On this topic, I can never end recommending Adam Curtis's series "All Watched Over by Machines of Loving Grace", and on this topic of "bounce back" the second episode in that series.
The concept of "natural equilibrium" is a 1950s cybernetic machine fantasy projected onto the natural world rather than an accurate reflection of ecological reality. We can model the world in the language of system theory, but the models we make there might not have much to say about the real world. We can claim that from system theory it follows that there must be an equilibrium (as somewhat of an expert, I can say that even that is not true) and that if we disrupt the system, things will eventually go back to that equilibrium. And if we don't see it, we just needed to wait longer.
The whole stack of logic is not really build on any proper reasoning. The parallel with economics based on the "homo economicus" is striking, also there you reason from an ideal model and try to make inductive statements about the real world, which in many places directly conflict with observation. The "eco-system" and "natural equilibrium" stem from this approach of applying system theory to ecology, and are ideas which are now _very_ ingrained in western thinking, but which are obviously off.
A bit of caution with this line of thinking, because I was blindsided by it after more than decade of hand waving away "academics"
When you have the mind of "the models are wrong", you tend to be brought there by select counter examples, and in that space you only feed on counter examples. "The experts are wrong (and you can be right in 15 minutes if you consume this media!)" is abundant.
The actual reality is "the models work great until they don't". Not "the models don't work."
Ironically, the experts, the ones building the "wrong" models, tend to be the ones most aware of this.

This varies substantially by field, or by subfield. There is a vast decades-long intellectual wasteland of bad economics predicated on bad models that are only appealing on normative grounds. The entire field of behavioral psychology might be a scam. Etc etc. Science advances one funeral at a time hard part because people are unwilling to let go of their models, even when they have outlived their usefulness or have been simply proven too wrong to be useful even in their original purpose.

I studied cognition and came to the very same, sad conclusion.
There’s a reason there was a reproduction crisis and it’s far from over. I remember vividly how one of my professors, during a paper debate, would end criticism with: “but it’s been published” as if that handwavy gesture could explain away serious research gaps that even graduate students saw through right away.
Shoddy statistics in a system that rewards quantity can do a lot of damage.

without getting too deep into "field purity" [0], it's certainly a field of study insofar as game theory, psychology, anthropology, etc. are fields of study. It's possible to make certain models of behavior or outcome potentials, but running experiments is significantly more difficult than e.g. physics or biology.
So it's science inasmuch as anything with n=1 repeatability can be science
Weirdly, it's much easier to run empirical experiments in psychology (my field), but economics for whatever reason is MUCH more rigorous and empirical than psychology in my experience.
It may have to do with the overall complexity being easier to effectively model. Psychology has such big error terms that you either give up or get comfortable with a lot of hand-waving and dogma. A huge proportion of psychologists are just activists and have no real interest in being scientists (beyond the prestige).

Economics is a scientific field in the same sense that Astrology and Politics are. You formulate theories about what your customers want to hear. Then test those theories by telling your customers things, while observing both immediate reactions and how situations develop over time. That latter in conjunction with formulating updated theories about what your customers want... Endless loop.

It's because the models have different purposes in decision making, in ways which decision makers don't often appreciate.
Models are still great at helping us understand the world and are in many ways the best thing we have. The problem is that today we are overly relying on them to make real policy interventions on an ecology (e.g. what is a "healthy" amount of animals to cull or fish) based on an ecosystem, which is just a poor model.
If we could get rid of this idea of "stability" and "equilibrium" in economics and ecology, I would be a happy man.

Maybe the best way to illustrate our point is to use weather models, as it's pretty tangible for regular people.
Weather models are ridiculously advanced running on super computers crunching a massive global network of real time data. But they still aren't anywhere close to perfect.
That being said, just because it rains on your birthday when it was said to be sunny, doesn't mean you delete your weather app, call meteorology pseudoscience, and start a substack of "the forecast was wrong again" blog posts.
People intuitively grasp this foolishness because they constantly interact with weather models. But for things they have almost no contact with, it's easy to write it off on a single "bad forecast"
(I'll also admit the caveat that not every model is as good (or bad) as weather models, another dimension at play to throw a wrench in peoples gears)

I was always a fan of what a former senior colleague ingrained in me early in my career:
- a model is primarily judged by its predictive power
A model that has no predictive utility is a bad model, but every model hits its limits in terms of predictive power. Some models have a very steep cliff in accuracy at the "edges", and some gradually lose fidelity like an out-of-focus photograph.
Most anti-science criticism I see is completely ignorant of what it really means to model a system or phenomenon: the challenges, the limitations, the end goal, the criteria for success, etc. It's sort of a statistical / scientific ignorance that's deeply cross-discipline. To perform science in a lot of ways is to engage with what it means to build a model, and in some ways, interrogate the universe.
If you're both an idiot and overconfident, it's tempting to throw your hands up and not engage with something as complex as "modeling", and just decide almost out of whimsy what the universe should truly be. But at least some people who find modeling too intellectually taxing at least admit that there are things that they'll never understand.

Even if we do make that claim, from practice in systems theory we should know that some systems have multiple potential equilibrium. If a system is perturbed, it may come to rest at a different equilibrium that is much less desirable.
I've worked with mechanical and computer systems where the ordering and timing of applied loads makes a significant difference to observed behavior. Sometimes you have to stop and restart the whole system when it ends up at an undesired equilibrium.
In the natural environment, stopping and restarting in a controlled manner is not something entirely in our control.

