It looks like the Agenda 21 plan is moving along just as the ‘Control Freaks’ have planned. Birth rates are plummeting, the family has been destroyed, and people worship their government god. What could possibly be left?

Demographic Dysphoria Looms As Scientists Discover Sulfur Dioxide Lowers Sperm Count

Back in June, we explained how a demographic dysphoria looms for Central Bankers as doctors discovered sperm counts in western men have plummeted nearly 60% over the last four decades.



In an era of depopulation, Econimica’s Chris Hamiliton noted, the next business cycle recession will be unending and is very likely to run years into decades and perhaps a century or more.


We also expanded on the idea of a declining population already indebted with record debt levels and zero interest rates is a perfect cocktail for disaster.


The global problem identified in one chart provided to us via Cris Hamiliton shows the annual growth of the 0-64yr/old population of the combined OECD nations (most the EU, US, Canada, Mexico, Chile, Japan, S. Korea, Australia / New Zealand) plus China, Brazil, and Russia.


To sum up the chart, all the population growth responsible for economic expansion in the past half century is coming to an end in 2018.



So, there has to be an explanation why developed and emerging market males are experiencing lower sperm counts...


With that in mind, we think-we found- the answer in China, as a new report links sulfur dioxide to lower sperm count.


According to Yuewei Liu, an environmental epidemiologist at Hubei Provincial Center for Disease Control & Prevention, suggests that poor semen quality accounts for 90% of male infertility. Impaired semen clearly interferes with conception, but it is also often an indicator of other health problems. 


Chemical & Engineering News outlines how Liu’s clinical test demonstrates sulfur dioxide exposure to sperm development could impact sperm quality:




So Liu and his team decided to study semen samples collected from 1,759 men in Wuhan, China. They had all visited Tongji Hospital from 2013 to 2015 seeking help to conceive a child with their partners. The researchers measured sperm concentration, total sperm, and total motile sperm in each sample, controlling for factors that might affect semen quality such as age and smoking. Then the scientists drew on government data from nine air quality monitoring stations in Wuhan—a transportation hub and manufacturing powerhouse—to estimate exposure to air pollutants such as sulfur dioxide, nitrogen dioxide, carbon monoxide, and ozone. Liu employed a model that analyzed the location of the monitoring stations in relationship to each man’s home to predict individual daily pollutant exposures. Because human sperm develops over 90 days, the researchers calculated pollution exposures for the 90 days prior to semen collection so they could look at key periods of sperm development.


 


When Liu and the team used a statistical test to rate semen quality against increasing air pollution, they found no impact from NO2, CO or O3. However, for each 10 µg/m3 increase in SO2exposure during the first stage of sperm development, sperm concentration dropped by 6.5%, total sperm count by 11.3%, and total motile sperm by 13.2%, Liu says. Levels of SO2 during the later stages of sperm development did not appear to impact sperm quality. The annual mean SO2 concentrations in Wuhan during the study period ranged from a high of 33 µg/m3 in 2013 to 18 µg/m3 in 2015. In the U.S., annual mean SO2 concentration was less than 5 µg/m3 in 2013.


 


“Our results indicate for the first time that SO2 exposure may lower semen quality by affecting the earliest stage of sperm development, 70 to 90 days before ejaculation,” Liu says. He speculates that SO2 could impair sperm by triggering oxidative stress and damage to DNA. “Given the limited evidence from epidemiological and in vivo studies, further studies are needed to confirm the association of NO2, CO and O3 with semen quality,” Liu adds. He recommends caution in generalizing the findings to other populations since the men were all from one city in China.




Bénédicte Jacquemin, an epidemiologist at the health research institute ISGlobal in Barcelona, says “even though the study was limited to one city, this paper adds evidence to the existing literature showing a downward trend in sperm concentration and count with increasing exposure to air pollution”. 


Explained: Sulfur dioxide (SO2) is one of a group of highly reactive gasses known as oxides of sulfur. It is a colorless gas with a pungent and suffocating odor. It is a common air pollutant found in many parts of the world...



Global Sulfur Dioxide Monitoring map provided by NASA outlines many developed and emerging economies are currently experiencing some form of sulfur dioxide release. Here on the east coast of the United States, we are swamped with power plant expulsion of SO2, so you might want to get checked out...



