Efforts to save civilization may be noble, while still with it continuing there is more destruction and ruining this world. It might not continue so long, but many people, if they leave cities and anything of civilization to live on land in small groups growing all they can there to subsist that way separately, would continue on, while civilization will not go on past the catastrophic disasters. It could not last forever in this limited world as it gets ruined with the demands that always will come with civilization. The technology that ruins this world cannot be what can save it.
