Missed these the first time round, so thanks to Olivier for pointing them out again.
What I can't work out is whether they are a clever, ironic statement on the laissez faire attitude most of us have towards the future of our planet. Or whether they are displaying a stupidly laissez faire attitude to the future of our planet.
Or whether that confusion is the whole point. In which case they are probably a little to clever for my simple brain!
