Is There an Equine Version of Wind Turbine Syndrome?

While not much gets past WUWT, this story from Portugal has only recently gotten some press, well after its posting in March, and I think it warrants attention here.  While I don’t know much about horses, I’ve known several people who do, so I do know that just because a horse will let you ride it, it may look for a low hanging branch to walk under to scrape you off.

Not surprisingly, I had never heard of “Acquired flexural deformity of the distal interphalangeal joint,” but I came across a web page, Can Wind Turbines Cause Developmental Deformities In Horses? about a stud farm where horses developed downward pointing front hooves after several wind turbines were built nearby.

If I were a horse, I would not want my feet to look like the one on the right:

Image

Left foot is normal, right foot has an acquired (post birth) flexural deformity.

No other changes in rearing the Lusitano horses (a famous Portuguese horse breed that I never heard of) were known.  In the ensuing investigation, “two of the affected foals were placed in a pasture away from the initial one and two others were admitted at the Faculty of Veterinary Medicine of Lisbon. In those animals, except for one that had to be euthanized for humane reasons, an improvement was observed on their condition, with partial recovery of the deformity.”

The stud farm was studied as part of a masters thesis by Teresa Margarida Pereira Costa e Curto and it surmised:

Cellular Mechanotransduction is the mechanism by which cells convert mechanical signals into biochemical responses. Based on the mechanical effects on cells it was proposed in this research project that the ground vibrations were responsible for a increased bone growth which was not accompanied by the muscle-tendon unit growth leading to the development of these flexural deformities.

That sounds reasonable to me, I know that stressing human bones increases their calcium uptake, and I wouldn’t be surprised that something like that could affect feet in other animals.

The wind turbines are obvious prime suspect, they were built nearby:

Turbine proximity to farm

So, WUWT readers who actually know something about horses, have you heard of this case or similar cases at other farms with new wind turbines? Or, if you live near wind farms that are near farms with horses, cattle, etc, have they had problems like this?

This is just one study, involving one farm and not very many horses, clearly more research is warranted.  If it’s confirmed, it would be interesting to know if other animals are susceptible to a similar problem.

If I wasn’t a horse I wouldn’t want my leg to look like either of the pictures.
But I am sure that this disease has to be caused by global warming, because there is nothing that isn’t caused by global warming.

Gene Selkov

No way! I don’t know a lot enough about horses, but it is a common enough condition that occurs with or without wind farms in sight.
At any rate, I’ll bet vibrations originating on the farm will be orders of magnitude higher than anything from a wind turbine. Not that I believe vibrations can have anything to do with it.

SteveC

My horse is fine… course there are no wind turbines in sight! So that proves those windbeaters are to blame!

TimTheToolMan

Ric writes “That sounds reasonable to me”
Really? How much ground vibration is there at that distance? It would be an easy one to test anyway.
[The article includes a graph of ground acceleration and has peaks, if I can make out the numbers, and if the scale is accurate, of 0.04 cm/sec^2. “g” is 980 cm/sec^2, a big ratio of course. However, I have no idea what that feels like.
Ah, ftp://ftp.ecn.purdue.edu/ayhan/Aditya/Papers/Wald%20Quitoriano%20Heaton%20Kanamori_1999.pdf suggests the threshold for sensing vibrations is 1-2 cm/sec^2, so they’re measuring something at least 1/25 to 1/50 of what people can sense. Certainly makes it seem unlikely the cause.]

Henry Clark

To noticeably and quantitatively substantially shake the ground over many acres like a continuous earthquake would take capabilities beyond those of anything built by modern industry. For instance, a nuclear bomb briefly disturbs the ground somewhat out to kilometers of radius, but it doesn’t do so continuously. The power requirements would be immense if you trying to do so, fantasy supervillian style.
I can’t believe wind turbines do so.
I assume this article is well intentioned, but I must be blunt:
It unfortunately has the same fallacy of many environmental myths: quantitative, mathematical illiteracy.
Such is taking a qualitative truth and misapplying it. For instance, that a ball is shaken if it is impacted is true in itself, but someone could not properly conclude that, therefore, if he jumped up and down, he would knock the giant sphere of the planet Earth out of orbit.
Is it true in itself that bones are affected by stress? Certainly. Grow chickens in a multi-g centrifuge, for instance, and the result is much different from 1g chickens. (In fact, the harm to bones from continuous zero-g exposure for current astronauts is much like the harm in event of months of totally continuous bedrest, probably solvable by the same means of even a fraction of a hour a day walking around in 1g gravity or pseudogravity, though present spacecraft have too low mass budgets, a separate topic).
But wind turbines don’t change stress on bones in surrounding kilometers to a quantitatively sufficient degree for this article’s implication.
I’m not a fan of wind turbines in particular. But, if arguing against them, let’s rather use the many valid points which can be made.

