The BBC reports that sperm quality continues to drop. Specifically, researchers "found a 52.4% decline in sperm concentration, and a 59.3% decline in total sperm count in men from North America, Europe, Australia and New Zealand." While alarmist publications tout this as a 60% drop, the decline is accelerating and the researchers are concerned that inaction may lead to species extinction despite the effect not being observed in regions with high machismo, such as South America, Asia and Africa.

The study "aggregates 185 studies between 1973 and 2011, one of the largest ever undertaken." It supposedly overcomes selection bias occurring from patients attending fertility (virility?) clinics and selection bias of null results not being published in journals (churnals?). My intuition is that insights can be gained from studying transsexualism. Practitioners claim patients increase at the rate of 15% per year (doubling every five years), over many decades and with no end in sight. This is akin to Moore's law, Kryder's law, Butters' law, Hendy's law, Rider's law, Carlson's law or any other exponential halving or doubling. So, it doesn't take a genius to understand that it will become an increasingly widespread issue.

Regardless, masculine medical problems are vastly under-represented. By some estimates, spending on male medical problems is about 1/4 of spending on female medical problems. For example, when a man seeks help for a legitimate medical issue, such as declining testosterone, a patient at the lower end of the "normal" range may be denied treatment even if he is constantly exhausted.

Well, take care of yourself. Eat properly. Drink properly. Rest properly. Stay active. And if healthy food and exercise won't fix accumulated problems, consider hormone replacement. You may also want to watch two films which seem to be mentioned with increasing frequency and seem to predict our era with some accuracy: Children Of Men and Colossus: The Forbin Project. Children Of Men is the second bleakest film I've ever seen and the film I've seen most during its initial cinema release. It explores the scenario of global infertility leading to economic collapse. In addition to a nexus of cast and crew, the seamless plot and astounding compositing, the film is a fantastic example of mise-en-scène which is best explained by example.

Anyhow, enjoy the films and get your medical problems addressed.

Disclosure: People in my family are affected by virility and hormone problems. I have a professional interest in film, media encoding and art education.

    See, modern civilization with 700 million people can still have 100 productive acres per family unit, like Frank Lloyd Wright's Broadacre city writ 100x larger.

    If you're only interested in talking about things that you might see in your lifetime, we may as well get wrapped up in Donald T drama - that's what's here and now.

    If you're talking long-term, your points about wealth, poverty and population growth are very much on-point. The starving countries in Africa had huge numbers of children per family, and basic human behavior is indeed prompted to larger families in, and around times of stress and uncertainty, so that's my point about raising the bottom of the wealth pyramid out of the fear of starvation, suffering, etc. to bring about at least a reduction in the population growth rates naturally - we'll probably need to do more to start a population decline, including some economic model shifts that will be painful for some of the people currently dwelling at the tops of some of the pointy-er wealth pyramids - not that the point is to "hurt the people at the top," just that any significant changes are going to cause some reshuffling and will blunt some of the pointy-er pyramids, while sharpening others - and that leads to all kinds of political dramas as people struggle to stay "on point."

    Speaking hypothetically ideally, how fast should we return to 700 million (not a magic number, just one of many good ones, better than 7B by far) population? For minimum pain of the existing populations, it should be slow, like a steady -0.23% annual decline for 1000 years, but that would be nearly impossible to engineer in the current sociopolitical landscape with competing superpowers and hundreds of sovereign states. If you're interested in "saving the planet" it might be better to "start with a bang" and drop faster at first, like 1 child per couple fast until we're back to 2B or so, note that China's population still grew under their 1 child "policy" - effective implementation is key, and that's a big part of where taking the economic fear out of people's lives is important.

    Or, we could just de-regulate sperm poisoning industries and "allow nature to take its course" that way, but as long as people can still breed, their desire to breed has more effect on the population rates than their raw ability to breed based on sperm counts.

    Well, that and the massive improvement of the majority of humanity on Earth through a variety of things that aren't supposed to do that, like capitalism, globalism, and free trade, to name a few bugbears that people keep speaking of. My prediction is about half to two thirds of the world's population will be considered developed world in 2050. That includes the typical negative population growth common to native populations of developed world countries.

