Zika Virus Does Not Cause Birth Defects - Fighting It Probably Does

The media said that the mosquito borne Zika virus is likely causing microcephaly as well as dozens of other illnesses. They also claimed that insecticides were not related to the development disorder. They seem to have been wrong on both cases.

Since December 2015 U.S. media ran a panic campaign round the Zika virus. That virus was said to cause many bad things including microcephaly, a development distortion of the head  of unborn babies, if the mother was infected with Zika during pregnancy.

After looking into the issue and the available data I concluded that: The Zika Virus Is Harmless:

The virus is long known, harmless and the main current scare, that the virus damages unborn children, is based on uncorroborated and likely false information.
There is absolutely no sane reason for the scary headlines and the panic they cause.

The virus is harmless. It is possible, but seems for now very unlikely, that it affects some unborn children. There is absolutely no reason to be concerned about it.

As this is all well known or easy to find out why do the media create this sensation?

By March the media attributed all known human ills to Zika though every headline doing so included a telltale caveat may. I mocked these in Reading About Zika May Hurt Your Brain

[E]ven while Zika is known to be less harmful than an average flue, one headline after the other tries to create the impression that it is some really awful, new bug that may be responsible for about any ailment. That it may spread like wildfire and may have other terrible consequences. May, as in 'the sky may fall', is indeed the most operative word here.

There followed a collection of 35 recent "Zika may cause ..." headlines.

Meanwhile doctors in the Zika affected areas in Brazil pointed out that the real cause of somewhat increased microcephaly in the region was probably the insecticide pyriproxyfen, used to kill mosquito larvae in drinking water:

The Brazilian doctors noted that the areas of northeast Brazil that had witnessed the greatest number of microcephaly cases match with areas where pyriproxyfen is added to drinking water in an effort to combat Zika-carrying mosquitoes. Pyriproxyfen is reported to cause malformations in mosquito larvae, and has been added to drinking water in the region for the past 18 months.

Pyriproxyfen is produced by a Sumitomo Chemical - an important Japanese poison giant. It was therefore unsurprising that the New York Times and others called the doctors report a "conspiracy theory" and trotted out some "experts" to debunk it.

But facts are facts and as these come to the fore the embarrassed media will now likely stay silent.

The New England Complex Systems Institute in Cambridge just published a new study that falsifies the assumed link between Zika and microcephaly. Science Daily reports:

In Brazil, the microcephaly rate soared with more than 1,500 confirmed cases. But in Colombia, a recent study of nearly 12,000 pregnant women infected with Zika found zero microcephaly cases. If Zika is to blame for microcephaly, where are the missing cases? Perhaps there is another reason for the epidemic in Brazil.


Well, maybe those doctors on the ground in Brazil knew what they were talking about. The scientist at the New England Complex Systems Institute also researched the pyriproxyfen thesis. They found:

Pyriproxifen is an analog of juvenile hormone, which corresponds in mammals to regulatory molecules including retinoic acid, a vitamin A metabolite, with which it has cross-reactivity and whose application during development causes microcephaly.
[T]ests of pyriproxyfen by the manufacturer, Sumitomo, widely quoted as giving no evidence for developmental toxicity, actually found some evidence for such an effect, including low brain mass and arhinencephaly—incomplete formation of the anterior cerebral hemispheres—in rat pups. Finally, the pyriproxyfen use in Brazil is unprecedented—it has never before been applied to a water supply on such a scale.
Given this combination of information we strongly recommend that the use of pyriproxyfen in Brazil be suspended pending further investigation.

Sumitomo sold a poison in Brazil which was supposed to prevent the spread of mosquito borne Zika virus by hindering the development of mosquito larvae. Suddenly cases of the human development disorder microcephaly occurred. The company knew that their insecticide could cause birth defects in mammals. But they continued to blame the Zika virus which then increased demand for their poison to "prevent" the further spread of that false Zika cause.

Some enterprising lawyers might find enough material in this case to hold the company responsible for the suffering it probably caused for many families in Brazil.

But the media should also be held responsible. First for spreading a false panic and for attributing all kinds of nonsense to a harmless flue virus. They should also be held responsible for not diligently investigating the possibly human-effected cause of the development disorder. The one that now seems to turn out to be the real culprit.

Pyriproxyfen is produced by a daughter company of U.S. mega poison dealer Monsanto

That product is produced (Wikipedia) by Sumitomo Chemical which is unrelated to Monsanto. They may have cross-licensing agreements and the like, and they are probably good friends, but Sumitomo is independent and is a very big boy on its own. They are both in the poisoning business that is sure.

