The main obstacle to achieving "sustainability" is population size.  All that needs to happen is for conditions to change enough so that the total population of Homo Saps and our domesticated animals and plants remains at or below .0001% of the total biomass on the planet and the species will be sustainable.  About 2 orders of magnitude, leaving around ~100M meat packages ambulatory at any given time.

A sufficient increase in the Death Rate of people past reproductive age to 99% coupled with a Fertility Rate <1 for females should drop the population down to a sustainable level in a few generations, then after that these two parameters can self adjust to maintain a steady population of homo saps between  0-60 years of age of around 100M sustainable meat packages.

Famine, Pestilence and War will probably accelerate the population reduction so that it achieves a sustainable figure more rapidly, perhaps as fast as within a single generation.  Such a rapid reduction is not ideal since it would be very socially disruptive, but once all the corpses were picked clean by scavengers life would settle down to the new normal.

Quality of life would improve dramatically with the disappearance of fast food, Netflix and Rap music.  The disappearance of smart phones would lead to the gradual rediscovery of sex by teenagers.  We will have only have two genders, people with assholes and people who are assholes.

Hanna says she is a data scientist.  Meaning she gave herself permission to cherry-pick a few graphs and ignore some others, because halfway through:

We need to move away from fossil fuels while feeding eight, nine, ten, billion people  at the same time.

Not possible.  Hanna has no graph to show how to do this.  Hanna Ritchie is a nice enough person.  As human intelligence goes Hanna seems to be on the high side of the curve.  Dummies don't give TED talks.  But Hanna smokes the hopium.

Hanna is a nebie to the world of doom.  Hanna does not understand how big eight, nine, ten, billion people is.  She is a data scientist really?  How does a data scientist not understand overshoot and that eight, nine ten billion is Overshoot-R-Us.

Fun fact:  People, livestock and pets dominate the overall picture of life on Earth. Homo sapiens with a total weight of 390 million metric tons, is slightly less than the weight of domesticated cattle which is 420 million metric tons.
Dogs rank fifth at 21 million metric tons but still constitute about as much mass as all wild land mammals combined.

Hanna's talk is 100% hopium.  She has not read up on Jevons paradox.  If she has she has not thought about it.  Hanna does not understand that when efficiency meets an exponential curve, the exponential curve wins.  Always!  The only way for humanity to endure, is to plant a new fruit tree in the garden of Eden! 

But that won't happen.  Modern culture has other ideas.  Modern culture wants to cut the penis off and go trans.  But going trans won't save shit.  Going trans will only confuse people and will provide no social benefit.  Other useless eaters will breed around trans as the movement goes the way of Shakers.

There is an advantage to being a long-term doomer.  Knee-jerk solution which are so attractive to a new doomer are seen as the empty promises they are. 

                William Stanley Jevons

Hanna is going to save the world by making sure wind and solar is cheap.  This is abysmal ignorance.  When the cost of using a resource decreases, it becomes more attractive for consumers and industries to use it. The increased affordability of a resource leads to higher consumption which offsets any initial gain in efficiency.

It is a contradiction.  People who become interested in the future are the same people who are most uncomfortable with the reality and mathematics of the actual situation.  Intelligent people are more facile with self-deception compounding the problem.  It takes about two years for a person to overcome hopium confirmation bias on average.  Some people never do.

Hanna is a data scientist with a severe case of confirmation bias.  How do I know?  Because she told us she is a data scientist, that is how. 

Hanna is saying she is right in a socially acceptable way so likely you did not pick up on it.  Credentials. 

Once we accept a person as an authority.  (I am a data scientist) we generally stop thinking about the substance of what they say and we simply accept it.  This is another hockey stick graph we have not seen I think, reason being: The more things get crazy the more people will be playing follow the leader and unfortunately any leader will do.  With leaders having an anti-populist agenda generally being more popular than boring politicians who have the best interest of the nation at heart.

Basic Al Bartlett stuff.  Al and others (Sid Smith) make a big deal about the day before an exponential growth event becomes painfully apparent, it is hardly noticed at all.

Hanna does not understand the energy density of fossil fuels and how their are no substitutes for fossil fuels given the overpopulated nature of a planet in overshoot.

Overshoot works like this.The character Mike Campbell in the 1926 novel "The Sun Also Rises" was asked about his money troubles and responded with a vivid description.

"How did you go bankrupt?" Bill asked.

"Two ways," Mike said. "Gradually and then suddenly."

Currently we be doing the gradual.

The last couple of decades have found me contemplating peak oil, global heating, biodiversity loss, etc, etc.

Could have spent more time focusing on the important ones, did anyone ever notice ANY of the peak oils just in this century?

Thus, it seems we just make up stuff to rationalise what we want to do.

