Wild New World

 

Dan Flores is a historian who has been studying the stormy relationship between humans and the family of life for many years.  He calls this subject Big History.  Wild New World is a fascinating and disturbing masterpiece.  It’s a thick book loaded with ideas gathered over a long career.  The core focus is on North America, which was once an Eden-like paradise of abundant wildlife.  What happened?

Our species emerged in beautiful Mother Africa maybe 300,000 years ago.  Maybe 60,000 years ago, adventurous folks began wandering off into the outer world.  Our exploration of the planet was underway.  Folks went east to Asia, and north to Europe.  By maybe 45,000 years ago, folks were in Siberia and northern Asia.  So far, the earliest evidence of humans in America dates to maybe 25,000 years ago.

Flores described two important discoveries in New Mexico.  At Folsom (1908), the bones of 32 extinct giant bison, 12,450 years old.  At Clovis (1914) the bones of extinct mammoths, 13,000 years old.  At both sites, flaked flint points were found with the bones, smoking gun evidence of human hunting.  A huge surprise!

Humans were team hunters skilled at killing delicious wild animals, preferably jumbo sized megafauna.  As bands of pioneers migrated into new frontiers, a number of megafauna species gradually went extinct, in one region after another, a sequence corresponding to the timeline of human arrival. 

Today, our culture celebrates human brilliance.  We’re simply too smart to disrupt the planet’s climate — global warming is a hoax!  We deny responsibility — not our fault.  Similarly, we’re too smart to cause mass extinctions — not our fault. 

It’s much more comfortable to blame prehistoric climate change.  But the wiped-out species in America had survived for millions of years, including numerous eras of unusual heat and cold.  They weren’t dainty weaklings.  Why did this killer climate shift only exterminate large animals, not small?  Why did it just affect America, but not other continents at the same time?  Hmmm…

In the 1960s, Paul Martin began using a new technology, radiocarbon dating, a better tool for dating prehistoric artifacts.  This enabled him to compare the dates of human presence in North America with the dates of extinctions.  He learned that human arrival came first, and extinctions came later — during a process that took maybe a thousand years. 

Stunned, he referred to this process as “blitzkrieg overkill,” because of its unusual speed.  To Native Americans, this implied that their venerable ancestors foolishly hunted too hard.  They’ve never been fond of the paleface settlers who foolishly obliterated their ancient homeland, and they especially disliked Martin.

We’ve now learned that as the human diaspora advanced around the world, the same pattern followed: arrival first, then extinction.  By 2006, Martin had learned more.  He wrote, “I argue that virtually all extinctions of wild animals in the last 50,000 years were anthropogenic.”  Yikes!  The indigenous white folks of Europe had done it too!

Evolution had fine-tuned us for living in tropical climates.  Many of the new lands we wandered into had uncomfortably chilly non-tropical climates.  We were forced to develop innovative solutions, like needles, awls, sewn clothing, and protective shelters. 

When we arrived in new regions, the wildlife was clueless.  Mysterious bipedal primates did not trigger danger alarms, because we didn’t fit the standard predator template.  “We were a brilliant new predator with sophisticated weapons, dogs, and fire.”  For a while, hunters enjoyed the pursuit of fearless prey, many of whom became victims of fatal tameness, like dodos.  During the Lewis & Clark expedition, Clark once bayoneted a wolf that calmly walked past.

Hunting focused on jumbo sized animals that didn’t breed like bunnies, or zoom like gazelles.  Small groups of humans roamed across vast roadless wilderness on foot, armed with Stone Age weapons.  Game was depleted over the course of centuries, and the process of decline could have been imperceptible to living generations.  As game got scarce, the diaspora advanced into new regions.

Everywhere we migrated, the megafauna had evolved large strong bodies, a traditional defense against fierce predators, like sabertooth cats.  Unfortunately, when the predators were bloodthirsty primates from outer space, jumbo size was a vulnerability, and high speed escape was not an option.  The big guys could be killed with primitive spears.

America was the last major stop of the human diaspora, which had begun maybe 35,000 years earlier.  During this long process, pioneers had become highly skilled survivalists.  When the Beringia land bridge emerged from the sea, they advanced from Siberia into the “American Serengeti.”

I was shocked to realize the very long time spans of evolutionary history prior to human arrival.  The camel family in North America blinked out 10,000 years ago, ending a 40 million year residence.  Horses went extinct 9,000 years ago, after enjoying four million years here.  Mammoths wandered in from the Old World 1.5 million years ago.  It’s heartbreaking to comprehend the impact of the blitzkrieg.

IMPORTANT!  So, a number of species blinked out.  When the American megafauna extinction surge wound down, what came next was 10,000 years (100 centuries) of relative stability, according to Flores.  The human pioneers remained, and eventually coevolved with the species that survived.  This preserved the continent’s downsized wildlife community.  Humans learned ecosystem limits, established wise taboos to avoid overhunting, and nurtured a culture of profound respect and reverence for the entire family of life. 

Species that survived extinction now had less competition.  With the giant bison gone forever, the much smaller bison we know today exploded in number.  They reached reproductive age faster, and successfully coevolved with the remaining survivors.  

Sadly, the 100 centuries of stability zoomed off a cliff 500 years ago, when visitors from the Old World began washing up on the Atlantic coast — something like a bloody asteroid strike.  The aliens brought with them an assortment of deadly infectious diseases for which natives had zero immunity.  There were maybe four million natives in 1492.  Epidemics rapidly spread westward, killing about 90 percent of them within 100 years. 

This die-off sharply reduced hunting pressure on the wildlife, which was free to grow explosively.  In 1585, Thomas Hariot was astonished by the fantastic abundance of animals he saw in Virginia.  It was an Eden created by disease.  Settlers were free to hunt like crazy in a wilderness where there were no rules or regulations. 

In addition to diseases, colonists also imported their infectious worldview.  Their religion had roots in a herding society that treasured enslaved livestock, and detested predators.  Their Old World culture was built on a foundation of human supremacy, domestication, civilization, manufacturing, fanaticism, patriarchy, environmental devastation, and pathological self-interest. 

From time to time, Flores stopped to take a long hard piss on the notion of self-interest, a demonic quirk in the settler’s worldview.  I suspect it emerged with the rise of farming, herding, personal property, and individual salvation.  Its one all-consuming question has been “how can I get what I want?”  We suffer from an insatiable lifelong pursuit of social status, to the fullest extent possible, by any means necessary.  Nothing else matters.  Sorry kids!  Sorry wolves!