More than that, for complicity in covering up ... 'conspiracy theory' ... I found several reports, one from Australian experts comes to mind ... at the time, 'debunking' the Pyriproxifen link. Never believe anything until it's been officially denied. That's no longer a joke, it's a truism, given the amalgamated Medical-Industrial-Press-Government combine.

Thanks for unblocking me.

Wow, a very interesting article and one easier to follow and understand than some other article I have read about a possible connection among the release of GM mosquitoes in NE Brazil, the overuse of pesticides and the frequency of microcephaly among babies in that region. It's one of the poorest regions in Brazil as well so malnutrition in pregnant women and how that interacts with long-term pyriproxifen exposure should not be discounted.

Thanks B for all the work you've done and for this excellent blog.

The Media belongs to six corporations which post multi-billion dollar annual sales figures. Media consolidation was enabled by the repeal of antitrust (anti-monopoly) laws via baaksheeshed executive, legislative and judicial branches of government thru Congress and the complicit FCC. The FCC is staffed by corrupt politicians in a revolving door mechanism between it, Congress and other government bodies.

The Center For Disease Control is likewise corrupted and expropriated. It creates health scares and false pandemics as ordered.

These systems function together to protect each other and other billion dollar corporate interests at the expense of the best interests of the public.

The Zika Virus is one of a number of false pandemics.

We can see clearly how important it was to create a false Zika pandemic in order to protect powerful interests like Monsanto which poison - at will - our land, food, water, air and other resources.

I second that. Don't take this as Gospel, but I've found it helpful, when being blinded with science/ gobbledegook, to recall that Most if not All experts in their field can translate their technical knowledge into plain language. So any "expert" who can't do that is probably NOT an expert (except, perhaps, the String Theory crowd who seem happy to admit that they don't understand S/T very well, either).

The CDC released a news item on April 13 of this year headlined, "CDC Concludes Zika Causes Microcephaly and Other Birth Defects." The body of the piece then proceeded to say that the headline was actually false, saying that, "The report notes that no single piece of evidence provides conclusive proof that Zika virus infection is a cause of microcephaly and other fetal brain defects," and that the conclusion is based on studies of the "correlation is causation" nature.

The great National Health Service men and women who defeated Malaria in the American South are spinning in their graves.

b you have very good instincts. I dismissed your warnings last December because you claimed then that there was no evidence for the increase in the the number of microcephaly cases in Brazil. That was incorrect as you seem to accept now. The question then was what was the cause of the increase. I read the reports available then and could see fairly quickly that, at that time, there was no epidemiological evidence supporting zika virus as the cause. It was also clear that the proper serological tests were already being conducted with the mothers of the affected infants. Of thousands of cases, there were just a few dozen mothers who had sero-converted to zika antigens and only two infants that proved positive for the zika particle. Basically, that means there was zero evidence that zika caused the condition.

I don't blame the press for this fiasco. The main culprit, IMO, was the director of the Center of Disease Control when he basically acknowledged that the proper epidemiological studies had not been completed but then said, based on preliminary data, that he believed zika would be implicated. The CDC has over many years gained a well earned reputation for reliable reporting. The press jumped on this together with some anecdotal stories out of Brazil and just ran with it. As of today I haven't seen any reports on the full study but know it is going on because some of the labs have been releasing the results of individual tests (that is how the dozen or so positive sero-conversion and 1 or is it 2 positive particle tests showed up in the news).

In any case, b, you definitely smelled the BS in this story early on.

No, that wasn't incorrect. There were at that time no data available that allowed for a hard conclusion that the numbers of cases had actually risen. The Brazilians themselves said then that they did not know if the comparison numbers of earlier years were well founded enough to allow for conclusions. Diagnostic criteria had varied, data was incomplete, personal wasn't trained to take sound measures. They seem to have cleaned up their data by now and finally confirmed statistically significant clusters. At that time the reporting did not show any "evidence" that allowed for any hard conclusion.

The slavery of the media - from the corporate ownership detailed by ff @6 - is becoming a worse problem as the position of the US worsens, and the media have no brief to report it. I'm thinking principally about the absence of Mutual Assured Destruction in western political culture, and the Russian dilemma now of how to forestall global escalation when the populations of the west are simply unaware of the brinkmanship going on.

