sustainable posture.
National Geographic Magazine had an article months ago about the "recycling" of electronic components in Africa (exactly what they say about at around 4:00 in the video). It is shocking.
To be really "green" requires a change of attitude, of life standards even. And the whole product life must be considered.
