It is worth to notice here that mainly white race is affected by low sperm count and within white race WASP-s are most affected.
It looks like the wealthier you are, the lower your sperm count.
But I suspect that a small number of surviving Pygmies living far away from endocrine disruptors will be more than enough to fertilize all the women-in-need.
I bet, their children are going to be cute though...
For humans jig is going to be up once female reproduction is distorted enough not to allow to produce viable eggs (still solvable by stem cell technofix perhaps) and finally not to allow fertilized egg to be implanted and develop due to womb malfunction (good chance for no technofix here - it seems that no existing or near term tech can replace womb between 3rd and 20th week of pregnancy and even if become available would be exceedingly expensive to run).

Disagree.
Knowledge gaps and lack of labor will break many interdependend links required to keep high tech going.
Infrastructure will dissipate and critical materials necessary to build advanced electronics will no longer be manufactured. Expertise is also going to be largerly lost.
Though power grid and 1930-ties tech may well prevail.

I remember, in the 1990s ufo boom, there was an ufo contactee person in morning tv show. The ufo contactee said to tv host that "Space aliens told me that if humans continue their current lifestyle, they'll become infertile." Tv host told the ufo contactee angrily to not to talk crap. I guess the space aliens were right after all.

Common mistake, you associate civilization with the 21st century apex we crrently have. Civilization at its most basic boils down to food production and storage allowing people to live in villages and specialize in tasks that improve the stats of the whole. Ancient Ur and ancient Quito and ancient Kyoto were all civilizations with technology far short of the 17th century level you speculate about. Reality is we know how to build far more efficient sailng ships than the people in 1750 built using no tools not part of their civilization tool kit. The same is true of germ theory, boiling medical instruments or soaking them in high proof alcohols distilled from common beer does wonders for reducing infection rates.

Basically with knowledge and fire you can live a quite successful early 20th century lifestyle. You might have steam power based on fire if you have access to fossil coal deposits, or you mght be limited to just biofuel supply limits, but with fire you get metal working and all the things that come with metal. If you have access to fossil fuels for your steam tech you can get to town scale electricity very easily. Wth even minimal electricity and metal working you get radio tech, and with just a little more you get TV. How far you go technology wise with fire as your starting point depends on access to flammable resources you can use. Depending on demand you can actually supply electricity with biofuel powered boilers quite well, but you need a low population density to allow soace for biofuel production.

Modern wheat, rice and maize are not the same plants we were growing in 1918, all three have been bread to produce far greater yields than their century ago versions. In addition to that reality a great deal of fully viable crop land in North America has been allowed to return to fallow/wild status in the last half century of megafarm style agriculture. Half the farms from Maine to Minnesota have been allowed to go back to woodlot since 1972 when Federal policy was changed to encourage mega corporate farms vs family operations. All of that land is still there and still viable farmland and if people need to grow more food it will be put back into production.

Maybe things are different in the US, but here in Ontario farm land has reverted back to forest primarily where the soil was too thin and nutrient poor to sustain farming.

In the USA east of the Mississippi it has been mostly small farms going out of business because they can not compete economically with corporate farms that use the same equipment over ten thousand acres that a 320 acre farm would need amortizing the costs and using hired labor vs family labor in many cases. Those farms that remain in my area are mostly cases of where the most successful small farmer in an area has bought up neighboring farmland as smaller farms went into bankruptcy so that they have collectively large parcels of land except it is separated into small parcels interspersed with other farm parcels from other successful farmer who have followed the same practice. Further west in the Great Plains the corporate farms are generally adjoining properties instead of being interspersed so the corporate farm can start harvesting on say the southeast corner of the property and keep going until they reach the north west corner without having to skip over other parcels. Here in Ohio a farmer has a 25 acre lot here and then two interspersed plots then another 50 acre plot and so on scattered over 10 miles of territory but totally up into a thousand acre farm more or less. When we need to put those eastern fallow lands back in service (when it becomes profitable) because earths population is still rapidly growing someone will lumber those fallow lots and put them back into productive use. Depending on circumstances they might even get government assistance through use of eminent domain practices to create consolidated large acreage farms by forcing the remaining small farms to all sell to a corporate large entity to force the farming east of the Mississippi to morph into strong resemblance of the western farm practices.