I don’t know about the case you mention above, but the illness has been common. At least that is how it appears by this article.

I live surrounded by the world’s largest wind farm & lesser infestations thereof, & amidst thousands of horses without having heard of the association of this deformity with the hideous uneconomical bird & bat massacring monstrosities. My sister in law is a large animal vet, so I might have were it a problem.

And even the bird & bat masscre is I think being exaggerated. Hit them for what they actually do: they hurt our wallets and support fraud.

Good link. That shows non-absurd causes. For instance:
Congenital flexural deformities are present at birth
Proposed aetiologies [causes] of congenital flexural deformities include malpositioning of the fetus in utero, nutritional mismanagement of the mare during gestation, teratogens in various forages ingested by the mare and maternal exposure to influenza virus, or the deformities could be genetic in origin (Kidd and Barr 2002; Hunt 2011).
Acquired flexural deformities generally develop when the foal is aged 2-6 months and generally involves the DIPJ initially. The aetiology of this deformity is unknown, but speculated causes include genetic predisposition, improper nutrition (i.e. overfeeding, excessive carbohydrate [energy] intake, unbalanced minerals in the diet) and excessive exercise.”
“It is the current author’s opinion that a large contributing factor to this syndrome is contraction of the muscular portion of the musculotendinous unit caused by a response to pain, the source of which could be physeal dysplasia or trauma from foals exercising on hard ground. […]
Any discomfort or pain in the foot or lower portion of the limb coupled with reduced weightbearing on the affected limb appears to initiate the flexor withdrawal reflex, which seems to cause the flexor muscles proximal to the tendon to contract, leading to an altered position of the DIPJ. This shortening of the musculotendinous unit shifts weightbearing to the dorsal half of the foot causing a decrease in sole depth and bruising of the sole, reduced growth of the dorsal aspect of the hoof wall, and excessive hoof wall growth at the heel to compensate for the shortening of the musculotendinous unit.”
“A genetic component must also be considered for acquired flexure deformities, as some mares consistently produce foals that develop a flexural deformity in the same limb as the dam or grand dam in which a similar deformity is present. The genetic component of the flexural deformity may be the ultimate determinant of the severity of the deformity.”

“a horse will let you ride it, it may look for a low hanging branch to walk under to scrape you off.”
And I don’t blame it.

Richard Sharpe

Looks like Equine Excreta to me.

Severian

Lets see, one study…gee, add a computer model and you’ve got the basis for an entire consensus proven theory!
It will be ignored even if true. It is demonstrably true wind farms kill bats and birds by the thousands, including endangered raptors, but the greenies ignore that while obsessing over six or seven birds killed accidentally at a refinery when they got thru the netting and into an oil pond. Gotta have your priorities straight you know.

Wesley Schnelle

I’m not quite sure how a question can be considered as fallacious.

Janice Moore

Dear Ric,
Your heart was in the right place and it took your mind in the right direction (which is why the hardened hearts at IPCC end up in such ludicrous positions). I think, however, that the trail petered out into implausibility, once we all went down it a ways. I did a little bit of research on Bing and I think a more likely explanation for the “injury” might be found in the area of tourism. If that horse rancher uses the horses for tourists to ride on trails which have been ruined by the hideous sight and sound of windmills, that rancher might want to find a way to get rid of the windmills.
Sigh. I wish, in a way, that the horse injury story was true, then we might get rid of blight and an investment scam at the same time. What’s a few thousand dead birds and bats, but, a HORSE… . Nope, it wouldn’t work. Not dead. They can move. It is the rancher who would suffer (move or get rid of my horses). And he or she is just a person. What are people? Per David Suzuki and his ilk, they are just “maggots.”
Sad, isn’t it? The daily slaughter of birds and bats should be enough for the so-called environmentalists who are so enamored of windmills (because it feels good to them) to call for their perpetually economically inefficient operation to be STOPPED. Such kindhearted, caring, people — NOT.
Thanks for bringing this to our attention, Ric. It was worth a try.
With gratitude for all the fine posting you do on WUWT (and for your Guide),
Janice

There’s so much bogus weirdness blamed on “global warming” that it’s kinda nice to see some of the bogus weirdness blamed on the “green energy” people for a change.

