>The EPA recently lowered its PFAS guidelines significantly after discovering that the chemicals may affect the immune response in children to vaccines, Cousins noted.
That... still seems like an issue, to be honest. Not that you were saying it weren't, but... hmm. I wonder how much of a problem we're making for ourselves.
PFAS levels have gone down because we drink treated water. Making municipal water safe to drink is a big industry now. Anyone drinking only rainwater is exposed to those higher levels of whatever is in the rainwater. A small amount of rainwater is probably fine, but if you really do live off the grid year round then you need to treat your rainwater.
Certain technologies have been found to remove PFAS from drinking water, especially Perfluorooctanoic acid (PFOA) and Perfluorooctanesulfonic acid (PFOS), which are the most studied of these chemicals. Those technologies include activated carbon adsorption, ion exchange resins, and high-pressure membranes. These technologies can be used in drinking water treatment facilities, in water systems in hospitals or individual buildings, or even in homes at the point-of-entry, where water enters the home, or the point-of-use, such as in a kitchen sink or a shower.
Reverse osmosis water filtration systems that use activated carbon are pretty common, and least where I live. We have one under our kitchen sink, and so do my in-laws. Most refrigerators that include a water dispenser come with an activated-carbon-based water filter as well.
I live in a "developing nation" [0] of 70 million people whose private
water companies are fined billions every year because they cannot meet
the most basic standards of supplying potable water and not dumping
raw sewerage into the rivers and sea.
I’m not sure what point you’re trying to make anymore. You asked if people actually have these things. We do. Why does this need to scale? If you want to be pedantic, anyone can make themselves an activated charcoal water filter using fire, wood, half a plastic bottle and some rocks and straw and stuff. If you’re on the Internet you already have access to this knowledge.
In my area of the country most municipal water treatment systems don't have PFAS treatment. These systems are expensive to install and come with their own headaches.
That said, funding is now available to upgrade water treatment plants for PFAS.
> A small amount of rainwater is probably fine, but if you really do live off the grid year round then you need to treat your rainwater.
Drinking untreated rainwater is a pretty bad idea [1], even without considering PFAS. A bird pooping on the surface you collect it from is enough to contaminate the tank with bacteria, parasites and/or viruses, and if you collect any kind of ground run-off it gets significantly worse. [2]
It's worth noting that filters capable of removing PFAS are readily available (in the industrialized world). Apparently even regular activated charcoal filters do a good job.
A common model for chemical intake is based on the person's weight. I.e. if it's unsafe for the average human it's likely even worse for children, smaller animals, etc.
This would need to account for how much more or less of the chemical that the person consumes (e.g. children would likely drink proportionately less water all things considered)
In general, smaller organisms tend to consume more calories or resources per mass of body weight than larger ones. One reason, for mammals especially, is that maintaining homeostasis means scaling energy input with surface area, since that’s what radiates away heat. Surface area roughly scales with square of height, while mass scales with volume (cube of height).
> children would likely drink proportionately less water all things considered
Children tend to be more physically active, and have higher surface area to volume ratios, so proportional to body mass their water intake must be higher.
In a lot of places drinking water is pumped from open air aquifiers(a lake basically) so presumably it contains everything rain does, since it doesn't go through the rock layers.
Ultimately all water comes from the creation of the earth, which in turn got it from space. The ultimate origin is not very useful.
If we just want the first step before treatment plants, it depend on location. Generally it is what ever water that is cleanest and cheapest, usually lakes and rivers with the best connection and high flow of ground water. Ground water tend to be highly filtered which lowers the amount of treatment that treatment plants has to do.
Rainwater collection is usually not used for drinking water given the high amount of pollution. It can be used in industry/agriculture, or as backup for areas where the ground water is severely limited.
In the Boston area, our water comes from the Quabbin Reservoir. That's largely fed by rain, as far as I am aware. How much PFAS actually gets filtered out? Probably not much.
You can actually easily find this information online [0]
> PFAS compounds, used since the 1940s for
many purposes, from stain and waterproofing
to firefighting, continue to be a concern.
Tests of MWRA water show only trace
amounts of these compounds, too small
to be quantified, and well below the state
standard of 20 parts per trillion. MWRA results
are also well below recently proposed EPA
standards.
A lot of the world most certainly does, especially in rural areas that are not connected to water treatment plants. Bore water tends to be hard, so humans stick to the rain water when we can get it.
"I'm not super concerned about the everyday exposure in mountain or stream water or in the food. We can't escape it... we're just going to have to live with it."
I agree that it doesn't feel right to read a quote like, "I'm not super concerned about..." along with such a dire sounding headline.
All I know is that we're rapidly changing things that have been much more stable for thousands and thousands of years. Getting rid of aggressivity is good but if it takes your fertility/strength/bone density/dementia resistance/&c. with it... but then again is humanity a good thing ?
Testosterone doesn't directly cause aggression, it causes people to compete which may manifest as aggression if aggression leads to status in whatever culture you live in. - my recollection of Robert Sapolsky
He was reading an article about how chemicals we're dumping are triggering a frog species natural ability to change sex. The frogs normally do it when there's too many of one sex, to even it out, but the chemicals were making them switch when there was balance and were causing an imbalance.
Truth is stranger than fiction: it would have been more accurate for him to say "they're turning the frogs trans".
This is non controversial established medical fact. Here are the first three results when you Google 'testosterone rates dropping'
The only thing vague is the precise etiology. However, when it comes to legalizing irreversibly blanketing the planet in poisons, the onus should be on proving they are not the culprit, not the inverse.
'The average levels of the male hormone dropped by 1 percent a year, Dr. Thomas Travison and colleagues from the New England Research Institutes in Watertown, Massachusetts, found. This means that, for example, a 65-year-old man in 2002 would have testosterone levels 15 percent lower than those of a 65-year-old in 1987.'
'Research carried out on Finnish and Danish populations has shown the same trend [1,6]. And even more recently, a large-scale study of Israeli men has shown how average testosterone levels have dropped between 2006 and 2019 [7] — by over 10% across almost every age category. '
'Testosterone deficiency has a prevalence of 10%-40% among adult males, and 20% among AYA men aged 15-39 years, he added.'
a) nobody has tested my testosterone or my great grandpas to my knowledge
b) Both of those are taking drops over a certain period and then you're extrapolating back to my great grandad and assuming certain results, which is a bit tenuous. No to mention also assuming the cause.
Quite a long way away from a "non-controversial established fact."
we have 50% of the testosterone of our grandpas because body fat produces small quantities of estrogen, and we're the fattest, most sedentary, most in-doors-y humans in the history of humans.
The great thing about modern living is that a thousand variables have changed in the last 70 years so we can pick our own favorite pet peeve and just hammer on that point in every conversation.
Notably, we’re at record levels of sedentaryness in western society - and record levels of low sex.
Low sex IMO also partially due to high levels of narcissist abuse by society (and mothers) aimed at - well - everyone - coupled with little support or guidance on how to fight back.
Especially in younger folks.
Personally, I noticed schools phasing out recess, PT, and physical activity a long time ago. Steadily decreasing for almost 30 years. It’s gotten pretty bad, to the point now that many schools do almost none now. I’m sure everyone has noticed the ‘dads are incompetent losers’/predators schtick that’s been on TV for decades too.
The level of physical activity in most jobs has also been dropping.
Also, the widespread use of high SPF sunscreen, while likely reducing cancer rates, is also likely depressing vitamin D levels, in combination with the amount of sun most people are exposed is likely leading to subsets of the population (non supplementing) which seem highly correlated to neuroticism and mood regulation issues. [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4496526/]
Anecdotally, I’ve seen no decrease in sex drive among active folks - and any following of news from the olympic villages shows similar behavior.
If anything, there is a pretty clear correlation between activity/health/sex (or at least sex drive). And always has been.
Personally, I’ve noticed a very strong correlation between seasonal weather patterns (aka winter) and everyone losing their minds (more), especially online, especially the last few years - as everyone has stayed at home more, and people are online more, staying single more, etc.
The big issue with this kind of problem is that it can be self reinforcing. Contagious even.
The best thing to do is get outside into nature, get some sun, exercise/lift heavy things, and have some good sex.
Easier said than done though eh? Especially when there is so much ‘crabs in a bucket’ going on.
Maybe it’s caused by endocrine disruptors - they certainly aren’t helping, and we should do what we can to remove them. But the elephant in the room is that our society has shifted in exactly the way one would expect would cause these issues too. And it correlates with the various mental health issues that are going nuts as well.
If you look at the daily habits and attributes of the population 100 years ago on these elements vs today - they couldn’t be more different.
So society, we need to get out, workout, and get laid if we want to be healthy.
Baseline testosterone levels are actually even lower in most hunter gatherer populations. This suggests that your explanation is not necessarily correct.
It’s interesting how no real evidence was cited and how they state that levels in humans have dropped precipitously even though levels in the environment have not.
They attribute this to knowing that PFAS exist but that doesn’t really explain anything.
Maybe I’m missing something but this article (as written) seems like pseudo science.
> However, Cousins noted that PFAS levels in people have actually dropped "quite significantly in the last 20 years" and "ambient levels (of PFAS in the environment) have been the same for the past 20 years".
> "What's changed is the guidelines. They've gone down millions of times since the early 2000s, because we've learned more about the toxicity of these substances."
I think what's changed most is our standards. Used to be if you survived to reproduce, you were doing pretty good. Extra points if you got to watch your kids grow up. Now the standard is basically "Every substance that can be demonstrated to have worse health outcomes than its absence is toxic" - which on a technical level is true, and might even be what you care about, but you also need take a bigger-picture perspective and weigh it against all the other risks of ordinary living you face.
I feel like that's taking the commenter's quote out of context, or at least missing the point. They aren't arguing that PFAS aren't everywhere, or even that they aren't harmful. They're arguing that, in the grand scheme of things, the harm produced by PFAS to humans is relatively inconsequential, especially when you consider all the improvements that technology, broadly, has brought to the human condition.
To emphasize, I think that point is very debatable, but I don't know enough about the real harms of PFAS to comment. But I do think it's valid to have a substantive debate on the true harms of PFAS, even if the other side of that debate is that comparing ourselves now to a time when the majority of kids died is the wrong yardstick.
I went and did some research, and have a friend who's a material scientist. The harms of PFAS are pretty substantial. Teflon is nasty; if you can do without it in your cookware, you probably should.
However, statistically the things that are most likely to prevent you from passing on your genes are:
1. Not making enough money.
2. Anxiety/depression
3. Drug overdoses
4. Car accidents
5. An unhappy family life
6. Swimming pools
And on that list of offspring averted, PFAS basically don't register. You are much better off making sure you get into a good career, talking to your kids about drugs, being very careful when you drive, and otherwise not sweating the small things than obsessing about forever-chemicals in the atmosphere.
What is remarkable here is that every single thing you say is correct.
Everything on your statistical list looks right, and can probably be
proven by a stack of peer-reviewed scientific studies from medicine,
sociology, psychology...
And yet as an argument, it's worthless. Worse... it's dangerous.
Because in your schema, the impact of climate change, pollution and