The greater yields also involve mechanized agriculture.

Also, the global population does not thrive on food alone. Likely, the Green Revolution was coupled with mass manufacturing, leading to extensive production not just of food but of medicine, construction materials, and many other components used for industrial civilization and distributed through extensive supply chains, and it is that civilization on a global scale that led to the world population increasing significantly from 1945 to the present.

Finally, even if the current population operates entirely through ecovillages, it might still be in overshoot.

Farmers.


I've seen stats that, over the last century, the percentage of Americans that are farmers has declined from upwards of 25% to less than 2%. Methinks we are going to need a lot more farmers, especially if the massive energy and chemical subsidies that support the so-called 'green revolution' go into a big decline. Just sayin'. Yes, some folks can grow a little food to supplement their diets, but I see a problem of scale, and a problem of societal entitlement (WHAT???! Me? Grow food?)

Maybe we can implement a movement; Smartphones to plowshares, eh?

Some things can change reasonable fast. For the 10th anniversary of the collapse of Lehman Brothers, the BBC has been running a series of articles about it and its aftermath....One includes the following, which in my opinion is caused by a wider (and unexpected) change in society.

Note: This just relates to the States.

1. We have fewer children, if we have them at all

In the decade since the recession, American women had 4.8 million fewer babies than demographers were expecting.

No, that isn't a typo.

"Every year when I look at the fertility data I expect the number of births to go up and it hasn't," says University of New Hampshire Professor Kenneth Johnson.

Prof Johnson says part of the fertility decline is attributable to women in their early and late 20s having fewer children than expected - in other words, my classmates and those who came after us.

And it's not getting better. The gap is getting wider - which is why he brings up a historical parallel.....

Malaria Mosquitoes Eliminated In Lab Experiments; Humans Next

This is the first time experiments have been able to completely block the reproductive capacity of a complex organism in the laboratory using a designer molecular approach.

The team's results, published today in Nature Biotechnology, represent the first time gene drive has been able to completely suppress a population, overcoming resistance issues previous approaches have faced.

The team engineered a gene drive solution designed to selectively alter a region of the doublesex gene that is responsible for female development. Males who carried this modified gene showed no changes, and neither did females with only one copy of the modified gene. However, females with two copies of the modified gene showed both male and female characteristics, failed to bite and did not lay eggs.
Their experiments showed that the gene drive transmitted the genetic modification nearly 100% of the time. After eight generations no females were produced and the populations collapsed because of lack of offspring.

If past malaria-eradication campaigns have taught us anything (see: 1950s, DDT), it is that reshaping the environment can have unintended consequences.

We have been reshaping the Environment ever since the Agricultural Revolution about 10000 years ago. We really took it into overdrive with the Industrial Revolution and especially since WWII, with Big Pharma and Mass Consumerism and the development of thousands of exotic chemical combinations and formulations.

Tommorow's Population Will Be Larger, Heavier and Eat More

(That is, until the point that it crashes...and while some grow fatter, others will be wasting away)

... An average adult in 2014 was 14 percent heavier, about 1.3 percent taller, 6.2 percent older, and needed 6.1 percent more energy than in 1975. Researchers expect this trend to continue for most countries.

"An average global adult consumed 2465 kilocalories per day in 1975. In 2014, the average adult consumed 2615 kilocalories," says Vita.

Globally, human consumption increased by 129 percent during this time span. Population growth was responsible for 116 percent, while increased weight and height accounted for 15 percent. Older people need a little less food, but an ageing population results in only two percent less consumption.

"The additional 13 percent corresponds to the needs of 286 million people," Vásquez says.

This in turn corresponds approximately to the food needs of Indonesia and Scandinavia combined.