Would it have to be vibration of the ground? Why not of air? Could stress cause such a problem? Those windmills put out sound that greatly disturbs people living nearby, and upsets livestock too. It might be easy to dismiss such the possibility raised in this article by assuming the vibration has to be ground vibration and “impossible”, but let’s not be so quick to rule the turbines out.
If the horses written about didn’t suffer such problem until after the turbines went up, then there might be something to the theory, no matter how much people don’t want there to be.
Aerial photos of other horse farms with similar problems would be useful here. It would also be interesting to see the aerial photos of those who claim to live near wind farms with horses that don’t suffer from such problems, to see just how close they actually are.
I could claim to live near a wind farm, for instance, but in actual fact it’s some miles down the road.
If I was living in a paddock and something new and strange loomed up on the hills making strange noises day and night, and I didn’t know what it was, I might end up a nervous wreck, too.

Janice Moore

Sorry, mods, I don’t know what I said… (“in mo-d-eration” at 9:37pm).
P.S. Ric, if that rancher is intentionally injuring his or her horses to try to get rid of the windmills, then, that rancher should have all his or her horses immediately confiscated and never allowed to own a horse again! Just had to say this so you would know, given what I wrote at 9:37pm, that I would not approve of such a terrible thing, even if it DID get rid of all the windmills.

I thought this was going to be something to do with replacing wind-powered subsidy harvesters with horse-powered windlasses.
Leads me to a completely OT question: There’s an old mining engineering textbook, written by a Scotsman (why are we not surprised) maybe 200 years ago? Can’t remember the author’s name, but it was revised and reprinted numerous times. I know an opal prospector who has a copy that could be 100 years old. (He looks a little younger, but not much.) Loads of notes in the margins, but otherwise carefully preserved. The guy still uses it, just converts the “horse” bit to some other motive power such as a diesel stationary engine or electric winch. Claims it provides solutions to problems that are “too difficult” today.

johanna

Horses are wild animals, and the smaller ones like Shetland ponies are the least tractable. Racehorses are notoriously scatty, and nobody who works with them for long avoids getting kicked or bitten.
OTOH, very large, heavy breeds can have stable and intelligent temperaments. The novel “My Friends, the Miss Boyds”, by Jane Duncan, about growing up in a community that relied on horses, is instructive. Set in Scotland in the early part of the C20th, the importance of having good horses is unmistakeable. And, that included treating them as individuals, because they were not like the cows that obediently turned up for milking every night.
It’s interesting – dogs just couldn’t wait to be domesticated, but horses only hang around humans because they have to.

Horses probably have a IPCC like sensitivity to dead bats.

TimTheToolMan

Ric writes “so they’re measuring something at least 1/25 to 1/50 of what people can sense. Certainly makes it seem unlikely the cause.”
I would think a paddock next to a reasonably busy road with heavy trucks would produce larger peaks albeit much less regularly. I suspect they could be barking up the wrong pole.

Steve W.

I can think of a few reasons why this cannot be:
1. Horses POUND on their hooves just trotting around. This has to be thousands of times stronger vibration than turbines produce, just living their normal lives.
2. Our horses were often driven around in horse trailers, sometimes for hours. There is huge vibration then. No problems.
Do I really need to remind you that correlation does not imply causation?
This really feels like quackery. I know y’all don’t like turbines, but I really feel sick to my stomach seeing something this poor on wattsupwiththat. Do you really want people to laugh at you?

davidmhoffer

TimTheToolMan;
I would think a paddock next to a reasonably busy road with heavy truck
>>>>>>>>>>
Or a railway line. Or a cargo shipyard. Or a strip mining operation. Or a large waterfall. Lotsa stuff induces vibrations into the ground, one would think that there would be deformed horses all over the planet if such a report were true.

