Is the 6ME Hyperbole?

Posted on by
Unrealistic image from Easy-Peasy.

Many of the stark conclusions I offer on Do the Math and in conversations with others rest on the equally stark premise that we have initiated a sixth mass extinction (6ME). Other self-defeating factors also loom large in establishing modernity as a temporary stunt, including resource depletion, aquifer exhaustion, desertification and salination of agricultural fields, climate change, microplastics, waste streams, “forever” toxins, and plenty more. People do call it a poly-crisis, after all (I prefer meta-crisis as most symptoms trace to the same root mindset of separateness and conquest).

Yet, towering over these concerns is a sixth mass extinction. Mass extinctions are defined as brief periods during which over 75% of species go extinct. I take it as given that large, hungry, high-maintenance mammals like humans won’t be among the lucky survivors—who are more likely to hail from families like microbes, mollusks, arthropods, or otherwise small, scrappy critters. In any case, it’s bad…very bad.

Invocation of the 6ME serves as a final nail in the coffin…end of story…to be avoided at all costs. All the aspects we like about modernity lose appeal when held up against the 6ME as a direct consequence. Even though the other challenges listed above can carry the argument as well, they generally must do so as a set, and we’re not so talented at apprehending parallel concerns—imagining each to be surmountable in isolation (pointlessly; it’s whack-a-mole). The 6ME delivers a single, inarguable, fatal blow to modernity, which is why I have taken to invoking it as a heavy-handed “nuclear option” straight away. No point playing around. While it may seem extreme, extreme circumstances justify extreme responses.

But is the threat real, or rhetorical? Basing arguments against modernity largely—though not entirely—on the 6ME could amount to overblown doomerism. In this post, I challenge myself on the veracity of 6ME claims. Have I fallen into a false sense of the urgency of this moment? Do I really believe a 6ME is going to play out?

The Genius of Survival

By accident, my wife and I stumbled onto the convention of calling essentially every living being a genius. It started as a joke about our cat, because obviously—in our human-supremacist culture—superlative traits like genius can only be applied to humans! Soon enough, this practice migrated to squirrels, newts, baby birds, ants—and even plants, fungi, and microbes. I no longer think of it as a joke.

I’ve utilized this framing in other posts by noting that every one of these beings knows how to do things we haven’t the foggiest clue how to do ourselves—or how, in detail, they manage it. I’ll get to the nuanced nature of the word “know” in a bit. But for now we can at least admit that the world is overflowing with phenomena we haven’t even registered, let alone understood. Typically, we just scratch the surface at best.

What I’ll do here is explore the relative genius of Life as compared to the normal use of the term, in the way of cognitive prowess. Let the games begin!

For the Love of Newts

Happy Newt Year! Those who have followed me for a long time have probably noticed a marked uptick in the frequency of newt mentions in the last few years. What’s the deal with that? It seems so random. Am I engaging in occult practices that require eye of newt?

The simplest version is that when I moved from San Diego back to the Pacific Northwest (had lived in Seattle prior to being “rented” by California for 18 years), I landed in newt territory.

My street is largely undeveloped, leaving plenty of forested critter habitat. A slow-moving creek—dammed by beavers into more of a pond—runs a few hundred meters away, which anchors the local newts. When it rains, especially in fall and spring, we find newts slowly prowling the area. Just as lost keys are more likely to be found under a lamp-post simply because light allows them to be seen, newts are frequently found on streets and driveways because they stand out on such plain surfaces. I suspect it goes deeper than this, in that they also hunt worms, which find their way onto pavement during the rain, and are also perhaps easier for the newts to spot. Rainy time is dinnertime!

I could never have predicted it a few years back, but my wife and I find ourselves smitten by the newts. We love and adore them. I hope this post provides at least a little appreciation as to why.

Egregious Inequality

We’ve all heard the outrageously skewed statistics. The top 1%, or 0.1%, or even 0.01% of humans control an outsized fraction of total wealth (something like 30%, 15%, and over 5%, respectively). Because our culture values the fictional construct of money far more than is warranted, and the ultra-rich have a hell of a lot of it, they acquire status and access to power unavailable to almost everyone else. How can such a small fraction of the population possess such a disproportionate share of this resource—one that we’ve decided bestows influence and power? It doesn’t seem at all fair.

But, money isn’t the only disproportionate power-conferring asset on this planet. What else does our culture value above almost all else? Brains. What—are we zombies?! Large brains are what (we tell ourselves) set us apart from mere animals—taken to justify a sense superiority. Earth belongs to us. We can do whatever we want, because we’re the ones with the big brains: the self-declared winner of evolution—as if it’s even possible to have a winner in an interdependent community. Through innovation and technology development, we now wield god-like power over the rest of life on Earth—for a short time, anyway, until it becomes obvious that “winning” translates to “everybody loses.”

