    This is literally why we have apex predators such as wolves. They help clamp down on the old and the sick so that prions (mad cow disease) does not spread to other species or humans. It cannot infect wolves.

    When you kill off all the apex predators, like when Montana governor Greg Gianforte authorized the massacre of 100 wolves, you see explosions of extremely dangerous diseases and land degradation as deer damage tree roots, gardens, meadows, streams, and farms.

    Not only that, but killing members of wolf packs causes their families to fall apart and everyone to scatter. That means wolves alone. Which cannot hunt pack animals which require coordination. So then they go after the easiest meal: dumbass farm animals who have zero survival instincts and whose ranchers no longer employ people to look after the herds in great enough numbers like the olden days. The cycle then perpetuates, as mad-cow contaminated soils spread and spread…

            Could be! I’ve spent the last 3 or so years with little to do but think, read, argue and watch youtube. I tend to watch mostly educational content, ranging from the big ones (“nile red”, “veritasium”, nutshell I can’t spell, “world science festival”) to lesser known ones (“sci-show”, “fall of civilizations”, “economics explained”, “donna” and a bunch of others). Robert Sapolsky is amazing, btw, look him up if you don’t already know who he is. But anyway, most recently I learned about the last 5 mass extinctions in a video by “paleo analysis”

            Anyway…

            I think many people will die in the upcoming climate crisis (and are already dying) but I don’t think humanity itself will completely die out. I mean, we are not the pinnacle of evolution that some people would like to think, and we’re still changing and likely will continue to do so as our environment changes. But die out completely? Prrrrrobably not. As a species we’re highly adaptive (even though some idiots in power hold us back) and I think that at least enough of us will survive to continue the species.

            Maybe not, but I think we have a shot that’s no more unlikely than anything else that’s happened so far

              I think you’re right. Having assets spread across different investments protects one from going bankrupt. Having our species spread across the different climates means that we may still survive but probably not most of us.

        It’s in the OP article. They haven’t found any infections yet, and it doesn’t appear to affect them. Apex predators have, prior to human intervention, always hunted the old, the young, and the sick. Mother nature appears to have found a way around apex predators all dying from disease to balance the environment.

          Afaik it’s because they naturally die before the disease becomes crippling. Or it becomes crippling around or after the normal lifespan of the animal. It doesn’t mean they aren’t affected, it means it doesn’t affect them before they would normally die…

          Please don’t anthropomorphize “mother nature”. Mother nature doesn’t think, or make decisions, it is a natural progression of life and death… There is a process and a cycle to much of it, hand waving “mother nature finds a way” ignores and dismisses the reality of it, and excludes the science that helps us understand how our world actually works.

            I believe canines were found to be resistant to prion diseases, as they evolved to eat all manner of sick, dying and dead animals. Likely something to do with digestion, gut barrier or blood-brain barrier. Canines are pretty unique in their ability to eat almost anything that was once alive without getting sick.

            CWD is a very fast acting disease compared to most prison diseases, and should easily become visible during the lifespan of a dog or wolf.

      Can’t… Infect… Wolves?

      You do know that prions aren’t living things right? They don’t “infect”, they are a physical change to a compound (protein) that spreads to other similar compounds it touches. It’s not a virus, or a bacteria.

      Unless wolves lack the same proteins that deer also have? Usually this is a mammal thing, not a species thing.

    If a mad-cow-like disease jumped the barrier to humans and began spreading through Americans, the main problem in eradicating it would be that basically no one would be able to tell the difference from the average ‘Enthusiastic’ Republican Voter and someone whose brain is melting due to an actual pathogen.

        We’re actually not sure about that. Some prions do spread by eating the meat of infected animals, but I think we can be pretty sure that’s not what’s happening in a wild deer population. Prions can also be found in the environment, including deposited on grasses and plants, where that can last a very long time.

        We do not know if this disease is or will become communicable to predator animals or what the potential is for environmental spread to livestock. We do know a bit more about the BSE than some others, but there’s a bunch we know exist that we know little to nothing about, and it’s guaranteed there’s more out there that we haven’t encountered yet.

            Occasionally they do consume meat as far as I know (as several herbivores do), but if that were a serious candidate it would be among the principle lines of transmission being investigated.

            Zoonotic diseases are investigated by cross-disciplinary teams with experience ranging from public health and disease experts to wildlife biologists and ecologists. I did some work on a similar topic with the National Parks Service so I know a bit about how these are approached. I have no involvement with this and I’ve never worked on prion contagion models - like I said, we just don’t know. But I do have experience in the area.