The traditional worldview of most tribal cultures majored in cooperation instead.  It nurtured mindfulness, and profound reverence for the family of life, the mother of their existence.  They were something like the folks who made the passionate cave paintings at Chauvet.  With few exceptions, the named gods of Native Americans were animals — coyote, raven, rabbit, etc. 

In the Old World religion, humans were very special critters, the other animals were not.  By and by, settlers from the Old World flooded into America.  They had domesticated animals and religions and economic ideas wherein “animals were not kin but resources.”  Their lives had no sacred significance.  So, the more hides, pelts, and furs you could take to market, the more cool stuff you could get.  Yippee!

Native folks thoroughly detested the monstrous colonists, but were fascinated by the unusual stuff they had.  Fifty deerskins could be traded for a metal pot.  Hatchets, axes, and knives were more expensive.  Whiskey was intoxicating.  The desire for this stuff was powerful, but it wasn’t free.

It was in the self-interest of the market, and the colonies, to leave nothing of monetary value unmolested.  Wild animals were pests that stood in the path of progress, and their extermination would continue until it was no longer profitable.  For natives, all options sucked.  They struggled to do their best.

In 1972, I was a roller coaster operator.  Riders slowly went up the steep hill, and then rapidly zoomed downhill screaming their brains out.  Flores provides readers a similar experience.  Most of his book describes the terrifying mass insanity that ravaged America in the last 500 years.  Readers will scream their brains out as they plunge deep into the cesspool of Big History, our horrifying monster closet.

Flores wrote that the invaders forced “a transformation of a hundred centuries of Native America into a re-creation of Old World civilization on a new continent.”  Five centuries ago, Old World folks and animals arrived, “and then, like some new contagion spreading inland from the coasts, proceeded to effect a widespread demolition of almost all that was here.”

In one year, 1743, the port at La Rochelle, France “took in 127,000 beaver pelts, 30,300 marten furs, 12,400 river otter furs, 110,000 raccoon pelts, along with its big haul for that year, the stripped skins of 16,500 American black bears.”

“In 1874 Bozeman market hunters were hip-deep in the big bonanza.  That year they shipped out 48 tons of elk skins, 42 tons of deerskins, 17 tons of pronghorn skins, and 760 pounds of bighorn skins.”

“Governments at all levels paid money for the heads or ears or scalps of a suite of animals — wolves, coyotes, mountain lions, grizzly and black bears, jaguars, bobcats, lynx — for the single purpose of promoting agricultural economies.”  Dead animals (or meat chunks) injected with strychnine were put everywhere to poison scavengers — wolves, coyotes, eagles, vultures, ravens, magpies, foxes, skunks.  It was sold in bulk in every store.

To delight ranchers, Montana put out 3,567,000 poison baits to kill predators.  Between 1883 and 1928 Montana shelled out payments on 111,545 wolves and 886,367 coyotes.  In one year, a wolf killer earned enough to buy a ranch and livestock.

Passenger pigeons, had been in America for 15 million years.  My father was in diapers when the last one died in 1914.  “The largest nesting site ever reported, near Sparta, Wisconsin, in 1871, spread across 850 square miles (2,200 km2).”  One flock was estimated to have 3.7 billion birds. 

Life on Earth is powered by energy.  Sunbeams feed the plants, and plants feed the critters.  Agriculture and herding amplified the energy flow for humans.  More recently, the flow has been explosively accelerated by burning fossil hydrocarbons, which are not limitless or harmless.  We can now temporarily feed more than eight billion.  We’re heating the planet into a toasty concentration camp crematory.  The machine’s guiding force is insanely clever childish self-interest, which is dumber than dog shit, but far more powerful than foresight, wisdom, cooperation, and mindful self-control.  SCREAM!!!

Wild Free and Happy Sample 37


[Note: This is the thirty-seventh sample from my rough draft of a far from finished new book, Wild, Free, & Happy.  I don’t plan on reviewing more books for a while.  My blog is home to reviews of 203 books, and you are very welcome to explore them.  The Search field on the right side will find words in the full contents of all rants and reviews, if you are interested in specific authors, titles, or subjects.] 

Potato

Two super foods were domesticated in the New World, potatoes and corn.  It’s possible to grow both without draft animals and plows.  Both plants produce more calories per acre than any Old World crop plant, except for rice, an Asian super food.  Super foods possess especially powerful juju for accelerating the growth and collapse of dense and self-destructive populations. 

Potatoes (affectionately nicknamed “spuds”) can be grown in a wide variety of soils and climates, at elevations ranging from sea level up to 14,000 feet (4,267 m).  Spuds originated in the Andes region of western South America.  They are now grown in at least 149 countries.  There are still many varieties of wild potatoes in the Andes, and they come in every size, shape, and color.  The tubers of some varieties contain bitter toxins, which encourage hungry critters to eat other stuff.  Spuds are smarter than they look.

It’s unclear when they were first domesticated, but it was certainly prior to 2000 B.C.  There are maybe 400 types of domesticated spuds.  Prudent farmers might plant 50 to 60 varieties in their fields, because something that kills one is less likely to kill all.  Spuds are awesome.  The plants mature rapidly, in just 90 to 120 days.  Per day, they produce more food energy per acre than any other crop plant.  An acre of potatoes produces up to four times more calories than an acre of grain.

John Reader noted that potatoes are an especially nutritious plant food.  Compared to cereal grains, spuds provide a better mix of carbs, protein, vitamins, and minerals.  The carbs are primarily starch, which is released into the body more gently than carbs from fats or sugars.  Spuds are a good source of B vitamins, and deliver lots of vitamin C.  Grains have more protein, but spuds provide protein of higher quality, including essential amino acids that the body must acquire readymade. 

Reader says that, of all foods, potatoes provide the “best all-round package of nutrition.”  In Ireland 200 years ago, adult males consumed an average of 10 pounds (4.5 kg) per day.  With a glass of milk with every meal, they would get 4,000 calories per day, and receive all the required nutrients.  At times of hard labor, lads would sometimes eat up to 20 pounds per day.  While Irish peasants were often dirt poor, dressed in rags, and living in mud huts, they had a healthier diet than most Europeans.  Unfortunately, being well nourished enabled higher birthrates.  Population soared almost 500 percent in 154 years (1687 to 1841).  Danger!