Stop thinking only ground vibration, people, there’s more to wind turbines than that and plenty of health/stress problems associated with them. I thought the whole point of any scientific investigation is to look at all aspects and not dismiss something out of hand based on one aspect alone.
It’s great that ground vibration can be thrown out, or seems unlikely. It’s a fair point. What about the rest of it? Putting blinkers on and dismissing a claim as preposterous without even bothering to consider it is what the other side does. Can we at least have a scientific open mind?

Jquip

Dunno. Plausible from a long distance if you squint just right. But for now I’m calling this one a Texas Sharpshooter.

tobias

I have to add and it may (will) be very politically incorrect and revolting for some people, but not too long ago when the economy was flying high in many countries owning horses was a status symbol. When those economy cratered, horses became a liability for, not only the owners, but for all of those countries economies (the farmers, for hay lost, stable crews lost jobs, veterinarians, transport companies, race tracks the dominoes just kept on falling). The owners fled their responsibilities and in many cases left the horses.
There are some gruesome stories associated with this and may have led to some of the “tainted meat” scandals in the past few years.
And I know I am going to offend A LOT of people here but after WWII ( not the only situation), when all food was scarce, just about “anything ” to survive was done. My parents and many others used horse flesh to survive and I am sure in some areas many still do.
And tell me why not??
Are these people just looking for a way out of a serious personal economic problem and using excuses? Or do we need to change a way of thinking?
REMEMBER we eat::
Steer, cow, veal,, sheep, lamb, deer, moose, caribou, reindeer, bear, grouse, elk, fish, shark fins,( just one piece of an animal and the rest thrown out as happens with other species), urchin, oysters, clams, whales, dolphins, chickens, turkeys, pigs and piglets , birds, squirrels, beavers and in some areas, monkeys, elephants, giraffes, dogs, cats, mice, rats etc. etc.are all consumed by humans .( I forgot worms, grubs caterpillars, spiders etc, etc.) If the horse population for what ever reason becomes an issue we need to look at options.
I truly apologize to anyone upset by my comments.
But just looking at some of the totally illogical thinking on this planet at times, it kind of just came stumbling out, Tobias Smit.

Greg Goodman

Study group of four. Three got better except for the one that died.
Apply a little selection bias and eliminate the ‘outlier’ as ‘unsuitable for the study’ and we have 100% of the study subjects showed signs of recovery when they were removed from the area affected by wind turbines.
Control group size = errm, zero.
Ric this is HORSE SHIT.
If you can not smell that a mile away may I recommend a nasal decongestant.
Please send Dr. Chapman a note about that too.
[One of the reasons I posted this was to give it a good airing. Besides, Anthony has posted worse recently. I suspect many commenters haven’t bothered to follow the link to the full story, you included. That refers to eleven horses, unfortunately it doesn’t mention the total number, presumably the full paper does, but it’s in Portuguese.
Another reason to post this was to see if the WUWT community knows of similar situations elsewhere. If there are, that would be interesting. So far, just a useful negative suggestion from milodonharlani.
While there certainly needs to be a control group, but for a preliminary study, I deemed it interesting enough to post here.
Suppose you owned a small horse farm and several horses started developing deformities. Presumably you’d talk to your vet, let’s say he could find a reason worth recording. Then what would you do? Commission a study with dozens of farms with and without wind farms, cart horses between farms and look for impacts to extremities and internal organs? Experiment with different feeds in case the feed companies hadn’t done adequate development work on that? In this case, it appears the farm’s owners asked the local Ag school to take a look and see if they could identify the problem. -Ric]
[Oh yeah, I suggest you not take a look at Chapman’s site. :-)]

Adam

Those wind turbines are very far away from the stables to be able to produce a vibration which could hurt a horse foot. Besides, it is a not really a relevant story for this site.

Greg

It must be obvious to anyone with any objectivity that the cause of this affliction in portugese horses is the dramatic increase in atmospheric CO2.
How blind can you all be?

I find it hard to believe like most of you that the turbines could be causing this. But that being said a Lusitano is a huge horse, often 6′ at the shoulder when full grown.(Think the horse from The Black Stallion, that was a Lusitano) These were foals, which means they were under a year in age. Big horses like the Lusitano ,especially purebreds do not fully develop their bones, muscles and tendons, etc. until they are about 3 years old. These are very expensive horses, the stud farm owner is not going to willingly do anything that will damage their legs. Nor is he worried about getting $20 an hour to take tourists on a horseback ride. These horses do Dressage and Grand Prix jumping, not trail rides.
It is really odd that they would have 4 foals all at the same time develop this infirmity.