But I can see now that domestic US crises could easily arise that start killing people - epidemics or disasters of some kind - and the population might rudely be woken to the fact that their media has no clue how to report reality. Very similar to the blindness coming from the White House that was suddenly made visible as Katrina was unfolding in New Orleans.

This kind of wake-up would be a good outcome, if it played this way. It would be useful to find out just how many people in the US are plugged into alternative news sources outside of the 6 corporations.

Just some speculative thoughts.

I agree b. I myself wrote about the pyriproxyfen link some months ago in various commentaries. But; I've heard different statements about microcephaly cases outside Brasil.It's absolutely crucial to make sure the case ratio in other Zika-affected areas. Not being a scientist this is the only way to probably debunk the Zika is the culprit-theory. Currently it is firmly installed almost in every media outlet. That's annoying. I have no real explanation for this behavior though.

b @18 said: No, that wasn't incorrect. There were at that time no data available that allowed for a hard conclusion that the numbers of cases had actually risen.

True but there were physicians on the ground that noted an increase. Their stories have since been confirmed. I remember the early reports warning about the emergence of AIDS. It was just a scattering of clinical reports indicating that a new disease had just appeared. No one would would say that available data "allowed for a hard conclusion" but it took only about 6 months to confirm those early reports. Clinicians on the ground are the first to notice the appearance of new syndromes. It takes awhile to come up with the hard data.

So maybe the hard data that the number of cases had actually risen was not yet in last December, in fact, we have to agree that the number of cases have actually risen.

Man, another great conspiracy theory on ZV – last time it was the vaccine mfg’s, now it’s the larvacide mfg’s. You ain’t gonna’ let go of this ZV thing, eh? As noted by a couple of comments above, last time, Feb05|16, you tried to convince us that the whole microcephaly thing was bunk because the data were “false.”

Synopsis: We do not know if the virus harms unborn children children [sic] at all. But that number of 4,000 cases looks suspiciously high. That is because it is false.

I dissected your numerical analysis at comments #51 and #52 of that thread. Apparently you now agree that there is a microcephaly problem. You are now saying microcephaly really is a problem and is caused by the larvacide pyriproxifen.

Recall that back then you wanted to go vaxxer on us and blame the vaccine companies:

Cui bono? Has someone a vaccine they want to sell? Is this to damage Brazil's Olympics?

Nothing you now say about the larvacide conspiracy is new or original, it can all be found on Wikipedia, including evidence that this conspiracy theory doesn’t fly.

Some clips from Wiki on the pyriproxyfen theory:

On February 3, the rumor that pyriproxyfen, not the Zika virus, is the cause of the 2015-2016 microcephaly outbreak in Brazil was raised in a report of the Argentinean organization Physicians in the Crop-Sprayed Villages (PCST).[17] It attracted wide media coverage.[18][19] The statement from Abrasco was cited in the PCST report; subsequently, Abrasco clarified that position as an misinterpretation of their statement, saying "at no time did we state that pesticides, insecticides, or other chemicals are responsible for the increasing number of microcephaly cases in Brazil."

On February 13, the Brazilian state of Rio Grande do Sul suspended pyriproxyfen's use, citing both Abrasco and PCST positions.[22][23] The Health Minister of Brazil, Marcelo Castro, criticized this step, noting that the claim is "a rumor lacking logic and sense. It has no basis." They also noted that the insecticide is approved by the National Sanitary Monitoring Agency and "all regulatory agencies in the whole world". The manufacturer of the insecticide,

George Dimech, the director of Disease Control and Diseases of the Health Department of Pernambuco in Brazil, gave an interview to the BBC where he pointed out that the city of Recife has the current highest reported amount of cases of microcephaly, yet pyriproxyfen is not used in the region, but another insecticide altogether.

Neurologist Vanessa van der Linden stated in an interview, "Clinically, the changes we see in the scans of babies suggest that the injuries were caused by congenital infection and not by larvicide, drug or vaccine."

Noted skeptic David Gorski called the claim a conspiracy theory and pointed out that antivaccine proponents had also claimed that the Tdap vaccine was the cause of the microcephaly outbreak, due to its introduction in 2014, along with adding, "One can’t help but wonder what else the Brazilian Ministry of Health did in 2014 that cranks can blame microcephaly on."

Your biggest problem is that pryiproxifen has been used all over the world for decades, so why is it now causing microcephaly as you claim?