Inca Empire

Spuds are associated with the Inca (Inka) civilization, whose capital was Cuzco (Cusco), Peru.  The founders were the Quechua people, who were hunter-gatherers long before they became farmers.  Hunter-gatherer cultures were living in Andes by 12,000 years ago, and they were the ones who eventually domesticated potatoes. 

The Inca civilization was sort of a flash in the pan, existing from about 1438 to 1533, until snuffed out by Spaniards, and their diseases (smallpox, influenza, typhus, measles).  Preceding the Incas, there were a number of civilizations that rose and fell in the Andes region over the span of several thousand years.  The Inca Empire had a population of maybe 6 to 14 million, overseen by an elite class of 15 to 40 thousand.  The elites were not universally loved, and many folks celebrated the arrival of the tyrannical Spanish, which they saw as a great liberation from unbearable oppression. 

The Inca Empire was 2,200 miles long (3,540 km), and 190 miles (306 km) wide.  Prior to the tsunami of Europeans and their slaves, the Incas were the largest empire that ever existed in North and South America.  They were home to 40 percent of the combined population of both continents.  The range of the empire was essentially limited to habitat that was suitable for llamas and alpacas, extremely important animals that provided meat, manure, hides, and fiber.  The Incas had no wheels, no writing, no iron or steel, no riding animals, and no draft animals to pull carts or plows — but llamas were used to haul loads of stuff.

The Incas grew food on terraced plots, and built irrigation systems.  They built stone cities and temples, cut tunnels through mountains, crossed rivers with rope suspension bridges hung from stone towers.  They built causeways across wetlands, and cut pathways along the sides of steep slopes.  They had 14,300 miles (23,000 km) of paved roads, long enough to encircle the globe.  Teams of relay runners could carry messages 1,491 miles (2400 km) in five days.  Great roads also accelerated the spread of diseases, Spaniards, and missionaries.

The original staple food for folks in the high Andes was potatoes, which were often grown in rotation with quinoa and kañihua (cañihua) — two plants that produce high protein cereal-like seeds, but neither are technically cereals, because they aren’t card-carrying members of the grass family.  The seeds of both can germinate at or near freezing temperature. 

Plots of cropland were periodically fallowed, and herds of llamas and alpacas were moved in to drop steaming gifts of precious fertilizer all over the place.  In season, folks dined on fresh spuds.  Surplus spuds were freeze dried into chuño, a nutritious commodity that the tax collectors came to collect.  Chuño could be stored for years.  Archaeologists at one site found chuño created 2,200 years ago.

Chuño can be made at elevations above 13,000 feet (4,000 m) during the long dry season, when there are freezing temperatures at night, and bright sunlight in the daytime hours.  Chuño country is not far from the equator, but high elevations create an unusual combination of “tropical noon and arctic midnight,” which is perfect for freeze drying. 

The process for making chuño could take two months.  It involved freezing, soaking in cold water, freezing again, rubbing, squeezing, and drying in direct sunlight.  The complicated process removed the water, skins, and toxins.  The end product was light, firm, highly nutritious, and chalk-white.  Incas also freeze dried the flesh of birds, fish, alpacas, and llamas.  The word “jerky” came to us from the Andes.

Civilizations cannot exist for long if they don’t have effective systems for storing substantial quantities of food (usually grain) to keep folks fed during lean seasons, lean years, and wartime.  In the Old World, the emergence of agriculture and pottery-making were closely associated.  When dried grain was stored in sealed ceramic containers, it was not lost to rats and mice.

Incas stored chuño, jerky, and corn in thousands of frosty underground warehouses scattered throughout their empire.  Stored food provided abundant fuel for the rapid expansion of their empire — road building, urban construction, military adventures, and so on.  It also provided a social safety net.  Some say that Incas never starved.  Fifteen years after defeating the Incas, one Spaniard commented that food stored near Xauxa enabled him to feed 2,000 troops for seven weeks. 

At some point prior to the Inca era, corn from Mesoamerica arrived in the Andes.  Corn produced high yields, was suitable for long term storage, did not require labor-intense freeze drying, and was easy to transport (but nutritionally inferior to spuds).  Corn cannot be grown at elevations above 8,200 feet (2,500 m).  Where it could be grown, folks grew corn instead of spuds.  Inca leaders actively encouraged the intensified production of corn, and John Reader called this decision a “masterstroke.”  Folks had to build new terraces and irrigation systems to grow more corn.  Potatoes remained the most important crop, but the decision to deliberately maximize the output of super foods lit the fuse for the explosive growth of the Inca Empire.

So, once the Inca leaders were defeated and out of the way, the kind and loving Spaniards shape shifted into cruel, greedy, demonic monsters.  They snatched all the awesome gold and silver treasures in Cuzco, melted them down, and shipped eleven tons of it back home.  Then, they learned about the Potosí silver mine, assembled lots of forced labor, and created a boom town.  In the year 1592, Potosí produced more than 400 tons of refined silver.  By and by, back in Spain, this tsunami of wealth blindsided an already wobbly economy with soaring price inflation.  It also funded the creation of the Spanish Empire.  The royalty, giddy with enormous wealth, decided this was a good time to go on the warpath. 

In addition to gold and silver, lots of other stuff was sent back to the Old World, including turkeys, guinea pigs, cocoa, and tobacco.  A planet-rocking time bomb was also shipped back home — two super foods: spuds and corn.

Super Foods Supercharge Europe

Clive Ponting noted that until about 1800, most of the world’s great cities were outside of Europe.  In the year 600, Rome was home to 50,000, while 100,000 lived in Teotihuacán in Mexico.  Of the 100 towns and cities in Europe in 1000, half were in Italy.  In 1086, London had a population of just 10,000.  The staple foods in Europe were cereal grains, which produced far fewer calories per acre than spuds, were far less nutritious, and far more laborious to plant.  Corn and spuds could be planted with simple hand tools and human muscle power.  Wheat, rye, barley, and oats grew best in soil that was pulverized by harnessing a plow to oxen or horses — a far more resource-intensive process.