    There's too much of the world that is improving too fast. China is the obvious example, but it's far from the only country out there getting better rapidly.

    If you're talking long-term, your points about wealth, poverty and population growth are very much on-point.

    I don't believe 2050 is very far away. Moving on, I believe by 2100, less than 10% of the world's population will live in countries that have a standard of living worse than the best today, Norway (better wealth, health, and education). And they'll get that way through the processes you've discounted so far.

      Calling China and India 50% "developed" by 2050 is optimistic, maybe possible if all you need for "developed" is running water and electricity - but there have been plenty of false starts with fast-track development of large populations, the first thing coming to mind being the poisoning of massive tracts of farmland in India by the powered pumping of arsenic rich groundwater out of boreholes.

      If you're including villages in Africa that have an internet hut with a solar powered satellite connection to the net as "developed," sure, we'll probably get to 50% before 2050. Tech like cell phones and internet access are spreading like fire, and are probably more beneficial than fire was when it was introduced; and with fewer downsides for what's left of the natural ecosystems.

      Will this all lead to a "soft landing" where we don't need disease, wars and starvation to stabilize the population? Barring some Kurzweilian singularity that somehow uploads my consciousness to a computer, I think I'll be out of the physical awareness arena by approximately 2070, and I think we're in for some bigger shit-shows between now and then - the mass extinction event shows no signs of slowing, and capitalism, globalism, and free trade aren't helping much at all on that front. I don't personally believe there will be any population reductions before 2070, and as we squeeze harder on the natural resources, things like economically imposed vegetarianism for 50%+ of the population seem inevitable. I lived in Texas, and I can tell you that all 27 million of 'em would rather watch the world burn than give up their BBQ, and they're not alone.

        Calling China and India 50% "developed" by 2050 is optimistic

        No, I think they'll be much higher than 50%. Let us keep in mind too that every current developed world country has both backwards and poor populations. That's not what makes them developed world. Massive infrastructure, legal systems, and high per capita net wealth is what makes the developed world what it is.

        but there have been plenty of false starts with fast-track development of large populations

        I'm not speaking of false starts, but rather economic development similar to how the US, Europe, and Japan did it. These countries are fundamentally changing due to global trade and their growth will in turn fuel economic growth in other countries that trade with them.

        I don't personally believe there will be any population reductions before 2070, and as we squeeze harder on the natural resources, things like economically imposed vegetarianism for 50%+ of the population seem inevitable.

        Unless, of course, all that new infrastructure that will be built over the next 33 years means they don't have to do that.

          India, and to a lesser but still significant degree China, have "bright spots" of development intermingled with huge populations of underdeveloped infrastructure. Where you draw the line is important if you're going to hit any particular goal. Ability to travel to an international airport and get a flight to (insert arbitrary major city: London, New York, Los Angeles, Sydney, Shanghai, Tokyo, etc.) within 24 hours might be one definition of "developed" that gets to be hard to meet if you require the people to do it with their own resources. Sure, with a month of prep time and unlimited funds, most of the world is accessible by that measure, but if you ask someone in rural China to get themselves to Sydney using nothing but the resources they command, and less than their annual disposable income, a whole lot less of the world is capable of that.

          economic development similar to how the US, Europe, and Japan did it.

          but without the massive depletion of natural resources and dependence on cheap foreign labor, because: when everybody is developed, there's no underdeveloped world to "offer wonderful opportunities" of exploitation to.

          And, no amount of infrastructure development in the next 33 years will be able to provide beef brisket sandwiches for lunch, daily, to 10 billion people, not on this planet.

            I believe this will become the golden age of human labor similar to the US's situation in 1950 and 1960.

            Which is patently false. What is "beef", for example? It's a food, not flesh of a dead cow raised in a particular way. We can grow artificial beef and skip the moderate inefficiency of pasture-based cattle agriculture.