other threats that will end this species each rank as zero! You get
to "pass on your genes" merely to consign a few hundred of your
descendents to a miserable death.
This is the tyranny of instrumental reason that you so cleverly use
against the goal (reproduction of genes) that you purport to champion.
None of the above are actually expected to end the species. Not in anyone's lifetime, given the range of climates humans survive in. We might end up with a 90% reduction in population but Short of a massive asteroid impact or massive solar event it's pretty hard to imagine wiping out the entirety of humanity.
I agree. But anything causing even a 10% population decline over a short period of time would have insane second order effects (e.g. nuclear war) as we fight over control of resources.
> it's pretty hard to imagine wiping out the entirety of humanity.
That's kinda my complaint here. Imagination is more important than
knowledge. If we started much earlier in education explaining to kids
how remarkable and fragile our existence is, how intricately
interconnected we are with nature, birds, bees, mushrooms and
microbes, then maybe Hollywood disaster movie plots wouldn't seem like
the only route to the end of humanity.
With only 10% of the population, we might find so much institutional knowledge lost that the remaining just can't feed themselves. We'd have to relearn hunting and gathering, and that just might not happen.
If we have to relearn hunting and gathering, that's not even closely compatible with feeding 10% of current human population, that's consistent with <1%, probably 0.1% or less of current population surviving. Feeding even 0.8 billion people still requires intensive mass agriculture.
Arguably climate change risk comes under #1 (not making enough money), because in the most likely climate change scenario, people above a certain wealth threshold will probably survive.
Not saying this will be a pleasant experience. Billions may starve. But that still leaves billions, and the purely mercenary reality is that money is what puts you on one side of that dividing line or the other.
From a certain perspective maybe. But I think that would be one
coloured by a narrow mentality [0]
In a "purely mercenary reality", what you need to survive is not
wealth, but peace, and that is something you cannot buy with many of
the futures we're now looking at.
In a funny way, PFAS is a great metaphor. Forever chemicals have now
been found in places nobody would ever have predicted. Bad things have
a way of spreading in ways you won't see until they're at the gate.
It might not be a good idea to bet the farm on isolationism and
exceptionalism.
I'll go out on a limb and say that 99% of the people buying "Glide" dental floss at COSTCO have NO IDEA that they're coated in toxins (PFAS) and if they pick up a gargantium bag of Cheerios for their kids they also probably aren't aware that those too are coated in Chlormequat chloride. Modern living.
> Cheerios for their kids they also probably aren't aware that those too are coated in Chlormequat chloride.
From Wikipedia:
> Chlormequat has not previously been registered for use on food crops in the United States. In April 2023, the U.S. Environmental Protection Agency proposed allowing the use of the chemical on food crops such as barley, oat, triticale, and wheat. The EPA’s human health risk assessment indicated "no dietary, residential, or aggregate (i.e., combined dietary and residential exposures) risks of concern." No risks were identified by EPA to aquatic species of invertebrates, vertebrates, and plants in addition to terrestrial plants.
That phrasing suggests that Cheerios are intentionally coated with Chlormequat which doesn't appear to be the case. Instead, tthe grains used to manufacture Cheerios are treated with Chlormequat (though, arguably, any food product utilizing those grains would have the same issue, I'd assume). Might not make anyone feel any better, but different issue.
"Chlormequat was detected at low concentrations in samples from 2017 through 2022, with a significant increase in concentrations for samples from 2023. We also observed high detection frequencies of chlormequat in oat-based foods. These findings and chlormequat toxicity data raise concerns about current exposure levels, and warrant more expansive toxicity testing, food monitoring, and epidemiological studies to assess health effects of chlormequat exposures in humans."
...
"Despite being approved for use on crops in Europe and parts of North America, chlormequat exhibits concerning toxicological properties, as documented in historical as well as more recently published laboratory animal studies. In the early 1980s, the impacts of chlormequat exposure on reproductive toxicity and fertility were first described by Danish pig farmers who observed reproductive declines in pigs raised on chlormequat treated grains [4]. These observations were later investigated in controlled laboratory experiments on pigs and mice, whereby female pigs fed chlormequat treated grain exhibited disrupted oestrus cycling and difficulty mating compared to animals on a control chlormequat-free diet [4]. Additionally, male mice exposed to chlormequat via diet or drinking water during development exhibited decreased fertilization capacity of sperm in vitro [5]. More recent reproductive toxicity studies on chlormequat show delayed onset of puberty, reduced sperm motility, decreased weights of male reproductive organs, and decreased testosterone levels in rats exposed during sensitive windows of development, including during pregnancy and early life [6,7,8]. Developmental toxicity studies also suggest that chlormequat exposure during pregnancy can dysregulate fetal growth and metabolism [9]. Other investigations did not find impacts of chlormequat on reproduction in female mice, male pigs, or a subsequent investigation of fertilization capacity in male mice developmentally and postnatally exposed to chlormequat [4, 10, 11]. Equivocal evidence in the toxicological literature on chlormequat may be due to differences in doses tested and outcomes measured as well as selection of model organism and the sex of laboratory animals. Consequently, further investigation is warranted."
> I'll go out on a limb and say that 99% of the people buying "Glide" dental floss at COSTCO have NO IDEA that they're coated in toxins (PFAS)
Thanks for making me aware of this. I've been trying to make a point of avoiding PFAS, but it seems to be everywhere.
> The study found that women who flossed with Oral-B Glide floss had higher levels of a chemical called perfluorohexane sulfonic acid (PFHxS) in their blood than women who didn’t use that type of floss.
I've been in the same camp, mostly against BPA (and it's analogs) and PFAS. It's amazing how casually they are used in consumer products, even by brands who carry marketing that is nauseatingly "save-the-earth-happy-healthy-eating".
Another one is nitrites in processed meat. All the fancy "health conscious" brands proudly state "NO NITRITES!", but then those ass hats put in a bunch of celery salt...which is just nitrites with a different name.
Note: For anyone curious, trader joes actually does sell a bacon with no nitrites of any form. First and only time I have seen it.
Comparing nitrites (which occur naturally) with PFAS and other "forever chemicals" is off the board.
To my understanding the observed and very real ill-effects of toxic bacterial excretions due to nitrites being phased out in lunch-box products (sliced ham, salami) here in the EU far outweigh any possible effects of the nitrites. Source: reddit comments that seemed legit.
> All the fancy "health conscious" brands proudly state "NO NITRITES!", but then those ass hats put in a bunch of celery salt...which is just nitrites with a different name.
Marketing that takes into accounts biases of particular target group. That particular case is, I think, becoming common: since large fraction of the population is irrationally afraid of anything that has numbers in its name, whether as digits or words in any language, the companies look for whatever plant they can pull that specific substance from, and use that in production process - possibly compromising quality and efficiency, but allowing them to write ${good natural plant} in the ingredient list instead of evil E-number or satanic 6-6-hexa-whatever.
I'm conflicted about this practice. On the one hand, I hate pulling wool over other people's eyes; on the other hand, I also hate reflexive fear and anti-intellectualism of our society.
I would hazard to say that PFAs and microplastics are safer than lead and mercury but less safe than not having them at all, but only with the caveat that I believe there's got to be some sort of Zeno's Paradox correlation with environmental human health and safety.
To wit:
People used to do all sorts of self-harming things not knowing any better and now we do fewer of them.
The Romans used to sweeten their wines with powdered lead. The ancient Chinese alchemists used to make elixirs of immortality out of mercury compounds and feed them to their wealthy.
I'm not saying things are good now and that we shouldn't push for them to be better, not by any means.
Rather I am saying that as we take further steps towards optimal human health, aligning our common environmental encounters with our biology, we should remember that the effort people have put in to get us this far is only going to take us half as far the next time, and half again the time after.
And that is all well and good, progress is progress, right?
However, does it not seem like the smaller the flaw we find the more we get upset about it?
I believe this phenomenon is caused by a continuing delusion that we were once ever perfect, that we ever lived in harmony with nature, that there is some paradisian SI Garden of Eden unit we can measure our present environment against, and that the current state of events is the face of our fall from grace and must be destroyed like the monster it is.
I believe the truth is things have never been better in hundreds of ways, and they're going to keep getting better as we repent of our past mistakes and learn more about what mistakes we are still currently making, and that the world 25 years from now will be as different a world as the world of today is to the world of 1999.
The secret, and it is a secret, is to understand everything that you've just written, and quietly let the machine worry on.
That collective handwringing (set in eternal struggle as it is with financial greed) is what got us here, and it's what will get us the next 50% and the 50% after that. Wink and enjoy the ride.
...I'd like to think that we can do a bit better than that. The world could have done without things like Tetra-Ethyl-Lead, Thalidomide, and all the other fd things we've ended up with as a result of just letting the machine whirr on. We need to recognize that perverse incentives exist, the system is vulnerable to them, and as our technical prowess increases, the consequences of even one lapse are becoming larger and broader in scale beyond, in some cases, our ability to handle it by just winging it, and not* applying some level of precautionary principle.
How am I supposed to keep track of things like this? Between all the chemicals, boycotts, etc etc etc I don't know how I'm supposed to use any modern product again. (Or primitive product, for that matter.) It's honestly driven me to apathy. I just don't have the bandwidth to worry about it.
A high-fibre diet is supposed to help, as fibre can absorb toxins. To what extent I don't know. So, make your own sourdough wholewheat bread. And eat plenty of greens like broccoli, cabbage . I guess the greens are sprayed with stuff too though. As is the wheat in the bread. The fibre might counteract the effects of the sprays somewhat.
Except this isn’t true. It’s made of PTFE, which hasn’t been made with a PFA process in 15 years and is itself one of the most non reactive substances known unless you heat it to very high temperatures.
The entire right side of the periodic table is composed exclusively of forever chemicals by this definition.
Non-reactive also means doesn’t interact chemically with other chemicals, which is a desirable thing in a plastic that might be ingested. While maybe not awesome that it sits in silt not reacting to the end of time, if it also doesn’t react with anything in your body, it’s safe to take into your body, no?
The problem with some PFAS is they don’t readily degrade but they’re biologically reactive and interact with the bodies chemistry. That’s not a great feature. But it’s a huge class of chemicals, all of which are chemicals stable due to their carbon fluorine bonds - one of the most stable bonds in nature. But that doesn’t mean they can’t react in ways that don’t break the molecule apart, or form other chemicals that maintain the integrity of the C-F bond.
But it also doesn’t mean that they DO react.
Life isn’t so simple it can be reduced to a mantra like “plastic bad” or whatever. PTFE has a lot of very useful characteristics, and its lack of reactivity in the body isn’t the least of them.
It’s not clear which part of the comment you meant when you said it’s not true, but PTFE is a PFAS, exactly how toxic it is or isn’t I don’t think is well known yet but people have been living with PTFE implants.
The toxicity of Glide. PFAS is a very broad class of chemicals. The toxic PFAS associated with PTFEs are PFOA and PFOS, both of which were phased out in production in the 2010s.
Whenever this topic of Glide being toxic comes up they cite this article :
Which is based off blood samples drawn in 2010-2013, which is at the time PFOA was being phased out of the PTFE production process due to lawsuits around the PFOA toxicity, which DuPont was aware of. The new process using GenX (seriously), which is known to cause problems too but at a lesser extreme than PFOA. However the issue with PTFE was with the residuals of PFOA which you don’t find in commercial PTFE for GenX.
And yes, PTFE is widely used in medical implants and devices.

