Putting the life back in science fiction

Beavering away at geoengineering

Two down, now three (four?) EIRs to go.  Oy.  And one of the ones I commented on planned, perhaps, to install a meter-wide water line in the same busy intersection as another group is currently going to install a 240 KW electrical transmission line.  Shocking, possibly explosive.  I can only hope that the engineers already knew of the juxtaposition, even if the environmental consultants did not.

So, I want to talk about something else: peat.  And beavers.  And some really silly ideas about geoengineering.

A Bright and Shiny Future. With Mirrorshades

More avoidance.  I was going to write about the IEA’s 2017 World Energy Outlook (Vox article).  Or I could write about The Grauniad’s seven megatrends that could beat global warming” article.  Or I could write about the bright and shiny, 100% electrified future that seems to be the major global bankwagon that people like the IEA are now jumping on.  But that would be avoiding the real work.  Continue reading

One of Them Difficult Problems

I don’t know why Agent Orange’s First Official Joint Session made me think about parasites, but there you have it.  This is actually something I’ve been dealing with for awhile now, and since the problem is only going to get worse unless (and until) we innovate our way out of this particular pickle.

The problem is fairly simple: if you want a sustainable society, you need to recycle almost everything.  The problem with recycling stuff, especially organic materials, is that it makes controlling pests, pathogens, and parasites very, very hard, because they move very well in streams of unprocessed materials.  After all, a large majority of species on Earth are parasites (per Zimmer’s Parasite Rex), and we, erm, they, evolved over the last billion-odd years in a world where the elements of organic matter are recycled extremely well, give or take some oil and coal fields.  So it shouldn’t surprise anyone that our attempts at recycling and repurposing are spreading parasites and pathogens all over the place.  Continue reading

The Malthus-Boserup Ratchet

This is an idea I picked up from Patrick Kirch.  While it is used to explain population growth by Polynesian archaeologists, I’m starting to wonder if it can be repurposed to a wider context.  The basic idea starts with the notion that, just perhaps, Malthus was wrong.

The Future: resilient, invisible, and already here

“It is only too obvious that forcible extraction of agricultural products from the grower by those who produce none of their own foments conflict. Free, self-reliant families with modest needs and no natural incentive to increase food production to feed outsiders stand in the way of those seeking power. It is thus not surprising that Russia’s history from the advent of princes and Christianity to the present day has been that of passive and active resistance to the oppressors, endless uprisings, rebellions, peasant wars and brutal executions, and repressions of those refusing to recognize the “divine authority” of rulers (be it “princes” or “commissars”) or the inviolability of the official ideology (be it “Christian” or “communist”).

Russia’s story is by no means unique, but rather falls into the global pattern, since measures required for gaining control over populations that were previously independent and self-sufficient are similar throughout history and throughout the world.” (Leonid Sharashkin, The Socioeconomic and Cultural Significance of Food Gardening in the Vladimir Region of Russia.  PDF Link)

It’s fun what you can say in PhD theses, isn’t it?  That’s where the above came from.   I certainly explored the intertwined themes of appropriation, violence, resistance, and agriculture in Hot Earth Dreams, as many of you undoubtedly remember.  What we don’t often think about is how often resistance literally crops up, well, everywhere, even in authoritarian empires like China and Russia/USSR.  Or here, for that matter.  It’s about gardens, about how people feed themselves and what they do with surpluses.

The dust of ages

I came across this little bit when listening to NPR’s On The Media.  The episode is entitled “Digital Dark Age” which of course pricked my ears up immediately, as the digital dark age is something I dealt with in Hot Earth DreamsThe whole hour is worth listening to, but the weird idea I wanted to focus on is the idea of using artificially generated DNA for long-term data storage, an idea put forward by Dr. Nate Goldman in this segment.