I don't really know anyone serious who thinks that ecological systems have a single stable equilibrium state.
Indeed, even the trivial systems you learn about at school, like predator-prey relationships are dynamic equilibria rather than static ones. Experiments clearly demonstrate trophic cascades can shift ecological systems from one meta-stable state to another (e.g. remove crabs from a rockpool, and the herbivore population explodes until it runs out of seaweed, at which point it crashes).
Evolution is obviously a progression between many quasi-stable states.
I think a stronger claim is that _economics_ doesn't recognise this; local incentives and the price feedback structure aren't enough to avoid pushing natural systems out of their current quasi-equilibria state into degraded states that are long-term also poorer for humans (e.g. collapsing fish populations). This is also pretty broadly understood, and why market interventions like fishing quotas exist. But in the conflict between "extract more more now" and "long term health of the ecosystem", "extract more now" is the economic default and "long term health" requires special pleading, so unsurprisingly the former tends to win.

This isn't me being pedantic, actual question:
Are we talking about whether nature is ever at equilibrium, or about how stable that equilibrium is?
A ball on the crest of a saddle is at equilibrium, but it isn't a very stable equilibrium.
Basically, are you saying the reality is that nature is always in flux, or that it doesn't take much to knock it toward a different stable state.

Curtis's stuff is all good fun but I'm skeptical that:
>The concept of "natural equilibrium" is a 1950s cybernetic machine fantasy
>The concept that nature maintains its condition is of ancient provenance. Herodotus asserted that predators never excessively consume prey populations and described this balance as "wonderful". Two of Plato's dialogues, the Timaeus and Protagoras myths, support the balance of nature concept...
This is the story of how one user spent too much time writing why he became disenchanted with Adam Curtis, how he had been a longtime fan. But eventually he saw through the same smoke and mirrors. He learned to see it all as uncharitable nonsense to convince others that technocracy is unassailable. He thought the parody was funny.
I like the Curtis stuff because it hits like old internet-core. It is entertainment that makes you think, but entertainment. Otherwise it would have been written work. But damn the guy can weave a story with some old videos and a soundtrack. As a genre, it's extremely approachable to make your own.

I have seen these parodies before, and while they are accurate in style, they seem to misunderstand or misrepresent Curtis' message. A message which is not that hard to understand, except that it falls comfortably outside of the Overton window:
"Driven by the seductive post-war fantasy that human beings and nature are self-regulating machines -- a cybernetic delusion shared equally by California tech-utopians, holistic ecologists, and free-market economists -- we willingly surrendered political power and moral responsibility to automated, network-driven systems, only to find ourselves trapped in a static, dehumanizing loop that cannot envision an alternative future and leaves the existing, unaccountable hierarchies of power completely intact."

No, I understand his message.
And again, this is exactly what I meant by "uncharitable nonsense to convince others that technocracy is unassailable." He regularly claims his job isn't to provide solutions or that solutions are increasingly unimaginable, yet that's the only thing that does matter.
If knowing more about how civilization got to this point suggests nothing to Curtis about how to escape from it and hasn't for three decades, despite his supposedly privileged epistemic position, why listen to him in the first place? The man obviously isn't interested in proposing or "raising awareness" of solutions, only problems.

antonvs 5 hours ago [-]
> Doesn't the premise of bouncing back imply an ideal state to bounce back to?
No, it's an "equilibrium" state, i.e. "a state of balance where opposing forces ... are equal" (from the MW definition.)
The general concept is that a stable system has at least one equilibrium state, in which no processes go out of control and potentially destroy the system.
A simple(?) example would be global warming - if the atmosphere keeps accumulating carbon, temperatures keep going up, the planet becomes uninhabitable, everything dies. Of course, that's subjectively an undesirable outcome for us - not an "ideal state", as you say - but the point is that any state in which no equilibrium can be reached (or at least approximated) exists is subject to such risks.
You could say that equilibrium is a necessary condition for an ideal state, but it's not sufficient. There can also be equilibrium states that are decidedly non-ideal, like the "everything dies" one I mentioned.
tkdb 3 hours ago [-]
I agree, and I've answered the same question before much as you have. I don't disagree with the value of equilibrium.
Our bodies are in a sort of equilibrium when healthy, and cancer is an example of emergence of destabilizing phenomena in the system.
Consider the Carboniferous–Permian oxygen maximum; it probably took tens of millions of years for oxygen levels to reach troublesome concentrations for plants, then tens of millions of years to return to "equilibrium."
Our current atmospheric concerns have been produced much faster, right? And I think we hope to improve the situation somewhat faster than ten million years.
My main point is that equilibrium is inherently subjective, bringing along time scales and traits that the observer cares about.
I supposed you could develop a "equilibrium for the most species at once" approach...

Even if that's true, quite a bit rides on how long "longer" is. If "longer" is a million years, that's not exactly good news.

But if you apply the logic that led to the conclusion of "natural equilibrium", truth of the matter is that we wouldn't be able to say if the waiting will be over before or after the heat death of the universe.
Even the "million years" is an overoptimistic view, and probably reflects the idea that the ecosystem was in some kind of messianic state of equilibrium before man arrived, which happened roughly in the last million years. But even that is broadly a fiction. Ecology is not a system, and it is not stable even without human intervention.

