Well, the Christians' have been doing it for 20 centuries on the basis of spiritual interpretation of religious texts.
The expectation that civilization will collapse nowadays comes from scientific knowledge based on verifiable data. We are witnessing:
- a massive decline in biodiversity
- a massive decline in biomass
- fragmentation of ecosystems
- collapse of ecosystems
These are already observable and documented facts. These by themselves present a real and urgent danger to our global human civilization. Then there are the probable consequences from the climate crisis:
- massive population migrations
- destabilization of countries and federations
- civil wars
- actual wars between countries in order to fight for resources (i.e. water).
We are headed for calamity. Let's not be delusional about that.