Spuds arrived in Spain by 1570, and gradually migrated across the continent, arriving in Scandinavia 100 years later.  The adaptation of corn also spread slowly.  Dirt poor subsistence farmers, who constantly felt the cold breath of starvation on their backs, were exceedingly conservative.  They were never eager to impulsively throw all caution to the wind, and bet their survival on weird exotic crops from outer space.

Alfred Crosby noted that skeptical farmers were eventually convinced that the exotics were better in many ways than the crops they traditionally grew.  Over time, corn became a staple in southern Europe.  Potatoes were widely adopted in northern Europe, where they produced far more nutrients per acre than traditional grain crops.  It took 5 acres (2 ha) of grain to feed a family of five, but just 1.5 acres of potatoes.  Farmers could raise potatoes on marginal soils, using only a spade.  Unlike grains, spuds needed no grinding or milling.  Like grains, potatoes were also vulnerable to molds, fungus, and weather that was too wet or cool.  Western Europe was best suited for growing healthy forests and wildlife, rather than spuds, cereals, livestock, and tropical primates.

Grain could be stored for years, but not spuds.  Europe’s climate was unsuitable for making freeze dried chuño.  Western Europe had mild winters during which the ground rarely froze.  Spuds could be left buried in the field for several months, unharmed by light frost, until springtime warmth returned. 

Spuds provided some extra security for farm families.  When grain is ripe, it has to be harvested and stored.  William McNeill noted that full granaries were treasure chests of essential nutrients, which made them primary targets for annoying visitors, like tax and rent collectors.  Collectors grabbed the grain, but left the spuds alone, because they were too much work to dig up, and they couldn’t be stored indefinitely.  Landlords and nobles wanted grain.

Passing troops were even more despised than the collectors.  In the old days, armies did not haul around caravans of food supplies.  Instead, they stopped at farms, confiscated their stored grain, and left the peasants to starve.  This was a common practice, and more than a little discourteous.  In wartime, while soldiers were dying on the battlefield, peasants were dying in their huts, which seriously disrupted the stability of food producing rural communities.  How smart was that?

During the War of Austrian Succession (1740-48), Fredrick the Great was astonished to discover that far more spud growing peasants survived, compared to those who grew grain, lost it, and starved.  Like the tax and rent collectors, passing troops didn’t have the time or desire to dig up fields of potatoes.  It was much faster and easier to empty the granaries and march on.  Fredrick realized that if folks planted more spuds, wartime would be less devastating to society.  It was wise to be nice to peasants.  So, he distributed free seed potatoes throughout his kingdom. 

McNeill noted that others soon joined the parade.  Leaders in Austria, Russia, and France recognized the strategic advantages of joining the spud cult.  Over time, the resistance of conservative peasants melted away.  More and more came to the conclusion that they preferred boiled potatoes to death by starvation. 

This inspired a wave of innovation in agricultural practices.  Traditional processes were fine-tuned for maximizing grain output.  New and improved processes were needed to accelerate spud production, and clever folks came up with some bright ideas.  In the traditional system, every year either a third or half of the cropland was left fallow, to suppress weeds.  In the new system, fallow land became potato fields.  Amazingly, the amount of grain harvested was not diminished, and spud harvests provided a mother lode of bonus calories. 

Before long, bonus bambinos were squirting out of wombs, at just the right time.  See, turning fallow land into potato fields required additional labor, because happy weeds now had to be mercilessly killed, in late spring and early summer, by workers with hoes and spades.  By utilizing this extra labor, farmers could now produce two to four times more calories per acre, and feed even more bambinos.

McNeill’s big idea was that potatoes radically changed world history during the era spanning from 1750 to 1950.  Spuds had become popular in Ireland and the Scottish highlands, but were especially important on the vast European plain, which spanned from northern France, Germany, Poland, and eastward into Russia. 

While spuds required more farm labor, skyrocketing population growth provided more workers than needed in the fields.  Surplus people provided a labor force for the Industrial Revolution, which developed rapidly in northern Europe.  Low wages and miserable working conditions were more desirable than starvation.  The transition to fossil energy turbocharged the boom years.  The era of 1750 to 1950 was also a time when Europe established colonies and built empires.  McNeill noted that the entire world was rapidly and radically transformed.  Then, around 1947, European empires began disintegrating, and a new era began.

He wrote that without potatoes, Germany would have never grown into a leading military and industrial power in Europe after 1848.  Russia would not have become a major threat to Germany after 1891.  Millions of Europeans would not have migrated to America and other regions.  And so, the humble dirty spud triggered an avalanche of chaotic bad craziness that blindsided societies all around the world.

Alfred Crosby wrote that, aided by potatoes and corn, both Europe and America were able to harvest far more food.  People were better nourished, so child mortality dropped.  The population of Europe leaped from 80 million in 1492, to 180 million in 1800, 390 million in 1900, and 556 million in 2019.  Europe was bursting with people, and many migrated to colonies — Australia, New Zealand, southern Brazil, Uruguay, Argentina, Canada, and the U.S.  Bottom line, world population leaped from 450 million in 1500 to 7.8 billion in 2020.  Crosby concluded, “Calories can make as much history as cannons — more in the long run.”

Monocultures Beg For Trouble

Jeffrey Lockwood studied locusts.  He described a swarm that visited Plattsmouth, Nebraska in June 1875.  It was 110 miles (177 km) long, up to a mile (1.6 km) high, and travelled at 15 miles per hour (24 km/h).  They visited for ten days, and covered maybe 198,000 square miles (512,817 km2).  This swarm may have included 3.5 trillion locusts, and there were many other hungry swarms.

Where the swarms touched down, they devoured the greenery.  They voraciously ate the clothing off of the clueless settlers, who had not majored in environmental history.  In a few hours, a field could be rubbished.  To express their deep gratitude to the settlers, for so generously providing such a wonderful banquet, the departing swarm might leave behind 940 million eggs per acre.

The ambitious American settlers suffered from get rich quick fever.  In an era of above average precipitation, they plowed up large regions of western plains and planted wheat.  Unmolested plains ecosystems are home to a highly diverse mix of species.  Big Mama Nature cherishes diversity, and detests manmade monocultures (spit!).  It turns out that wheat was a grass that locusts considered to be the most delicious food of all, and wheat was the primary crop on the western plains.  Locusts were far less interested in gobbling up grazing land or dairy pastures.

