Wild Free and Happy Sample 44 Update

 [Note: The following is a significant expansion of the Soil Destruction section of Sample 44.]

SOIL DESTRUCTION

Spencer Wells lamented the transition to food production, when folks shifted from foraging to farming and herding.  “Instead of being along for the ride, we climbed into the driver’s seat.”  Richard Manning agreed.  He said that in the good old days, “we didn’t grow food; food grew.”  Food production took an increasing toll on the soil.  Folks didn’t fully understand the consequences of what they were doing. 

In the good old days, wild ecosystems were complex communities of plants and animals.  These wild communities coevolved over time, which kept them fine-tuned for long term survival in ever changing local conditions.  Believe it or not, they could thrive, century after century, without irrigation systems, synthetic fertilizer, pesticides, fossil powered machinery, human stewards, and so on.

With the transition to plant and animal domestication, humans could produce greater quantities of food, and feed more mouths.  But the artificial ecosystems they created (cropland and pasture) commonly reduced natural biodiversity, encouraged erosion, and depleted soil fertility.

Walter Youngquist wrote that the average depth of the world’s topsoil is less than 12 inches (30 cm).  He added that almost all modern folks consider oil to be a vital strategic resource.  Oddly, far fewer have a profound appreciation for soil, the most precious mineral treasure of all.  For almost the entire human saga, our ancestors left fossil hydrocarbons in the ground, where they belong.  Soil is vital for the survival of the entire family of life — yesterday, today, and forever after.

He warned that, from a human timeframe, topsoil is a nonrenewable resource, because new topsoil is created over the passage of centuries, on a geological timeframe.  “Overall, one-third of the topsoil on U.S. cropland has been lost over the past 200 years.”  Humans are destroying it far faster than nature creates it. 

Youngquist mentioned the work of Peter Salonius, a soil scientist who performed 44 years of research.  Salonius came to the conclusion that all extractive agriculture, from ancient times to the present, is unsustainable.  Environmental history clearly supports his conclusion. 

Writing in 2000, J. R. McNeill wrote that the U.S. was currently losing 1.7 billion tons of topsoil per year to erosion.  At that time, there were 281 million Americans.  So, the loss would have been six tons per person.  Writing in 2007, David Montgomery noted that each year, the world was losing 24 billion tons of soil.  In 2015, Joel Bourne reported that every year, a million hectares (2.4 million acres) of world cropland are taken out of production because of erosion, desertification, or development. 

Richard Manning wrote, “There is no such thing as sustainable agriculture.  It does not exist.”  David Montgomery agreed.  “Continued for generations, till-based agriculture will strip soil right off the land as it did in ancient Europe and the Middle East.  With current agricultural technology though, we can do it a lot faster.”

Tobacco

Dale and Carter wrote a history of humankind’s war on soil.  Immigrants who colonized the U.S. behaved much like civilized colonists throughout history.  “They caused more waste and ruin in a shorter time than any people before them because they had more land to exploit and better equipment with which to exploit it.  Some ruined their land because they knew no better, and others destroyed out of greed for immediate profits, but most of them did it because it seemed the easiest thing to do.”

David Montgomery described the farmers of early America.  Tobacco was a goldmine, because it reaped six times more income than any other crop, and it could be shipped across the Atlantic and arrive in perfect condition. 

Growing tobacco was labor intensive, and slaves provided the muscle power.  It was also a heavy feeder on soil nutrients.  A farmer could make great money for three or four crops, after which the soil was severely depleted. 

At that point, they often abandoned the useless fields, and cleared forest to create new ones, for another round of jackpot moneymaking.  It was easier and more profitable.  In the early days, frontier land was abundant and cost little or nothing.

Back in Europe, it was foolish to greedily treat topsoil like a rape and run disposable resource.  Over time, agriculture had eventually collided with serious limits, when it was no longer easy to expand cropland area by exterminating forests.  So, respectful consideration was given to future generations of descendants, who wouldn’t enjoy inheriting a (%@&#!) wasteland.  Each generation deliberately made efforts to slow soil deterioration by regularly adding manure, compost, leaves, crushed bone, and other fertilizers.  Soil was treated like gold.

On the other hand, in early America, ambitious high achievers thought that being conservative stewards of the land was ridiculously stupid.  Livestock was needed to produce manure, and livestock required pasture.  Tobacco acres earned big money fast, and pasture acres did not.  Profit was their god word.

Cotton

Clive Ponting noted that a bit after the tobacco boom, the cotton gin made it more profitable to manufacture cotton fabric, rather than wool.  Cotton became a new goldmine for farmers and slave traders.  In Africa, slaves were often purchased by trading cotton cloth for them.  Like tobacco, cotton was very hard on the soil.  Compared to a food crop, it extracted 11 times the nitrogen, and 36 times the phosphorus.  Between 1815 and 1860, cotton was 50 percent of U.S. exports.

As with tobacco, depleted cotton fields were abandoned, and farm country migrated westward, as it devoured ancient forests.  It was cheaper, easier, and more profitable to move on, so they did.  David Montgomery described how these folks broke every cardinal rule of careful land stewardship.  Farmers did continuous planting without crop rotation, used little or no manure, and plowed straight up and down hills (not contour plowing). 

Highly explosive ignorance resulted in painful lessons and enduring destruction.  Stripping away the forests in hill country deleted what had held the soil in place for thousands of years.  Damage was extreme in the Piedmont belt of the southeastern U.S.  Further north, the wreckage was a bit lighter, because snow protected the soil during winter months.  But in the south, heavy rains were common.  Some regions eventually lost most of their soil, exposing portions of bedrock.  

Shockingly huge gullies were created in the wake of deforestation.  In Alabama, gullies up to 80 feet (24 m) deep soon followed land clearance.  One erosion gully near Macon, Georgia was 50 feet deep (15 m), 200 feet across (61 m), and 300 yards long (274 m).  Montgomery wrote, “By the early 1900s, more than five million acres of formerly cultivated land in the South lay idle because of the detrimental effects of soil erosion.”

Dust Bowl

As the colonization of the U.S. proceeded, folks continued migrating westward, moving beyond forested regions to the open prairies.  They perceived prairies to be wastelands, because they were largely treeless.  Many pushed onward toward Oregon, hoping to settle in lands having fertile soil.  In the process, they skipped right past the tallgrass prairie, home to the nation’s most fertile soil by far.  Eventually, they realized their mistake, and the primo tallgrass belt was settled. 

Latecomers got the less desirable shortgrass prairie, which had highly fertile soil, but it was lighter in texture, and more vulnerable to erosion.  In shortgrass country, strong winds and periodic droughts were normal and common, but evolution had fine-tuned the wild ecosystem to survive these conditions.

The natural vegetation was drought tolerant, retained moisture, and kept the soil from blowing away.  Unfortunately, the settlers brought state of the art steel plows, and proceeded to strip the vegetation off the land, and expose the precious soil.  Unintentional foolishness led to catastrophe.