You aren't the only one who noticed, years ago, that doom, any doom, was a great idea to justify buying hunting and fishing cabins, bug out bags, gold guns and ammo etc etc. The suggestion wasn't taken well, as it had to much truth in it, seemed to me. But now could be the time?

Humans are a species. Since humans are a species, we can't expect them to act in a non-species way.

Seems a bit self evident, your argument is that all the doomers didn't even realize they had forgotten they are just human, and therefore do all the stupid crap that got us into the mess we are in, and certainly aren't about to do what it takes to get out of it.

So denial of reality is really just a rationalisation of behaviour they have no real control over.

Sounds reasonable. Buy any doom at hand so going all bonkers over the hunting or fishing cabin, gold guns and ammo, etc etc. seems justified.

So some of us can be horrified by the inaction of most people to rein in their resource use but it makes no difference; humans will continue to act like a species.

Makes more sense to be specfic..humans will just continue acting like humans. Not all species are as stupid as we are.

So modernity will end, as it is unsustainable.

Would have been nice if everyone has jumped to this reasonable conclusion rather than dragging in all the nonsense they have over the years. Of course modernity will end, one way or another. After all, the Sun is getting lighter every day we've been talking about doom, and it won't ever stop until it has destroyed the planet.

Nature is a cruel place, contrary to hope of living in harmony with nature.

Nature isn't cruel. You are imposing a human perspective to it. Nature isn't human. Nature just does what it does, things stay in a general natural balance. Life, death, etc etc. Humans just had a better scheme to improve their geographic range to develop resources to keep breeding rather than..turtles....or goats.

The only real question is how long will it take for the resource and environmental problems we've created really bite home and make the inevitable decline of our species obvious?

Doesn't you talking about it mean it already has?

Not all species are as stupid as we are.

No idea how you would measure intelligence n order to prove that statement, but in terms of behavior based on the way the Predator-Prey cycle works and the way Bacteria reproduce, not only do all animal species continue multiplying exponentially until resources are exhausted or they are killed off, it goes across to the bacteria & insect kingdoms as well.  The only living organisms which don't seem to have an overpopulation problem are plants, but since they are generally stuck in one place and die off when the weather changes, you can't consider them very bright either.

You are quite right.  I have gone down this rabbit hole.

I read The Denial of Death by Ernest Becker a few years ago.  The first book I read all online.  The premise is that the avoidance of death is a more powerful drive than sex.  Freud went down the sex rabbit hole, but that does not explain the reality of the human condition.  Death anxiety is a far more powerful force.

We also have a podcast.

Denial of death, denial of collapse.  You got it.

Just in the last week a Netherlands court finally allowed a Dutch woman to commit Assisted Suicide despite being physically healthy.  She was autistic and despite years of therapy and drugs, suffered from constant depression.  Though legal on paper, they have a lot of roadblocks to prevent people from doing it who might change their minds or be cured somehow.  Her required treatments included electroshock therapy before they at last let a Dr Kevorkian help her pull the plug.

Far as taboos go for Christians, Suicide is even bigger than Original Sin of Sex.  Bigger than homosexual sex with a dog.  Express train ticket to hell.

Despite this really powerful social abhorrence of death, people contemplate suicide all the time, and the number of people who actually do pull the plug is steadily increasing as we move down the collapse highway.



add in drugs and booze, it's worse.

I don't agree that awareness of inevitable death invariably leads to the cessation of all rational thought. This is partly because there is no such thing as rational thought; it only seems there is. Without free will there can be no rational thought process. But also because I think I'm thinking rationally yet I know my death is inevitable.

We have will.  It is not free, but we can reach rational conclusions and act on them.  Having no free will is not the same as having no will at all.  My choice about giving two fucks about my rational conclusions is far from free, I agree.  But I still can reach rational conclusions, and if I enter into a feedback loop where I respect and seek rational conclusions.  I begin to be free.

Rational conclusions I am free to ignore.  Or not.  Depending on my will, even though it not be free. 

[RE]

Population size alone is not the determinant of sustainability. If that were so, krill, for one example, would be unsustainable. However, population size can make formerly sustainable behaviour unsustainable.

Krill have predators.  A million krill is a nice snack for a Blue Whale.  When they overpopulate and eat up whatever it is they eat, they die off, a few survive and ocean currents  blow them to a new neighborhood where they rinse and repeat.

Homo Sap is Apex predator on the planet now.  We've even defeated many of the microscopic predators which used to keep our numbers in check.  The only predator we have now is other Homo Saps.  However,WMDs present the possibility of war bringing death to everyone, you can't really win with them.  The small brush wars aren't a big enough killer to keep population in check, nor are even car accidents.  Our population has apparently responded to this by becoming unwilling to reproduce at replacement level.  How society will deal with this and the demographic problems attached are one of the big questions we face over the next 20 years.