Wheat was first domesticated in the Fertile Crescent of the Middle East, homeland of the Judeo-Christian culture.  Wheat thrived in the Mediterranean climate, which provided generous winter rains to germinate the thirsty seeds.  The Bible mentions locusts 28 times.  Richard Manning once said, “The domestication of wheat was humankind’s greatest mistake.”  (Or, was it corn, or potatoes, or rice, or…?)

As I bike around my town, I often see pennies lying on the street.  For most folks, the low value of a penny simply does not provide sufficient motivation to stop, bend over, pick it up, and take it to the bank.  This is something like a healthy diverse ecosystem — the things that critters value are widely scattered.  Now, compare that to a monoculture.  Let’s dump a sack of $100 bills on the street, a dense concentration of value.  This treasure promptly attracts a large excited swarm and is rapidly swept away.  Right?

Similarly, infectious diseases are far more likely to create epidemics in large, densely populated cities, with poor sanitation, and lots of malnourished people — especially societies that are interconnected with complex networks of long distance trade and travel.  This is a highly vulnerable combo — a dense monoculture of people, plus high mobility ($100 bills).  It’s much safer to live in small, remote, isolated villages that have clean water, adequate nutrition, and little or no contact with the outside world (pennies).

Like the wheat and locust duet, it’s a similar story with other crop plants.  Unnatural density is begs for trouble.  James Scott wrote that both humans and crops are vulnerable to viral, fungal, and bacterial diseases.  Crops can be damaged by snails, slugs, insects, birds, rodents, and other mammals.  Weeds can diminish their access to sunlight, water, nutrients, and space.  A serious vulnerability for civilizations is that their survival depends on a successful annual harvest of just one or two staple foods.  Over the centuries, many have gotten blindsided by droughts, deluges, floods, fires, pests, frosts, storms, crop diseases, and mean enemies.

Hunter-gatherers were more like the pennies scenario, low density people, in isolated groups, who obtained their nutrients from widely scattered local sources — healthy diversity, not goofy sprawling monocultures.  Wild folks could live perfectly well by looking for pennies, because they couldn’t imagine something as ridiculous and unbearable as living in mobs of weird smelly strangers and pursuing an obscenely wasteful $100 lifestyle.

And now, an important story.  John Reader was impressed by how nomadic foragers benefitted from their time-proven ultraconservative way of life.  Some plant and animal foods were regularly eaten.  Others were deliberately set aside to be famine food.  Some groups also reserved portions of their land as a safety net that was only used in lean periods.

In the 1960s, anthropologists in Botswana were astounded to observe how well the San people lived during the third year of an extreme drought in the Kalahari, one of the harshest ecosystems on Earth.  Neighboring Bantu farmers were hammered by three consecutive crop failures, and 250,000 of their cattle died.  United Nations famine relief kept 180,000 farming people on life support.  Some farmers who didn’t get food relief had to forage for wild food, putting further strain on food resources.  Still, the San were able to acquire their food with just 12 to 19 hours a week of effort.  They dwelt in a desolate “wasteland” that no civilized people could survive in, and they lived well and joyfully. 

And so, dear reader, please remember this snapshot of ultraconservative wild survival, because it is strikingly different from stuff on the following pages about crop failures, blights, famines, and so on — the life threatening vulnerabilities of being completely dependent on the ups and downs of a small number of domesticated food plants.

Clive Ponting wrote an incredible information packed book on environmental history.  Most readers have never felt the gnawing hunger of living during an extended food shortage.  We have no memories of the “good old days” of wholesome, low-impact, horse powered, organic agriculture.  Ponting summed it up like this: “Since the rise of settled societies some ten thousand years ago the overwhelming majority of the world’s population has lived in conditions of grinding poverty.”  He added, “Until about the last two centuries in every part of the world nearly everyone lived on the edge of starvation.” 

In the old days, “All but about five percent of the people in the world were peasants, directly dependent on the land and living a life characterized by high infant mortality, low life expectancy and chronic undernourishment, and with the ever-present threat of famine and the outbreak of virulent epidemics.”

Ponting’s perception of the past is very different our culture’s romanticized version, which presents us with stuff like the paintings of happy dancing peasants by Pieter Breughel.  Having read loads of environmental history, I know that Ponting was not a creep who invented fake history.  The era of muscle powered agriculture indeed gave the planet and its critters a painful beating.  Of course, today’s fossil fuel powered nightmare has enabled us to beat the planet even faster and harder, in ways never before believed to be possible.

Potato Blight

John Reader wrote that spuds first arrived in Ireland between 1586 and 1603.  At that time, its population was somewhere between 1 and 1.5 million.  By 1845, when the blight began, it had soared to 8.5 million, and the survival of about 90 percent of them depended almost entirely on potatoes.  Well-nourished peasants had higher birth rates, and stronger resistance to disease.  But when the blight nuked the spuds, a million peasants, weakened by hunger and disease, stood in long lines to take selfies with the Grim Reaper.

Because Ireland had a wetter climate, it was not an ideal place to grow cereals.  Spuds could often tolerate dampness that would rot oats.  So, potatoes were less risky, produced lots of calories, and didn’t require a draft animal and a plow.  Ireland was the first nation in northern Europe to largely switch from cereal crops to spuds. 

Before long, the exotic tubers were popular everywhere, from the palace to the pigsty.  Brian Fagan noted that the population explosion had been fueled by several varieties of outstanding, gourmet spuds, like the Black, Apple, and Cups.  But the production of these types could not keep up with the growing numbers of spud addicts.  Feeding large families on small plots of land inspired a determined search for varieties of spuds that were even more productive.

By 1835, the Lumper, or horse potato, won the competition and became the dominant spud on the Emerald Isle.  It came from England, where it had been developed for use as livestock fodder.  The remarkably unexciting Lumper was coarse and watery, less nutritious, more vulnerable to disease, but indispensable life support for dirt poor peasants who had way too many kids.  On the plus side, Reader said that the Lumper was 20 to 30 percent more productive than the fancy upper class spuds it replaced.  On the downside, every single Lumper in every single field was an exact genetic clone (imagine a world with 7.8 billion Donald Trumps).  What could possibly go wrong?