Things that are wrong with wind turbines.
1) They are uneconomic
2) Variable in their power production.
Fantasises about wind turbines.
1) They are major Bird and bat choppers, as a cause of bird and bat mortality they come way down the list. If you really worry about birds try campaigning about cars and cats, Hunters and a host of other things before you get to wind turbines.
2) They are damaging to horses hooves, yeah right. Constant vibration? I thought they were not working most of the time.
3) They are dangerous for Father Christmas on his rounds, well, that’s as likely.Hopefully you get my drift.
I know many people hate wind turbines, but be reasonable in your rationales otherwise you end up as a laughing stock when you site horses hooves and bird choppers.

kadaka (KD Knoebel)

Wow, amazing. It’s been discussed here before, in comments etc, how animals are “alerted” before earthquakes. Low frequency waves transmitted through the ground are suspected.
It’s also been learned how animals like elephants communicate with low frequency sound, which travels farther than high frequency, at frequencies below human hearing.
http://swa.com/members/publications/garstang%20jcp.pdf
Yet the possibility of the turbines generating low-frequency sounds, that can be transmitted through air and/or ground, that the animals are sensing and it’s causing them health problems, with many of them often attributed to stress when humans get them,
Is casually dismissed out-of-hand, can’t possibly be true.
Is what’s really going on, is certain individuals prefer to ignore this possibly Inconvenient Truth?

DanJ

“Is there an equine version of wind turbine syndrome?” There is indeed; both ideas are made up and not supported by any real research.

Gareth Phillips

Seeing there is general agreement that the horse hoof / wind turbine study is complete tosh, I thought it may be useful to also put the bird chopper idea into perspective with some mortality figures. It may upset the alarmists, but it’s useful info.

I think this is a windup to get ‘deniers’ excited and then warmists can chortle over it.

Berényi Péter

It may not be the ground which is shaken, but the horse. Has much smaller mass with large cavities in its body, therefore a good receiver of low frequency aerial vibrations. Even then, if there is a connection, I would suspect the vestibular system to be affected, not the entire body. If anything is wrong with the sense of balance, that can bring about persistent behavioral changes, which in their turn may be responsible for developing bone deformities.
Anyway, wind turbines are unbelievably noisy at frequencies below 0.1 Hz. These vibrations are inaudible, nonetheless have a huge effect on the workings of the inner ear, including the vestibular system. Low frequency vibrations can also travel large distances unattenuated in the atmosphere, circumvent obstacles and penetrate buildings freely.
The biggest problem is we do not have regulations whatsoever for low frequencies. Standard noise control equipment is not even suitable to measure them (low frequency infrasound is not picked up by microphones), one needs a microbarometer to do that, which authorities do not have.
We clearly need regulations on industrial environmental infrasound emissions along the entire frequency range, extending well below the threshold of hearing, down to 0.01 Hz, which is not even considered “sound” by some. There is a wealth of literature on the detrimental effect of high infrasound levels on the cochlea and the vestibular system, but they are regularly dismissed by wind farm companies on the basis that these emissions are not against the law. Which is, unfortunately, true.

Scarface

Cows would have the same symptoms and I never heard anything like this around here. And believe me, there are a lot of cows and a lot of windmills overhere. But, time will tell.

Kev-in-Uk

I’d say this was highly suspicious as a confirmed link, certainly from the ‘evidence’ presented! However, it must be said that turbines do produce both noise and vibration, possibly even very low frequency rumbles and ultrasonic type vibes (think of the air vortices at the tips of fast moving blades)?
I would doubt these can have a direct physical effect on animals, but if anyone has been and sat next to a turbine for a while, the thwop thwop thwop can be somewhat disturbing. Without trying to be too dismissive or ultraserious, if I were a standing hooved animal getting disturbed by this type of thing, I might be lifting or pawing my feet more than usual? (Think of the equivalent of white finger syndrome in humans).
[Ultrasonic sounds are likely way down on the list, as they dissipate fairly quickly, even in the distance suggested in the aerial photo. I was a little surprised that they seemed to lean toward ground vibrations, since that’s one possibility for what four footed animals may sense for earthquake precursors, what the heck. At least it was a change of pace from the common references to infrasonic sound. -Ric]

