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".

What does collapse even mean? All humanity dies? Fifty percent of humanity dies? Many die and those that don't revert to Mad Max life styles?

The collapse of society "as we know it" where we as a species cannot survive by following the same.lifestyle we have depended on in the past.

Our company helps manage a significant percentage of a critical piece of nationwide infrastructure. With what I see everyday, my wife and I have decided to buy fertile land that can be farmed and has its own source of subterranean water so that we can grow enough food to survive (we already switched to plant based diets). We also are investing heavily so that our home can be "off-grid". Summer is covered, but we are still working on winter power generation.

We are not at "prepper" level, but if you're building a new home, why not try to build in some resiliency?

Funny I'm in the process of going solar and where I live, I'm not allowed to go off grid. How stupid is that?

[–] Nomecks@lemmy.ca 1 points 4 hours ago

You can still buy a battery bank and hybrid inverter that'll do solar -> battery -> grid. It's not full off grid, but you can almost completely eleminate grid usage.

[–] zod000@lemmy.dbzer0.com 1 points 23 hours ago (1 children)

I wasn't allowed to go off grid in my previous home where I had solar installed either. There was also a hard cap on the amount of solar I was allowed to install. Both of these rules were put in place due to lobbying from the largest power company in the region (Duke Energy in my case). It totally sucks,

[–] Professorozone@lemmy.world 1 points 22 hours ago (1 children)

Was it Florida because that's where I am and the rules are the same as what you've stated?

[–] Professorozone@lemmy.world 2 points 22 hours ago (1 children)

I'm on the East Coast. So I wonder what happens if you put enough solar on your house to go off grid and then just don't pay your power company? They put you in jail? LOL.

[–] zod000@lemmy.dbzer0.com 1 points 5 hours ago

Sorry, I don't recall the actual specifics now. I believe it was something like they made it a code violation to not have your home connected to the power grid and you just get fined and harassed until you "fix" it.

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.

[–] Brutticus@midwest.social 1 points 1 day ago (1 children)

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

[–] Professorozone@lemmy.world 1 points 1 day ago* (last edited 1 day ago)

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.

no more strawberry frosted doughnuts at Dunks.

The general breakdown of civilization,.nad mutiple points of fialuer that.can no longer be papered over.

and no one.comes bevase theres been too many disasters.

A bridge collaoaes and no one foxes it

But... I want them to fox the bridges :(

We're rather resilient, but it's gonna be dicey.

[–] ameancow@lemmy.world -1 points 2 days ago* (last edited 2 days ago) (1 children)

They've been making these kinds of predictions for a long time. This doesn't mean that there aren't very real existential threats to humanity around every corner, we may well experience a complete disaster, lord knows our logistics chain is delicate and largely ignored and props up everything we care about.

But what a lot of people miss in all of these predictions, is how adaptable and malleable human life is.

Will there be flooded cities and shanty-towns across coasts? Probably. Will there be gleaming cities of solar-powered utopia? Also probably. Will there be unrest, crime and war and famine? Absolutely. Will there be new comforts and escapes and new ways to stay safe and protected by your state in return for your attention, your money and your time? Also absolutely. Will it all be fragile? Yes, and it is now as well.

The future doesn't hold just one thing, it holds many things. The future has always been the same: more of everything and then some. Look at us now, people predicted by this time we would have flying cars and robots... which we do! In some places. But we also still have uncontacted amazonian tribes, so we have everything we had in the previous century plus more.

Utopia? Have you see Earth today?

[–] ameancow@lemmy.world 2 points 1 day ago

There will be no shortage of wealthy liches who want to create some kind of bubble-city where everything looks perfect. We already have it now, it will just become more stratified and more atomized.