Yeah, it's a bit absurd on its face to speak of equilibrium in the context of evolution, which is basically a litany of innovations and equilibrium breaks.

I think what happened to the cod fishery off North America is really interesting. They overfished the cod then decided to regulate the fishery to let the population come back.

lithocarpus 6 hours ago [-]
There are often other factors too, than just the direct fishing, that keep a population low.
In the west of North America, like most places, almost all of the old growth forest was logged.
Some places where the soil and subsoil was particularly vulnerable to erosion and landsliding or just didn't have a lot of water capacity in the first place like on dry mountains, after these trees were removed and most of the soil washed away from rain, the forest simply has not come back a hundred years later. There are little trees gradaually getting started, and lots of mostly bare soil or rock still where erosion from rain is able to outpace the vegetation growth. It will likely take many thousand years for trees to get to the size they were before, and to build up the capacity for holding water like it had been.
In more abundant forests, trees regrow faster. But even there, a hundred years later, the total biomass per acre is often 10% of what it was as old growth forest, and the capacity for holding water on the land similarly much reduced. The old growth forests were the result of nature doing its thing often with help from humans for thousands of years and continually becoming richer. Eventually a major disturbance sets it back, but this might only happen ever 5 or 10 thousand years. This time humans did it.

The trees had much more utility to humans as fuel than it did as a forest at that moment, and unless you think biomass is an intrinsic good regardless of whether it helps humans, i dont see anything wrong with what happened.

Old growth forest continually grows becoming richer and richer, until one of those major setbacks which often are many thousand years in between.
Old growth forest creates more wood per year per acre than second or third growth after the old growth is cut. It also produces more food for humans and habitat for wildlife. It literally stabilizes the weather and pumps moisture inland by storing water and then releasing it. It holds water in the ground so that streams don't go dry and can support fish. It is much more resilient to wildfire.
In the redwood forest for example, 95% of it was clear cut, for a short term benefit. 90% of this wood that had been accumulated by the forest over thousands of years has now burned or rotted away within 100 years, and is gone.
What we're doing now is rapidly consuming everything, and these resources are steadily declining, and will run out and the human population will crash.
But yes, I do think more abundance and diversity of life is an intrinsic good, both for its own sake and for the long term thriving of humans on earth. Like any population of animals, if we consume everything that we live on and undermine the capacity of earth to support us, we will collapse.
That said humans can figure out how to help ecosystems recover and be more abundant. So it's not all over. But clearing the old growth forest is one of the worst things we do - up there with reckless mining that contaminates water.

I sort of agree, but there is a balance. Destroying a small portion of old growth to develop humans? Great!
Destroying millions of acres of old growth for cattle farming, which is essentially a luxury for human food, meh.. maybe we’re better off growing cattle in other places that are more suited to it, and eating less beef so that nature in those forests can continue nourishing those parts of the earth.
Some uses of the earth are good for both humans and their environment, and some are good for humans in the short term but at the cost of long-term sustainability.
And if we do things that aren’t sustainable then we use up valuable resources, when doing things in a more balanced way could support and benefit humans indefinitely.

From an ecological standpoint how is logging different than a naturally occurring forest fire? Or perhaps the forest fires never get strong enough to burn the old growth trees since they would happen more frequently via lightning strikes or natives clearing the brush/hunting?
Faelon 3 hours ago [-]
Forest fires don't replace America's forests with ecologically dead pasture, for one. Forest fires don't usually strip out the roots preventing the erosion, and they naturally lead to succession from plants which opportunize these events. There are even entire bird species which are dependent on these reliable forest fires like Kirtland's Warbler. The real issue is the scale. 99% of America's old growth forest was logged, and much of it was replaced with farm and pasture. We could more effectively encourage mass rewilding if we had collective action to rewild pasture and replace the lost nutrition with plant foods, which require a dramatically smaller land and water footprint.
lithocarpus 2 hours ago [-]
Exactly, forest fires usually don't kill most of the trees in an old growth forest. The trees are much bigger, hold a lot more water, and have much thicker fire-resistant bark. This is why you usually see charred parts on the bottom of living old growth trees - they survived fire.
Because the old growth was logged, the fires we have now are often able to kill 100% of the trees in an area because the trees are all small and young and vulnerable. And this is self perpetuating, because after such a fire the soil often erodes, and sun hits the ground directly keeping it dry - it takes a really long time to recover from in some places.
Each cycle of logging removes even more soil and makes the landscape drier, and resets the timer on how long it will be before the forest is able to survive a wildfire. It's a short term thing.
I'm not saying no one should ever cut a tree or use wood - and it can be done in better and worse ways, it's really complex. But in general, the repeated clearcutting of the pacific northwest is steadily degrading that landscape the same way repeated intensive till farming of the prairies is degrading that landscape - it's a relatively short term thing with diminishing returns.

if we're doing analogies to other complex systems, forests which have been patched and patched by different maintainers over the year are likely to have a lot of built up cruft, overlapping APIs, bloat, and of course a rewrite results in cleaned up code.

