Scientist makes horror prediction that the world will 'collapse in just 25 years (www.express.co.uk)

A scientist has made the shocking claim that there's a 49% chance the world will end in just 25 years. Jared Diamond, American scientist and historian, predicted civilisation could collapse by 2050. He told Intelligencer: "I would estimate the chances are about 49% that the world as we know it will collapse by about 2050."

Diamond explained that fisheries and farms across the globe are being "managed unsustainably", causing resources to be depleted at an alarming rate. He added: "At the rate we’re going now, resources that are essential for complex societies are being managed unsustainably. Fisheries around the world, most fisheries are being managed unsustainably, and they’re getting depleted.

"Farms around the world, most farms are being managed unsustainably. Soil, topsoil around the world. Fresh water around the world is being managed unsustainably."

The Pulitzer Prize winning author warned that we must come up with more sustainable practices by 2050, "or it'll be too late".

This is something historians struggle with, because "Collapse" has happened before, the most famous of which might be the Bronze Age Collapse, or the fall of the western Roman Empire in 473. Needless to say, those didn't result in human extinction, or even the extinction of human habitation in those locations (so Greece was inhabited before the Bronze age collapse, but that predates Classical Greece, which we think of as it's golden age, and one for humanity).

Specifically, it was (natural) climate change or political turmoil (those usually go hand in hand) making long established trade routes and subsistence patterns untenable, and with it, destroying the power of the people who controlled that trade. There was a reduction in trade, as the elites had the money to import, and the disposition to distinguish themselves from the lower classes. There was certainly some population reduction, because food was not moving as much, and populations were reduced to what the locality could support. I want to note that at this point, we see migrations (although we do see violence). I want to thank Patrick Wyman's podcast for teaching me this answer.

So I think, in this case, I think its likely we see this. The current power structure will probably not survive, although pockets of it may hold on in places, and maybe even survive into the next iteration (so think about the Catholic Church, an ancient roman institution survives to this day). Instead, I expect to see local polities spring up, holding on to or rejecting various aspects of the old world. A process of balkanization implies the rest of the world looks on in horror, but I expect to see some process of it happening everywhere. Immediately, these fragments will resemble the world we recognize, but in the centuries that follow, the world will become unrecognizable to us.

I think its also important to note that like, the destruction of the social order, which would suck for a lot of reasons (like the development of technology like vaccines), doesn't necessarily mean a "dark age." Some knowledge was lost (like Roman concrete in the fall of Rome) but I dont think the fall of the modern world precludes the loss of electricity, or motor vehicles, or even something like the telephone.

Thanks for the answer but I'm still not really certain what it would mean to me. I mean if these fascists went away, it might be worth it. Just depends on who rises to take their place.

You just asked what does collapse means, and I knew the answer. I certainly don't know what it would mean for you.

Well the purpose for asking what a world collapse looks like was to determine what life for a typical person would be and I consider myself to be a typical person (in the US). I kind of view it like the beginning of the movie Interstellar.

In that movie people still had houses but there were items that were in short supply. People had chronic illnesses and there wasn't much that could be done, so they would die prematurely. Crops were failing and it looked like the end of all, or virtually all, life was approaching. I wonder if that's what it looks like.

A lot of the answers were on a macro scale not a sort of day to day life scale. That's what I meant about what it would mean to me.