Given our similar tendencies to overvalue money and brains, I was motivated to compare inequality in brain mass within the community of life to the gross inequality we abhor in financial terms. Is it as bad? Worse? Humans constitute 2.5% of animal biomass, and 0.01% of all biomass on the planet. We are also one of perhaps 10 million species, which in those terms means we represent only 0.00001% of biodiversity. Any way you slice it, we are a small sliver of Life on Earth—while managing to dominate virtually every ecological domain. As our culture tells it, humans are the deserving elites.

What fraction of the planet’s brain wealth do we possess? To be clear, in performing this analysis, I am not making the case that brains are what matters—far from it. But in our culture, our brains are cherished and essentially worshiped for their unique capacity in terms of ingenuity, allowing us to defy the limits that all other species “suffer.” What is our disproportionate share of brain mass? Is it as bad as 15% or 30%, like our egregiously-lopsided wealth inequality?

MM #7: Ecological Nosedive

Posted on by

This is the seventh of 18 installments in the Metastatic Modernity video series (see launch announcement), putting the meta-crisis in perspective as a cancerous disease afflicting humanity and the greater community of life on Earth. This episode will try (and probably fail) to convey the degree to which Earth’s biodiversity and ecological health are in peril.

As is the custom for the series, I provide a stand-alone companion piece in written form (not a transcript) so that the key ideas may be absorbed by a different channel. The write-up that follows is arranged according to “chapters” in the video, navigable via links in the YouTube description field.

MM #5: Our Biological Inheritance

Posted on by

This is the fifth of 18 installments in the Metastatic Modernity video series (see launch announcement), putting the meta-crisis in perspective as a cancerous disease afflicting humanity and the greater community of life on Earth. This episode extends the point from Episode 3 that we owe almost everything to life that came before us. All our senses and capabilities are inherited. We would be nothing without our older brothers and sisters on this planet.

This is the third in the Metastatic Modernity video series of about 17 installments (see launch announcement), putting the meta-crisis in perspective as a cancerous episode afflicting humanity and the greater community of life on Earth. This episode stresses that humans are nothing without the menagerie of single-celled pioneers whose many clever solutions to life we still utterly depend on today.

They Didn't Stand a Chance

Posted on by

My apologies for such a dismal post topic, but modernity made me do it. I’ve borne witness to a number of the following tragedies first-hand. When exposed to similar atrocities in your own life, I recommend repeating the mantra that appears at the end of every point below. I think it helps in fighting human supremacism, validating other life and recognizing the pain we inflict—often unwittingly as we animate the maw of modernity. Evolution did not prepare the plants and animals of this planet for a sudden and dramatic up-ending of the world they were customized to inhabit. That’s on us.

Twenty Terrible Tales

A massive tree that took hundreds of years to attain tremendous height and bulk was no match for an hour of chainsaw action. It did nothing wrong, but didn’t stand a chance.

A gangly moose was minding its own business in the willow thicket along the stream edge, when—BAM—its head was taken to grace the lodge wall. It did nothing wrong, but didn’t stand a chance.

Domesticated bees were bred to produce more honey and be less aggressive. Weakened against parasites and disease, their colonies crashed. They did nothing wrong, but didn’t stand a chance.

A deer, finding itself on a strange, hard, flat ribbon stood transfixed as two unearthly lights sped closer, seemingly set to pass on either side. It did nothing wrong, but didn’t stand a chance.

Orangutans who lived for countless generations in the dense and biodiverse rainforest found their home destroyed and replaced by oil palms. They did nothing wrong, but didn’t stand a chance. [Warning: only watch the link if you are ready to be haunted for life by seeing the skinny, muddy “bean” at the end of all things.  It grieves me to my core.]

A butterfly created a caterpillar who had the misfortune to eat pesticide-coated leaves, undergoing metamorphosis into a dead lump. It did nothing wrong, but didn’t stand a chance.

The noble forebears of our dumb-bred domesticated (captive) animals had no evolutionary answer to ropes and tall fences. They did nothing wrong, but didn’t stand a chance.

The chattering swallows returned in spring to raise a new set of chicks. But the local mosquitos had been exterminated, leaving the parents and chicks to starve. They did nothing wrong, but didn’t stand a chance.

An 80-year-old tortoise followed the familiar route through the forest, across a road that wasn’t there in its youth, just as a truck came along. It did nothing wrong, but didn’t stand a chance.

The wasps weren’t bothering anybody when they went about their business raising young in a nest under the eaves, only to be shot by a 3 meter jet of poison. They did nothing wrong, but didn’t stand a chance.

Native grasses and flowers tried to restore health to a corn field, only to be coated in herbicide dropped by an airplane. They did nothing wrong, but didn’t stand a chance.

Crabs, lobsters, clams, and oysters found that they were no longer able to make protective shells in more acidic water, ultimately perishing from this earth. They did nothing wrong, but didn’t stand a chance.

A rough-skinned newt, in bursts of slowness, made its way across a wet road at dusk, only to have its innards abruptly and rudely squashed out through its mouth. It did nothing wrong, but didn’t stand a chance.

The exquisite ruffed grouse cruised into a clearing, aiming for trees that turned out to be a reflection in a house window. It did nothing wrong, but didn’t stand a chance.