David Montgomery mentioned a 1902 report by the U.S. Geological Survey that classified the high plains as being suitable for grazing, but not farming.  It was “hopelessly nonagricultural” because it was ridiculously prone to erosion.  Gullible farmers were encouraged by sleazy speculators to settle on the land and get rich quick.  And many did, for a while.

Walter Lowdermilk wrote that much of the time between 1900 and 1930 was a highly unusual period of above average precipitation.  During the wet years, farmers enjoyed big harvests and generous profits.  Wheat could do well in the shortgrass climate, and a thriving wheat field protected the fragile soil from erosion.  But in drought years, the wheat withered, and there was nothing to hold the soil in place when the winds began howling.

  Tractors were the latest cool gizmo.  A lad with a tractor could farm 15 times more land than a lad who used draft animals.  Cropland area greatly expanded, exposing more and more soil, which the winds carried away.  The stage was set for the Dust Bowl. 

Marc Reisner wrote, “The first of the storms blew through South Dakota on November 11, 1933.  By nightfall, some farms had lost nearly all of their topsoil.  At ten o’ clock the next morning, the sky was still pitch black.  People were vomiting dirt.”

“If not the worst man-made disaster in history, it was, at least, the quickest.”  From 1934 to 1938, there were numerous huge dust storms, “black blizzards” that could turn day into night.  In 1934, congressmen in Washington D.C. went outside to watch the sky darken at noon.  The jet stream carried dust across the ocean to Europe. 

In many regions, more than 75 percent of the topsoil was blown away by the end of the 1930s.  The Department of Agriculture estimated that 50 million acres of farmland had been ruined and abandoned during the Dust Bowl. 

Invisible Disaster

Humankind’s war on soil continues, and we’re winning.  In a 2012 article in Time magazine, John Crawford, a risk analysis expert, wrote that “A rough calculation of current rates of soil degradation suggests we have about 60 years of topsoil left.  Some 40% of soil used for agriculture around the world is classed as either degraded or seriously degraded — the latter means that 70% of the topsoil, the layer allowing plants to grow, is gone.”  [LOOK]

In some locations, visible evidence of this loss is obvious, in large clouds of dust, ghastly erosion gullies, or rain shower runoff that looks like chocolate milk.  In other places, the loss may not be readily visible during a lifetime.  When you gaze at a large field, decade after decade, you might not notice the gradual loss of tons of soil. 

Walter Youngquist mentioned a study finding that when one hectare of land lost six metric tons of soil, the surface of the soil dropped just one millimeter.  He thought that erosion was similar to cancer, a persistent intensifying destroyer.

Soils with less humus absorb less water, which increases runoff and soil loss.  Light soils are more likely to disappear than dense soils.  Sloped land is most prone to erosion.  Some regions of Europe typically receive gentle rain showers, while some locations in the U.S. often receive heavy cloudbursts.  Of course, wild grasslands and forests excel at absorbing moisture, building humus, and retaining soil. 

When forest is cleared, or grassland is plowed, the soil is exposed to incoming sunlight.  As the soil warms up, microbial activity is stimulated, which accelerates the oxidation of the carbon-rich humus.  Precious carbon built up over the passage of years is dispersed into the atmosphere as carbon dioxide.  Soil fertility declines, and will not be promptly restored, if ever. 

All tilling, to varying degrees, degrades or destroys soil.  The healthy green blanket of natural vegetation that protects the precious topsoil is entirely torn off the face of the land.  The soil dries out, hardens, and absorbs less precipitation, which accelerates runoff.  This increases the chances of sheet erosion, gullying, landslides, and flooding.  It can sometimes take centuries for nature to replace the unprotected topsoil lost in a stormy hour. 

Long ago, the Mediterranean basin became a hotbed of civilizations as agriculture spread westward out of Mesopotamia.  The Mediterranean climate provided heavy winter rains, making it a suitable place to grow wheat and barley.  Much of the basin was sloped land, which was extensively deforested over time, driven by growing demand for lumber and firewood. 

Flocks of sheep and goats roaming on the clear-cut hillsides overgrazed, encouraged erosion, and prevented forest recovery.  By and by, the rains leached out the nutrients, and washed much of the fertile soil off the hillsides.  In many locations, bare bedrock now basks in the warm sunshine, where ancient forests once thrived in ancient soils.

Carter and Dale noted that, in the good old days, the Mediterranean used to be among the most prosperous and progressive regions in the world.  But when they wrote in 1955, most of the formerly successful civilizations had become backward, or extinct.  Many had just a half or a third of their former populations.  Most of their citizens had a low standard of living, compared to affluent societies.

Montgomery noted that these ancient civilizations often enjoyed a few centuries of prosperity, as they nuked their ecosystems.  Sadly, the soils of the Mediterranean basin were heavily damaged by 2,000 years ago, and they remain wrecked today.  They are quite likely to remain wrecked for many, many thousands of years.  Much of the region that once fed millions is a desert today.

I never learned any of this in school.  Instead, this region was celebrated as the glorious birthplace of civilization, democracy, culture, and science.  It had incredible architecture and dazzling artwork.  It was home to brilliant writers and philosophers (no mention of slaves).  Many of our public buildings today, with their ornate marble columns, pay homage to this era when we first got really good at living way too hard.

Of course, progress never sleeps.  In 2000, J. R. McNeill published a fascinating (and sobering) book on the environmental history of the twentieth century, when cultures blind drunk on gushers of cheap oil spurred a population explosion that probably caused the most destruction to Earth since the Chicxulub asteroid wiped out the dinosaurs.

In a 2014 book, McNeill narrowed his focus to the catastrophic changes that have occurred since 1945.  He noted that in the world, about 430 million hectares (seven times the size of Texas) has been irreversibly destroyed by accelerated erosion.  “Between 1945 and 1975, farmland area equivalent to Nebraska or the United Kingdom was paved over.”  By 1978, erosion had caused the abandonment of 31 percent of all arable land in China.

Forest Rewrite

Greetings!  The following is a rewrite of samples 25 and 41.  They will be combined into one section and moved much later in the manuscript, before Sacred Energy.  One more step closer to the end!

 SACRED FOREST

As mentioned earlier, after the last Ice Age wound down, glaciers and ice sheets melted and retreated, eventually allowing the expansion of tundra, grassland, and forest.  Grassland spurred the momentum of the human experiment by boosting herds of game.  In wooded regions, hunting was more challenging, and forests interfered with the growth of trendy new fads like herding and farming.

This is why civilization emerged in the grassland regions of the Fertile Crescent, where wild wheat and barley grew in great abundance, as did herds of wild game.  Bountiful lands made living easier.  They also had a prickly habit of stimulating population increase.  The uncomfortable pressure of crowding and friction inspired some folks to envision escape.  Maybe they could create a more pleasant life in the forest frontier of Europe’s wild west.  Some of them packed up and left.

In Europe, Barry Cunliffe noted that as the climate warmed, wild folks migrated northward from the Mediterranean.  By 7000 B.C., they were present in a number of locations.  In lean regions they were nomadic, and in places of abundance they settled down.  At the same time, forests were also migrating northward, encouraged by the changing climate. 