Superficially, this is a great idea. Dr. Goldman is working on this idea as a way to store the huge amount of genomics data he has to curate at the European Bioinformatics Institute.  DNA is pretty stable and information dense, so if it’s possible to cheaply generate long DNA sequences and to cheaply read them, it’s a good form of ROM (Read Only Memory).  Dr. Goldman develops this into an idea of caching the great works of civilization in some sort of time capsule that starts by explaining what DNA is and how the code works, then progresses to simple decoding examples, and finally to the whole earth encyclopedia, or whatever is supposed to be in the data cache.  DNA is certainly more durable than known electronic digital media and is smaller than durable analog media like baked clay tablets, so superficially it has a lot going for it.

One little problem with this scenario is the idea that it’s easy to generate and read DNA.  It’s easy now, but I remember how hard it was even 20 years ago when I was in grad school.  This is a new technology.  Indeed, Dr. Goldman doesn’t think this technology will be financially viable for another decade or two, although it’s borderline technologically viable now.

Still, DNA ROM works better if we’re talking about a hypothetical sustainable civilization, as opposed to leaving some sort of time capsule for the next civilization 5,000 years from now or whenever.  DNA is not the kind of storage medium that will allow people to jump-start civilization from a hidden cache.  It’s just too tricky to read and write, even though DNA has demonstrably lasted tens of thousands of years in fossil bones under ideal conditions.

It’s even more suitable when we’re talking about interstellar colonization, where information needs to be stable for thousands of years.   Not only can the genomes of potentially useful organisms be stored as DNA, all the other information the starship needs to curate can be stored as DNA as well.

The other little problem with using DNA to store data is that having such technology widely available means that high-level synthetic biology will be available to anybody who wants it.  After all, if the equivalent of a laptop can generate as much DNA as your average genome, how many more bits of equipment are needed to twirl that DNA into chromosomes, insert it in a cell, and make a new eukaryotic life form?   Letting this kind of technology be available to the public is something that is currently forbidden, at least in current American society.   What kind of societal changes would required for people to believe that such technology is safe?

Still, it’s another possible technology for a hypothetical sustainable and starfaring civilization.  Perhaps in the future, we’ll have computers that are as much biotech as chips, where spam is something you feed your machine to support its self-repair function, rather than something you delete from your inbox.

Or maybe we should try to baked clay tablet thing…


Grasshoppers, locusts, and sustainability

This is an idea I played with near the end of Hot Earth Dreams, and since it’s the end of the year, I figured I’d post it here for you to contemplate in whatever quiet times you have around the holidays.  Full disclosure, I posted an earlier version of this thought over on Antipope (post #1565 in an epic thread!).

This has to do with species that are capable of outbreaks, such as the grasshoppers that can, under the right circumstances, become locusts.  In overly general terms, a species in an outbreak goes through what ecologists call “enemy release”–a population’s numbers grow faster than its enemies (predators, parasites, and pathogens) can kill them off.  Species that undergo outbreaks can be things like grasshoppers and locusts.  The category certainly includes invasive species that have outrun their enemies (think gypsy moths, rats, tamarisk), but even native species can undergo outbreaks, and there’s a whole history of species (like lemmings) that go through booms and busts, because they reproduce faster than their predators, and when predator numbers increase, their populations crash.

What I’d argue is that it’s worth thinking of humans as a species that is capable of outbreaks when the environment allows it.  With humans, we call these outbreaks civilization, and the only thing that distinguishes us from gypsy moths is that when we do an outbreak, it’s not just us.  Our symbionts, excuse me, our domesticated species, undergo an outbreak with us as we expand their habitat. These days, we use things like medicine, veterinary science, plant pathology, public health, and varmint culling programs to inhibit the actions of the species that would normally control our population numbers and the populations of our symbionts. When we do a good job (as now), our numbers boom and we have civilization.

There are three more points:  First, about civilization.  What we’re in now–global civilization–is the biggest outbreak we’ve so far been through.  There have been a number of former outbreaks, everything from the Roman Empire and various Chinese dynasties down to the conglomerations of Bronze Age city-states that we retroactively call empires, even though they were tiny in comparison to what we have today.  Civilization generally is local, lasts a few hundred years at most, and may or may not be immediately succeeded by another civilization.   That’s our normal form of outbreak, at least so far.

