"Thank you, Bryan Appleyard, for a clear, if chilling (no pun intended) outline of the issues that confront us, though in an otherwise excellent summary I would say a bit more than a tilt to Prof Lovelock's thoughts on the issue of population could have been worth factoring into those Sandalesque restorative or Nukist techno-solutions. People are consumers. Consumers cause pollution. Pollution causes climate change (or at least doesn't help much). Climate change reduces still further the ability of the planet to sustain life. Ergo..?
So 'we' need to change. But one additional problem I might suggest is the fact that there is a rather large, and still somewhat disenfranchised collection of folk (to which we happily claim membership, and have deemed our light green PALs, for 'public at large'). We see ourselves caught in an uncomfortable no man's land watching the mighty artillery exchanges of Green Elite Nukes and Sandals (plus a few from the 'not-us, too-late, I'd like to stay elected or next-generation-to-miners' getting thrown in) sailing overhead, and are pretty much stuck where we are while all this rages around us.