By around 4000 B.C., forest expansion stopped, when it finally reached regions that were too chilly for happy trees.  By this time, folks were raising crops and herding livestock in a number of permanent settlements.  These communities were expanding their fields and pastures, which required murdering happy trees.

Over time, this increasingly abusive relationship between the two legs and the tree people led to tremendous destruction.  In the good old days, forests originally covered 95 percent of west and central Europe.  Jed Kaplan and team wrote a paper on the prehistoric deforestation of Europe.  It included stunning maps that illustrated the shrinkage of forests between 1000 B.C. and A.D. 1850. [Look]  Deforestation went into warp drive between 1500 and 1850, driven by the rise of colonization, industrialization, and other dark juju.  The voracious human swarm was swerving deeper and deeper into mass hysteria. 

Humankind’s war on forests has been intensifying for several thousand years.  It’s a huge and complex subject.  Forests have suffered from many impacts, including firestick farming, agriculture, herding, industry, warfare, construction, consumerism, climate change, and population growth.

In this chapter, I’ll share a few snapshots from the ripped and torn photo album of the relationship between two legs and the tree people. 

Humbaba’s Roar

The Fertile Crescent was where plant and animal domestication shifted into high gear.  It was in this region that the first civilizations began popping up all over, like a painful burning rash of deforestation, soil destruction, slavery, patriarchy, exploitation, aggression, self-destruction, etc. 

It’s interesting that the oldest known written story is the Epic of Gilgamesh, the saga of Gilgamesh, a lunatic king who ruled over the city of Uruk, located along the Euphrates River in Sumer (now Iraq).  By around 3100 B.C., Uruk was the biggest metropolis in the world.  Today, Uruk is a crude pile of brown rubble sitting amidst a desolate barren moonscape. [Look]  It has an important message for folks today: “Don’t live like we did.”  But humankind is a herd of sleep walkers, wandering lost in a foggy dream world.

The story was originally scratched into clay tablets in cuneiform script.  Over the course of 2,000 years, components of the story unified into a single narrative by around 1800 B.C.  In the story, King Gilgamesh was a lecherous slime ball who worked hard to expand low-tech, muscle powered, organic agriculture along the Euphrates River (a process now known as Sustainable Development™). 

Gilgamesh was probably a real king who lived somewhere between 2900 and 2350 B.C.  The growth of Uruk led to massive deforestation along the valley, which unleashed immense erosion and flooding.  In the story, Humbaba was the sacred defender of the forest.  Gilgamesh whacked his head off, and proceeded to cut trees like there was no tomorrow.  Rains then washed the soil off the mountains, down to bedrock.  And so, whenever the floods blast down the river, the noise of catastrophic destruction is referred to as “Humbaba’s roar.”  It’s the first sound I hear every morning.

Beyond Hunting and Gathering

Earlier, I jabbered about how some hunter-gatherer cultures used firestick farming to boost the availability of wild game and special plants.  This involved limiting forest, and encouraging the expansion of customized grasslands.  The tree people were never fond of this.  Over time, this expansion encouraged the intensification of farming, herding, civilization, industry, and aggressive deforestation. 

Other cultures used a different survival strategy, mindful self-control.  They understood the need to pay close attention to reality, to recognize the signs of approaching limits, and to avoid scarcity by adjusting current patterns.  Sometimes reproduction taboos were used to reduce the birth rate.  Mindfulness could avoid having an abusive relationship with the tree people, but modern society displays little interest in it.  It’s not good for jobs or the economy.

Let’s take a quick peek at the relationships that several cultures had with the tree people.  (Prehistoric dates are not certain, different sources cite different dates.)

Britain

When the glaciers of the last ice age began melting, sea levels were much lower than today.  England was connected by dry land to Ireland, Scandinavia, and continental Europe.  Barry Cunliffe noted that most of Western Europe essentially became a vast forest.  This expansion of forests displaced natural grazing land, which affected the abundance of large herbivores.

By 9000 B.C., hunter-gatherers had apparently made some small clearings in the forest to attract game.  By 6500 B.C., rising sea levels had made Britain an island, like it is today.  It was no longer connected by dry land to neighboring regions.  By 4500 B.C., when farmers and herders began to trickle in, Britain was largely a forest, except for the highlands.  Hunters dined on red deer, wild boar, aurochs, and so on.  By 3000 B.C., substantial clearances for cropland and pasture were increasing.  By A.D. 1100, just 15 percent of Britain was forest.  By 1919, it was five percent.  Britannia was essentially stripped naked, a ghastly painful open wound.

J. B. MacKinnon mentioned a story about Mark Fisher, a British scientist who visited the U.S.  From an overlook in the White Mountain National Forest, he could gaze down on 800,000 acres (323,748 ha) of woodland, an overwhelming experience.  He burst into tears and had a long, hard cry.  At Yellowstone, he saw wolves in the wild for the first time, and he dropped to his knees.  Fisher dreams of rewilding the U.K. — introducing long lost critters like beavers, lynx, wolves, and so on.

Ireland

The story in Ireland was similar to Britain in many ways, but Ireland got much more rainfall, annually receiving 50 to 200 inches (127-508 cm) of precipitation.  The wet climate encouraged the growth of lush temperate rainforests.  Frederick Aalen noted that early hunter-gatherers arrived about 8,000 years ago, when the isle was covered with a dense unbroken forest.  Folks lived along coastlines, lakes, and streams.  In the forest they created some openings to attract game, but these were apparently small in scale.

Then came a paradise-killing event of dark juju.  Farmers and herders began arriving around 3500 B.C., and the war on trees commenced.  By the end of the 1600s, the destruction of native forests was nearly complete.  When Aalen wrote in 1978, only three percent of the island was occupied by natural forest or tree farms. 

Deforestation had many unintended consequences.  William MacLeish noted that in the good old days, the rainforest wicked up a lot of moisture from the land, and then released it into the passing breezes, which carried it away.  When the trees were gone, this dispersal process wheezed.  Meanwhile, the Gulf Stream faithfully continued delivering warm rainy weather from the Caribbean.  So, the heavy rain continued, and the water remained where it landed.  Consequently, water tables rose, bogs spread, and the ground turned acid.

Deforestation blindsided the rainforest ecosystem.  The new manmade grassland ecosystem seemed to be a perfect place for raising enslaved livestock.  Winters were mild, the grass was green all year, and there was no need to grow, cut, and store hay for winter feed.  Barns were not needed to protect livestock from the cold.  Milk and meat were available all year round.  Herding worked well, but the very rainy climate made it rather risky to grow grain, despite the rich soils.

In A.D. 1185, King Henry II sent Giraldus Cambrensis to visit Ireland and produce a report.  He mentioned many beautiful lakes, where some of the fish were larger than any he had ever seen before.  Common freshwater fish included salmon, trout, eels, and oily shad.  Along the coast, saltwater fish were abundant.  The woods were home to “stags so fat that they lose their speed.”  There were numerous boars and wild pigs.  Wolves had not yet been fully exterminated.  He said it was common to see the remains of extinct Irish elks.  Their remains were usually found in bogs, often in groups.