There is no solution to humans being a species. No species is more stupid than any other; they are all acting like species. And, OK, nature is not cruel, since it doesn't care one way or the other. But the way most creatures would end their days might be considered cruel to our civilised way of thinking.

We don't need a solution to being a species, we need more dead people faster.  We'll get this solution one way or the other.  The only question is how far the knockdown goes before population stabilizes and rebounds.  The biggest death vector is likely to be famine.  That's our predator, other people eating food we need, then us killing those people.  Then the predator prey cycle takes over.

As there is no solution, the best we can hope for is that the shit really hits the fan after we're dead (hopefully dying peacefully in our sleep).

Personally, I hope to be alive long enough to say "I told you so", then be eaten for dinner by the CNAs here in the Gulag.

I don't agree that awareness of inevitable death invariably leads to the cessation of all rational thought. This is partly because there is no such thing as rational thought; it only seems there is. Without free will there can be no rational thought process. But also because I think I'm thinking rationally yet I know my death is inevitable.

Not everybody is irrational.  Plenty of rational people out there want to commit suicide.  If you're still living an OK life, you're not homeless, not in horrible physical or mental anguish, it's rational to want to live also.  But you don't stop driving your car, because nobody else is doing that, so society remains on a suicidal trajectory.

All of the approaches to our predicament that might help will have no impact, mainly because rational approaches would never be accepted by humans. In particular, only primitive living could be sustainable and that definitely is something people don't want.

You can't always get what you want, but sometimes you get what you need.

Of course I have an idea on how to measure intelligience, and no more need to prove it than you do. Personal preference works that way when it comes to statements with multi-dimensional and multi-species angles. Just as you have an idea on how you measure human intelligience (you tend to like people who know and can use the English language inside and out) I also have the same capability. And obviously it isn't just how well some knows English.

It's helpful if I can understand what someone is talking about to evaluate their intelligence, but it's not the only criteria.  I can't understand what dolphins squeak about, but I can tell they're brighter than tuna.  Behavior is a good indicator.  However, comparing human intelligence to that of other species is pretty tough, since besides the language constraints there are behavioral differences, environmental  differences and input/output limitations that make comparisons impossible.  Even though we know dolphins can use sonar to determine distances, we don't know how or if they use math to do it, for instance.  So saying some species are not as stupid as homo sap is anthropomorphizing them just as much as saying nature is cruel does so.  Your attributing a human quality of intelligence to other species.  It' not a provable assertion, and it's also irrelevant.

Fine. I will resist the urge to mention what a poor excuse for doom any of the past peak oils were.

So, other good doom scenarios tend to run towards some of those mentioned by Tony certainly. I am partial to gradual doom, climate change. Less so "here comes WWIII!!" doom. Economics is always a good local problem, with lower probability of being full scale take down the world issue. Saw an attempt in 2008, it was ugly as economic downturns are, but a doom? Eh. Pandemics? Have low probability potential, but there is always hope and anti-Fauchi angles.

Cosmic collisions and GRB's, lower probability but always good for some conversation, and far cooler than run of the mill "humans be stupid" stuff.

Lots of things aren't provable. So I'll go with humans being less intelligent than some species or another because humans have the ability to KNOW better....and do the stupid shit anyway.

Take two species, one knows better, one doesn't. The ones that know better do stupid shit regardless and die off. The others that don't know better, naturally fit within their world and system and can do it as long as the system endures. Naturally smarter because they lack the cleverness that dooms the stupid bipeds who can't see past their next dig it up, cut it down, burn it exercise.

T-Rex was the apex predator for millions of years. Humans and all their smartness will be lucky to break 2 orders of magnitude LESS time than that.

[RE]

So I'll go with humans being less intelligent than some species or another because humans have the ability to KNOW better....and do the stupid shit anyway.

SOME homo saps have the ability to know better, all do not.  I'm sure you're familiar with the concept in chemistry of a "rate determining step".  For those of you not familiar with this idea, it basically states that in a multi-step reaction, the speed of the reaction is governed by the speed of the slowest individual step.  When one step moves very slowly compared to all the rest, you can ignore all the fast ones because the overall rate at which the total reaction proceeds to completion is governed by the slowest step.

With society, you have individual intelligence, which can be amazingly brilliant in some people.  Collective intelligence though is only as good as the stupidest guys in the room.  The stupidity of a HUGE percentage of the population is breathtaking.  I give the example here of Terence Howard, the actor from the 1st Iron Man movie who played Tony Stark's best friend.  He was fired from this role, likely because he's a flaming idiot, which the casting director didn't pick up on when he was given the role.  It later probably surfaced because Terence has some thoroughly whack-a-doodle theories about math & physics and probably spouted off about them on set.  He's recently got a lot of publicity because Joe Rogan had him on his show to spout off on these ideas.  Here's a brief debunking of his idiocy.