WTAF is it with this "noble savage" glorification of mythical past
miseries as a way to avoid thinking about how massively we've screwed
up as a civilisation? That sort of response is a "Don't look up" level
of avoidance and rationalising.
I actually think this is the opposite of noble savage imagery, and that's actually what you're doing. They're not saying things were better in the past when technology was more primative, you're the one saying that the past was better and that getting to where we are now how we have is "screwing up" something (presumably a good thing that existed in the past that is no longer present).
All of those commenters deconstructing my clumsy use of "Noble Savage"
(I admit it's not quite the right thing) - are indeed (maybe wilfully)
missing the point.
A better expression might be the "Parochialism of the present". But
that doesn't quite get to it. Nor even Thomas Hobbes' flowery and
overblown conceit of past life as "Nasty, brutish and short".
It's about a phenomenon of lionising a one dimensional idea of
"progress" in a patently self-deceiving way.
Noble savage doesn't mean that you think the environment of the past was better than the present, it means that you think the people were better before being corrupted by civilisation. I.e. it's about thinking that the changing environment under progress corrupts humans, which is the opposite of what the person you are replying to is saying and is exactly what the person they're replying to is saying...
Noble savage = humans fundamentally corrupted by civilisational progress
I think "bad tradeoffs" is the term you're looking for. If you think the negative outcome has infinite negative value, there's not really a lot that can be said to that as it becomes a Pascal's wager.
If you don't acknowledge any of the tradeoffs involved in pollution and instead just make a point about harm in a vacuum, it's hard to know how to consider it.
No, I think everyone recognises tradeoffs here and your belief that
I'm creating a dichotomy is unwarranted. I'm addressing distorted
perception of the parameters of tradeoffs.
Like the overwhelming exceptionalism of how we all care about the
environment and the future health of our children... just don't take
our gas-guzzling cars and non-stick pans way!
We are not rational beings, but we so deeply believe we are.
Im on my 4th electric car, every single one has been remarkable in terms of cost, build quality, innovation etc.
If the cybertruck was out a year earlier, I suspect I know a few people driving "gas guzzling" trucks that would have bought that instead, because it would have been cheaper, faster, and in almost every measurable and unmeasurable quality, better.
Why do you think people will forever hold on to ICE? It strikes me that electric cars are a step change in almost every way, maybe the reason people still have ICE is they didnt have a compatible electric alternative at the time.
The way these people talk about the past makes it sound like people in the past were somehow perfectly stoic in the face of discomfort or disease, but it's extremely easy to find historical documents showing that this isn't the case. I think the reason people fall into this "noble savage" trap is because they (rightfully) can't imagine living without modern technologies like refridgerators and flushing toilets, and therefore (wrongfully) conclude that the people in the past were simply more rugged to be able to live without it.
Also, as you say, it's an easy way to explain away our problems, to say that people in the past were better and if they were here today then they wouldn't be complaining like we are.
I think the parent comment made a reasonable point and did so in a calm manner. It in no way overplayed the misery of the past (I'd argue it vastly underplayed it).
Now, to your contention that "we've screwed up as a civilisation". What do you mean exactly? What civilization and when did the screwing up start?
> I think the parent comment made a reasonable point and did so in a calm
manner.
As I have pointed out in other remarks here today, calmness
reasonableness do not make a bad position good. If anything they add a
palatable veneer to the harm.
> It in no way overplayed the misery of the past
I completely disagree. The idea that in the past people were "lucky to
see their children grow up" is dramatic, and a tautology anyway since
we are all "lucky" to see our children grow up in any epoch. It
paints a needlessly bleak picture of some awful past that
technological progress is implied to have eliminated with justifiable
costs.
> What do you mean exactly? What civilization?
Actually, you know what. You're right [0].
"What do I think of Western civilisation? I think it would be a very
good idea."

