As an aside, whilst the Sun remains main sequence, life will be
extremely resilient. Anyone who's tried to keep a patio free of weeds or
has seen an abandoned airfield or road will know how it doesn't take
long for life to reclaim even tough surfaces like asphalt.

Remember the film, "The Day After"? Had those events come to pass in
1983, by now the ruins of Kansas City would be well overgrown.

The thing is, it'd be nice to keep ourselves in a situation where we can
continue to enjoy the high standard of living we do now - and that will
require change of some sort.