The famous Irish famine of 1845 was, in some ways, no surprise to anyone.  Back in the good old days, crop failures, famines, and epidemics were commonplace.  For example, Clive Ponting wrote that between the tenth and eighteenth centuries, France had 89 famines that were widespread national disasters, of which 26 of them hit in just the eleventh century.  England suffered numerous local famines in the sixteenth and seventeenth centuries.  Famine rocked all of Europe from 1594 to 1597.  Famine struck Belgium and Finland in 1867 and 1868.  Rinderpest zoomed into Europe from Russia, where it killed 1.5 million cattle from 1709 to 1714.  And so on.

Anyway, long before the late blight fungus arrived in Ireland, crop failures in 1740 and 1741 killed 400,000 Irish people.  The late blight didn’t arrive until 1845.  John Reader mentioned a theory that the late blight fungus originally emerged in the highlands of central Mexico.  By and by, it migrated to South America.  From there, in about 1841 or 1842, it hitched a ride with a shipment of potatoes to the United States.  In 1843 the first outbreak of blight appeared in New York and Pennsylvania, and then spread along the east coast.  Two years later, in 1845, it had spread west to the Mississippi, and north into Canada. 

Meanwhile, in 1843, farmers in Flanders and Belgium were suffering losses from viral diseases and dry rot.  To cure the problem, they ordered what they thought were healthy seed potatoes from the U.S. (where the blight was raging).  Oh-oh!  In the winter of 1843-44, the late blight fungus crossed the Atlantic in a load of spuds.  Transatlantic trade in potatoes was made possible by new and amazing high-speed steam ships, and by the use of ice to prevent spoilage.  Previously, sailing ships were too slow to deliver a load of spuds in good condition. 

It’s interesting to note that sailing ships were also too slow to deliver live cholera microbes to the New World.  But then, in 1832, a speedy new steamship from Britain was able to zoom across the ocean, and deliver cholera to a population in Montreal that had zero immunity.  Before long, many were surprised when they erupted with firehose diarrhea.  From there, the disease spread like lightning across the New World.  Once again, millions took selfies with the Grim Reaper.

I need to pause for a second here to emphasize an important notion: there’s no place like home.  During the maybe three million years when our wild ancestors lived in a low impact manner, they dined entirely on local wild foods.  They naturally spent their lives in the region where they were born, because they were not migratory critters like geese, storks, or butterflies.  They never forgot the creator’s instructions on how to live like tropical primates, which is why they lived very well for a very long time.  They didn’t invent cars, planes, and other goofy stuff.  Every day, they simply walked to work — perfectly sustainable transportation.

Spuds evolved in the Andes, where they adapted very well to a unique high elevation ecosystem, and enjoyed happy and fulfilling lives.  In recent centuries, travelling tropical primates, who were far from their homeland, discovered spuds, and eventually carried them to distant lands that were less ideal than the Andes.  When planted in Europe, they triggered a scenario similar to the “bull in a china shop” proverb.  Prior to farmers, about 95 percent of west and central Europe was a healthy happy paradise of primordial forests.  This harmonious situation was not in any way improved by deforestation, spud addiction, and huge swarms of tropical primates with voracious appetites.

Richard Manning noted that when spuds are planted in regions outside their Andes homeland, they can be far more vulnerable to insects, fungi, and viruses.  Apparently the late blight fungus is widely dispersed, and usually dormant.  Its wakeup alarm goes off when the weather gets too damp or chilly.  Writing in 2000, Manning noted that in upstate New York, a 100 pound sack of ordinary spuds could be bought for $6, but organic spuds would cost $30.  The difference is because no other food crop is blasted with so many pesticides, in order to zap insects and fungi. 

In Brazil, some regions get sprayed 30 times during the growing season.  Also, unlike cereal grains, potato seeds are living tissue that can transfer disease from this year’s crop to next year’s.  So seeds also get blasted.  (Potato seeds are chunks of tubers grown last year.  Each chunk must have an “eye” on its skin, a potential embryo for a new plant.)

Sorry!  Back to the blight.  The summer of 1845 was a cool and wet one.  Blight struck Ireland, and parts of Belgium, France, and the Netherlands.  Then it spread to Demark, Wales, Scotland, northern Italy, southern Norway and Sweden.  Four months later, 772,204 square miles (2 million km2) of fields were ruined.  It was a memorable and heartbreaking experience.

Cecil Woodham-Smith wrote about the Irish famine.  The 1841 census revealed that Ireland was probably the most densely populated region in Europe, thanks to spuds.  The census noted that half of the people resided in rather unpretentious affordable housing units — small, windowless, single room, mud cabins.  In 1845, the fields were looking fine and healthy — until three weeks of wet and cool weather spoiled the party.  The crop failure was partial.  Fields of cereal crops were not harmed.

In 1846, the blight was severe, and the harvest of both spuds and grain was a poor one.  They weren’t going to have enough seed potatoes to plant all the fields in the spring of 1847.  Across much of Europe, the 1846 harvest was a total or partial failure.  Black fields stretched for hundreds of miles, and the stench of rot was overwhelming.  By September, not even folks with money could acquire food.  They ate cabbage leaves and blackberries.

Across Europe, the winter of 1846-47 was extremely long and severe.  The Thames was jammed with floating ice.  By January, the Irish folks in county Mayo looked like skeletons.  The sheep, cattle, poultry, and dogs were gone.  The one remaining pig would not be long for this world.  The blight in 1847 was light, but the planted acreage was just 20 percent of normal, for lack of seeds.

In 1848, all the land got planted, and the people were giddy with hope that their troubles were over.  Things looked awesome, until the middle of June, when the wet weather would not stop.  The blight was severe.  In July, some fields would turn black overnight, and millions of ripe spuds rotted in the ground.  Even spuds stored away before the blight rotted.  Cereal crops were also damaged by heavy rains.  There was little to harvest.

In the end maybe a million emigrated, and a million died.  Woodham-Smith noted that mortality records were incomplete.  She estimated that for every person who died of starvation, ten died from disease.  The most popular pathogens were two types of “famine fever” — typhus and relapsing fever, both were spread by lice, and both were quite unpleasant.  A bit less popular was dysentery, which was caused by contact with fecal borne pathogens.

Farmers rarely if ever have a plan B when their crops fail, or their granary is swiped.  Their leaders may or may not come to their rescue.  The Irish didn’t get much help.  Earlier in this chapter, we looked at the San people of Botswana who easily survived a three year drought.  Not being chained to one piece of land, and not being heavily addicted to monoculture crops, allows more options for survival — and a healthier, more enjoyable life.

