Small Communities: How to avoid being exterminated

 

In the "Simpsons" series, Shelbyville Manhattan is the mythical founder of the town of Shelbyville. He split from his companion, Jebediah Springfield, who had refused to found a town where cousin marriage was legal. So, they founded two separate cities: Shelbyville and Springfield. Both cities went their own ways, without interacting very much with each other except in terms of occasional raids performed by local hotheads. In a more realistic tale, however, we might have expected that the Shelbyvillians and the Springfielders would have considered each other as abominations to be stamped out and that they would have engaged in doing exactly that.

Sometimes, you really feel like leaving this madness to the people who watch the news on tv every day or keep harassing you on social media. You feel like joining a separate community, like the Amish. They don't watch TV, don't use the Internet: wonderful life. Yet, you have a nagging feeling that it might not be so easy.....

 

As things stand, many of us are starting to think about the possibility of quitting. Yes, quitting the debate on social media, quitting the insults on TV, quitting the attempt to extract a drop of rationality from people whose brain was washed away by a tsunami of folly. They think they are the majority and maybe they are. Or maybe not but, in any case, why can't you just do your thing in peace, without bothering anyone? 

Not so easy. Theoretically, democracy is about protecting the rights of minorities. But, in practice, the Western propaganda system has evolved into something that thrives on demonizing minorities, in some cases pushing for, and obtaining, their extermination. The case of the Jews in Europe remains paradigmatic: it came after decades of demonization carried out in a society that was basically democratic in terms of its political structure. 

So, if you want to be a minority, you are at risk. At a very serious risk. 

In earlier times, it was possible for non-standard groups to leave their countries of origin and simply move to other places. That's becoming more and more difficult: not only the world is full of people, but the global propaganda machine seems to be linking governments all over the world. Countries that at some moment seemed to be friendly, suddenly become heavily engaged in stamping out the abomination represented by the minority of people who think like you. 

There follows that if you really want to be different, you have to accept that you are a separate group in a potentially hostile larger community. It is a dangerous condition, but history tells us that there have been examples of minority groups surviving for centuries or even millennia. Think of the Jews, the Dhimmi (non-Islamic communities in Islamic countries), the Roma (the "Gypsies"), and the Amish as possibly the oldest example of the many minority religious communities in the United States.

The Jews are the most ancient example. Their dispersion is known as the "Diaspora." It started with the destruction of the temple of Jerusalem in 70 AD. From then on, most Jews have been living in scattered communities in Asia, Europe, and Africa. In recent times, they switched their strategy by returning to a full-fledged state. Their population is estimated at about 15 million (ca. 0.2% of the total world population).

The Dhimmi, أهل الذمة Ahl aḏ-dhimmah "the people of the covenant" are the non-Muslims living in an Islamic state. They are mostly Middle Eastern and African communities that maintained their Christian identity during the expansion of Islam, starting with the 7th century AD.  But they are also non-Christian groups such as the Jews and the Zoroastrians in Iran. Their number is hard to estimate, but it may be large: for instance from 10% to 15% of the Egyptian population is estimated to be Christian Copts nowadays. 

The Roma, also known as the Gypsies, are not so ancient as the Jews and the Dhimmi, but their existence may go back to the early middle ages as migrants from India, so quite possibly more than one thousand years. Very little is known about them until relatively recent times and even their total population is hard to estimate: it may be as small as 2 million, or perhaps as large as 20 million. 

The Amish are the most recent of the list, but still count at least three centuries of existence, having originated in Switzerland in the late 17th century, as a sect of Christian "anabaptists." In time, most of them moved to North America. They are now estimated to be about 350,000. 