You got me there, I do think the costs for (almost) eliminating famine and diseases with double-digit mortality rates are justifiable. That said you didn't really answer my question, but I'll roll with it.
Consider the extinction of megafauna [0], the deforestation of China [1] or Mesopotamian farming practices [2]. It would be hard to blame these on Western civilization (real or imagined). I'd say we have been operating in the same unsustainable way for a long time. I wish it were otherwise because it would make everything easier.
It started when science and technology changed from something we do,
into something we believe in.
I don't think that actually happened any time around the Enlightenment
of even the Industrial Revolution, but we're definitely deep in it
now. I'll leave you to put the pin in the map.
Also, the cause and effect are not so simple. It's not as if we
changed our culture and beliefs, and then embarked on a century of
planet-destroying madness. Rather, like the sunk-cost bias of an
addict, we realised we are on a bad road, labelled that as

Sorry to hear that's what's eating you my friend [0]. Just hit the
Xanax, heh? But as soon as you feel well come and join the rest of us
working on making things better.
This is at best an incomplete, complacent position to take.

Used to be.
And if you were lucky, you lived in a stable democracy instead of any one of the variants of violent dictatorship.
Fertility levels are in steep decline. Today's children will grow to adulthood in a world abused to the point of global disaster. [3]
Things have changed for the worse in ways that our species has never before faced.

