During many periods in human history, some were doing just fine and others lived on the edge of starvation in a constant state of collapse.

The one unifying aspect of the present threat to human civilization is Catastrophic Climate Change, NOT lack of fossil fuel based energy.

I am absolutely certain that many jungle tribes in Brazil, Ecuador and Peru RIGHT NOW live on the edge of starvation in a constant state of collapse, while most of the city dwellers live not much better, but still avoid starvation.

My point in this quixotic exercise in hard truth logic is that the lack of food in the past has eventually triggered revolutions, not collapse of the civilization. LONG WARS of aggression are what have actually triggered collapse.

Catastrophic Climate Change is worse than a long war of aggression because it will last much longer than a human lifetime.

The climate change problem is intractable, but some WILL beat it for maybe a century or so. For example, there are places near the equator with very high mountains. A world heated plus 4 ° C by around 2060, despite happy talk by certain wishful thinkers, will kill off most humans. BUT, in high mountains, the tree line will move way up while the temperature becomes temperate, even at the Equator. I stress the equator, though RE will vigorously disagree, because human civilization in a low food environment with over acidified seas (no easy fish or whales or seals to catch = NO ESKIMOS) with poor available sunlight is not a recipe for long term survival, even if the temperature is mild enough to grow crops.

There is a mountain in Ecuador (Chimborazo) about 20,000 feet high that will, because of the horrendously altered atmosphere, get plenty of rain even at high altitudes. There are several other candidates in the HIGH tropics around the world. This will enable the folks living there to grow enough food, thanks to an ABUNDANCE of sunlight all year round, with low tech methods. They just might be able to ride out the fossil fuel burning stupidity that dooms most of human civilization.

ALL the people near the surface in the tropics will die as crispy critters, period. Those in temperate zones will perish too. Those near the poles who live near the surface will last as long as the food they have lasts. Unless they can maintain some geothermally heated and powered high tech greenhouse CITY that includes PLENTY of crop growing quality light and plenty of water, they will die too. I might add that those greenhouse giant domes had better be MASSIVELY strong. The storms that will visit them and the wind speeds they will face in a PLUS 4 ° C planet  will make any recent hurricane look like a gentle breeze.

STOP thinking you are going to live on planet that has the remotest resemblance to the one you have lived in all your life. THAT is WISHFUL THINKING! The LEAST of your problems is going to be worrying about the "zombie" humans getting your stuff.


NOTE: I pose these issues for your discussion. I will not argue the merits of them beyond this comment. If you disagree with anything I said, then you are entitled to be as wrong as you like.  ;D  :D