You link to a Science Daily report that purports to summarize a report from “New England Complex Systems Institute” that purports to discuss a ZV study out of Columbia published in the New England Journal of Medicine. The NEJM study found that in almost 12,000 pregnant women followed in Columbia who had been exposed to ZV during pregnancy, not a single birth or fetus was found with microcephaly.

Wow!! Do you realize what a stunning finding that is? When you realize that just the baseline rate of microcephaly in Columbia is 2 per 10,000, what this appears to say is that, not only does ZV in Columbia not cause microcephaly, it is actually preventative. Pregnant women should be infected with ZV to prevent microcephaly. Or it could say that the data are warped. Or it could say that the ZV in Columbia are different than the ZV in Pernambuco, Brazil where most of the problems have occurred. It could say about anything.

And so your conclusion is: it must be because the larvacide was used in Brazil. But the original NEJM study doesn’t say anything about larvacide or where it was or wasn’t used. Was it used in Columbia? If so, then why no microcephaly in the study? The NECSI summary of the NEJM report just throws that pryifroxifen crap out there with no support, no discussion of how much pyriproxifen is used, or where in Brazil it is used (relative to Pernambuco), or whether it is used in Columbia. They don’t even spell the name of pryifroxifen correctly. You gonna’ buy this shit?

Regarding your claim that “the Zika Virus is harmless:” yes, that was pretty much the standard line 2 years ago. But what you are missing is what I pointed out in February: In July 2015 just before these problems arose, the UK company Oxitec released millions of GM mosquitoes into the areas in Brazil where the microcephaly problems later surfaced. The GM mosquitos are called OX513A and they are loaded with the modified genes by way of a genetic vehicle that is notorious for jumping across species lines, and even from animals to plants. Links are provided in the previous thread.

So while you say ZV is “harmless” that generally accepted view would not necessarily apply to the virus if it has been buggered by the Oxitec gene that was put into the mosquitos and then jumped into the virus and then jumped into the human embryo. This theory suggests the same conclusion as the last part of the title of your post: fighting these viruses with GM mosquitos may be causing the problems. [Please note that neither the larvacide nor the GM mosquitos are used primarily to fight ZV. They are used to fight dengue, chikungunya, and other deadly viruses carried by various species of Aedes mosquitos.]

It seems to me that you’re on even more of an uphill slope with this post than with the previous one. But keep throwing shit at the wall, something will eventually stick. I know, you should see my wall.

From the little biology that I know, production of retinoacid during initial days of embryonic development initiates the formation of the precursor of the central nerve system. The presence of similar but not identical molecules can confuse this process. To check if it indeed may happen, I guess one would need to try different doses applied to pregnant mice. Retinoacid is metabolized inside the embryo, and the transmission of the potential damaging molecule from the mother blood to the fetus may depend on various factors -- in principle, there is placental barrier that protects the fetus, and it may work better or worse.

In principle, new harmful mutation of microbes happen from time to time. Recently, most of quarter million saiga antelopes in Kazakhstan died within few months of what appears to be a lethal epidemic of microbes that were not particularly deadly before. Wikipedia entry on pyriproxyfen quite firmly rejects the possibility of this insecticide being responsible for microcephaly. It is actually used worldwide so localization of elevated levels of microcephaly in Brazil and few other places cannot be explained by pyriproxyfen. Its impact on mammalian embryos was actually studied. This is not conclusive because Wikipedia can be subjected to skillful manipulations (and the same may be the case with the studies where billions can be at stake), but the arguments in Wikipedia actually seem sensible. Tests or the interpretations can be biased, but geographic distribution of pyriproxyfen use and incidences of microcephaly are harder to manipulate.

Lastly, it is very difficult to figure out what is different between different strains of a virus. Zika is apparently harmless most of the time. When you compare viral genomes, the problem is that there are too many differences between strains, so it is hard to determine which may be responsible for conjectured pathogenic effect (and test it on a suitable animal model???). Therefore the only "proofs" are of "correlation is causation" kind. Half of biology is like that. Combined with the analysis of possible confounding factors, it can provide convincing arguments (the word "proof" is rarely used in papers on biology).

Most insecticides happen to be small molecules that mimic hormones or signal molecules in insects that disrupt normal metabolism or cell function. Most of these processes are not unique to insects but are also present in vertebrate including humans. What makes them insecticides is that insects are more sensitive to them than are mammals. It is called differential sensitivity. At some higher concentration they will be toxic to mammals. What b is alluding to is that direct addition of pyriproxyfen to drinking water has resulted in higher exposure of this compound to humans than would result from simple treatment of plants and soils for farming purposes. I have no idea how this compound has been used in the past or even if it had used directly in drinking water before. But it is quite plausible that a previously safe insecticide would be toxic to humans if the exposure was increased.