Bottomline: decades of economic progres in developed and emerging markets have had its advantages, but rarely do we hear of the disadvantages in a scientific way, as what we have just learned: sulfur dioxide is a sperm killer.

Demographic Dysphoria Looms As Doctors Discover Sperm Counts In Western Men Plummeted Nearly 60%

Population growth is responsible for the majority of GDP growth...so a downturn in population growth matters...particularly when population growth shifts from wealthy or developing nations to the poorest.  I"m not describing something that may happen in the future...I"m describing what has already happened that is continuing to send progressively larger tsunamis swamping the world economy and has the central bankers doing everything and anything to try to sustain the unsustainable.


Which means, as Econimica"s Chris Hamilton recently noted, the next business cycle recession will be unending and is very likely to run years into decades and perhaps a century or more.  A declining population already indebted with record debt and zero interest rates will consume less...meaning overcapacity and excess inventories will never be fully cleared before the next downturn...and on and on and on.


But the absence of a growing consumer base isn"t just a US issue...this is a global problem.  The annual growth of the 0-64yr/old population of the combined OECD nations (most the EU, US, Canada, Mexico, Chile, Japan, S. Korea, Australia / New Zealand) plus China, Brazil, and Russia show the growth that has driven nearly all economic growth has come to an end...and begins declining from here on. 



And when importers are shrinking, exporters have no one to export to...and on and on and on.  The depopulation we are now facing is not simply a demographic issue that so many believe; the end of growth is the start of the SHTF scenario in which we now find ourselves.  While this situation offers short term nirvana to investors, the economic repercussions are ultimately disastrous.


And it may be about to get even worse.



As TheAntiMedia.org reports, According to a new analysis published Tuesday, sperm counts in Western men have plummeted nearly 60 percent over the last four decades. Though researchers say the specific drivers behind the trend will require further scientific investigation, current data suggest a link between the sharp decline and living in the industrialized world.


“The results are quite shocking,” Hagai Levine, an epidemiologist from the Hebrew University of Jerusalem, told The Guardian. Levine led the international team of researchers, who examined 185 individual studies conducted between 1973 and 2011.


The analysis, published in the medical journal Human Reproduction Update, additionally revealed that on average, Western men’s sperm concentration — the number of sperm within a semen ejaculate — is falling 1.4 percent a year. Added up, that calculates to an overall drop of more than 50 percent since the early 1970s.


“This is a classic under the radar huge public health problem that is really neglected,” said Levine. The team notes in its report that recent studies have shown an association between poor sperm counts and overall morbidity and mortality.


Unlike with Western nations, the team found no similar trend among the male populations of less-developed countries, such as those in Africa and South America.


“Therefore,” the team writes“sperm count may sensitively reflect the impacts of the modern environment on male health throughout the life course.” Researchers acknowledge, however, that far fewer studies have been conducted in those nations and that more data needs to be compiled before a final conclusion can be drawn.


While the scientific community seems to agree that the Western trend is likely being driven by a confluence of factors, one member of the team, Professor Shanna Swan of the Ichan School of Medicine in New York, told the Independent that the lack of declining sperm counts in less-industrialized nations is something that can’t be ignored.





“The fact that the decline is seen in Western countries strongly suggests that chemicals in commerce are playing a causal role in this trend, she said.



Just as startling as the trend, says Professor Richard Sharpe of Edinburgh University, is the fact that it shows no sign of slowing down. Speaking to The Independent, Sharpe, who was not involved with the research, said:





“As the authors point out, the continuous nature of the decline is of as much concern as the decline itself, given that we still do not know what lifestyle, dietary or chemical exposures might have caused this decrease.”



Calling the trend “real beyond any reasonable doubt,” Sharpe says that with more and more women wanting to have babies later in life when conception is considerably more difficult, there now exists a “double whammy for couple fertility” in Western societies.





“Therefore, looking ahead,” he said, “I can only conclude that couple infertility is set to increase. Hopefully, this new study will serve as a wake-up call for health and research authorities as well as for the public, and for young people in particular.”