            But even if we decided that we have to grow real cows and everyone has to have that beef brisket sandwich every day, there's ways to do that more efficiently than present. For example, cows could be grown under the cities with both the waste food stream from human food and hydroponic based agriculture. Cows aren't that inefficient. That would get past land use constraints, at least for 10 billion people. At some point, it would of course be more economic to switch mostly to protein sources with a smaller land footprint, but to outright claim that we couldn't restructure our societies to consume vastly more beef than we currently do, ignores that we can optimize a lot further along those lines than we currently do. It just costs to do so.

              First, 26.99M out of 27M Texans will NOT accept vat grown protein as beef, regardless of how convincing it might become.

              Second, industrial farming of poultry and pork is already so revolting that large portions of the population that can afford to get non-factory-grown eggs, chicken and pork are electing to do so with their wallets. Same for slime-pond-grown fish. Sure, you _could_ scale that idea up and grow cattle underground, but, are you actually calling that positive progress? My favorite quote from a factory chicken farmer: "that's the smell of money." If you've never smelled a chicken factory in person you should, just for a little perspective of how that kind of money gets made.

              Finally, why beef brisket sandwiches? By the 1970s, the hamburger was the worldwide sign of prosperity - of American wealth and largess, and back then the 1/4 pounder was the "big" burger. By the late 1990s, the 1/4 pounder became the smallest burger on most menus, and what people have really wanted all along is sliced beef, not ground and homogenized like some vat grown stuff - maybe we can't all afford it every day yet, but if we're going to continue on this illusory wheel of progress that's what's coming next: open range, grass fed, prime cut beef as often as you can afford it, and if you're not eating it at least 3 times a week, well son, you're just not living in the first world, are you?

              1/4lb per day is roughly 100lbs per year, per person. With modern application of hormones, etc. you can grow about 320lbs of beef per year per acre on good pasture land, so, per capita, just the beef of that "modest" by current standards daily 4oz hamburger for lunch requires about 1/3 of an acre of dedicated good pastureland, plus processing, packaging, transport and preparation - which is using copious quantities of fossil fuels in today's implementation of the global marketplace. Say population peaks around 12B, that means we'll need 4B acres of pastureland, just for lunchmeat, if we're all going to live like rich 1980s non-vegetarian Californians. Sound high? We're already grazing almost double that amount of land (mostly due to low quality forage growth), and there's not enough productive grazing land on the earth to double that again: http://news.nationalgeographic.com/news/2005/12/1209_051209_crops_map.html [nationalgeographic.com]

              The primary technology that "proved" Malthus "wrong" was phosphate fertilizer, like what's coming from this https://goo.gl/maps/SELTofqKwRG2 [goo.gl] area of strip mining that presently supplies about 1/4 of all phosphate for fertilizer worldwide. Phosphate has its limitations, and undesirable side effects https://en.wikipedia.org/wiki/Dead_zone_(ecology) [wikipedia.org] , and it's not opening huge productivity increases the way it did in the 1700s through the 1900s when mining it became cheap. Even if you move the cows into (absolutely disgusting to even imagine) underground pens, they've got to be fed from something that grows on solar power, maybe vats of algae would be more productive than grass, but, again, who really wants to go there?

                  I took Malthus' main point to be that there's a cap on how much population the world can support (and discovery of the "New World" was a big blow to his initial calculations) - I suppose if you want to get to the inevitability of disaster side of things, the lack of effective birth control back then was another major factor.

                  As for moving goal posts - when in history have the goal posts not moved? Moving goal posts is at the core of human happiness. I know a (Texan) family with net worth in the hundreds of millions, the stress in their lifestyles is entirely self-imposed. They're not satisfied when they're working, they're not content when they're not working - they have had multiple suicides in the past 20 years, in part due to classic manic-depression, and in part due to the human condition: no matter how good you have it, happiness comes from relative improvement, and unhappiness comes from feelings of helplessness to do what you want to do. Regardless of resources, political power, etc. there are always things that people are unable to achieve.