All these groups didn't have an easy life and they were often subjected to various kinds of vexations and persecutions. Of the three, the Jews went through a full-fledged extermination attempt during the 20th century, after a history of local exterminations called "pogroms". The Dhimmi fared somewhat better: they are protected by the Sharia law and there are no reports of extermination campaigns specifically directed against them. But they have to pay a special tax and there are many reports of vexations and harassment against them. The Roma were repeatedly mistreated all over history and explicitly targeted for extermination during the 20th century by the German Nazis. The Amish were never under an actual threat of extermination in modern times, especially in the US where the legislation traditionally favors religious groups. But they had their troubles in the past and nobody can know what the future has in store for them. 

You may think that the hard life of Jews, Dhimmi, Roma, and Amish has been difficult enough that it is not to be taken as an example. But they are, actually, exceptions to the rule that in most human societies, anyone different is exterminated. The list is long: just take a look at the Wikipedia entry for "genocides," you'll see what I mean. 

So, how could the Jews, Dhimmi, Roma, and Amish manage to survive? There are several points in common in their strategies, the main one being to offer a low profile target to would-be exterminators. It means being not just a minority, but a very small minority that keeps to itself. That is, little or no proselytizing is allowed. It is possible to convert to Judaism for someone not born as a Jew, but it is not easy. The Dhimmi, wisely, refrain from trying to recruit Muslims. The Roma are close-knit family groups: you have to be born a Romani to be one. As for the Amish, they are more open to new recruits, but they do not make much of an effort at proselytizing, either.

The non-threatening image is helped by the rules that discourage mixed marriages. A rule sometimes expressed as "I don't marry your sister, you don't marry my sister." Then, the idea is to be poor -- even abjectly poor and also to avoid all forms of violence. 

The Roma have honed this strategy to perfection, they are often extremely poor and do not use and do not carry weapons. The Amish do the same, although they are known as gun lovers -- but they use guns only for hunting. The Jews are somewhat an exception, but their modern fame of a rich elite and of being effective warriors is recent. The condition of the Christian Dhimmi in the Middle East is similar: only recently have they developed effective militias, but they never tried an all-out clash against the Muslim majority. 

The main strategic position of these surviving minorities involves laying all their cards on the table. The way they dress, their language, their physical aspect, clearly identify them for what they are. (again the Jews are an exception, but that's modern. In earlier times, they were clearly identifiable). Deception by the minority would be seen as a threat by the majority -- it is to be avoided at all costs. 

Finally, these minorities tend to live in enclaves or traveling colonies of limited size, but not just as single families. It is probably a compromise between being too vulnerable (single families) and threatening (large groups). 

These rules have kept these separate communities alive for several centuries. But tolerance is always just one step away from genocide. It typically starts with the accusation of mistreating babies, then it moves one step up toward the accusation of eating them. It was commonly used against the Jews (and one may wonder how difficult it must have been for them to find kosher babies for their evil dinners). The Roma are commonly accused of stealing non-Roma's children (just as unlikely, considering that they have many of their own). And, finally, the Amish have been recently accused of pedophilia. (it is enough to say that it came from the "Daily Mail" to be sure that it is false, but just in case, take a look at this) 

After the "baby eating" phase, accusations may climb up to higher levels of depravity in a positive feedback mechanism well known in these matters. It does not necessarily lead to a full-fledged genocide, but it may happen if there are economic gains to be made in the extermination. A typical case is that of the Cathars, a European religious group that was common in Southern France during the Middle Ages. Their problem may have been that they owned lands in a specific region of Europe, where they also kept cattle and, probably, money and valuable items. When a papal decree allowed the confiscation of their possessions (and those of their supporters, or presumed to be), that opened up a specific interest in exterminating them. And it happened. 

Another example of a group that chose the wrong strategy were the followers of Jim Jones, who retreated to a remote jungle commune that they called "Jonestown," in Guyana. We will never know exactly what happened, but the whole community was wiped out in 1978. It is normally reported that it was the result of mass suicide, but some say they were exterminated by someone who wanted to get at the community's treasure. Like the Cathars, they had isolated themselves in a specific region, they had accumulated a certain wealth, and when they were attacked (if that's what happened), nobody could intervene to help them. 

