George Monbiot has just the thing for a depressed, ill-at-ease, fearful and slightly paranoid person such as myself to contemplate. You have never had it so good, and guess what? You never will again. It's all downhill from here. In fact, on some scales, it's been all downhill since 1976. Think of that - 5 million years of steady progress and just as we, the human race, become sophisticated enough to measure it, it passes the peak and starts on the short slippery slope down. All I can say is, I hope this is just liberal PC scaremongering, because frankly it hardly bears thinking about.