I feel like we should do our best to not destroy the environment, for altruistic reasons but also for the very selfish reason that I have children and relatives with children so I want to leave them with a place they can live in and enjoy not a mess they have to deal with.
I think we have made great strides at saving some near extinct species, the kakapo for example, but we can do better.
Reading the title, I was ready to come in with arguments about the Cambrian explosion and different timescales, the article it's self however is not really talking about things along those lines, it is talking about the short(or very short) term where we assume that once species will easily take up a niche that was occupied by another if one goes extinct. Which I believe is looking at things on the wrong timescale, even if we assume punctuated equilibrium rather than gradual evolution.

Nature itself ain't in no long term stasis, its just us humans projecting our wishful thinking on our environment. Planet is warming since last ice age (ie all glaciers in the Alps are provably receding since 1850 when measurements started, and ie vineyard region where I live was provably under huge glacier some 25k years ago).
Often cited mosquito eradication (at least those transmitting malaria, dengue, yellow fever, zika and so on) would change few things even though most folks would not even notice... and I couldn't welcome it more intensively. These academic discussions in the west would quickly die off when people around you start dying frequently from these (especially small children, but also grandparents or just weaker / more unlucky folks).
Massive droughts this summer still continuing here where I live wreaked way more havoc not only in insect world than any such engineering would do, yet I see no violent mass protests all around the world about banning cars, huge transport ships or commercial & private jet flying for example, or some other big pollutants. Literal frog in boiling water situation.

Agreed, we(collectively) do seem to assume and teach that the environment is/was in homeostasis before modern man when that is very much not the case.
However we do have measurable effects on the environment i.e. acid rain on the east coast due to the iron and steel foundries. We eliminated/reduced that heavily by implementing controls, same with the hole in the ozone.
I don't think that the path forward for repairing(if assuming all manmade)/changing what is going on is banning things as that is difficult to implement on the world wide scale that it would need to happen.
Case in point, China is one of the largest GHG emitters in terms of number but when it is brought up, the argument is they are smaller per capita and most of the emissions are due to them selling to the west anyway. If we said "Ok, let's stop manufacturing there", now you have the free trade people upset. Also the people who believe that you need trade in order to prevent war. Also everyone really likes cheap stuff, the man on the street may not care about who their senator is but they really like it when they can get very big TV for cheap. So it's politically untenable.
I think that we could do some Geo-engineering to reverse/fix the situation; carbon sequestration in the ocean, greening the Sahara. But then you have people worried about the second order effect, it costs money and who will pay and you may be doing it on someone else's land...Europe doing a big push to green the Sahara would be bad optics because of colonialism.
I think we will take action but unfortunately it will have to be after things get a lot worse because that is really the only way to get people aligned.

Shouldn't they simultaneously study the costs of biodiversity? For example, our species left highly biodiverse jungles for less diverse plains, and our bodies are designed to follow and prey on large herbivores that don't do jungle. Less biodiversity creates niches for new diversity. It isn't possible to understand the benefits without the costs.

It could be argued that some serious science starts with "just looking at correlations", guided by intangible drives like imagination and moral intuition.

Agreed. There are just too many unknowns. Certainly about how life started here(if indeed it did start here). But even more so about what's out there. There's so much we don't know even about the planets and moons in our own solar system, let alone other star systems. It's only recently we've become able to detect exoplanets in significant quantities at all, and we've still only scratched the surface really. And what we know about those planets is very limited. For most of them we don't know much except their distance to the star and estimated size. For a handful we have some information about their atmospheres, usually only enough to narrow it down to a couple of equally plausible models. It's hard for me to imagine us being able to conclusively detect life on an exoplanet. I think the best we'll be able to do in the next several decades is say we're pretty sure a planet's atmosphere contains chemical compounds for which there's no known abiotic origin. But there will be so much uncertainty there in terms of possible unknown abiotic origins that it would never feel conclusive.

The system may return, but less diversity means less resiliency. The 'return' isn't a return to baseline. That system return is an attempt to attain a state of function that is no longer available. That leaves this returned system in a constant state of stress. Stress on any system reduces function, increases failure rates, and extends repair times greatly. When a stressed system attempts to heal, many factors inhibit or outright prevent healing from occuring.
That's all observation, reasoning, and logic. Merely observing what occurs in a system that loses or gains is enough data to make fairly striking conclusions. The systems never return to baseline. Not once. Not ever. We've never observed a return to baseline after a species is destroyed, nor if an invasive species enters the system.
Once balance is lost, it cannot be attained again. Will not be. Has not been. Observed data is clear about this pattern. There is no equilibrium. There is a system that is functioning and then there is a system that no longer functions. There are no return to function systems in nature. Humans have not observed a mechanism that would bring that about, nor observed the occurrence of such.
One failure leads to another, and to another. Cascading. That's what we observe over generations of data collection.