This question of "facing things" is what bothers me. Sure, science and
technology is difficult and has awful side effects. Progress is a
complex vector, and it isn't easy to have 'purpose' (telos) see where
we should be going.
But what I see here every day is very intelligent, witty, well read
people ... using their intelligence against themselves. The
extraordinary intellectual acrobatics of denial and apologetics just
makes me weep. And so many who just down-vote challenging questions
but lack the patience and courage to form an argument.
Just been thinking about your remark about "gray". Like am I really so
dull? Wow! I just realised that people who use some regular browsers
see down-voted comments as kinda faded out. That's really sinister but
also quite funny and in character with the dystopian creed.
How about adding random characters and line noise to unpopular
comments, or replacing odd words to make them seem more deranged and
subtract credibility? That wo ld g1ve the "hacker-like" #eel 00f

this is a lame attempt to flatter our intelligence but then criticize for not engaging on what are essentially marketing platforms where the stakes are usually zero, and there is no way to demonstrably prove that we're not shills, morons, or GPT bots.
and IVF works. (yes, it's a bit more risky than the Nike method - just do it, yes, it's expensive, but having kids is a lot more expensive usually.)
the linked BBC article seems to contradict its title ("For the majority of men with fertility problems, the cause remains unexplained")
also, mixing up ability and willingness to have kids is just fucking revolting. of course a lot of people are don't have kids, because bad journalism takes away people's joy. well, also this little thing called ladder pulling, and the usual coordination problems (NIMBYs, etc)
It's true but other risks are usually discrete. PFAS exposure continously decreases your health while driving a car has no effect on your health until you get into an accident.
The risk calculation feels different in those cases.
Lots of deliberately-missing-the-point by crusaders posting to your point, @nostrademons. Yes it's bad there's plastic in rainwater, they bang on about that like they've thought of something you missed.
But I agree we live with so many other risks, there may conceivably be better windmills to tilt.
Heart disease dominates the US health problems. Maybe we could do something about food in America. Something we can actually do something about, with a measurable improvement in living.
Sure; but not related to health in the same way as the egregious use of fats and sugar. Start with first-order causes of health issues, then when that's dealt with move on to second-order and so on.
I mean, are you arguing this is somehow a bad development?
“Sorry kid, but at least your dad got to see you ride your first bike, chalk that up to win, used to be much worse! You know, DuPont and 3M can’t give ground all the time.”
It is very hard to read about the cancer clusters in WV/OH around the heavy PFAS sites and not feel some extreme disgust at how bad it got and feel thankful that this is getting significant attention.
In the Netherlands we have Chemours, they produce and dump PFAS. So naturally we find PFAS in and around the factory in Dordrecht NL. We find 13.000 x the norm in certain "swimming" waters. And naturally we find it the eggs of hobby chickens (not industrial ones)... So people stop eating fresh eggs. Many get rid of their chickens. But wait... As it turns out we find PFAS/PFOS that aren't even produced nor used by Chemours! What gives? We investigate and we find it all over the country. Some are above the norm, some below.
How does it get into the chickens? No one knows atm. The rain? The food? It seems like the stuff is just everywhere indeed. We also stopped eating our eggs, looking for a testing service.
I mean the answer about the chickens is obviously the water and the food. Mass produced chicken feed is garbage and I guarantee you your chickens are not fully pasture raised. And even if they were, all of your crops and fields are sprayed with chemicals. And, yeah, PFAS rain.
This gives a new spin on the question, what does rain taste like?
(I don't remember if that was part of the books too, but in the show The Expanse, a major character who was born and lived on Ceres pondered this occasionally. In the end, he was told by an Earther that "it tastes like nothing, it's just water". I guess this is an improvement over status quo.)
If anyone were to collect the major PFAS/microplastics/foreverchem threads from HN, I bet the list would be even more mammoth than the tax-filing perennial for which I had to convert the "related" list into continuation-passing style: https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...
Safety is not Boolean. Things are not safe or unsafe. It's just a question of HOW safe something is, what the risks are, etc.
Do we have any sense of the actual amount of PFAS in rainwater, and the human health impact of such? I didn't see any mention of this in the article. Maybe more investigation along these lines would be helpful.
As noted in the article, the EPA recently lowered the "safe limit" based on evidence that the previously acceptable levels were still high enough to reduce vaccine efficacy in children.
And we already know PFAS impact fertility and hormones, can cause some cancers, etc.
The only way water after being distilled by the sun to pure H2O can be contaminated with these chemicals is if the chemicals are in the air. To my knowledge, we have zero regulations on what airplanes are allowed to spray into the atmosphere. Scientists at https://www.geoengineeringwatch.org/ and https://climateviewer.com/ have tested the aerosols and other chemicals being sprayed and found them to include a number of harmful chemicals. If enough people were aware of what is going on, we could demand some transparency and accountability.
Fuel additives in any vehicle can put stuff in the air. If you look at these sites to see what they are intentionally spraying into the atmosphere, you will never look up at the clouds and airplanes in the same way.
PFAS boiling point is around 189 Celsius, so it can also evaporate with water - of course very slowly, but it's enough to simply get everywhere on Earth
This is a bit exhausting. I care about the environment. And I care about it's impact on humans. But I feel like it's a never-ending march of things to fret about. It really seems like folks are looking for thins to sound the alarm about.
Maybe PFAS really are a major problem, I don't know. But I'd love to see a bit more circumspection about this and other issues. Keeping people on red alert, all the time, about everything - does not seem like a recipe for human flourishing overall. Though it may be a good way to keep people under control.
> Keeping people on red alert, all the time, about everything - does not seem like a recipe for human flourishing overall.
It would help if we had some sort of mechanism to turn these "alerts" into action, which seems to be a sticking point for a globe dominated by society obsessed with corporate liberties to do nothing or double down on the problematic behavior.
You are exhausted. That doesn't mean the concern isn't well considered by those who are presenting it. The problem is your emotional fatigue, not that people are insufficiently "circumspect".
PFAS is just the currently hyped and talked-about symptom of reactive regulation.
The problem is that there's no requirement for demonstration of safety for new products/chemicals, not even monitoring, nothing (in most parts of the world). Which seems obviously bad.
But we currently live in a particularly idiotic mass-communication by memes times, hence we have defund the police and PFAS, and so on.
I hope this is the last nail in the coffin of "Better living through chemistry™." Just because we can make it (and make money from it) doesn't mean we should.