                  I stick by the 100 productive acres thing. If you're choosing to live in the desert, you may need more, but if we reduced the human population to one family - say 3.5 generations of 2 children per couple, so ~7 people, per 100 acres of "good" forest or farmland, we'd have high enough population to maintain academic and technological progress. Some people would stay in cities, but for any that wanted to move out onto the land, there would be plenty of land to move out onto. With continuing progress, we're not far from automated small farms, which - with low population density - would mean freedom to choose whether you wanted to hormone pump your meat animals for the productivity/efficiency increases, or let them grow more naturally, because it's not a resource constrained choice where the natural option just isn't economically feasible. The whole 100 family acres wouldn't need to be put into optimized production just to feed h. sapiens, there would be enough left over for a healthy, relatively un-managed bio-diverse nature.

                  Or, we can bio-engineer monoculture crops for maximum productivity, feed them to animals kept at 1000x natural densities, reeking of filth, but productive enough to feed a larger population, etc. etc. etc.

                  Either way, the population growth will need to stop and eventually stabilize - and we're not talking cosmic time scales - 2000 years of continued growth at the rate of the last 50 will lead to a completely unsustainable human population by any method except perhaps fusion powered underground farms and continent sized multi-level cities.

                  To me, since population stabilization has to happen somewhere, it's a question of what level should it be targeted at, and, clearly, I think we've already passed the ideal level and need to plan for a way to scale back. Quality over quantity. Just because we're going to peak over 10B doesn't mean that we should aim to stabilize there.

                    Birth control is another aspect of the emancipation of women that I already described. The key assumption, Malthus had was that exponential population growth was inevitable in the absence of extreme human behavior regulation or constraints of resources. That assumption is broken not by your fertilizer example or by wheat that produces two crops a year (the beginning of the "green revolution"), but by negative population growth in native populations throughout the developed world. The former merely increases the food supply, the latter changes the game in a light weight way.

                      I'm not talking about "in Russia," or "in the USA and Europe without considering immigration," I'm talking about world population, because that's what's going to drive cell-phone and T-shirt sales, need for food, wood for fires http://www.who.int/mediacentre/factsheets/fs292/en/ [who.int] , eventual desire for hamburgers, etc. And until ALL the world's people come up to food/shelter/economic security AND make some other gains, the population isn't going to stop, or even appreciably slow growing. The happy medium and low graphs shown here: https://en.wikipedia.org/wiki/World_population [wikipedia.org] have been predicted for decades, but as the decades roll by, total world population has continued to follow the high predictions. Scroll on down to the World population milestones in billions chart - we're still at 12 years between each additional billion in population, that number has never slowed down, the slowings on the chart are future predictions. Maybe you might argue that our % annual increase is slowing because the population has grown so large, as long as we're adding another billion people every 12 years or less, I don't call that slowing at all. 1200 years of that and we've got 107 billion people on the planet - I have a hard time believing that we'll manage that kind of number with (pleasant, desirable) technological breakthroughs - that course seems destined for some measure of control by disease, famine, lack of fresh water, and straight up lebensraum, all of which lead to wars when they strike populations that control an army of any size.

                        I'll note that the graph you linked to shows the slowing of the growth rate.

                        I'm not talking about "in Russia," or "in the USA and Europe without considering immigration," I'm talking about world population, because that's what's going to drive cell-phone and T-shirt sales, need for food, wood for fires http://www.who.int/mediacentre/factsheets/fs292/en/ [who.int] [who.int] , eventual desire for hamburgers, etc. And until ALL the world's people come up to food/shelter/economic security AND make some other gains, the population isn't going to stop, or even appreciably slow growing.

                        That was my thinking as well.

                        we're still at 12 years between each additional billion in population, that number has never slowed down, the slowings on the chart are future predictions. Maybe you might argue that our % annual increase is slowing because the population has grown so large, as long as we're adding another billion people every 12 years or less, I don't call that slowing at all.

                        I do call that slowing because it is. Population growth is exponential. A linear rate like that actually indicates a substantial decline in population growth rate.

                        1200 years of that and we've got 107 billion people on the planet

                        Only if humanity continues to have positive population growth. The above substantial decline in global population growth rate combined with both the developed world populations (excluding immigrants) having negative population growth rate and the rest of the world progressing to developed world status, indicates we aren't going that way.