The concept of "natural equilibrium" is a 1950s cybernetic machine fantasy projected onto the natural world rather than an accurate reflection of ecological reality. We can model the world in the language of system theory, but the models we make there might not have much to say about the real world. We can claim that from system theory it follows that there must be an equilibrium (as somewhat of an expert, I can say that even that is not true) and that if we disrupt the system, things will eventually go back to that equilibrium. And if we don't see it, we just needed to wait longer.
The whole stack of logic is not really build on any proper reasoning. The parallel with economics based on the "homo economicus" is striking, also there you reason from an ideal model and try to make inductive statements about the real world, which in many places directly conflict with observation. The "eco-system" and "natural equilibrium" stem from this approach of applying system theory to ecology, and are ideas which are now _very_ ingrained in western thinking, but which are obviously off.
Here is the start of that second episode: https://www.youtube.com/watch?v=FgoereMDUJ0
When you have the mind of "the models are wrong", you tend to be brought there by select counter examples, and in that space you only feed on counter examples. "The experts are wrong (and you can be right in 15 minutes if you consume this media!)" is abundant.
The actual reality is "the models work great until they don't". Not "the models don't work."
Ironically, the experts, the ones building the "wrong" models, tend to be the ones most aware of this.
This varies substantially by field, or by subfield. There is a vast decades-long intellectual wasteland of bad economics predicated on bad models that are only appealing on normative grounds. The entire field of behavioral psychology might be a scam. Etc etc. Science advances one funeral at a time hard part because people are unwilling to let go of their models, even when they have outlived their usefulness or have been simply proven too wrong to be useful even in their original purpose.
I studied cognition and came to the very same, sad conclusion. There’s a reason there was a reproduction crisis and it’s far from over. I remember vividly how one of my professors, during a paper debate, would end criticism with: “but it’s been published” as if that handwavy gesture could explain away serious research gaps that even graduate students saw through right away. Shoddy statistics in a system that rewards quantity can do a lot of damage.
So it's science inasmuch as anything with n=1 repeatability can be science
[0]: https://xkcd.com/435/
It may have to do with the overall complexity being easier to effectively model. Psychology has such big error terms that you either give up or get comfortable with a lot of hand-waving and dogma. A huge proportion of psychologists are just activists and have no real interest in being scientists (beyond the prestige).
Do they believe it's a science? Assume that Upton Sinclair's famous quote applies.
Models are still great at helping us understand the world and are in many ways the best thing we have. The problem is that today we are overly relying on them to make real policy interventions on an ecology (e.g. what is a "healthy" amount of animals to cull or fish) based on an ecosystem, which is just a poor model.
If we could get rid of this idea of "stability" and "equilibrium" in economics and ecology, I would be a happy man.
> Ironically, the experts, the ones building the "wrong" models, tend to be the ones most aware of this
Exactly why I'm here :-)
Weather models are ridiculously advanced running on super computers crunching a massive global network of real time data. But they still aren't anywhere close to perfect.
That being said, just because it rains on your birthday when it was said to be sunny, doesn't mean you delete your weather app, call meteorology pseudoscience, and start a substack of "the forecast was wrong again" blog posts.
People intuitively grasp this foolishness because they constantly interact with weather models. But for things they have almost no contact with, it's easy to write it off on a single "bad forecast"
(I'll also admit the caveat that not every model is as good (or bad) as weather models, another dimension at play to throw a wrench in peoples gears)
Of course, they never convinced ME! Silly, wannabe flat earthers.
Most anti-science criticism I see is completely ignorant of what it really means to model a system or phenomenon: the challenges, the limitations, the end goal, the criteria for success, etc. It's sort of a statistical / scientific ignorance that's deeply cross-discipline. To perform science in a lot of ways is to engage with what it means to build a model, and in some ways, interrogate the universe.
If you're both an idiot and overconfident, it's tempting to throw your hands up and not engage with something as complex as "modeling", and just decide almost out of whimsy what the universe should truly be. But at least some people who find modeling too intellectually taxing at least admit that there are things that they'll never understand.
Even if we do make that claim, from practice in systems theory we should know that some systems have multiple potential equilibrium. If a system is perturbed, it may come to rest at a different equilibrium that is much less desirable.
I've worked with mechanical and computer systems where the ordering and timing of applied loads makes a significant difference to observed behavior. Sometimes you have to stop and restart the whole system when it ends up at an undesired equilibrium.
In the natural environment, stopping and restarting in a controlled manner is not something entirely in our control.
That's exactly how we got humans rather than the objectively better rulers of the planet, the dinosaurs.
In fact, such a distinction might characterize the difference between pessimism and optimism.
