A highly responsible civilization that achieves space fairing tech could rebuild its environment, leaving a clean planet as a gift for future species to emerge, and move to the stars. Sort of artifical-creationism, but phycally achievable, it's a matter of civilization goals.

- TeMPOraL 6y agoTo give the next species a chance to grow? While a stretch as a motivation, the Uplift saga by David Brin has this as a core point: ecology and biodiversity is important for all the species in these books; planets are leased and used for a while, and then lain fallow to let them regrow and potentially spawn more sentient beings that could then (be helped to) join the galactic community.