[ 5.8 ms ] story [ 250 ms ] threadThat... still seems like an issue, to be honest. Not that you were saying it weren't, but... hmm. I wonder how much of a problem we're making for ourselves.
But, as the article noted, PFAS levels in humans are steady for now. So, the damage is probably already done.
Actual ones. Actual ones in use right mow in your neighborhood? In use on the water you're drinking today?
But at scale? For the rest of us?
I live in a "developing nation" [0] of 70 million people whose private water companies are fined billions every year because they cannot meet the most basic standards of supplying potable water and not dumping raw sewerage into the rivers and sea.
[0] https://www.theguardian.com/commentisfree/2013/dec/09/britai...
That said, funding is now available to upgrade water treatment plants for PFAS.
Drinking untreated rainwater is a pretty bad idea [1], even without considering PFAS. A bird pooping on the surface you collect it from is enough to contaminate the tank with bacteria, parasites and/or viruses, and if you collect any kind of ground run-off it gets significantly worse. [2]

Sounds like a reverse osmosis filter works best.
Children tend to be more physically active, and have higher surface area to volume ratios, so proportional to body mass their water intake must be higher.
Airports are notorious sources, PFA's were used in fire fighting foams for a decade or more (depending on global location).
If we just want the first step before treatment plants, it depend on location. Generally it is what ever water that is cleanest and cheapest, usually lakes and rivers with the best connection and high flow of ground water. Ground water tend to be highly filtered which lowers the amount of treatment that treatment plants has to do.
Rainwater collection is usually not used for drinking water given the high amount of pollution. It can be used in industry/agriculture, or as backup for areas where the ground water is severely limited.
> PFAS compounds, used since the 1940s for many purposes, from stain and waterproofing to firefighting, continue to be a concern. Tests of MWRA water show only trace amounts of these compounds, too small to be quantified, and well below the state standard of 20 parts per trillion. MWRA results are also well below recently proposed EPA standards.

"I'm not super concerned about the everyday exposure in mountain or stream water or in the food. We can't escape it... we're just going to have to live with it."
I agree that it doesn't feel right to read a quote like, "I'm not super concerned about..." along with such a dire sounding headline.
Truth is stranger than fiction: it would have been more accurate for him to say "they're turning the frogs trans".
The only thing vague is the precise etiology. However, when it comes to legalizing irreversibly blanketing the planet in poisons, the onus should be on proving they are not the culprit, not the inverse.
'The average levels of the male hormone dropped by 1 percent a year, Dr. Thomas Travison and colleagues from the New England Research Institutes in Watertown, Massachusetts, found. This means that, for example, a 65-year-old man in 2002 would have testosterone levels 15 percent lower than those of a 65-year-old in 1987.'
'Research carried out on Finnish and Danish populations has shown the same trend [1,6]. And even more recently, a large-scale study of Israeli men has shown how average testosterone levels have dropped between 2006 and 2019 [7] — by over 10% across almost every age category. '
'Testosterone deficiency has a prevalence of 10%-40% among adult males, and 20% among AYA men aged 15-39 years, he added.'
b) Both of those are taking drops over a certain period and then you're extrapolating back to my great grandad and assuming certain results, which is a bit tenuous. No to mention also assuming the cause.
Quite a long way away from a "non-controversial established fact."
Weight lifting increases it more than cardio.
[https://www.nm.org/healthbeat/healthy-tips/fitness/quick-dos...]
More activity, and more muscle, leads to more testosterone.
More fat leads to more estrogen (and some other problematic hormones for men) - [https://www.betterhealth.vic.gov.au/health/healthyliving/obe...]
We’re a nation in the midst of an obesity epidemic.
Also, sex also seems to increase testosterone. Participating much more than watching. For both genders. So more sex == more sex, generally.
[https://www.medicalnewstoday.com/articles/325418]
Notably, we’re at record levels of sedentaryness in western society - and record levels of low sex.
Low sex IMO also partially due to high levels of narcissist abuse by society (and mothers) aimed at - well - everyone - coupled with little support or guidance on how to fight back.
Especially in younger folks.
Personally, I noticed schools phasing out recess, PT, and physical activity a long time ago. Steadily decreasing for almost 30 years. It’s gotten pretty bad, to the point now that many schools do almost none now. I’m sure everyone has noticed the ‘dads are incompetent losers’/predators schtick that’s been on TV for decades too.
The level of physical activity in most jobs has also been dropping.
Also, the widespread use of high SPF sunscreen, while likely reducing cancer rates, is also likely depressing vitamin D levels, in combination with the amount of sun most people are exposed is likely leading to subsets of the population (non supplementing) which seem highly correlated to neuroticism and mood regulation issues. [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4496526/]
Anecdotally, I’ve seen no decrease in sex drive among active folks - and any following of news from the olympic villages shows similar behavior.
If anything, there is a pretty clear correlation between activity/health/sex (or at least sex drive). And always has been.
Personally, I’ve noticed a very strong correlation between seasonal weather patterns (aka winter) and everyone losing their minds (more), especially online, especially the last few years - as everyone has stayed at home more, and people are online more, staying single more, etc.
The big issue with this kind of problem is that it can be self reinforcing. Contagious even.
The best thing to do is get outside into nature, get some sun, exercise/lift heavy things, and have some good sex.
Easier said than done though eh? Especially when there is so much ‘crabs in a bucket’ going on.
Maybe it’s caused by endocrine disruptors - they certainly aren’t helping, and we should do what we can to remove them. But the elephant in the room is that our society has shifted in exactly the way one would expect would cause these issues too. And it correlates with the various mental health issues that are going nuts as well.
If you look at the daily habits and attributes of the population 100 years ago on these elements vs today - they couldn’t be more different.
So society, we need to get out, workout, and get laid if we want to be healthy.
They attribute this to knowing that PFAS exist but that doesn’t really explain anything.
Maybe I’m missing something but this article (as written) seems like pseudo science.
> "What's changed is the guidelines. They've gone down millions of times since the early 2000s, because we've learned more about the toxicity of these substances."
I think what's changed most is our standards. Used to be if you survived to reproduce, you were doing pretty good. Extra points if you got to watch your kids grow up. Now the standard is basically "Every substance that can be demonstrated to have worse health outcomes than its absence is toxic" - which on a technical level is true, and might even be what you care about, but you also need take a bigger-picture perspective and weigh it against all the other risks of ordinary living you face.
PFAS didn't exist 75 years ago. Now we've almost permanently contaminated our environment and atmosphere with it, that's quite a big change.
To emphasize, I think that point is very debatable, but I don't know enough about the real harms of PFAS to comment. But I do think it's valid to have a substantive debate on the true harms of PFAS, even if the other side of that debate is that comparing ourselves now to a time when the majority of kids died is the wrong yardstick.
However, statistically the things that are most likely to prevent you from passing on your genes are:
And on that list of offspring averted, PFAS basically don't register. You are much better off making sure you get into a good career, talking to your kids about drugs, being very careful when you drive, and otherwise not sweating the small things than obsessing about forever-chemicals in the atmosphere.Everything on your statistical list looks right, and can probably be proven by a stack of peer-reviewed scientific studies from medicine, sociology, psychology...
And yet as an argument, it's worthless. Worse... it's dangerous.
Because in your schema, the impact of climate change, pollution and other threats that will end this species each rank as zero! You get to "pass on your genes" merely to consign a few hundred of your descendents to a miserable death.
This is the tyranny of instrumental reason that you so cleverly use against the goal (reproduction of genes) that you purport to champion.
I think the point is 100-300 years (maybe longer?) from now things might reach a tipping point.
That's kinda my complaint here. Imagination is more important than knowledge. If we started much earlier in education explaining to kids how remarkable and fragile our existence is, how intricately interconnected we are with nature, birds, bees, mushrooms and microbes, then maybe Hollywood disaster movie plots wouldn't seem like the only route to the end of humanity.
Not saying this will be a pleasant experience. Billions may starve. But that still leaves billions, and the purely mercenary reality is that money is what puts you on one side of that dividing line or the other.
In a "purely mercenary reality", what you need to survive is not wealth, but peace, and that is something you cannot buy with many of the futures we're now looking at.
In a funny way, PFAS is a great metaphor. Forever chemicals have now been found in places nobody would ever have predicted. Bad things have a way of spreading in ways you won't see until they're at the gate. It might not be a good idea to bet the farm on isolationism and exceptionalism.

