Alternate apocalypses

[headquarters]

It has happened from time to time you know.

Mediterranean civilizations exploding in volcanic fireblasts that creat tidal waves that drown everything after ,setting things back to a nigh on neolithic level

Plagues born by bugs that live on common rodenst that wipe out something liejk 50-90% of the population in a short time span -and the mass hysteria and ill adviced decision that spawns-the European plagues..

Resources dwindling/crops failing and states warring with eachother because of the harsh times -the South American civilizations -from astrology and towering ziggurats to being swallowed by the jungle and going back to substenance farming for hundreds of years

Upheaval and war ,internal /domestic dissarray causing massive migrations that press the borders of a major power until it collapses- the Western Roman Empire..

The lure of an empires wealth lead to border wars that burn out the tenacity and drain the power of a major power until it is overrun -the Chinese Han dynasties conquered by the Mongols

I am sure there have been random tidal waves and volcanic eruptions and asteroid strikes that have ended a few too .( like the destruction of Lisboa in the 1700s -although that didnt end the Portoguese outright).

What will end ours is hard to say - but at some point it will crash like the others have imho .

(Please note - I do not qualify what constitutes civilization here -I just state examples that ended some of the recognized ones-just thought I would add this caveat as there seems to be a little political simmering going on in this thread)