As you see, forming your own community within a larger society is not easy -- especially in a democracy. You would have to develop a special language, live separately from the others and, most of all, be abjectly poor. And even that won't save you from the occasional pogrom. Then, if you make a mistake, you may expect the worst: not just a pogrom, but a full-fledged attempt of genocide. Not great as a prospect. 

Can you think of a different strategy? How about NOT laying your cards on the table and, instead, forming some kind of secret society? As you may imagine, this idea brings a different set of problems. We'll discuss that in a future post. 

 

Climate Change: What is the Worst that can Happen?

A Brontotherium, a creature similar to modern rhinos that lived up to some 35 million years ago in a world that was about 10 degrees centigrade hotter than ours. In this scene, we see a grassy plain, but Earth was mostly forested at that time. We may be moving toward similar conditions, although it is not obvious that humans could fare as well as Brontotheria did (image from BBC).

 

As it should have been predictable, the IPCC 6th assessment report, sank like a stone to the bottom of the memesphere just a few days after it was presented. Put simply, nobody is interested in sacrificing anything to reverse the warming trend and, most likely, nothing will be done. Renewable energy offers hope to mitigate the pressure on climate, but it may well be too late. We may have passed the point of non-return and be in free fall toward an unknown world. 

A disclaimer: I am not saying that nothing can be done anymore. I think we should keep doing what we can, as long as we can. But, at this stage, we can ask the question of "what is the worst thing that can happen?" Models can't help us too much to answer it. Complex systems -- and Earth's climate is one -- tend to be stable, but when they pass tipping points, they change rapidly and unpredictably. So, the best we can do is to imagine scenarios based on what we know, using the past as a guide.

Let's assume that humans keep burning fossil fuels for a few more decades, maybe slowing down a little, but still bent at burning everything burnable, deforesting what is deforestable, and exterminating what is exterminable. As a result, the atmosphere keeps warming, the ocean does that, too. Then, at some point -- bang! -- the concentrations of greenhouse gases shoot up, the system goes kinetic and undergoes a rapid transition to a much hotter world.

The new state could be similar to what the Earth was some 50 million years ago, during the Eocene. At that time, the concentration of CO2 in the atmosphere was of the order of one thousand parts per million (today it is ca. 400) and average surface temperature was about 10-12 degrees C higher than the current one. Note that this is an average: the high latitudes, North and South, where hotter than the low ones, nowhere life would experience temperatures so high that animals would boil alive. So, it was hot, but life thrived and Earth was a luxuriant, forested planet. In principle, humans could live in an Eocene-like climate. The problem is that getting there could be a rough ride, to say the least.

Nobody can say how fast we could get to a new Eocene, but tipping points are fast, so we don't need millions of years. We are thinking, more likely, of thousands of years and significant changes could occur in centuries or even in decades. So, let's try an exercise in looking at the worst-case hypothesis: assuming a warming of 5-10 degrees occurring over a time span of the order of 100-1000 years, what would we expect? It depends not just on temperatures, but on the interplay of several other factors, including mineral depletion, economic and social collapse, and the like. Let me propose a series of scenarios arranged from not so bad to very bad. Remember, these are possibilities, not predictions.

1. Extreme weather events: hurricanes, and the like. These events are spectacular and often described as the main manifestation of climate change. Nevertheless, it is not obvious that a warmer world will show violent atmospheric phenomena. A hurricane is a thermal engine, it transfers heat from a hot area to a cold area. It is more efficient, and hence more powerful, the higher the temperature difference. From what we know, in a warmer world these differences should be lower than they are now, at least horizontally, although vertically it is another matter. Overall, the power of hurricanes would not be necessarily increased. We may have a lot more rain because a hot atmosphere can contain more water, and this is an already detectable trend. Extreme weather events would be mainly local and hardly an existential threat to human civilization. 