The herding life allowed the Irish people to survive, sing, and dance.  They did not have the slightest interest in the dreary backbreaking work of agriculture, a stupid fad.  Cambrensis felt great pity for the uncivilized natives.  “Their greatest delight was to be exempt from toil, and their richest possession was the enjoyment of liberty.”

Maximum Security Forests

Rhineland

Julius Caesar roamed around Western Europe and wrote a report in 51 B.C.  He was the emperor of Rome, and his mission was to expand the Empire, collect tribute payments, acquire military conscripts, and vigorously spank uncooperative subjects.  During this campaign, he focused his attention on provinces of Celtic people in what is now France, Belgium, and England. 

He had also hoped to conquer the wild Germanic tribes that lived on the east side of the Rhine, but this fantasy promptly came to an end.  The Rhine was a large, treacherous, swift moving river.  No bridges.  It took a lot of effort and luck to get from one side to the other, and once you set foot on the German side, a super violent welcoming party was eager to immediately cut you to bloody bits.  

Each tribe preferred to keep their homelands surrounded with a barrier of uninhabited wilderness.  The Germans were primarily wandering herders who built no permanent settlements.  They had no granaries loaded with valuable food for raiders to swipe, and no roads to make invasions quick and easy.  When danger threatened, the people and their herds vanished into the deep forest mists.

For the German herders, nothing would have been dumber than to eliminate the vast ancient forests that provided this security system.  The Roman legions were fine-tuned for open battlefield combat, where heavily armored lads attacked in rigid formations.  Wild Germanic tribes excelled at hit-and-run guerilla warfare.

On the west side of the Rhine were the Celts of Gaul (France), who were subjects of the Empire.  Their forests were mostly gone, roads crisscrossed the land, and folks were forced to engage in the backbreaking misery of muscle powered organic agriculture.  Their granaries stored the result of months of hard work. 

Stored grain was treasure that villainous raiders found to be irresistibly tempting.  It was impossible for farmers to hide or quickly move their treasure.  Raiding was popular, because it was much easier than honest work.  Consequently, highly vulnerable farm communities required constant military protection, for which they had to pay dearly.  In several Western European languages, the words for “road” and “raid” evolved from a common root. 

So, the Celts that Caesar described did not reside in the primordial forest that their wild ancestors once enjoyed.  They were the opposite of wild and free.  Peasants were essentially wealth generating livestock controlled by local strong-arm elites.  On the east side of the Rhine, the Germanic tribes had not destroyed their forests.  They were alive and well, wild and free.

Tacitus was a Roman historian who wrote Germania in A.D. 98 (150 years after Caesar).  It described several fiercely independent tribes of that era.  They preferred the thrills and excitement of raiding to the drudgery of farming.  “They even think it base and spiritless to earn by sweat what they might purchase with blood.”  Perhaps they learned this effective and profitable strategy from the Romans. 

Tacitus wrote a fascinating description of the vast Hercynian forest.  From the Rhine, it spanned east, across modern Germany, to the Carpathians, and all the way to Dacia (Romania).  A quick traveler could cross the forest north to south in nine days, but it was very long, from east to west.  Caesar noted, “There is no man in the Germany we know who can say that he has reached the edge of that forest, though he may have gone forward sixty days’ journey, or who has learnt in what place it begins.” 

Pliny also mentioned it:  “The vast trees of the Hercynian forest, untouched for ages, and as old as the world, by their almost immortal destiny exceed common wonders.”  In those days, there were still a number of primeval forests in the world. 

Scandinavia

In Sweden, forests also provided freedom and security for the common folks.  Vilhelm Moberg celebrated the fact that peasant society in Sweden had largely remained stable and functional for 5,000 years.  In most of the regions of Europe, peasants endured many centuries of misery under the heavy fist of feudalism.  Many Norse and Swede settlements were lucky to be protected by their vast, dense, rugged, roadless forests.  It’s simply impossible to kill or rob invisible folks who live in unknown wilderness settlements.  Moberg glowed with gratitude for his nation’s forests, which allowed the rustic peasants to preserve their freedom until the industrial era metastasized.

Aggressive invaders from elsewhere found no roads, and soon became perfectly lost.  Behind every bush might be a man with a crossbow.  The local folks knew every hill and rock in the woods.  They could pick the ideal time and place to strike.  When trouble was advancing, they gathered as many belongings as possible, and vanished into the greenery.

My Norse ancestors told the story of Ragnarök, the twilight of the gods.  Some creepy gods had temporarily subdued nature, but in this great battle, the forces of nature rubbished the gods, and cleansed the Earth with a great flood.  Peter Andreas Munch described the dawn of a new era: “Out of the sea there rises a new earth, green and fair, whose fields bear their increase without the sowing of seed.” 

A man and woman survived.  From them sprang a new race of people.  A few minor deities also survived.  One was Vidar, a son of Odin (Viðr means forest).  Vidar was known for being strong.  His home was in a vast and impenetrable forest.  Rasmus Björn Anderson wrote that Vidar was the god of wild primordial forests, where neither the sound of the ax, nor the voice of man, was ever heard.  He is silent, dwells far away from, and exercises no influence upon, the works of man, except as he inspires a profound awe and reverence.  This was a culture filled with a deep respect and reverence for creation, in its wild and unspoiled form.  Forests were holy places. 

Forest Mining

In the transition from hunting and gathering to farming and herding, forests had served as a limit to growth — grain, grass, and herds don’t thrive in shady places.  Deforestation cleared away the towering giants and let the sunbeams shine in.  When metal axes came into common use, lumberjacks could reduce vast tracts of primeval forest into rotting stumps and erosion gullies.  Early villages and cities were built with the mutilated carcasses of countless tree people.  The rise of civilizations would not have been possible without innovative advances in unsustainable forest mining and soil mining. 

George Perkins Marsh was a brilliant American hero that few modern folks have heard of.  He published Man and Nature in 1864.  This gentleman from Vermont served as the U.S. Minister to Italy.  While overseas, he visited the sites of many once thriving civilizations in the Fertile Crescent.  What he observed was terrifying and overwhelming.  Each of them had seriously damaged their ecosystems and self-destructed in similar ways.

Massive levels of soil erosion created surreal catastrophes.  He saw ancient seaports that were now 30 miles (48 km) from the sea.  He saw ancient places where the old streets were buried beneath 30 feet (9 m) of eroded soil.  He stood in mainland fields, 15 miles (24 km) from the sea, which were formerly located on offshore islands.  He saw the sites of ancient forests, formerly covered with three to six feet (1-2 m) of precious living soil, where nothing but exposed rock remained. 

Far worse, Marsh was acutely aware that every day, back home in America, millions were currently working like crazy to repeat the same mistakes, glowing with patriotic pride at the temporary prosperity they were creating on their one-way joyride to oblivion.  In a noble effort to cure blissful ignorance, he fetched pen, ink, and paper and wrote a book to enlighten his growing young nation.