Wild Free and Happy Sample 20


[Note: This is the twentieth sample from my rough draft of a far from finished new book, Wild, Free, & Happy.  I don’t plan on reviewing more books for a while.  My blog is home to reviews of 201 books, and you are very welcome to explore them.  The Search field on the right side will find words in the full contents of all rants and reviews, if you are interested in specific authors, titles, or subjects.] 

Imperceptible Overkill

It’s easy to become perplexed when contemplating the megafauna extinctions.  Paul Martin described the process in North America as a blitzkrieg, an ecological catastrophe that was largely accomplished in a mere thousand years or so — far faster than the earlier extinction spasms in the Old World.

Obviously, the North American spasm was only lightning fast in an evolutionary timeframe.  From the perspective of living humans, a thousand years is quite a while.  I expect that some of my readers are younger than 200.  A much earlier spasm in Africa took place over hundreds of thousands of years.  These hominin ancestors were apparently still cadets in their ability to hunt slightly too hard.

All animals pay careful attention to the here and now, in the immediate vicinity.  Few, if any, think about tomorrow or next year.  Wild ecosystems, and the weather, exist in a state of constant change.  It’s impossible to predict what living conditions will be like a year from now, or in two months.  What game will be plentiful?  What will be scarce? 

Small isolated bands of people were living in a vast wilderness, unaware of current conditions in every surrounding hill and valley.  There was no way they could accurately monitor the populations of game animals.  When hunting was bad, they couldn’t know why.  Was the herd declining, or had they wandered elsewhere to visit relatives?  An ecosystem is not an enclosed laboratory where everything can be precisely measured and controlled.  Hunting is a game of chance.

Anthropologists have reported that some hunter-gatherer cultures, who survived into recent times, understood the risks of overhunting.  They developed rituals and taboos for avoiding it.  Richard Nelson wrote that when deer numbers declined, the Koyukon people stopped hunting them for several years, and ate other critters instead.  Also, when game was abundant, they would stop hunting in a portion of their domain, creating a refuge where game could get a break from hunting, and recharge their numbers.  Sometimes mindful efforts at conservation worked well.  Sometimes folks starved.  Humans were not in full control.

Two important factors in megafauna extinctions were shifting baseline syndrome, and the low reproductive rates of large game animals.  Shifting baseline syndrome describes the fact that our conception of “normal” is continuously changing.  Kids in school today can’t imagine a world without smart phones, video games, and access to unlimited sources of entertainment.  When I was born in 1952, there were five billion fewer humans on Earth.  In my childhood, the only glowing screen was a small black and white TV with four boring channels that shut down out at 11:00 P.M.  In those days, we kids regularly played together outdoors all the time, and communicated by actually speaking to each other, face to face.

“Normal” in 1960 was far different from normal in 1990, or 2020.  My perception of normal fishing is far more modest than my father’s, my grandfather’s, and so on.  Each generation experiences fewer and smaller fish, yet each considers the reality they experience to be the normal state.  Pleistocene hunters did not know how abundant game was in their grandfather’s days, or 500 years earlier.  Nobody probably noticed if the number of mammoths was gradually declining.

Fernando Fernandez concluded that the primary factor in megafauna extinctions was the fact that the jumbo-sized walking meatballs that hunters eagerly desired did not reproduce like bunnies or cockroaches.  Killing them just slightly above their fertility rate could wipe them out over the passage of centuries.  It wasn’t so much about the intensity of the hunting as the fragility of the hunted.  Over a thousand years, and many generations of hunters, extinctions may have been essentially invisible.

Elizabeth Kolbert noted that modern elephants do not reach sexual maturity until their late teens, each pregnancy takes 22 months, and there are never twins.  Because they reproduce so slowly, mammoths could have been driven to extinction by nothing more than modest levels of hunting.  Doug Peacock estimated that taking only 4 or 5 percent of a slow breeding species could put them on a gradual path to extinction.  Peter Ward estimated that if hunters had regularly taken just two percent of the mammoths each year, the extinction process would have taken 400 years — too slow for each generation of hunters to notice.  Hunting alone could have wiped them out.

Kolbert wondered how Neanderthals had lived in Europe for more than 100,000 years without causing weird disturbances.  She suspected that if humans had never arrived, the good old days of abundant megafauna would have never ended.  Prior to the arrival of skilled teams of human hunters, jumbo size provided a survival advantage.  Megafauna thrived in Eurasia and the Americas 50,000 years ago, before trouble rumbled in — at which point being huge and slow became a serious vulnerability.  Kolbert was not sure if there was ever a time when humans lived in ecological harmony.

Pita Kelekna wrote that large herds of wild horses were once common in the river valleys of western and central Europe.  By about 8,000 years ago, they were nearly eliminated by overhunting in most of the continent, except in a few small pockets.  Several writers concluded that domestication probably spared horses from extinction.  Folks learned that horses were more valuable for transportation, and as beasts of burden.  There were many other delicious critters to feast on.

Australasia

The Australian extinctions probably occurred between 50,000 and 40,000 years ago, following the arrival of humans.  Tim Flannery described how ecosystems went through a number of substantial changes, as the early Aborigines learned how to survive in an unusual land, via trial and error.  He believes that they finally learned how to live in relative balance by around 12,000 years ago. 

Australia was blessed with having ancient worn-out soils, and a bipolar climate.  Severe droughts could last years, which might suddenly end with terrific deluges.  Thus, Australia was a lousy location for the emergence of agriculture and civilization.  Aborigines retained a Stone Age way of life until 1788, when British colonists arrived, and attempted to transplant an English way of life to a land for which it was not ideal.

Humans arrived in New Zealand between 800 and 1,000 years ago, and by 400 years ago the moas were extinct.  Moas were ostrich-like birds that could grow to 10 feet (3 m) tall, and weigh 550 pounds (250 kg).  Many collections of moa bones have been found, some containing the remains of up to 90,000 birds.  Evidence suggests that a third of the meat was tossed away to rot.  Obviously, the birds were super-abundant and super-easy to kill.

In the global eco-catastrophe that we are experiencing today, Australasia did not historically play a leading role.  The planet-thrashing juggernaut, which was born in Africa, gained a lot of strength and momentum when humans migrated into snow country, where a challenging climate inspired a surge in techno innovation.