That helps, but there are more participants in traffic than just you.
From Wikipedia:
> Chlormequat has not previously been registered for use on food crops in the United States. In April 2023, the U.S. Environmental Protection Agency proposed allowing the use of the chemical on food crops such as barley, oat, triticale, and wheat. The EPA’s human health risk assessment indicated "no dietary, residential, or aggregate (i.e., combined dietary and residential exposures) risks of concern." No risks were identified by EPA to aquatic species of invertebrates, vertebrates, and plants in addition to terrestrial plants.
So probably not coated in it.
... unless you regularly eat more than 85,000 tons of oats.
Between muesli in the summer and oatmeal in the winter I'm averaging close to that, but I exercise a lot so I got that going for me.
https://www.nature.com/articles/s41370-024-00643-4
"Chlormequat was detected at low concentrations in samples from 2017 through 2022, with a significant increase in concentrations for samples from 2023. We also observed high detection frequencies of chlormequat in oat-based foods. These findings and chlormequat toxicity data raise concerns about current exposure levels, and warrant more expansive toxicity testing, food monitoring, and epidemiological studies to assess health effects of chlormequat exposures in humans."
...
"Despite being approved for use on crops in Europe and parts of North America, chlormequat exhibits concerning toxicological properties, as documented in historical as well as more recently published laboratory animal studies. In the early 1980s, the impacts of chlormequat exposure on reproductive toxicity and fertility were first described by Danish pig farmers who observed reproductive declines in pigs raised on chlormequat treated grains [4]. These observations were later investigated in controlled laboratory experiments on pigs and mice, whereby female pigs fed chlormequat treated grain exhibited disrupted oestrus cycling and difficulty mating compared to animals on a control chlormequat-free diet [4]. Additionally, male mice exposed to chlormequat via diet or drinking water during development exhibited decreased fertilization capacity of sperm in vitro [5]. More recent reproductive toxicity studies on chlormequat show delayed onset of puberty, reduced sperm motility, decreased weights of male reproductive organs, and decreased testosterone levels in rats exposed during sensitive windows of development, including during pregnancy and early life [6,7,8]. Developmental toxicity studies also suggest that chlormequat exposure during pregnancy can dysregulate fetal growth and metabolism [9]. Other investigations did not find impacts of chlormequat on reproduction in female mice, male pigs, or a subsequent investigation of fertilization capacity in male mice developmentally and postnatally exposed to chlormequat [4, 10, 11]. Equivocal evidence in the toxicological literature on chlormequat may be due to differences in doses tested and outcomes measured as well as selection of model organism and the sex of laboratory animals. Consequently, further investigation is warranted."
Thanks for making me aware of this. I've been trying to make a point of avoiding PFAS, but it seems to be everywhere.

Another one is nitrites in processed meat. All the fancy "health conscious" brands proudly state "NO NITRITES!", but then those ass hats put in a bunch of celery salt...which is just nitrites with a different name.
Note: For anyone curious, trader joes actually does sell a bacon with no nitrites of any form. First and only time I have seen it.
Marketing that takes into accounts biases of particular target group. That particular case is, I think, becoming common: since large fraction of the population is irrationally afraid of anything that has numbers in its name, whether as digits or words in any language, the companies look for whatever plant they can pull that specific substance from, and use that in production process - possibly compromising quality and efficiency, but allowing them to write ${good natural plant} in the ingredient list instead of evil E-number or satanic 6-6-hexa-whatever.
I'm conflicted about this practice. On the one hand, I hate pulling wool over other people's eyes; on the other hand, I also hate reflexive fear and anti-intellectualism of our society.
To wit:
People used to do all sorts of self-harming things not knowing any better and now we do fewer of them.
The Romans used to sweeten their wines with powdered lead. The ancient Chinese alchemists used to make elixirs of immortality out of mercury compounds and feed them to their wealthy.
I'm not saying things are good now and that we shouldn't push for them to be better, not by any means.
Rather I am saying that as we take further steps towards optimal human health, aligning our common environmental encounters with our biology, we should remember that the effort people have put in to get us this far is only going to take us half as far the next time, and half again the time after.
And that is all well and good, progress is progress, right?
However, does it not seem like the smaller the flaw we find the more we get upset about it?
I believe this phenomenon is caused by a continuing delusion that we were once ever perfect, that we ever lived in harmony with nature, that there is some paradisian SI Garden of Eden unit we can measure our present environment against, and that the current state of events is the face of our fall from grace and must be destroyed like the monster it is.
I believe the truth is things have never been better in hundreds of ways, and they're going to keep getting better as we repent of our past mistakes and learn more about what mistakes we are still currently making, and that the world 25 years from now will be as different a world as the world of today is to the world of 1999.
That collective handwringing (set in eternal struggle as it is with financial greed) is what got us here, and it's what will get us the next 50% and the 50% after that. Wink and enjoy the ride.
My personal ability to influence these things is so small compared to the vast swathes of the ignorant who just go with the flow of the mainstream.
Any energy I spend trying to influence things outside of my control is wasted.
Therefore, I will only endeavor to control that which I have the ability to control.
"God grant me the serenity", if you will.

Non-reactive also means doesn’t interact chemically with other chemicals, which is a desirable thing in a plastic that might be ingested. While maybe not awesome that it sits in silt not reacting to the end of time, if it also doesn’t react with anything in your body, it’s safe to take into your body, no?
The problem with some PFAS is they don’t readily degrade but they’re biologically reactive and interact with the bodies chemistry. That’s not a great feature. But it’s a huge class of chemicals, all of which are chemicals stable due to their carbon fluorine bonds - one of the most stable bonds in nature. But that doesn’t mean they can’t react in ways that don’t break the molecule apart, or form other chemicals that maintain the integrity of the C-F bond.
But it also doesn’t mean that they DO react.
Life isn’t so simple it can be reduced to a mantra like “plastic bad” or whatever. PTFE has a lot of very useful characteristics, and its lack of reactivity in the body isn’t the least of them.
Whenever this topic of Glide being toxic comes up they cite this article :
https://www.hsph.harvard.edu/news/hsph-in-the-news/dental-fl...
Which is written based off this study:
https://www.nature.com/articles/s41370-018-0109-y
Which is based off blood samples drawn in 2010-2013, which is at the time PFOA was being phased out of the PTFE production process due to lawsuits around the PFOA toxicity, which DuPont was aware of. The new process using GenX (seriously), which is known to cause problems too but at a lesser extreme than PFOA. However the issue with PTFE was with the residuals of PFOA which you don’t find in commercial PTFE for GenX.
And yes, PTFE is widely used in medical implants and devices.