Indeed, even the trivial systems you learn about at school, like predator-prey relationships are dynamic equilibria rather than static ones. Experiments clearly demonstrate trophic cascades can shift ecological systems from one meta-stable state to another (e.g. remove crabs from a rockpool, and the herbivore population explodes until it runs out of seaweed, at which point it crashes).
Evolution is obviously a progression between many quasi-stable states.
I think a stronger claim is that _economics_ doesn't recognise this; local incentives and the price feedback structure aren't enough to avoid pushing natural systems out of their current quasi-equilibria state into degraded states that are long-term also poorer for humans (e.g. collapsing fish populations). This is also pretty broadly understood, and why market interventions like fishing quotas exist. But in the conflict between "extract more more now" and "long term health of the ecosystem", "extract more now" is the economic default and "long term health" requires special pleading, so unsurprisingly the former tends to win.
Are we talking about whether nature is ever at equilibrium, or about how stable that equilibrium is?
A ball on the crest of a saddle is at equilibrium, but it isn't a very stable equilibrium.
Basically, are you saying the reality is that nature is always in flux, or that it doesn't take much to knock it toward a different stable state.
>The concept of "natural equilibrium" is a 1950s cybernetic machine fantasy
Looking at https://en.wikipedia.org/wiki/Balance_of_nature :
>The concept that nature maintains its condition is of ancient provenance. Herodotus asserted that predators never excessively consume prey populations and described this balance as "wonderful". Two of Plato's dialogues, the Timaeus and Protagoras myths, support the balance of nature concept...
But this was a fantasy.
(Curtis's entire ouevre can be summarized in 18 seconds: https://www.youtube.com/watch?v=3YSwCJIpSXQ )
I like the Curtis stuff because it hits like old internet-core. It is entertainment that makes you think, but entertainment. Otherwise it would have been written work. But damn the guy can weave a story with some old videos and a soundtrack. As a genre, it's extremely approachable to make your own.
Sometimes it seems like shorts and tiktoks are like a bad Adam Curtis film. 30s highlights stitched together with no relation, garing transitions, ads.
Maybe I can put together a greasemonkey script to make YT shorts Adam Curtis themed. Maybe I won't feel as guilty, maybe it will all make sense.
"Driven by the seductive post-war fantasy that human beings and nature are self-regulating machines -- a cybernetic delusion shared equally by California tech-utopians, holistic ecologists, and free-market economists -- we willingly surrendered political power and moral responsibility to automated, network-driven systems, only to find ourselves trapped in a static, dehumanizing loop that cannot envision an alternative future and leaves the existing, unaccountable hierarchies of power completely intact."
And again, this is exactly what I meant by "uncharitable nonsense to convince others that technocracy is unassailable." He regularly claims his job isn't to provide solutions or that solutions are increasingly unimaginable, yet that's the only thing that does matter.
If knowing more about how civilization got to this point suggests nothing to Curtis about how to escape from it and hasn't for three decades, despite his supposedly privileged epistemic position, why listen to him in the first place? The man obviously isn't interested in proposing or "raising awareness" of solutions, only problems.
I don't need another six hours explaining why I'm right to be dissatisfied. I already am. Tell me what you've learned that might make me less powerless, not more.
And there we have it: ideal state for one species? the most possible species? longevity for individuals or the species?
The myth of some "natural" (the word literally means without human influence) state that is desired/better is somewhat ironic, right?
Any ideal state brings with it subjective criteria.
No, it's an "equilibrium" state, i.e. "a state of balance where opposing forces ... are equal" (from the MW definition.)
The general concept is that a stable system has at least one equilibrium state, in which no processes go out of control and potentially destroy the system.
A simple(?) example would be global warming - if the atmosphere keeps accumulating carbon, temperatures keep going up, the planet becomes uninhabitable, everything dies. Of course, that's subjectively an undesirable outcome for us - not an "ideal state", as you say - but the point is that any state in which no equilibrium can be reached (or at least approximated) exists is subject to such risks.
You could say that equilibrium is a necessary condition for an ideal state, but it's not sufficient. There can also be equilibrium states that are decidedly non-ideal, like the "everything dies" one I mentioned.
Our bodies are in a sort of equilibrium when healthy, and cancer is an example of emergence of destabilizing phenomena in the system.
Consider the Carboniferous–Permian oxygen maximum; it probably took tens of millions of years for oxygen levels to reach troublesome concentrations for plants, then tens of millions of years to return to "equilibrium."
Our current atmospheric concerns have been produced much faster, right? And I think we hope to improve the situation somewhat faster than ten million years.
My main point is that equilibrium is inherently subjective, bringing along time scales and traits that the observer cares about.
I supposed you could develop a "equilibrium for the most species at once" approach...
Even if that's true, quite a bit rides on how long "longer" is. If "longer" is a million years, that's not exactly good news.