Europe

In Europe, the era of megafauna extinctions corresponded to the arrival of human colonists.  Most of the extinctions occurred in two spasms — from 45,000 to 20,000 years ago in the warmer south, and from 14,000 to 9,000 years ago in the cooler north.  The process was much faster than the earlier extinctions in Africa.  Two million years ago in Africa, our pre-human ancestors were smaller, and still learning the basics of big game hunting.  The humans who later colonized Europe were bigger, stronger, and better equipped for hunting.

Paul Martin had an intriguing notion.  In the tropics of Africa and Asia, the warm climate favored the existence of infectious diseases and parasites that tropical primates were vulnerable to, like sleeping sickness and malaria.  Maybe these pathogens limited the size of hominin populations, thereby boosting the survival of large game.  In the cooler climate of Europe, the pathogens that could harm humans were fewer in number or less virulent.  In snow country, maybe healthier humans lived longer and hunted more. 

Below is a sampler of some of the species that blinked out in Europe.  Most had been around for more than a million years, and had survived multiple ice ages.  This list is far from complete, and highly oversimplified.  These species had survived for a very long time, but their luck ran out following the arrival of humans.

Irish “elk” were actually a species of large deer (not elk).  They existed for several million years, including 400,000 years in Europe.  The last ones died 7,700 years ago in the Ural Mountains.  They lived throughout Europe, east to Siberia and China, and south to northern Africa.

Straight-tusked elephants were in Europe by around 780,000 years ago, and vanished 30,000 years ago.

Cave hyenas were gone by 13,000 years ago, after 3.5 million years.  They dined primarily on horses, steppe wisent, and woolly rhinoceros.  Large hyenas could weigh up to 225 pounds (102 kg).  They inhabited northern Africa, the Middle East, and much of Europe, and Asia.

Cave bears emerged about 1.2 million years ago, and vanished 29,500 years ago.  They ranged from Britain and Spain, east across much of Europe, and into Russia and Iran.

European cave lions were quite similar to the lions still alive in Africa.  The two lines diverged about 1.9 million years ago, and the European cats went extinct 13,000 years ago.  They ranged in a wide belt from Spain and southern England, to Siberia, Alaska, and the Yukon.

European hippopotamus ranged across Europe, from Spain to Britain to Greece.  They emerged 1.8 million years ago, and went extinct 24,000 years ago.

Woolly Mammoths emerged 400,000 years ago in Eurasia, and went extinct in Europe 10,000 years ago.

Woolly rhinoceroses were living on the Tibetan Plateau 3.6 million years ago.  They were common throughout Europe and northern Asia, from Spain to China.  They survived until 10,000 years ago.

Americas

Paul Martin created much controversy with his theory that many of the extinctions in North America took place within a thousand years.  Among his critics were Native Americans, who were offended by the implication that their ancient ancestors foolishly hunted too hard.  For them, Martin’s ideas had the stinky aroma of racism.  The dating of the fossil specimens found so far does not rubbish his theory.  He did acknowledge that the extinctions seem to have ended about 12,000 years ago, but by this time, all the remaining large species had probably learned, the hard way, that primates were dangerous predators.

In an attempt to sidestep accusations of racism, a number of experts have tried to shift the primary blame to climate change, but that theory does not hold up as well to scrutiny.  Efforts to place the blame on epidemic animal diseases have yet to discover supporting evidence.  In the last 50,000 years, there is a clear pattern that megafauna extinctions routinely followed the arrival of humans into new continents — not the ups and downs of glaciation cycles.

As humans crossed into North America from Siberia, hunting began in northwest Canada, and spread south and east like a wild fire.  Peter Ward wrote that within one to two thousand years, at least 33 genera (50 species) of large mammals went extinct — far more than in the preceding three million years, which included numerous glaciation cycles.  Many of those that disappeared had lived in America for tens of millions of years. 

To put the North American extinctions in context, let’s take a peek at some of the evidence. 

Elephant family species immigrated into America from 1 to 15 million years ago.  There were at least seven varieties (mammoths, mastodons, etc.).  They survived until 12,000 years ago.

Horses originated in North America about 4 million years ago, and later spread into South America, Asia, Europe, and Africa.  They were extinct in North and South America by 8,000 years ago.  The Equus genus includes horses, asses, and zebras. 

Saber-tooth cats emerged in Africa 12 million years ago.  Some types could grow up to 620 pounds (280 kg).  They have been found in North America, South America, Eurasia, and Africa.  They went extinct in Africa 1.4 million years ago.  In North America they vanished 10,000 years ago.

Scimitar-tooth cats emerged in Africa about 4 million years ago.  They vanished from Africa 1.5 million years ago, from Eurasia about 28,000 years ago, and from America about 12,000 years ago.

American lions originated in Africa over a million years ago, and migrated into North America, as far south as Central America.  They went extinct around 11,300 years ago.

Camels originated in North America maybe 40 million years ago.  By 2 to 5 million years ago, some had crossed into Asia, and spread into Africa.  In North America, they went extinct 10,000 years ago.  They still survive in the Old World.

Short-faced bears were among the largest land dwelling mammalian carnivores on Earth, and they were abundant in California.  The species emerged about 1.8 million years ago, and went extinct about 11,000 years ago.

Giant armadillos were mammals that originated in South America 5.3 million years ago, migrated into North America, and went extinct about 12,000 years ago.

Ground sloths could grow as large as elephants.  They emerged in North and South America about 4.9 million years ago, and went extinct 11,000 years ago.

Giant beavers were the largest North American rodent.  They emerged about 2.6 million years ago, and went extinct about 11,700 years ago.

Tapirs could grow up to 4.6 feet (1.4 m) long, and weigh up to 496 pounds (225 kg).  They emerged 20 to 30 million years ago in North America, and went extinct about 11,000 years ago in America.  In China, some survived until 4,000 years ago.

Woodland musk ox could grow to 934 pounds (423 kg).  They lived from Alaska to California, and east to New Jersey.  They emerged about 2 million years ago, and went extinct about 11,000 years ago.

Dire wolves lived in North and South America from 125,000 to 9,440 years ago.  The average wolf weighed about 150 pounds (68 kg).  Their prey included camels, bison, mastodons, ground sloths, and horses.
