Life, But Not As We Know It, Jim?

There is currently (and probably never will be), any possibility of moving substantial numbers of folk off 'spaceship, Earth'. If climate change got really bad, what are the possibilities of alternatively creating 'a spaceship-on-Earth'? Poorer people are likely to be left to suffer the consequences of global heating. There are many technological devices that could be used by rich folk, in wealthier countries. People could be housed in insulated, air-conditioned pods. Electricity production presumably would be ensured. These pods could be supplied with food, largely using hydroponics (climate change will have decimated much of agriculture). The hydroponics would have to use human waste from the pods, to continue producing foods. Human residents would largely remain in their pods (their health could be routinuely monitored, using 'smart toilets' etc). Entertainment/education could both be provided. These are likely, however, to consist largely of pre-recorded material and/or VR. Some individuals would be able to occassionally leave the pods, at auspicious times, in protective suits and/or vehicles. It's hoped (although nothing's certain) that there would be no millitaristic activity (although, the poor are unlikely to approve of the behaviour of their rich counterparts). I really don't like the sound of much of this! Surely, it's much better to maintain a liveable planet for as long as possible? Even the rich (major causal agents of climate change), must admit this?