Second, I’m following the idea, put forward by environmental historians like Brian Fagan and Mark Elvin, that a favorable environment for civilization includes, among other things, a constant climate.  In that climate, people find a suite of crops and/or domestic animals that flourish, they produce huge surpluses, their populations boom, and oftentimes strongmen take over, or in any case, a rather complex, hierarchical social structure “evolves” to manage the problem of so many people living on top of each other.  When the climate changes, the civilization shrinks to stay within its favorable climate (as with Rome or China and the barbarians on their borders) or collapses (as with the Classic Maya under extreme drought).

That leads me to the third point: civilization is largely or entirely a cultural evolution, not a biological one.  Civilized people don’t seem to be genetically different from uncivilized people.  Part of the reason for this is that most civilizations throughout deep history only lasted a few hundred years before their survivors of the collapse headed for the hills again, so there hasn’t been much biological selective pressure to humans to become truly civilized.  Culture, on the other hand, mutates rapidly, so humans  have so far invented civilized cultures when the necessity arises, rather than depending on our genes to somehow know how to live this way.

This leads me deeper into the land of speculation.  Thanks to our hugely malleable cultural inheritance, humans can be grasshoppers, living in small bands of foragers, gardeners, or herders off in the “wilderness,” and actually that’s bogus, because such people tend not to separate human lands from wildlands.  Conversely, we can be civilized locusts, living as peasants, shepherds, artists, cops, politicians, businessmen, or soldiers, living on “our land” (the land that’s farmed, paved, and otherwise managed) and that’s separate from the howling wilderness out there.

Still, our hardwired belief systems, such as they are, have been more thoroughly shaped by our million-plus years of grasshopper lifestyle as foragers (synonymous with hunter-gatherers, simpler to type), versus the less than ten thousand years some of us been doing civilization.  I suspect that’s the reason why spiritual types are typically off in the wilderness when they have their great revelations, when they become prophets or messiahs and try to bring their message of how to live properly back to what feels like a deeply wrong civilization.  They’re rediscovering their grasshopper side and trying to spread it around.

Perhaps we can call this  “Grasshopper” morality?  It is the essence of the back-to-the-land movement, anarcho-primitivism, hermits going off to live in the mountains, and all the rest. When we live in small groups, “in balance with nature” (which means that all those pests, pathogens, and predators keep our numbers under control), we live under different moral and social systems than we do in civilized towns and cities.  We have to share with friends and family. We can’t use money, and the financial world is less than useless. We don’t need cops, but we have to be armed and fight for our rights and our families.  Nature is bigger than we are and has to be respected and lived with, not ignored.  And so on.

Relatively little of this non-outbreak morality really works in a civilized setting. But we get our heads screwed up, because prophets are always going out alone into the wilderness, finding our wild human morality within themselves, and bringing it back as the next new religion to save civilization. We get conflicted, because what these messengers say feels right on a deep level.  It feels like it should work for us, because genetically we’re as much grasshoppers as locusts, whatever our lifestyle.  But what works when the divine is talking in the wilderness isn’t quite so useful on busy streets.

Worse, when we uncritically try to apply grasshopper morality in a civilized locust setting, we can get into atrocities, because the would-be grasshoppers in power see civilization as a great evil that has to be cleansed and redeemed, if not ended.  Does this justify all the Machiavellian evils of civilization? Of course not. But I would suggest that there’s a grasshopper frame of reference and a locust frame of reference.  The morality of the garden of Eden probably won’t keep a city working, any more than psychopathic morality will.  We’re not hardwired to do civilization.

Now we’re facing a time when our biggest outbreak yet–global civilization–is looking increasingly wobbly and unsustainable. Just intellectually, ignoring grasshopper/locust morality for a second, I’d argue are three possible outcomes for the next century or so:

1. Our numbers crash and humans go extinct. There’s no good evidence of this ever happening to an outbreak species in the fossil record, but simplistic ecological models routinely point this out as a possibility.  Personally, I don’t think this will happen, but we can’t discount it.