It's basically too early to be making a call.

Three sources of which two doubt the connection, and the third believes it's real.

"The Zika virus has spread rapidly in the Americas since its first identification in Brazil in early 2015. Prenatal Zika virus infection has been linked to adverse pregnancy and birth outcomes, most notably microcephaly and other serious brain anomalies. To determine whether Zika virus infection during pregnancy causes these adverse outcomes, we evaluated available data using criteria that have been proposed for the assessment of potential teratogens. On the basis of this review, we conclude that a causal relationship exists between prenatal Zika virus infection and microcephaly and other serious brain anomalies."

In a few months the issue will almost surely be settled - one way or the other. What's the rush to make a decision now?

Posted by: Zachary Smith | Jun 26 2016 22:27 utc | 30

It is my belief that the Zika virus, corruption at FIFA, Russian drug use in sport etc are all connected.

The USA is behind all of these things. When the US declares war on a country, it is total war, and the media leads the charge every time.

The US wants to pillage Latin America, again, and destroying their economies allows the US to buy up the assets of the victim country very cheaply.

I am not sure what the cause is. This is from the CDC: "Recent media reports have suggested that a pesticide called pyriproxyfen might be linked with microcephaly. Pyriproxyfen has been approved for the control of disease-carrying mosquitoes by the World Health Organization. Pyriproxyfen is a registered pesticide in Brazil and other countries, it has been used for decades, and it has not been linked with microcephaly. In addition, exposure to pyriproxyfen would not explain recent study results showing the presence of Zika virus in the brains of babies born with microcephaly. ... Zika and Other Birth Outcomes
In addition to microcephaly, other problems have been detected among fetuses and infants infected with Zika virus before birth, such as eye defects, hearing loss, and impaired growth. Although Zika virus is a cause of microcephaly and other severe fetal brain defects and has been linked with these other problems in infants, there is more to learn. Researchers are collecting data to better understand the extent Zika virus’ impact on mothers and their children."
And this from NPR: "In the end, though, the most compelling point against pyriproxyfen's role in Brazil's recent health issues is this. Health officials in the state of Pernambuco say that in the three cities with the most microcephaly cases, they don't use the chemical. Rae Ellen Bichell, NPR News."

I've always thought the proper and normal use of such a larvacide was spraying it in areas of standing water; but it seems utterly absurd that it would ever be added to the public's drinking water. I can not imagine such a thing being done, as it would surely accumulate to dangerous levels in the human body.

Someone is obviously negligent in the use of this toxic substance; and the information is available that shows that the manufacturer's laboratory results, in tests of its effect on mammals, was hidden from the end users of this product.

FYI all, "noted skeptic David Gorski" is a paid CDC troll par excellence, WHATEVER he opines re any current CDC scare campaign, or actual scandal for that matter, should be read through that lens.

And Denis, the theory that the Tdap campaign which targeted rural Brazil with likely the same non-regulation and 3rd world controls as these things usually have, may have played a factor, is not far fetched at all. In fact there still may be a synergistic component to the specificity of the microcephaly cluster areas. Poor nutrition, pesticides in the drinking water(a common thing in the tropical third world), and inappropriately timed assaults on the maternal immune system can absolutely lead to fetal disaster.

The bottom line is that there still haven't been any first world "Zika microcephalies". Maybe if the CDC had kept their begging bowl hidden for a more appropriate amount of time - they immediately asked for nearly 2 billion in research dollars, and this is just for the preliminary stuff- the whole fauxdemic would have a truthier feel, but just like every other collapsing, corrupt revolving door agency, they are motivated by an intense greed and a hubris that comes from decades of unaccountability.

The CDC pays Gorski to troll? That's a pretty sweet deal.

It's fairly obvious to anyone who's followed his blogging "career". He remained anonymous for some time going by the moniker "Orac".

And he's not the only one. The whole "vaccine" controversy has created some epic paid/pro trolls. A few even do it with their real names; academic Dorit Reiss, who did a thesis on "The Benefits of Agency Capture" before going full bore in defense of the CDC's whacky pediatric vaccine schedule, being the most notable example.

b. Good read on the weasel words like "may" used in the place of science. I see it all the time. People see the story but don't think about the weasel words used to push for links (agendas, beliefs) where they MAY not exist. The media love to sensationalize something to pretend they were on top of it all the whole time.