Sales were respectable for a few decades, but America did not see the light and rapidly reverse course.  Folks thought that the cure was worse than the disease (like today’s climate emergency).  A radical shift to intelligent behavior would not have been good for the highly unintelligent lifestyle.  Tom Brown’s mentor, Stalking Wolf, lamented that our culture was “killing its grandchildren to feed its children.”

Marsh’s book has stood the test of time fairly well.  It presented a wealth of vital information, none of which I learned about during 16 years of education.  Forests keep the soil warmer in winter, and cooler in the summer.  Springtime arrives later in deforested regions, because the land takes longer to warm up.  Forests absorb far more moisture than cleared lands, so after a good rain, runoff is limited, and flash floods are less likely.

Deforestation dries out the land.  Lake levels drop, springs dry up, stream flows decline, and wetlands are baked.  Back in the fourth century, when there were more forests, the water volume flowing in the Seine River was about the same all year long.  When Marsh visited 14 centuries later, water levels could vary up to 30 feet (9 m) between dry spells and cloudbursts.  In 1841, not a drop of rain had fallen in three years on the island of Malta, after the forest had been replaced with cotton fields.  And on and on.  The book is a feast of essential knowledge. 

Walter Lowdermilk was deeply inspired by Marsh’s work.  In the 1920s and 1930s, he visited China, Western Europe, North Africa, and the Middle East.  His mission was to study soil erosion, and write a report for the U.S. Department of Agriculture.  They created a short booklet that was very readable and filled with stunning photographs.  Over a million copies of it were printed.  Conquest of the Land Through Seven Thousand Years is available as a free download. [Link]

Industrial Wood

Marsh generally discussed the environmental impacts of deforestation that he had observed at the sites of extinct or wheezing civilizations.  These catastrophes were usually the unintended consequences of clearing forest to expand cropland or grazing land.  Over the passage of centuries, clever people discovered many new ways that dead trees could be used to generate wealth and power. 

John Perlin wrote an outstanding history of deforestation.  It’s a modern book (1989), and much easier to read than Marsh.  It devotes more attention to the political, military, industrial, and commercial motivations for forest mining.  It visits locations including Mesopotamia, Crete, Greece, Cyprus, Rome, Venice, England, Brazil, and America. 

Dead trees were used to build houses, bridges, temples, and palaces.  Wood was made into fences, docks, wagons, furniture, tools, and barrels.  It heated homes and fueled industries that produced metal, glass, bricks, cement, pottery, lime, sugar, and salt.  Staggering quantities of wood were consumed by industry.  Very importantly, wood was used to build cargo, fishing, and war ships.  Navies sped the spread of colonies, empires, trade networks, and epidemics.

Cultures that mindfully limited their numbers, and continued living in a low impact manner, had no future.  Their thriving unmolested forests looked like mountains of golden treasure in the eyes of civilized sailors cruising by — and civilized people cannot tolerate the sight of unmolested forests; it drives them nuts.  In other words, if you didn’t destroy your forest, someone else would. 

Perlin described the copper industry on Cyprus in around 1300 B.C.  Copper was used to make bronze, which was in high demand during the Bronze Age.  For each 60 pound (27 kg) copper ingot produced, four acres of pine (120 trees) had to be reduced to six tons of charcoal.  Each year, the copper industry on Cyprus consumed four to five square miles (10-13 km²) of forest.  At the same time, the general society consumed an equal amount of forest for heating, cooking, pottery, lime kilns, and so on.  Can you guess what inevitably happened to the forests, soils, industry, and affluence of Cyprus?

Shortages also affected the use of firewood.  In chilly regions, a city of one square mile might depend on 50 square miles of forest to provide the firewood it consumed year after year.  In the good old days, this was often possible.  Later, as forest area decreased, and population grew, limits spoiled the party.

If Perlin’s work sounds interesting, but you can’t get his book, a similar book is available as a free download.  In 1955, Tom Dale and Vernon Gill Carter published Topsoil and Civilization.  Readers are taken on a neat journey, during which they discover how a number of ancient civilizations destroyed themselves.  The free PDF is HERE.  It is not available in some countries, for copyright reasons, but I once saw a pirate copy on Google.

New World Forest

Richard Lillard described how early European visitors experienced the ancient forests of North America.  When standing on mountaintops, they were overwhelmed by the fact that as far as they could see in any direction there was nothing but a wonderland of trees.  The intense experience of perfect super-healthy wildness was surreal, overwhelming, almost terrifying. 

Walking beneath the canopy at midday, the forest floor was as dark as a cellar, few sunbeams penetrated through the dense foliage.  At certain times, some sections of the forest were absolutely silent, a spooky experience that bewildered the white folks.  They saw vast numbers of chestnut trees that were nearly as big as redwoods. 

British visitors to early settlements were stunned to see amazing luxury — wooden houses, sidewalks, fences, and covered bridges!  Commoners were free to hunt large game because the forest was not the exclusive private property of anyone.  In the old country, their diet majored in porridge.  Now it could major in wild grass-fed meat.  Commoners were free to cut as much firewood as they wished, and keep their cottages warmer than the castles of royalty.  Michael Williams mentioned one winter night when the king of France sat in his great hall.  He was shivering as he ate dinner, the wine in his glass was frozen. 

William Cronon noted that settlers with sharp axes went crazy on the forests, cutting them down as if they were limitless.  Lots of excellent wood was simply burned, to clear the way for progress.  They built large houses, and heated them with highly inefficient open fireplaces.  By 1638, Boston was having firewood shortages.

As clearing proceeded, summers got hotter, and winters colder.  As stream flows dropped in summer, water-powered mills had to shut down, sometimes permanently.  In winter, upper levels of the soil froze solid on cleared land, and snow piled up on top of it.  When springtime came, the frozen land could not absorb the melt, so the runoff water zoomed away, and severe flooding was common.

Stewart Holbrook wrote about the fantastically destructive obliteration of ancient forests in the U.S. upper Midwest.  On the same day as the great Chicago fire, October 8, 1871, a firestorm obliterated the backwoods community of Peshtigo, Wisconsin, killing five times as many people as in Chicago.  On this day, the new word “firestorm” was added to the English vocabulary. 

Holbrook interviewed John Cameron, an eyewitness to the Peshtigo fire.  Cameron noted that there had been little snow the previous winter, and just one rain between May and September.  Streams were shallow, and swamps were drying up.  Logging operations left large amounts of slash in the woods (piles of discarded limbs and branches).  Slash piles were eliminated by burning, even when it was very hot, dry, windy, and extraordinarily stupid. 

The morning of October 8 was hotter than anyone could remember, and the air was deadly still.  At noon, the sun disappeared.  By nightfall the horizon was red, and smoke was in the air, making their eyes run.  At 9 P.M., Cameron heard an unusual roaring sound.  The night sky was getting lighter by the minute.  A hurricane force wind howled through.  Suddenly, swirling slabs of flames were hurtling out of nowhere and hitting the bone dry sawdust streets.  In a flash, Peshtigo was blazing — maybe five minutes. 

