I just finished watching Robert Newman's History of Oil. It's quite scary watching; summed up, we're pretty much screwed. The Guardian Podcast interview with him is pretty good and sums up a lot of the points. The show was on More4, keep looking for reruns.
I may now be an anarchist anti-capitalist eco-warrior... If you own a car, fly short haul, work for The Man, shop in Tescos, use disposeable nappies or vote Labour, look out!