Even the "million years" is an overoptimistic view, and probably reflects the idea that the ecosystem was in some kind of messianic state of equilibrium before man arrived, which happened roughly in the last million years. But even that is broadly a fiction. Ecology is not a system, and it is not stable even without human intervention.
umm, that is not what the word equilibrium means. Obviously no system is stable to every and all disruption.
In the west of North America, like most places, almost all of the old growth forest was logged.
Some places where the soil and subsoil was particularly vulnerable to erosion and landsliding or just didn't have a lot of water capacity in the first place like on dry mountains, after these trees were removed and most of the soil washed away from rain, the forest simply has not come back a hundred years later. There are little trees gradaually getting started, and lots of mostly bare soil or rock still where erosion from rain is able to outpace the vegetation growth. It will likely take many thousand years for trees to get to the size they were before, and to build up the capacity for holding water like it had been.
In more abundant forests, trees regrow faster. But even there, a hundred years later, the total biomass per acre is often 10% of what it was as old growth forest, and the capacity for holding water on the land similarly much reduced. The old growth forests were the result of nature doing its thing often with help from humans for thousands of years and continually becoming richer. Eventually a major disturbance sets it back, but this might only happen ever 5 or 10 thousand years. This time humans did it.
Even if the Earth has emotions, who are we to assume it would prefer to be covered in throbbing life rather than to have a surface that was burnt to a cinder? Maybe we itch. What we're doing when we talk about a long-term forest recovery is projecting our fantasies about how we would feel if we were the Earth. If we destroy it for ourselves, we've simply destroyed it. We were the ones who assigned value to it.
This is us burning our own house down. The ground that the house is on does not care that we are obviously suicidal.
Is the point that people moving into the American west should have froze to death rather than chop down trees for fire and shelter? The trees had much more utility to humans as fuel than it did as a forest at that moment, and unless you think biomass is an intrinsic good regardless of whether it helps humans, i dont see anything wrong with what happened.
Old growth forest creates more wood per year per acre than second or third growth after the old growth is cut. It also produces more food for humans and habitat for wildlife. It literally stabilizes the weather and pumps moisture inland by storing water and then releasing it. It holds water in the ground so that streams don't go dry and can support fish. It is much more resilient to wildfire.
In the redwood forest for example, 95% of it was clear cut, for a short term benefit. 90% of this wood that had been accumulated by the forest over thousands of years has now burned or rotted away within 100 years, and is gone.
What we're doing now is rapidly consuming everything, and these resources are steadily declining, and will run out and the human population will crash.
But yes, I do think more abundance and diversity of life is an intrinsic good, both for its own sake and for the long term thriving of humans on earth. Like any population of animals, if we consume everything that we live on and undermine the capacity of earth to support us, we will collapse.
That said humans can figure out how to help ecosystems recover and be more abundant. So it's not all over. But clearing the old growth forest is one of the worst things we do - up there with reckless mining that contaminates water.
We tolerate extracting resources from the biosphere because it supports a higher human population. Barring actions that will lead to extinction events, I think we should continue to extract resources from the planet that support human flourishing.
Destroying millions of acres of old growth for cattle farming, which is essentially a luxury for human food, meh.. maybe we’re better off growing cattle in other places that are more suited to it, and eating less beef so that nature in those forests can continue nourishing those parts of the earth.
Some uses of the earth are good for both humans and their environment, and some are good for humans in the short term but at the cost of long-term sustainability.
And if we do things that aren’t sustainable then we use up valuable resources, when doing things in a more balanced way could support and benefit humans indefinitely.
Move on...
Instead, we're depleting resources faster and faster primarily because the people directing most of the world's economic resources want to accumulate even more money even faster. They just don't give a damn about what comes after.
Because the old growth was logged, the fires we have now are often able to kill 100% of the trees in an area because the trees are all small and young and vulnerable. And this is self perpetuating, because after such a fire the soil often erodes, and sun hits the ground directly keeping it dry - it takes a really long time to recover from in some places.
Each cycle of logging removes even more soil and makes the landscape drier, and resets the timer on how long it will be before the forest is able to survive a wildfire. It's a short term thing.
I'm not saying no one should ever cut a tree or use wood - and it can be done in better and worse ways, it's really complex. But in general, the repeated clearcutting of the pacific northwest is steadily degrading that landscape the same way repeated intensive till farming of the prairies is degrading that landscape - it's a relatively short term thing with diminishing returns.
All that said I still think we should just extinct disease carrying mosquitoes.
The article is more focused on oceanic and coastal diversity but I agree about the mosquitoes.
The modern version of Carthage should be destroyed.