                          I still call 7B too high, too stressful on the ecosystem, and until we actually start a decline, not just predict one 20 years from now (now being another moving goal post), it's still growth, even if we're "beating" the exponential trend, the natural systems that were in place for millions of years before us managed to reach an approximate equilibrium long enough to make a home for us, not by slowing growth from exponential to linear, but by finding actual equilibrium, with many many examples of not so great things happening when they didn't.

                          Stress on the ecosystem is a complicated combination of technology, lifestyle and sheer population numbers. I won't pretend to predict how that plays out even 10 years from now for technology or lifestyle. Historically, advances in technology and lifestyle have made the eco-stress-per-capita worse, not better. It hasn't been until the last decade or so that technological advances have really started (on a global scale) to hint at a true reduction in eco-stress-per-capita. Then, your (valid) argument that advances in lifestyle will bring down population growth numbers would seem to be balanced, or even outstripped by historical trends of eco-stress-per-capita as standards of living increase. Technology may, or may not, help to alleviate that any time soon - it's still far more chaotic than the observed trend in birth rate reductions correlating with lower economic stress. All this adds up, for me, to a population that won't peak under, or even near 10B, and will likely be stressing the ecosystem more like 15-20B+ people living today would.

                          The current mass extinction event isn't something that can be shrugged off, and it is still accelerating. Until humanity gets a handle on that, I'd say the population is still too high.

                            Nobody is predicting a population decline 20 years from now. That would happen somewhere in the 2050-2100 time frame. And we don't have a means in the near future to change that without killing people.

                            Stress on the ecosystem is a complicated combination of technology, lifestyle and sheer population numbers.

                            So what? Most of us realize that ecosystems will continue to be stressed for some time to come.

                            Then, your (valid) argument that advances in lifestyle will bring down population growth numbers would seem to be balanced, or even outstripped by historical trends of eco-stress-per-capita as standards of living increase.

                            I strongly disagree. The developed world countries without exception has far lower pollution per capita than the developing world. That combined with the low fertility and the setting aside of wild spaces, means that advances in lifestyle have already reduced the stress on the ecosystem.

                            All this adds up, for me, to a population that won't peak under, or even near 10B, and will likely be stressing the ecosystem more like 15-20B+ people living today would.

                            With most of the large animal extinctions happening 10k years ago, let us note. And I'm not going to collectively take blame for conditions beyond my control, such as the overpopulation issue in Africa and Asia.

                              What most of us don't realize is what the long term impact of that stress will be. It's not just about the dodo bird and carrier pigeon, it's about a crash in bio-diversity and the instability and vulnerability to plagues that brings.

                              the setting aside of wild spaces

                              is indeed a noble pursuit, but is progressing far too slowly to head off major extinction problems. I think this guy: https://eowilsonfoundation.org/half-earth-our-planet-s-fight-for-life/ [eowilsonfoundation.org] is beating the right drum, but not enough people who matter are listening.

                              The developed world countries without exception has far lower pollution per capita than the developing world.

                              All depends on what pollution you are looking at. From the polar bears' perspective, you're all wet.

                              Blame is not at issue, viable solutions for the whole planet are. Ignoring what is going on in Asia is even more dangerous than ignoring an approaching asteroid on a collision course, and we certainly wouldn't be "to blame" for that event, either.

                                Remember me talking about Pascal's wager? I already noted several actions that supposedly reduced the stress, but probably had the opposite effect.

                                I don't make predictions willy nilly nor do I expect them to be perfectly accurate. It is remarkable how dismissive people are of modern civilization despite several centuries of remarkable progress which, due to modern globalization, has now been experienced by everyone except the completely isolated. Even the poorest have better access to knowledge, health care, wealth opportunities, and technology that their forebears. And the worst problems, overpopulation, habitat and arable land destruction, societal corruption, etc has been significantly addressed by our best societies.

                                Immediate population reduction is not viable. Making the world so free and wealthy that it naturally has a negative population growth rate is viable.

                                  The really remarkable progress seems to have come in the last 100 years, fueled by non-renewable resources. It will be remarkable how unpleasant the end of cheap energy will be.
