It's hard to know how to respond, Andrew. I agree with everything you say but the sticking point is public cognitive dissonance. Most people I know - friends, family, acquaintances - are aware of the climate crisis and other aspects of planetary overshoot, and many of them claim to be 'green'. But any mention of the climate crisis results in an almost audible grinding of mental gears as they hunt for a less emotionally inconvenient topic of conversation. Even such relatively easy choices such as ditching holiday flying seems a step too far - especially when hardly anyone else is making any sacrifices.

It seems to me that we face a challenge that is ultimately not structural or technical but moral. The issue of safety nets, degrowth, and social justice are paramount; yet our culture still regards poverty as the result of indolence while hero-worshipping the go-getter 'captains of industry', the billionaire classes. Voluntary frugality is an alien creed to most of us.

I'd suggest that we need to use the media to highlight that in a world with finite resources, the ultra-rich are in reality largely parasitic.

I don't hold out much hope that we can stave off disaster, but perhaps we can soften the blow a bit if we can encourage a new morality.