All of those commenters deconstructing my clumsy use of "Noble Savage" (I admit it's not quite the right thing) - are indeed (maybe wilfully) missing the point.
A better expression might be the "Parochialism of the present". But that doesn't quite get to it. Nor even Thomas Hobbes' flowery and overblown conceit of past life as "Nasty, brutish and short".
It's about a phenomenon of lionising a one dimensional idea of "progress" in a patently self-deceiving way.
Noble savage = humans fundamentally corrupted by civilisational progress
Or what other name might we give to this phenomenon of dismissing extinction level mistakes with the appeal to the idea that "hey, it's progress"?
If you don't acknowledge any of the tradeoffs involved in pollution and instead just make a point about harm in a vacuum, it's hard to know how to consider it.
Like the overwhelming exceptionalism of how we all care about the environment and the future health of our children... just don't take our gas-guzzling cars and non-stick pans way!
We are not rational beings, but we so deeply believe we are.
If the cybertruck was out a year earlier, I suspect I know a few people driving "gas guzzling" trucks that would have bought that instead, because it would have been cheaper, faster, and in almost every measurable and unmeasurable quality, better.
Why do you think people will forever hold on to ICE? It strikes me that electric cars are a step change in almost every way, maybe the reason people still have ICE is they didnt have a compatible electric alternative at the time.
Also, as you say, it's an easy way to explain away our problems, to say that people in the past were better and if they were here today then they wouldn't be complaining like we are.
Now, to your contention that "we've screwed up as a civilisation". What do you mean exactly? What civilization and when did the screwing up start?
As I have pointed out in other remarks here today, calmness reasonableness do not make a bad position good. If anything they add a palatable veneer to the harm.
> It in no way overplayed the misery of the past
I completely disagree. The idea that in the past people were "lucky to see their children grow up" is dramatic, and a tautology anyway since we are all "lucky" to see our children grow up in any epoch. It paints a needlessly bleak picture of some awful past that technological progress is implied to have eliminated with justifiable costs.
> What do you mean exactly? What civilization?
Actually, you know what. You're right [0].
"What do I think of Western civilisation? I think it would be a very good idea."

You got me there, I do think the costs for (almost) eliminating famine and diseases with double-digit mortality rates are justifiable. That said you didn't really answer my question, but I'll roll with it.
Consider the extinction of megafauna [0], the deforestation of China [1] or Mesopotamian farming practices [2]. It would be hard to blame these on Western civilization (real or imagined). I'd say we have been operating in the same unsustainable way for a long time. I wish it were otherwise because it would make everything easier.

Fair remark, I brushed it off.
> when did this start?
It started when science and technology changed from something we do, into something we believe in.
I don't think that actually happened any time around the Enlightenment of even the Industrial Revolution, but we're definitely deep in it now. I'll leave you to put the pin in the map.
Also, the cause and effect are not so simple. It's not as if we changed our culture and beliefs, and then embarked on a century of planet-destroying madness. Rather, like the sunk-cost bias of an addict, we realised we are on a bad road, labelled that as "inevitable", surrendered before the forces of "technological determinism" and found we had no choice but to believe.
But that was a false choice.

This question of "facing things" is what bothers me. Sure, science and technology is difficult and has awful side effects. Progress is a complex vector, and it isn't easy to have 'purpose' (telos) see where we should be going.
But what I see here every day is very intelligent, witty, well read people ... using their intelligence against themselves. The extraordinary intellectual acrobatics of denial and apologetics just makes me weep. And so many who just down-vote challenging questions but lack the patience and courage to form an argument.
Fear of the unknown is an impetus for herd mentality.
Hopefully your comment ceases to be gray…
How about adding random characters and line noise to unpopular comments, or replacing odd words to make them seem more deranged and subtract credibility?

Can you hear me?
this is a lame attempt to flatter our intelligence but then criticize for not engaging on what are essentially marketing platforms where the stakes are usually zero, and there is no way to demonstrably prove that we're not shills, morons, or GPT bots.
and IVF works. (yes, it's a bit more risky than the Nike method - just do it, yes, it's expensive, but having kids is a lot more expensive usually.)
the linked BBC article seems to contradict its title ("For the majority of men with fertility problems, the cause remains unexplained")
also, mixing up ability and willingness to have kids is just fucking revolting. of course a lot of people are don't have kids, because bad journalism takes away people's joy. well, also this little thing called ladder pulling, and the usual coordination problems (NIMBYs, etc)
The risk calculation feels different in those cases.
But I agree we live with so many other risks, there may conceivably be better windmills to tilt.
Heart disease dominates the US health problems. Maybe we could do something about food in America. Something we can actually do something about, with a measurable improvement in living.
And so on.
“Sorry kid, but at least your dad got to see you ride your first bike, chalk that up to win, used to be much worse! You know, DuPont and 3M can’t give ground all the time.”
It is very hard to read about the cancer clusters in WV/OH around the heavy PFAS sites and not feel some extreme disgust at how bad it got and feel thankful that this is getting significant attention.
With so many people deciding to go childless i am not so sure.
The new proposed EPA guideline is 4.0[1] parts per trillion (also expressed as ng/L) for PFOA and PFOS.

How does it get into the chickens? No one knows atm. The rain? The food? It seems like the stuff is just everywhere indeed. We also stopped eating our eggs, looking for a testing service.

(I don't remember if that was part of the books too, but in the show The Expanse, a major character who was born and lived on Ceres pondered this occasionally. In the end, he was told by an Earther that "it tastes like nothing, it's just water". I guess this is an improvement over status quo.)
dang? :)

I'd do it myself, but am le tired.
Do we have any sense of the actual amount of PFAS in rainwater, and the human health impact of such? I didn't see any mention of this in the article. Maybe more investigation along these lines would be helpful.
As noted in the article, the EPA recently lowered the "safe limit" based on evidence that the previously acceptable levels were still high enough to reduce vaccine efficacy in children.
And we already know PFAS impact fertility and hormones, can cause some cancers, etc.
Maybe PFAS really are a major problem, I don't know. But I'd love to see a bit more circumspection about this and other issues. Keeping people on red alert, all the time, about everything - does not seem like a recipe for human flourishing overall. Though it may be a good way to keep people under control.
It would help if we had some sort of mechanism to turn these "alerts" into action, which seems to be a sticking point for a globe dominated by society obsessed with corporate liberties to do nothing or double down on the problematic behavior.
The problem is that there's no requirement for demonstration of safety for new products/chemicals, not even monitoring, nothing (in most parts of the world). Which seems obviously bad.
But we currently live in a particularly idiotic mass-communication by memes times, hence we have defund the police and PFAS, and so on.