Salmon had fed the forest for millions of years, but demand for heat pumps, electric vehicles, and chat-bots put a dam in their way. They did nothing wrong, but didn’t stand a chance.

A large prairie dog colony had lived on this patch of land as long as anyone could remember. The commercial developer orchestrated their final solution. They did nothing wrong, but didn’t stand a chance.

The polar bear cubs got exhausted from swimming in a futile effort to find ice and seals. Their inevitable end was cold, wet, hungry, and oh-so skinny. They did nothing wrong, but didn’t stand a chance.

The foxes in the Mojave desert required large unobstructed habitat, which vast new solar farms fenced, shaded, and uprooted. They did nothing wrong, but didn’t stand a chance.

A sea turtle had no notion of the word “bycatch,” yet found itself dying in a crowded net all the same, only to be discarded as waste upon discovery. It did nothing wrong, but didn’t stand a chance.

Pursuers of modernity forgot themselves, thinking they owned and controlled the world, no longer subject to limits or part of a larger ecology. The world taught them a cruel lesson on the definition of unsustainability. They, for a change, might have known better, but as it was didn’t stand a chance.

End Note

The common thread is forcing plants and animals out of their evolutionary context, as we have done to ourselves as well via modernity.

I kept coming up with more examples, and eventually decided to stop because I felt I was beating a dead horse. It’s surprising how many more examples I could have used, and I suspect you could come up with a number not covered here yourself. It is telling that we are not running short on grim accounts of biodiversity loss.

Let's Make a Deal!

Posted on by

Several posts of mine have sought to put the value of Earth’s biodiversity in context. The first of these leveraged the cute coincidence that all the animals on the planet are about the same weight as all the gold within 5 km of the land’s surface to make the case that animals are worth more than their weight in gold.

The next installment made a similar case for insects (arthropods, more generally), placing a premium economic value of at least $10,000 per kilogram of bug mass.

In this post, I ask: what would you be willing to trade for all animal life on this planet? It may seem like a forced and false choice, as nobody is proposing to eliminate all animal life on the planet. Despite this, we’re doing a dazzlingly good job of marching toward that very goal, whether explicitly intending to or not. Typical decline rates among vertebrates and insects are in the 1–2% per year ballpark; average decline in vertebrate populations is 70% since 1970; and a sixth mass extinction appears to have kicked off with extinction rates about 1,000 times the background rate. So, the prospect of losing Earth’s biodiversity is not purely hypothetical, thus deserving serious attention. I’ll have more to say about the validity of this approach at the end.

Meanwhile, are you ready to play the game?

Nothing, Without Bugs

Posted on by

A while back I wrote a post pointing out a way to see that animals are worth more than their weight in gold. The concept was cute, but not fully defensible in detail. Yet, the many orders-of-magnitude difference in market value of animals vs. their gold-equivalent value at least indicated that we might have something wrong, on the basis that we can’t live without the animals, but could live without gold.

In this post, I will follow a similar path to arrive at what I think is even a more stark result: that the economic value of arthropods (e.g., insects) is something like $10,000 per kilogram. To get here, we need to first preview the numbers.

Dry carbon biomass on Earth, from Bar-On, Phillips, and Milo; PNAS 115, 6506, 2018.

A look at Figure 1 in a 2018 paper by Bar-On at al. (reproduced above) shows that Planet Earth hosts 2.4 Gt (giga-tons) of animals, in terms of dry carbon mass. The largest block within the animal kingdom is arthropods (includes insects, spiders, centipedes, and crustaceans), at 1 Gt. Fish are nearly as big, at 0.7 Gt. By contrast, wild mammals are only 0.007 Gt, and wild birds are a comparatively tiny 0.002 Gt.

I have pointed out before that humans now vastly outweigh wild mammals, to the point that we only have 2.5 kg of wild land mammal mass left per human on the planet (presently plummeting). Note that this is a “wet” mass figure, whereas the numbers above are dry carbon mass (about 15% of wet mass).

The trends are falling fast: insect, bird, mammal, amphibian, and fish populations are losing ground to the tune of 1–2% per year, amounting to halving populations over a handful of decades [late addition: good article on subject]. Inevitably, then, extinctions are up a thousand-fold, and increasing. This is decidedly not good, and perhaps the most glaring sign that modernity is a literal dead-end path.

The approach here is to assume that Earth’s ecology would crash without any arthropods. The same might be said for fish, or birds, or any major group. Bugs (an informal catch-all substitute for arthropods here) are particularly attractive to me for this exercise because they are so crucial in terms of food for others, soil conditioning, pollination—and other services—that it is hard to believe other phyla could carry on without them. Evolution produces a complex interconnected web that cannot be expected to maintain its overall integrity if surgically plucked apart in this way—much as an organism cannot be expected to survive if completely removing any one of many key organs.

Therefore, no bugs, no humans. No them, no us. The same argument could probably be made for other phyla, producing slightly different quantitative results than what follows, but the same in spirit.
