George Monbiot: Rio 2012 ... It's a Make-or-Break Summit. Just Like They Told Us at Rio 1992

George Monbiot is the author of the bestselling books The Age of Consent: A Manifesto for a New World Order and Captive State: The Corporate Takeover of Britain.

Worn down by hope. That's the predicament of those who have sought to defend the earth's living systems. Every time governments meet to discuss the environmental crisis, we are told that this is the "make or break summit", on which the future of the world depends. The talks might have failed before, but this time the light of reason will descend upon the world.

We know it's rubbish, but we allow our hopes to be raised, only to witness 190 nations arguing through the night over the use of the subjunctive in paragraph 286. We know that at the end of this process the UN secretary general, whose job obliges him to talk nonsense in an impressive number of languages, will explain that the unresolved issues (namely all of them) will be settled at next year's summit. Yet still we hope for something better.

This week's earth summit in Rio de Janeiro is a ghost of the glad, confident meeting 20 years ago. By now, the leaders who gathered in the same city in 1992 told us, the world's environmental problems were to have been solved. But all they have generated is more meetings, which will continue until the delegates, surrounded by rising waters, have eaten the last rare dove, exquisitely presented with an olive leaf roulade. The biosphere that world leaders promised to protect is in a far worse state than it was 20 years ago. Is it not time to recognise that they have failed?..