2. Fires. Higher temperatures mean higher chances of fire, but the temperature is not the only parameter that enters into play. The trends over the past decades indicate a weak increase in the number of fires in the temperate zone and, of course, fires wreak havoc for those who didn't think too much before building a wooden house in a forest of eucalyptus trees. Nevertheless, as far as we know, fires were less common in the Eocene than they are now, which is what we would expect for a world of tropical forests. Fires should not be a threat for the future, although we may see a temporary rise in their frequency and intensity during the transition period.

3. Heat Waves. There is no doubt that heat waves kill, and that they are becoming more and more frequent. An Eocene-like climate would mean that the people living in what is today the temperate zone would experience summers in the form of a continuous series of extreme heat waves. Paris, for instance, would have a climate similar to the current one in Dubai. It would not be pleasant, but it is also true that people can stay alive in Dubai in Summer using air conditioning and taking other precautions. As long as we maintain a good supply of electricity and water, heat waves don't represent a major threat. Without electricity and abundant water, instead, disaster looms. Heat waves could force a large fraction of the population in the equatorial and temperate zones to move northward or relocate on higher grounds, or, simply, die where they are. The toll of future heat waves is impossible to estimate, but it could mean the death of millions or tens of millions of people, or even more. It may not destroy civilization, but humans would have to move away from the tropical regions of the planet

4. Sea level rise. Here, we face a potential threat that goes from the easily manageable to the existential, depending on how fast the ice sheets melt. The current 3.6 mm/year rate means 3-4 meters of rise in a thousand years. Over such a time span, it would be reasonably possible to adapt the harbor structures and to move them inland as the sea level rise. But if the rate increases, as it is expected to, things get tough. Having to rebuild the whole maritime commercial infrastructure in a few decades would be impossible, to say nothing about the possibility of catastrophic events involving large masses of ice crashing into the sea. If we lose the harbors, we lose the maritime commercial system. Without it, billions of people would starve to death. In the long run, the ice sheets of Greenland and Antarctica will have to melt completely, causing the sea level to rise by about 70 meters, but nobody can say how long that would take. Sea level rise has the potential for substantial disruption of the human civilization, even for its total collapse, but not to cause the extinction of humankind.

5. Agricultural collapse. In principle, climate change, may have disruptive effects on agriculture. Nevertheless, so far warming has not affected agricultural productivity too much. Assuming no major changes in the weather patterns, agriculture can continue producing at the current rates as long it is supplied with 1) fertilizers, 2) pesticides 3) mechanization, 4) irrigation. Take out any one of these 4 factors and the grain fields turn into a desert (genetically modified organisms (GMOs) may not need pesticides, but they have other problems). Keeping this supply needs a lot of energy and that may be a big problem in the future. Photovoltaic-powered artificial food production could come to the rescue, but it is still an experimental technology and it may arrive too late. Then, of course, technology can do little against the disruption of the weather patterns. Imagine that the Indian yearly monsoon were to disappear: most likely, it would be impossible to replace the monsoon rain with artificial irrigation and the result would be hundreds of millions of people starving to death. The lack of food is one of the main genocidal killers in history, directly or indirectly as the result of the epidemics that take advantage of weakened populations. As recently as a century and a half ago, famine directly killed about 30% of the population of Ireland and the toll would have been larger hadn't some of them been able to emigrate. If we extrapolate these numbers to the world today, where there is no possibility to migrate anywhere (despite Elon Musk's efforts to take people to Mars), we are talking about billions of deaths. Famines are among the greatest threats to humankind in the near future, although climate change would be only a co-factor in generating them. Famines may wreck sufficient damage to cause an economic, social, and cultural collapse. 

