We need to start seeding the next civilisation, because this one is finished
Summary: This civilisation (meaning: the vast majority now of human life on Earth) will be transformed:
It will either collapse utterly.
Or it (we) will manage to seed a future successor-civilisation, as this one collapses.
Or this civilisation will somehow manage to transform itself radically and rapidly, in an unprecedented manner, in time to avert collapse.