The thing is, Joe Rogan's audience IS stupid enough to eat this shit up.  Just as MAGA crowds are stupid enough to eat up the shit that Donald #VonShitzinPants defecates from his mouth every day.  Collectively, Homo Saps are only as intelligent as the low grade morons who buy this drivel.  It doesn't matter how brilliant all of us geniuses who populate this website are  , the intelligence rate determining step is Joe Rogan's audience, not ours.

Far as T Rex long duration as Apex predator, it wasn't adaptable to many different environments or grow its own food supply.  I'd bet it followed the same Predator-Prey cycle as Lions do, which are Apex predators in their particular ecosystem.  When weather is good and the antelope the lions eat multiply, lions start multiplying and eat up the excess antelope.  Once they eat so many they're hard to find, lions die off from starvation until the next time the weather is good and the antelope breed up again.  Long as the overall climate doesn't change much, stable ecosystems like this persist for a long time. Everything is in balance, so it's sustainable.

Homo Saps lived this way during the H-G period,  which lasted from the emergence of the species ~300K years ago until the development of agriculture ~15,000 years ago.  If you include earlier versions ofthe genus Homo, we go back millions of years too.  Our "stupidity" in population overshoot is the paradoxcal result of our intelligence in being smart enough to develop metallurgy which allowed us to produce tools for doing large scale agricultural production of food.  The same metallurgical acumen gave Ag societies a big advantage over the H-Gs, who they proceeded to kill off over the last 15K years, leaving only the unsustainable ag version around.

Not satisfied with the speed at which we were turning the planet into desert just with ag, 275 years ago the geniuses of the era came up with the Steam Engine and numerous other inventions which made it possible to expand population even faster to even more relatively inhospitable places.  Other geniuses of the era like Mathus pointed out that if it continued we'd ultimately overrun the planet, but as a society these folks were ignored because the collective intelligence drew the conclusion steam engines are great, love those steamships and railroads, let's build more and better!

Sometime in the 1950s a few geniuses pointed out that so much of this burning was going on it was going to have some very nasty blowback in a few decades, but other geniuses told the vast majority of Joe Rogan viewers not to worry about this because 1st climate change wasn't real, then later that renewables could substitute.  Since this is what Joe Rogan viewers wanted to hear because it meant they could keep Happy Motoring, nobody listened to the geniuses here and other websites that told them, no, sorry, that dog won't hunt.  Our message is not as appealing to the collective intelligence as the message they get from Billionaires who tell them they should breed more kids to buy more Teslas.  Despite this message however, the simple fact most people can't afford to have more than 1 kid without a huge sacrifice to their own personal standard of living, they are choosing not to have the kids regardless of what Billionaires, their Church or Da Goobermint tells them.  In this case, Collective Intelligence is actually proving smarter than geniuses like Elon Musk.

Anyhow, as a species we're no smarter or stupider than other species, we operate within the same constraints of a finite planet and like all species we exploit the environment until the environment pushes back in one way or another.  No species voluntarily stops reproducing, it only happens if something in the environment changed enough to make reproduction a less appealing choice.  What changed?  Most significantly for homo saps in the industrialized countries, women had to go into the workforce of capitalism and leave the role of full time homemaker and baby factory.  It was painted as a "choice" and "Women's Liberation" by geniuses in the field of sociology, but appealed to women tired of the subservient role and being dependent on men.  I think most of those women still haven't grasped they just traded one form of slavery for another one.  In any case, it is slowing down the overshoot problem, but as noted by many comes with its own set of demographic problems.

The bottom line is regardless of the intelligence of ouur species, we will have a large population knockdown, the only questions are how soon before it really takes off, how fast will it be and what percentage of global population will be wipe out before it stabilizes?   There are too many variables to do any better than a WAG on this.  A blight of one of the major monooculture crops like corn, soybeans or rice could bring on a global version of the Irish Potato Famine in any given year.  A collapse of the Larsen Ice sheet or Greenland ice sheet could raise sea levels 3m in a single year. A collapse in the currency markets could slow global trade to a crawl.  The border crisis and northward migration from Africa-->Europe or SA-->NA could grow by a order of magnitude in 2 or 3 years.  Or you may just have slower deterioration on many fronts over the next decade.  All we can do is keep observing the progress until something pops up that will set off a cascade failure.  It could be as small as a Food Vendor setting himself on fire, or the assassination of a major political figure.  At some point on the timeline though, it will blow.  Everybody Knows.
