Yes Robert another entirely pointless and very expensive talkfest at Rio which of course brings this song to mind:
Rather as I expected the Rio +20 summit on sustainable development has closed without advancing the practice of sustainable development by one jot, one title or one iota. The forests will shrink as they are plundered in developing countries, the seas will become deserts as they are shorn of life and filled with what billions of humans no longer need, and the greed of every interest group attending the summit set the scene: talk was cheap, the begging bowl was held out and commitment to anything was somewhere else. The only sustainable thing that has emerged from this Rio+ 20 summit is that there will be another summit in Rio again. That at least is self sustaining.