Cameron saw horses, cattle, men, and women, stagger in the sawdust streets, then go down to burn brightly like so many flares of pitch-pine.  He winced when he spoke of watching pretty young Helga Rockstad running down a blazing sidewalk, when her long blond hair burst into flame.  The next day, he looked for her remains.  All he found was two nickel garter buckles and a little mound of white-gray ash.

The river was the safest place that night.  People kept their heads underwater as much as possible, so the great sheets of flame wouldn’t set their heads on fire.  Within an hour, the town was vaporized.  Big lumberjacks were reduced to streaks of ash, enough to fill a thimble.  In this village of 2,000, at least 1,150 died, and 1,280,000 acres (518,000 ha) went up in smoke.

Also on October 8, 1871, numerous big fires raged across the state of Michigan, where it had not rained in two months.  These fires destroyed 2.5 million acres (1 million ha) — three times more timberland than the Peshtigo blaze.  This was an era of countless huge fires.  For example, in just the state of Wisconsin, tremendous fires destroyed huge areas in 1871, 1880, 1891, 1894, 1897, 1908, 1910, 1923, 1931, 1936.

Paul Shepard wrote, “Sacred groves did not exist when all trees were sacred.”  In 1990, I chatted on an internet bulletin board with a Shawnee man named Nick Trim.  He talked about a project 300+ years ago, along the Mississippi.  In a kindly gesture, some French soldiers were teaching the Shawnee how to build log cabins.  This required cutting trees.  The natives were very nervous about chopping down living trees, because they were often home to spirit beings, the little people.

To avoid spiritual retaliation, a respectful process was essential.  They knocked on each tree, described the situation, and explained why they wanted to take lives.  This was followed by a ceremony, prayers, and apologies to the trees.  Then they waited a day or so, to give any spirit residents adequate time to find a comfortable new home.  This took so long that the French lost their patience, and the project ended.

Peter Wohlleben, a German wood ranger, developed an extremely intimate relationship with the forest he cared for, and wrote a precious celebration of his love for it.  Modern folks who spend most of their lives in civilized space stations almost never get to know the tree people.  Some do not eat meat because they sense that animals have souls.  In an interview, Wohlleben conveyed a deeper understanding.  Killing an animal is the same as killing a tree.  He once oversaw a plantation of trees lined up in straight rows, evenly spaced.  It was a concentration camp for tree people.

Aztec Erosion

M. Lourdes González-Arqueros and team studied soil erosion in the Teotihuacán Valley, northeast of Mexico City.  Mexico’s soils have taken a beating over the centuries, and the blame is commonly directed to the settlers from the Old World who arrived in the 1500s.  They imported many destructive practices, pathogens, and hooved locusts (goats and sheep).  Research done by the study concluded that the indigenous people were already reputable soil molesters when the white folks arrived.  They analyzed erosion patterns during three different periods of time:

(1) In the Teotihuacán period (A.D. 1-650), forests still grew on summits, hill slopes, and foot slopes.  This restricted some soil erosion.  Organic corn was grown by no-tillage methods (picks and spades) on the lower ground. 

(2) In the Aztec period (1325-1521), forest area in the valley was drastically reduced as population increased, and agriculture expanded up the hillsides.  During this period, much of the landscape was devoted to agriculture.  When sloped land is deforested, increased erosion is an expected consequence.  In the Aztec period, rates of soil loss were much higher, compared to rates in both the earlier Teotihuacán period, and the later modern period.

(3) In the modern period (after 1970), forest area has recovered a bit.  A large portion of cropland is now planted with prickly pear, a perennial plant that is fast growing, rapidly rooting, and usually has deep roots.  Soil destruction was lower than during the Aztec period, but the study did not give modern practices the Sustainable Agriculture™ seal of approval.  Too many people continue living too hard.

The team concluded that land use and soil management were prime factors in the erosion, more so than precipitation and topography.  I wish their study hadn’t skipped around the years between 1521 and 1970.  Anyway, before the Spaniards, the land was gradually being beaten to death.  Then, the colonists launched a full scale war on forests, while flocks of their imported sheep and goats prevented forest recovery, and their overgrazing accelerated erosion. 

Then, around the 1960s, the Green Revolution rolled in, with mechanization, water mining, synthetic fertilizers, hybrid seeds, and trainloads of chemical fertilizers, fungicides, herbicides, and pesticides.  Around the world, population continues soaring, while staggering amounts of soil run away from home.  In the modern mindset, unborn generations, ecosystems, and the atmosphere are seen as disposable — cosmic litter, like plastic water bottles or cigarette butts.  Our education system is completely lost in a soft, warm, foggy dream world of full blown dementia (perpetual growth, electric cars, voyages to Mars). 

Oh!  Speaking of Mars, he was the Roman god of war in his glory days.  Earlier in his career, he was a deity of virility, fertility, springtime, and a guardian of agriculture.  Farmers hated nature, because wildness refused to behave like an obedient servant.  It was hard work clearing forests, stripping away the wild vegetation, exterminating the wildlife, and pulverizing the soil.

Nature was a mortal enemy of the Roman Empire, because it was a persistent threat to their food supply.  Trees, brush, grass, and critters constantly invaded the wheat fields.  Every day, Big Mama Nature worked hard to restore health to badly injured ecosystems.  She used all her tricks to rubbish the hideous fields — droughts, deluges, hail storms, frosts, heat waves, howling winds, wildfires, locusts, blights, birds, deer, boars, and on and on.

She also used pandemics.  One of my ancestral homes was in Gran, Hadeland, Norway.  The Black Death hammered the population, many farms were abandoned, and joyful forests reclaimed their fields.  My kin told me that one day, many years ago, a lad was hunting in the woods.  He shot an arrow, and it struck a bell.  He was surprised to discover an old church concealed in the dense forest.  Nobody among the living knew anything about the mysterious church, or the community it had served before the plague.

Mixtec Erosion

The Mixtec culture of southern Mexico is ancient.  Their homeland is mostly located in the state of Oaxaca which, long ago, was one of the most advanced regions in the Americas.  The Mixtec people managed to avoid being absorbed by the Aztec empire, and their writings are much older than those of the Aztecs or Incas.  Some believe that the Mixtecs were the ones who originally conjured domesticated corn out of wild teosinte.

In the good old days, prior to agriculture, their homeland was largely forest.  Today, regions of the treeless highlands have become a desert that not even thorns can grow in.  Oaxaca is Mexico’s second poorest state, and a third of its people have moved away.  Photographer Matt Black happened to meet some Mixtecs in California, where they were accumulating vast fortunes by doing backbreaking farm labor for $40 a day.  They chose this path because their homeland had become a disaster area.  Many of them are illiterate, and most speak only their native language, Mixteco.

In 2011, Black got curious about them and decided to visit their homeland, Mixtecapan (the place of the Cloud People), one of the world’s oldest farming cultures.  Wow!  Some places have lost up to 16 feet (5 m) of topsoil.  A number of villages are half-deserted, and some of their fields have eroded to bare bedrock.  More than a million acres are so severely damaged that the U.N. now calls the region one of the most heavily eroded landscapes in the world.