Joe

I’m not quite sure why people are so quick to pull a warmist on this and deride it without consideration. For the record, my gut feeling is that it’s extremely unlikely that the turbines have anything to do with this, especially given the many more plausible possibilities.
Not least, the fact that there’s a previously suspected genetic component and this is a stud farm, which is in the business of manipulating genetic traits – including, at times, the unwitting “selection” of undesirable ones.
However, most of the arguments put forward above as “proof” that the story is horse manure are no better than the warmist claim that “natural variation can’t explain the warming”. Just because one aspect (ground vibration) appears to be too weak to have an effect doesn’t mean that other aspects can’t be involved.
Even the apparently weak ground vibrations could turn out to have an effect far out of proportion to their magnitude – you can go to the gym and repeatedly hit a punch-bag without damaging your wrists, or you can type gently at a PC keyboard and develop RSI.
I say again so there’s no misunderstanding, I suspect that the bat-killers aren’t to blame here, but if we want to champion open-minded science then we should champion all open minded scientific enquiry, including that which we suspect is flawed or which challenges our preconceptions.
That doesn’t mean we need to spend much time on it, but we should respect those who choose to (the authors of this study, for example) and we should be willing to consider their results impartially and see if they’re borne out by further investigation.

From just a few days ago, 9/22/2013, from Forbes by James Conca, Contributor (bold beyond title added):

Wind Energy Gets Away With Murder

I guess it’s the hypocrisy that galls. Under both the Bald and Gold Eagle Protection Acts and the Migratory Bird Treaty Act, the death of a single eagle is a felony, and the Administration has prosecuted oil companies when birds drown in their oily facilities, and fined utilities when birds are electrocuted by their power lines.

According to an estimate published in the Wildlife Society Bulletin in March almost 600,000 birds are killed by wind farms in America each year, including over 80,000 raptors such as hawks and falcons and eagles (Wildlife Society). Even more bats die as their lungs are inverted by the negative pressures generated behind the 170 mile-per-hour spinning blades.

On the other hand, the White House is considering giving wind generators permission to kill a set number of eagles for the next 30 years, at the urging of wind-energy lobbyists. Unfortunately for eagles, such permission is not subject to an environmental review because it is only an administrative change.

The Interior Department repeatedly overrules its experts at the Fish and Wildlife Service on the wind issue. The wind industry actually became part of the committee that drafted and edited the guidelines and pretty much got everything it wanted, including stripping law-enforcement agents in the field from having the authority to file charges with federal attorneys.
Wow! Just like Big Oil. I guess Wind has really arrived.

Gareth Phillips, that Wildlife Society Bulletin mentioned is linked at the organization’s name. Please review so you can report more accurate numbers next time. 😉

Thank you Gareth. So to all those who have suddenly and conveniently become bird preservation advocates and unbearably concerned with the longevity of bats:
please cover all your windows with sticky tape and stop driving , or shut the hell up about “bird-choppers”.

Would one horse suffering from the same simptoms and not raised in the presence of wind generators falsify the theory?
When one of my apprentices was confronted with the AGW theory, his first question was: Has it ever been this warm before?
When it is not a pure lab situation, the right question can save a lot of money 🙂

Jquip

negrum — “Would one horse suffering from the same simptoms and not raised in the presence of wind generators falsify the theory?”
In fairness to the authors, or not, this is a grant funding request more than a study. They found a plausible, to them, mechanism for causality and a statistical whoopsie. They have done no more than note this and state that future work would be needed to put it one way or the other. But it is a statistical model. Given known rates of the condition in question, it’s a matter now of collecting enough samples near turbines to see if there’s any statistically significant difference. Establishing causality through lab replication of the conditions is also possible, natch. Just not the typical approach for such things.
Way too much epistemic ignorance at this point for anything more than a “Huh, weird.” No harm in chasing it if you have the money. No harm in waiting for someone else to chase it.

kadaka (KD Knoebel)

From CFACT, March 18, 2013 by Jim Wiegand:

Wind turbines kill up to 39 million birds a year!
Big Wind hides evidence of turbine bird kills – and gets rewarded. Here’s how they do it.

Whoa. They really did rig the game in their favor, to keep the “wind power” sympathizers and sycophants in the dark, or to at least shield them with plausible deniability.
If these people are willing to slaughter millions of critters every year and cover it up, all for the sake of money, how could we ever trust them to not get rid of a few inconvenient humans and cover it up?