            Prions have been found in soil, on grass and plants, and do not get quickly degraded by sun and rain. We do know that this disease is density dependent, so you’d need a model of deer going carnivore and cannibal in a density dependent natural model, which is not a phenomenon I’m familiar with.

            So what I’m saying is that we just don’t know what the deer-deer vector is or if a predation vector exists as a secondary transmission or if one will appear.

        Prion diseases can take decades to show symptoms, like with CJD, and are very hard to test for in humans.

        It might not be a question of whether it can jump species barriers, but when we will know it did, which is why the CDC can’t and won’t ring any alarm bells, just advise caution, until it’s either too late for individuals or a confirmed non-issue.

        There was a study that claimed it had jumped to chimps/monkeys in a testing environment but last I heard it was disputed, but that still leaves the average citizen with plenty of reason to not

        Checks notes

        Eat a diseased animal.

        Source your venison, it should be tested if it’s from an affected area but you never can trust suppliers for wild game.

        Consider just eating, you know, cow, or only venison from a trusted source.

        Preferably the person that shot and had it butchered.

          The issue is that deer dont eat each other often enough for that to be how they spread it among each other.

          So whatever vector is moving it around in them, which we dont actually know yet, is the more likely risk of an actual jump. Cant not take a risk if you cant tell if its risky.

          It’s actually worse than a virus.

          Once an environment is infected, the pathogen is extremely hard to eradicate. It can persist for years in dirt or on surfaces, and scientists report it is resistant to disinfectants, formaldehyde, radiation and incineration at 600C (1,100F).

          Biologist here. That’s not where I’d put the association. I’m going to simplify things a bit because this is going to be a long post, but hopefully this will help.

          I think you’re thinking about the effects of heat on proteins. We can destabilize macromolecules by heating them, sometimes causing permanent damage. That takes a lot of heat, though. The planet would be long dead before we had to worry about the environmental temperature denaturing proteins.

          Biologist related joke: How do you unscramble an egg?
          Feed it to a chicken.

          So, when the microscope was invented, people were startled to discover what were obviously living organisms in a drop of pond water. Discovery led to discovery, and we ended up learning about bacteria and the germ theory of disease. Some bacteria are really good (in that without them you would die), and some are really bad (like if you get infected you could die), but most are neutral. I do not believe there’s any direct connection between the global temperature and the rate of mutation in bacteria. That’s not to say there’s not a connection between climate change and disease rates. I’ll talk about that later.

          So later on we discovered viruses. Viruses are much smaller than bacteria. While a bacterium is a cell with a whole physiology going on, a virus consists of a bit of genetic material bound in an envelope of proteins. The envelope will gain access to a cell and inject its genetic material, which the cell’s normal processes will start to work on, producing more viruses. Many people don’t consider viruses “alive.” I do, because I’m approaching it from a different direction. Again, the rate of mutation there isn’t really directly affected by a rise in global temperature, but there is a disease rate relationship.

          We only discovered prions more recently. They’re even more simple than viruses. They’re really just a protein. We don’t understand them very well yet. The danger comes from the fact that prions can force other proteins to become copies of themselves. They can cause things like mad cow disease. They’re incredibly hardy and don’t mutate faster because of climate change. They’re very scary diseases with no known treatment and in some cases unknown transmission paths.

          This one is a prion.

          I think we can find correlations between disease in animals and climate change. Climate change forces animals into new environments where they can encounter diseases they’ve never faced before and to which they’re susceptible.

          Even more important is the common root cause of industrialization and human expansion and environmental destruction. Again, forcing more animals together magnifies the impact of communicable diseases, and things like the use of antibiotics to make factory farming as profitable as possible has the inevitable consequences of making diseases that are harder to treat.

              One of the problems is that we don’t know. It might be environmental contamination (eg deposits on grass or in soil). Ebola patient 0 was thought to be a toddler-aged child who ate a piece of fruit that had been contaminated by dung from an infected bat (Ebola, like many of our diseases, is zoonotic). It’s also thought to potentially come from preparing meat from an infected animal. If it’s in the environment, it may also come from some social behavior, like grooming or wound cleaning. Could it be transmitted by parasites that jump from host to host drinking blood? No idea. I’m just spitballing based on how some other diseases become density dependent.

              Prions are absolutely fascinating. I really hope they make a lot of progress.

          Not this pathogen. Prions are not living organisms, not even as much as viruses, and are extremely resistant to both heat and cold. It’s the same stuff that caused the mad cow disease in Britain.

    I believe it’s made the jump into a certain species of monkey in a lab environment last I knew, but the jump to humans hasn’t been seen and isn’t a given. This is a clickbait title. If you’re hunting game, make sure to get it tested with samples taken at a wildlife check station before consuming and you’re likely safe here.