6. Ecosystem collapse. The history of Earth has seen several cases of ecosystemic collapses involving mass extinctions: the main ones are referred to as "the big five." The largest one took place at the end of the Permian, about 250 million years ago. In that case, the ecosystem recovered from the catastrophe, but it went close to losing all the vertebrates. Most large extinctions are correlated to volcanic emissions of the type called "large igneous provinces" that generate large amounts of greenhouse gases. The result is a warming sufficiently strong to disrupt the ecosystem. The current human-caused emission rate is larger than anything ever experienced by the ecosystem before, but it is unlikely to arrive to levels that could cause a Permian-like disaster. While volcanoes don't care about the biosphere, humans would be wiped out much before they could pump enough CO2 in the atmosphere to cause the death of the biosphere. Nevertheless, a substantial ecosystemic collapse could be caused by factors as the elimination of keystone species (say, bees), erosion, heavy metal pollution, arrest of the thermohaline oceanic currents, and others. The problem is that we have no idea of the time scale involved. Some people are proposing the "near term human extinction" (NTE) taking place in a few decades at most. It is not possible to prove that they are wrong, although most of the people studying the issue tend to think that the time involved should be much longer. The collapse of the ecosystem is a real threat: if it has happened in the past, it could happen again in the future. It may not be definitive and the ecosystem would probably recover as it has done in the past. But, if it happens, it may well be the end of humans as a species (and of many other species). 

7, The unexpected. Many things could cause an abrupt and unexpected change of the state of the system. The stopping of the thermoaline currents is a threat that could wreck disaster on the biosphere, but we don't know exactly what could happen, despite spectacular movies such as "The day after tomorrow"). Then, concentrations of CO2 of the order of 1,000 ppm could turn out to be poisonous for a biosphere that evolved for much lower concentrations. That would lead to a rapid ecosystem collapse. Then, heavy metal pollution could reduce human fertility so much that humans would go extinct in a couple of generations (we are especially sensitive to pollution because we are top predators). In this case, the human perturbation on climate would quickly disappear, although the past effects would still be felt for a long time. Or, we may think of a large scale nuclear war. It would cause a temporary "nuclear winter" generated by the injection of light-reflecting dust into the atmosphere. The cooling would disrupt agriculture and kill off a large fraction of the human population. After a few years, though, warming would return with a vengeance. How about developing an artificial intelligence so smart that it decides that humans are a nuisance and it exterminates them? Maybe it would keep some specimens in a zoo. Or, a silicon-based life would find that the whole biosphere is a nuisance, and proceed to sterilize the planet. In that case, we might be transferred as virtual creatures in a virtual universe created by the AI itself. And that may be exactly what we are! These extreme scenarios are unlikely, but who knows?

 

So, this is the view from where we stand: the peak of the Seneca Cliff, the curve that describes the rapid phase transitions of complex systems on the basis of the principle that "growth is sluggish, but ruin is rapid." We see a green valley in the distance, but the road down the cliff is so steep and rough that it is hard to say whether we will survive the descent. 

The most worrisome thing is not so much the steep descent in itself, but that most humans not only can't understand it, but they can't even perceive it. Even after the descent has started (and it may well have started already), humans are likely to misunderstand the situation, attribute the change to evil agents (the Greens, the Communists, the Trumpists, or whatever) and react in way that will worsen the situation -- at best with extensive greenwashing, at worst with large scale extermination programs.

So, we may well disappear as a species in a non remote future. But we may also survive the disaster and re-emerge on the other side of the climate transition. For those who make it, the new Eocene might be a good world to live in, warm and luxuriant, with plenty of life. Maybe some of our descendants will use stone-tipped lances to hunt a future equivalent of the ancient Eocene's brontotheria. And, who knows, they might be wiser than we have been. 

Whether humans survive or not, the planetary ecosystem -- Gaia -- will recover nicely from the human perturbation, even though it may take a few million years for it to regain the exquisite complexity of the ecosystem as it was before humans nearly destroyed it. But Gaia is not in a hurry. The Goddess is benevolent and merciful (although sometimes ruthless) and she will live for several hundred million years after that even the existence of humans will have been forgotten.