Most stunning of all, Black described the disintegrating village of Santiago Mitlatongo.  One day, a cliff above town fell apart, dumping stones as large as houses on the village below.  Whole cornfields disappeared into sinkholes.  Homes sank into the ground and vanished.  Eventually, the whole village broke away from the surrounding land, like a calving iceberg — homes, fields, churches, stores — an area of about two square miles (5 km²) was in motion.  Writing in 2012, Black noted that it was still sliding, a few feet per day, a half mile (804 m) away from its original location. 

Corn Blight

H. Arnold Bruns wrote about a serious corn blight that hit the U.S. in 1970-71.  The southern corn leaf blight (SCLB) destroyed 15 percent of the corn crop.  It was enabled by innovative plant breeding that focused on maximizing yield ($$) by designing highly productive hybrid seeds that had very little genetic diversity.  These hybrids reliably generated big money for farmers, who eagerly bought the magic seeds.

On the downside, when conditions were optimal, up to 85 percent of the corn in a field was highly vulnerable to SCLB fungus.  The winter and spring of 1970 were wetter than usual, providing ideal conditions for disaster.  Some farmers lost 80 to 100 percent of their crop.  In the Corn Belt, some clusters of counties had average losses of 35 to 50 percent.  Across all of the state of Mississippi, losses were 30 to 40 percent.  This inspired big fear.  Would the entire U.S. crop be lost?  What would we use to feed livestock and poultry?  No more whiskey?  Gulp!

Before 1930, almost all corn was allowed to pollinate naturally, which resulted in high genetic diversity that reduced the possibility of catastrophic blights.  Then came the hybrids which, in theory, were more vulnerable to crop failure, but they almost always provided far higher yields and profits.  Today, in the major corn growing nations, 97 percent of the corn planted is hybrids.

The amount of food energy lost because of the SCLB blight was greater than the lost food due to the potato blight of Ireland in the 1840s, during which the Brits made little effort to feed the starving.  The message of both blights is that there is great danger in growing monocultures of extremely uniform crop plants.

Today, Brun worries that the new GMO fad is busy creating ideal conditions for bigger and better disasters — billions of herbicide resistant seeds having dangerous genetic uniformity.  What could possibly go wrong?  Right now, a blight is working hard to drive a stake into the heart of the banana industry — and winning.  The entire crop is genetically identical clones.

The Curse of the Soil Molesters

If you are a lucky one, and your high school education provided you with a competent understanding of environmental history, you would probably be bored out of your mind by now, reading my tiresome jabber about stuff that every teen should know.  But, if you have been institutionalized for years in a more typical school system, there’s a chance that you’re stumbling through some uncharted territory here.  If so, it’s time we had an embarrassing “birds and bees” talk about soil molesters — the naughty things they do in their fields, and how their actions harm the region, the nation, the generations yet to be born, and the long term health of the planet’s ecosystem.

The birds and bees talk I got at age 15 had to do with boys, girls, sex, and reproduction.  The primary objective was to help kids avoid unintended and unwanted pregnancies.  With regard to my relationship with soil, I never got a similar talk, I had to figure it out on my own.  If we want to avoid ignorantly creating unwanted wastelands, the safe and effective prevention is abstinence — never, never, never engage in invasive and abusive forms of intercourse with highly fertile ecosystems.  Remember how our wild ancestors lived.  Think!

At the dawn of agriculture in Mesoamerica, folks majored in growing corn, beans, and squash.  They used techniques that were similar to other regions of the world where plant domestication emerged.  Their farm equipment was digging sticks and hoes, so the first places they molested were often along shorelines, rivers, wetlands, and flood plains, where the soils were soft and moist.  When the planters first rammed their digging tools into fertile virgin soil, the initial harvests could be impressive.  But with every year, when a field was replanted, the nutrients in the soil were a bit more diminished, and the harvest was a bit smaller. 

Depending on soil quality, a field could produce decent autumn harvests for up to maybe six years.  When “evil spirits” (nutrient depletion) eventually reduced yields, the field was abandoned, and a new one was cleared.  The abandoned field might be given a rest for maybe 10 or 20 years, to recharge its soil a bit.  Then, it might be cleared again, and returned to production for a while.  This cycle might be repeated a few times, sometimes for several generations, but not forever.  There is no free lunch.  Long term agriculture is a progressive and terminal pathology.

In Mesoamerica, this was called the milpa system, in other regions similar practices were called slash and burn, swidden, or shifting agriculture (milpa means corn field).  Milpa is the opposite of wild and free.  Big Mama Nature adores healthy soil, and strives to protect it.  Where rainfall is generous, she clothes the land with forest.  Where rain is more modest, she covers the soil with grassland.  Wild and free has three huge benefits.

(1) Protected soil retains moisture better than bare naked soil that is exposed to the sun and wind.  Consequently, wetter soil encourages a wetter ecosystem, promoting the existence of springs, streams, ponds, wetlands, and a greater abundance of many forms of life.  Magnificent swamps are home to far more biodiversity than deserts.  Both forests and wild grasslands send roots deep into the ground, so they can better retrieve nutrients and water, hold the soil in place, and continuously improve soil health and fertility with each passing century. 

In the milpa system, the primary crops are annuals, plants that live just one season and then die.  Trees and many grassland plants are perennials, plants that have longer lifespans.  Annuals have to be replanted every year, after the farmer first pulverizes the soil surface.  This disturbance encourages some of the precious carbon stored in the soil to be released into the atmosphere.  It also encourages the moisture in the soil to evaporate, which makes annuals more vulnerable to drought.

(2) Protected soil is held in place by the green blanket of vegetation, which prevents it from being blown away by the wind, or washed away by rain or snowmelt.  Bare naked sloped land is especially prone to water erosion, which can rip deep gullies into hillsides over time.  Earlier, I mentioned the catastrophic erosion in the Yellow River watershed that created gullies 600 feet deep (183 m).  Paul Shepard noted that massive erosion in the watershed of the Tigris and Euphrates Rivers dumped so much soil into the Persian Gulf that 35,000 square miles (90,650 km²) of salt marsh was created.

Once upon a time, on a lovely Sunday in June, Wes Jackson was driving through Mennonite country in Kansas.  He stopped to observe a Mennonite’s field, which had recently been planted.  During the previous night, a hard rain had dumped up to five inches (12 cm) in some places, a normal event in that region.  Mennonites devote extra effort to being good stewards of the land.  Compared to industrial agriculture, their methods have lower impact.  Looking at the field, Jackson observed that the rain had washed the seeds away, and the ditches were clogged with rich black mud.  It was a wipeout. 