Many of the big outbreaks have been manufactured in NATO laboratories or earlier in the USA (e.g. Fort Dettrick, MD) and UK - that's been part of the anti human genocidal Tavistock/City agenda all along.

"Spanish flu" started in the US, same with the "swine flu" in the 70s. AIDS is an artificial creation. Ebola has been weaponized and spread around Africa by some intelligence agents - CIA, MI6, Mossad, Bill Gates "philanthropic" foundations vaccination campaigners (it couldn't have spread in such a pattern naturally). People outside the West know that, some prominent figures talked about it (a Chinese general about the "bird flu" aimed against the "yellow race").

And the war profiteers even revealed themselves in the PNAC "Rebuilding America's Defenses" prophetic report (the same that called for "some catalyzing event like new Pearl Harbour" shortly before the 9/11) where they write about need for "biological weapons targeting specific genotypes"

It seems that something BIG is being prepared for the Olympics in Brasil, now with the Dilma Rousseff out of the way, the judeo-masonic lobby has full control of the security apparatus. Expect "false flag" operation by the AngloZio cabal on an unprecedented scale.

Incas, Aztecs, Mayans were all microcephalic.
Look at every ancient carving.
They all have pin heads under their headdress.

They make them build pyramids to keep them occupied.

Your idiotic and racist comment adds nothing to the conversation.

Sculpted works of various cultures are not necessarily accurate guides of how their creators looked, especially if realism is not prized in those cultures and idealism and symbolism are the goals of art.

Some indigenous American cultures are known to have shaped babies' heads to achieve sloping foreheads. As far as is known, shaping children's heads doesn't affect brain capacity. More worrying, I should think, is the amount of cosmetic surgery people resort to, to achieve Barbie-doll appearances or hyper-masculine figures and the level of intelligence this implies.

Zika Virus Does Cause Birth Defects, from sciencedaily (June, 28):

Five new confirmed microcephaly cases in Colombia may be harbingers of epidemic

Just when it seemed that missing cases of microcephaly in Colombia were straining the credibility of the Zika virus' connection to the birth defects, the latest report from Colombia includes five new cases of microcephaly with Zika infections.

I love all people

I believe the 10 commandment were the simple rules for existing here. follow them and you don't have to come back here.

That we were supposed to be stewards of this place not it's parasite.

I believe ebola, zika, dengue, plague etc etc etc are all forms of earth's immune system trying to react to our toxic effects here

I believe zika pursues dominance to balance to species of the planet. That if it cant do its job in a mosquito it will go to sex. If that doesn't work then it goes after our food then it'll switch to fleas. whatever it needs to do to balance the planet. until we are humble again.

and when I say we I mean you. because I am following the 10. not going to be fun here next time around

I also believe that spraying mosquitos is how we destroy all the bees, depleting our ability to feed the planet because crops don't self germinate

That there are 14 to 18 million homes for sale in America. Most are bank owned.

That by collapsing more southern countries it will flush more home buyers north here.

At least the ones who can afford to escape their country and have the wealth to purchase

That the void of integrity at every political level in the world will be the thing that kicks it all off soon because they will serve themselves first making money worthless. remember we all elected attorneys not servants

150,000 walked into columbia looking for food 2 days ago

google ancient or old pictures of aztecs you ll see
read the letters the conquistadors sent back to the king of spain
how else could a few hundred sailors kill thousands and thousands mayans, aztecs etc MULTIPLE times
they were a pygmie like race due to uncontrolled zika
those weren't human sacrifices they were trying to eliminate people infected with zika so they would quit producing micro babies
re: africa where people cant stop making starving babies
it burdens the society more than it can stand
see thousands of unoccupied ancient cites around the world

now go look at all the pyramid carvings around the world - troll like beings are carved at everyone of them

get on the 10 or begin again

the trick to zika don't let the mosquitos get infected but its too simple and we are too stubborn to keep ourselves from altering our path to protect the insects.
we think spraying pestilence all over the world so we dont have to alter our work and shopping schedule or trying to alter the genetic structure of another species makes WAY more sense

if youre unclear of my context at in point imagine it all in goofy's voice but with the utmost sincerity (seriously read it with goofy's voice. ha enjoy)