It's an invasive pathogen to a mosquito population, but it benefits humans.

The Sahara is teeming with life compared to Mars, but we also know it once hosted significantly more life before it was a desert. That old system collapsed.

Humorous, but not inaccurate about what climate change means to primates. =3
Down the line there is a state nature will be in. More/less plants and animals. Who knows. It might not be a pleasant state for people.
The concern seems to be that it will change faster than we can change. What happens if the climate of an agricultural area changes in a lifetime? or a generation? or a decade?
Nature is in a state at every point of time. This not-especially-useful perspective means there’s nothing to bounce back from.
It reminds me of clever people tut-tutting when talking about an apocalypse. “Ah, but the planet will still be here!”
Prefacing this by saying that I am constantly saddened by the scale of human activities and impact. It hard to find places that are untouched by human. But I sometimes ask what conservationism is trying to conserve. The parts that we find pretty and meaningful. It's not saving the planet, it's saving the insta background. That last one felt really cynical to me.
Whether "nature recovers" is silly talk that makes you want to capitalize "nature" because you're anthropomorphizing so hard. The question is whether nature will recover for us, or on the other hand whether we will be able to adjust to the permanent changes we have imposed on nature.

I think we have made great strides at saving some near extinct species, the kakapo for example, but we can do better.
Reading the title, I was ready to come in with arguments about the Cambrian explosion and different timescales, the article it's self however is not really talking about things along those lines, it is talking about the short(or very short) term where we assume that once species will easily take up a niche that was occupied by another if one goes extinct. Which I believe is looking at things on the wrong timescale, even if we assume punctuated equilibrium rather than gradual evolution.
Often cited mosquito eradication (at least those transmitting malaria, dengue, yellow fever, zika and so on) would change few things even though most folks would not even notice... and I couldn't welcome it more intensively. These academic discussions in the west would quickly die off when people around you start dying frequently from these (especially small children, but also grandparents or just weaker / more unlucky folks).
Massive droughts this summer still continuing here where I live wreaked way more havoc not only in insect world than any such engineering would do, yet I see no violent mass protests all around the world about banning cars, huge transport ships or commercial & private jet flying for example, or some other big pollutants. Literal frog in boiling water situation.
However we do have measurable effects on the environment i.e. acid rain on the east coast due to the iron and steel foundries. We eliminated/reduced that heavily by implementing controls, same with the hole in the ozone.
I don't think that the path forward for repairing(if assuming all manmade)/changing what is going on is banning things as that is difficult to implement on the world wide scale that it would need to happen.
Case in point, China is one of the largest GHG emitters in terms of number but when it is brought up, the argument is they are smaller per capita and most of the emissions are due to them selling to the west anyway. If we said "Ok, let's stop manufacturing there", now you have the free trade people upset. Also the people who believe that you need trade in order to prevent war. Also everyone really likes cheap stuff, the man on the street may not care about who their senator is but they really like it when they can get very big TV for cheap. So it's politically untenable.
I think that we could do some Geo-engineering to reverse/fix the situation; carbon sequestration in the ocean, greening the Sahara. But then you have people worried about the second order effect, it costs money and who will pay and you may be doing it on someone else's land...Europe doing a big push to green the Sahara would be bad optics because of colonialism.
I think we will take action but unfortunately it will have to be after things get a lot worse because that is really the only way to get people aligned.
Shouldn't they simultaneously study the costs of biodiversity? For example, our species left highly biodiverse jungles for less diverse plains, and our bodies are designed to follow and prey on large herbivores that don't do jungle. Less biodiversity creates niches for new diversity. It isn't possible to understand the benefits without the costs.
Of course, for many reasons, we should try not to drive species to extinction. That's not really science; it's just basic moral intuition. People seem embarrassed to admit that their motivations are perfectly reasonable things like "I like living things and we shouldn't kill them off".
It could be argued that some serious science starts with "just looking at correlations", guided by intangible drives like imagination and moral intuition. I wouldn't dismiss it as "not really science", and may even lean toward saying that it's important for the scientific process, or even the development of mathematics, to listen to your moral intuition and follow your nose. It's often driven by asking questions and posing theories.
Sure, but it can't end with "just looking at correlations". The rigorous experimental follow through has to be there otherwise its just data analytics not science. Sure analyzing data is a key part of science but its not even close to all of it.
Just feels like makework. And even if the data show that, e.g., killing off all hummingbirds would improve pollination rates, no one would be like "yee-haw let's do it", right?
Fig. 2 [1] lists them. Fig. 3 I think indicates that 20 of them have positive effect size on biodiversity, which I think was the point. "Learning and inspiration" is an interesting category. Carbon sequestration ranks high, with Terrestrial (as opposed to the larger Oceanic) having quite a few studies behind it.

Push your leaders to stay the course
Uhh, yeah, I think that one was certainly known to be a non-starter when drafted in 2022. Most of the targets are vague and subject to interpretation. Some of them are loaded with overly effusive language. Not an agreement, it seems, that will garner much in the way of political support. It was clearly designed as idealism rather than policy.
Paraphrased: "Nature will be fine, it's humanity we should be worried about."
Bounce back can take millions of years.
In the end this is about protecting and preserving our own ecosystem without which we will perish.
Instead of trying to perform a balancing act with nature we should just continue to shape things into things that are more convenient to us. Like redirecting water into a desert.
Or take the Netherlands, that used to be a lot of water and now it is a lot of flat land.
The knock on effects of those changes to one of the most important and diverse ecosystems on the planet cannot possibly be completely predicted beforehand.
For all we know the universe could be teeming with life, in whatever shape or form. And since we see the first signs of life about 500 million years after the plant was formed, there's a good argument to be made that life doesn't need much more than a stable energy gradient and some basic building blocks to get started.
Nearby me is a cloud forest in central America. The last time we had a strong El Nino, substantial amounts of endemic amphibians that live up in those forests lost the mist-melt puddles they depended on. If the drought we're experiencing continues as long as expected from this cycle, we're going to lose a lot of beautiful frogs forever.
Can I do anything about this? Find my favorite frog community on my favorite mountain and regularly lug a backpack of water up there? Run up a sprinkler system? Will it make a difference?
I refuse to believe that humanity on a whole is that incapable. Or at least unwilling to try to do something different.
call me crazy but i think human behavior is in fact a subset of "life"
That's all observation, reasoning, and logic. Merely observing what occurs in a system that loses or gains is enough data to make fairly striking conclusions. The systems never return to baseline. Not once. Not ever. We've never observed a return to baseline after a species is destroyed, nor if an invasive species enters the system.
Once balance is lost, it cannot be attained again. Will not be. Has not been. Observed data is clear about this pattern. There is no equilibrium. There is a system that is functioning and then there is a system that no longer functions. There are no return to function systems in nature. Humans have not observed a mechanism that would bring that about, nor observed the occurrence of such.
One failure leads to another, and to another. Cascading. That's what we observe over generations of data collection.

The insects require a whole lot more things, so if we don't save the remnants, the home of all of our remnant biodiversity... what was it, the guy going on telling everybody 'if you plant nature in your yard, it'll come back'... it's assuming that the insects are just going to come there. It doesn't happen. You have to save the remnants... Our generation needs to deploy great armies to identifying and preserving what little remnants we have left. Otherwise, there'll be no germ material out of which to build a tomorrow. It'll all be gone.

Even letting aside any survival mechanism we have there are two rational posibilities:
1. We are alone in the universe => super huge loss of complexity and consciousness
2. We are not alone but at Universe scale intelligent life seems rather scarce => still huge loss in diversity
That's why it's important to find joy in the moment and ways to share that joy and happiness with those around you.