2. Our current outbreak ends in the collapse of global civilization, and our species goes back to living as mostly or entirely as grasshoppers, wild humans in small groups, again.  In the deep future, when and where the environment is stable and suitable, there will be future outbreaks of civilization.  This is the scenario in Hot Earth Dreams.  I must add that I don’t mean that our few descendants will all be hunters and gatherers, and there’s no reason to think there won’t be villages of farmers and groups of herders after the collapse.  It’s more a matter that people will live in small groups (<200 people) with little or no hierarchy and little specialization of roles, whatever their ecological lifestyle happens to be.

3. We somehow make our outbreak sustainable, and having lots of civilized humans around becomes the new normal for Earth. While this may sound weird, other species have actually pulled it off, starting with cyanobacteria, and going on to things like ants, termites, and sauropods (those giant, long-necked dinosaurs). In each case, the outbreak basically rebuilt some part of the Earth’s biosphere, either temporarily (with the sauropods, who pulled it off for hundreds of millions of years) or permanently (as with the cyanobacteria, who rebuilt the atmosphere as a side effect).

Number 3 is what we mean by “sustainability.” When we talk about sustainability, we’re trying to make civilization the new normal, rather than have it be the crazy, unsustainable locust version of our normal grasshopper humanity.

Sustainability might work.  Personally, I don’t think it will work in the short term, which is why  Hot Earth Dreams is about a future in which humans normally live as grasshoppers in a continually changing world, becoming civilized locusts in the times and places where the climate stabilizes for hundreds to thousands of years. This vision much more complex than the simple boom/bust cycles of lemmings, but I think it’s our most likely future.

Still, a sustainable, global civilization might be possible.  Eventually.  It took over a billion years for cyanobacteria to make the world safe for aerobic multicellular species, and it might take ten million years or more before Earth’s species have coevolved with us long enough that civilization becomes normal, even when the climate changes.

I think it’s rather less likely that what we have now will last ten million years, but it’s possible.  It’s a goal worth working towards, but we need to think about just how enormous making civilization normal truly is.  This will be the first time we’ve tried it as a species.

The other thing to think about is how to deal with the evils of civilization and what to do about them.  From a grasshopper’s view, what locusts do is totally, destructively crazy and evil, yet they get away with it for awhile. Locust morality isn’t grasshopper morality, because what works with a locust swarm is horribly destructive for a small group of grasshoppers and (apparently) vice versa.

If you want  sustainable, large-scale civilization, then you’ve got to deal with our cultural inheritance as civilized beings, even when it conflicts with our biological wiring.  In other words,  you’ve got to accept that there’s something that feels totally absurd and possibly evil about us when we’re in outbreak mode. Living as civilized people, we have to have laws, justice, rules, bosses, and and all that, even when it feels  wrong. The critical point is that, if we want to continue civilization, we have to be very thoughtful about which parts of our deep-seated grasshopper morality we use, because they won’t necessarily work in a civilized context. Even though things feel weird, pointless, or wrong sometimes,  you’ve got to help make it work along with the rest of us, into the indefinite future, until human nature has finally changed enough for it to feel right.

And let’s not talk about #1.  I think all species deserve to exist, including our own.  We’re not irredeemably evil or inherently good.  We’re just another weird species that’s been suckered by evolution into existing, and even though we’re imperfect, we deserve our shot. Genocide is evil.

So if you want civilization to become sustainable, it’s probably less important to trust the Force and let it guide your instincts, and rather more important to go to those boring committee meetings and do the tough work of keeping things running on your watch.  After all, we’re still quite new at this whole civilization thing, and we’ve got to figure it out collectively.  Feelings aren’t wrong, but they’re not necessarily right either.  To make civilization work, we need both our heads and our hearts.

Happy holidays, everyone.
