Firstly, watch this fascinating depiction of air traffic movement – it’s 24 hours condensed down to 2 minutes, so things move pretty quickly considering the distances involved. Each yellow dot is a large aircraft (so, it’s only a small chunk of the real air traffic up there at any time)…

Watching this reminded me of the shocking film I saw yesterday – I didn’t post it at first because it’s so grim. The film was Mother’s “Plane Stupid” demonstrating the fact that the average European flight produces 400kg of greenhouse gases for every passenger (which seems impossible and frightening at the same time) – the weight of a polar bear… I warn you now, this is not a pleasant film and the reactions on YouTube are pretty negative because it is so shocking.

Although searching for that, I stumbled across something else – from Ogilvy New York – a really sweet, arty piece that plays on similar grounds…