Then, Jackson went to inspect a prairie not far away.  It was not damaged at all.  In fact, it had been invigorated by the refreshing rain, and none of its soil had run away.  Prairies can absorb 14 times more moisture than tilled cropland.  Forests and prairies can be fairly eternal, but cropland has an expiration date.  Sooner or later, the soil is depleted, and the cropland becomes wasteland.  This can take many generations, it’s not an immediate house-on-fire threat, so it’s easy to pretend that all is good.  But the damage caused is cumulative and almost always irreparable.

Richard Manning noted that a healthy wild prairie can absorb 5 to 7 inches (13-18 cm) of rain in an hour with no runoff.  A field of corn or soybeans can absorb 0.5 to 1.5 inches (1.3-3.8 cm) in an hour, and the excess water runs off almost as fast as from a parking lot.  This difference explains the catastrophic 2008 floods in the U.S., following several days of generous rainfall.

(3) Protected soil is often an ongoing miracle of continuous improvement.  Several thousand years ago, as the glaciers melted, Iowa’s soil was exposed to warm sunbeams for the first time in ages.  Vegetation recovered and, with each passing century, the happy prairie created an ever growing layer of tremendously fertile black topsoil.  Before settlers arrived in the nineteenth century, the soil was remarkably deep in places.  Because the sod layer was so healthy, thick, and rugged, native people with corn seeds could not rip it open with digging sticks or hoes — much to the delight of the prairie, and Big Mama.

The Iowa Association of Naturalists became freaked out by soil erosion in Iowa.  In 1999, the state was losing 240 million tons of its “black gold” every year.  This incredible treasure of soil had been created over thousands of years by a thriving tallgrass prairie.  Half of it had been lost since 1848, as the settlers launched a full-scale war on the soil, armed with the insanely destructive steel moldboard plows manufactured by a demon-possessed madman named John Deere.

Jared Diamond once visited Iowa, and observed a church in corn country that was more than 100 years old.  He said that the churchyard was like a table, a plateau elevated ten feet (3 m) above the surrounding fields, which had been savagely molested by the radicalized fanatics of the Deere cult.

Geologist Walter Youngquist noted that half of Iowa’s topsoil had been flushed down the Mississippi River, and dumped into the Gulf of Mexico.  On some Iowa hills, streaks of the ancient tan and gray marine clays, which had long been buried under the black gold, were beginning to see the light of day once again.  He wrote, “The great enemy of soil and, therefore, civilization, is civilization itself as we know it — the human-induced accelerated rate of erosion.”  From a human timescale, topsoil is a finite nonrenewable resource.  Destroying it is foolish.

The Danse Macabre

The emergence of plant domestication in both the Old World and the Americas typically triggered a devastating chain reaction of consequences — increased food production, deforestation, soil destruction, ballooning population, technological innovation, social stratification, bloody warfare, patriarchy, empire building, civilization, megalomania, ridiculous decadence, collapse, and ruins.  Then, if anything was left of the ecosystem, folks dusted themselves off, regrouped, and repeated the same mistakes, again and again, until the land was absolutely and permanently wrecked.

The transition to domestication, in multiple regions, was an extreme shift away from maybe two million years of the traditional hunter-gatherer way of life.  Our wild ancestors rocked the boat far, far less.  They were lucky to enjoy a very long era of wild, free, and happy — the calm before the storm (or the wellbeing before the epidemic).

William McNeill wrote that both plants and animals can become hosts to diseases.  Some microparasites simply enjoy an ongoing free ride on their hosts, snatching some nutrients, but not too many.  Others seriously weaken their hosts and kill them.  McNeill imagined that, in addition to plants and animals, there was a third category of hosts — ecosystems.  Over time, some human societies became foolishly clever, and mutated into macroparasite (large predator) roles, attacking and degrading healthy ecosystems.  McNeill thought that the relationship between these rogue societies and the family of life came to resemble “an acute epidemic disease.” 

When agriculture escaped from Pandora’s Box of powerful evils, it created something like a devastating infection in the family of life.  This reminded me of a meme from the era of bubonic plague epidemics: the dance of death.  Everyone was sick and dying, especially the priests, who visited the sick.  Why didn’t God even protect his own special agents?  Hello?  Many lost their faith.

Johannes Nohl reported that during plague years, a number of communities in Europe engaged in country dances, in order to dispel depression.  In 1424, a Scottish lad named Maccaber arrived in Paris.  Folks believed he had supernatural powers.  He initiated an ecclesiastic procession, the Maccaber Dance (Danse Macabre) — the Dance of Death.  Every day, for months, crowds of men and women danced in the cemetery.  Folks wore scary masks to drive away the evil spirits.

The notion of a dance of death is sort of a fitting description for how ecosystems were impacted by the emergence and expansion of agriculture.  Let’s sketch out a generic pattern for how agriculture triggered its own whirlwind of evil spirits.  The horror began with clearing and planting in soft moist soils.  This led to more food, more people, and tired soil.  This led communities to gradually expand the size of the milpa, until it reached the limits of prime locations to deflower.  Then, planting began to move up slopes.  If forests covered the slopes, as they often did, the tree people were chopped down.  This led to more food, more people, more soil depletion, and more erosion and gullying.

As communities expanded their realms, at some point they were likely to bump into other communities, and generate some friction and sparks.  The survival of each settlement required folks to protect their stores of corn and beans — precious treasures that opponents were eager to swipe or destroy.  Consequently, many Native Americans surrounded their communities with tall and sturdy wooden palisades.  Dean Snow wrote that corn spread into Iroquois country around 1350 to 1400.  Population grew, villages got larger, longhouses got longer, and most villages had double or triple palisades.  This defensive strategy was similar to the Old World practice of building fortifications, moats, and walled cities.

In the conflict game, the cardinal rule is strength in numbers.  At first, a village might be managed by a tribal chief.  Then, multiple villages would unite, and live under the protection of a warlord.  Later, these alliances merged together into kingdoms or empires.  Communities that prepared for conflict were more likely to survive than communities that attempted to avoid the mother of conflict via family planning — reproductive taboos.  By and by, civilizations appeared, and initiated full-scale warfare on ecosystems.

Big shots in lofty power centers got very big headed and heavy handed.  Their minds floated in a giddy dream world, soaring with grandiose infantile visions of full dose megalomania.  One day, in an online encyclopedia, I was looking at a discussion of pre-Columbian (before 1492) civilizations in the New World.  I was suddenly walloped by a mind expanding dope slap.  SMACK! 

My eyes scanned a series of photos of ancient Mesoamerican ruins.  They were strangely similar in many ways — huge pyramids, elevated temple platforms, sculptures, palaces, streets, and plazas.  It was spooky how these New World images resembled the ruins created by the early civilizations in the Fertile Crescent and the Mediterranean basin.  Civilizations around the world, totally isolated from each other, clearly exhibited symptoms of the same acute disease — the curse of cleverness, domination, patriarchy, and self-glorification.

Why were so many people forced to spend their lives engaged in monumental construction projects that survived centuries longer than the brief explosion of decadence and egomania that created them?  What could be more ridiculous?  Well, (blush!) today’s industrial civilization has succeeded in boosting human foolishness and mindless destruction to levels never before believed to be possible.  No generation has created more and bigger ruins than the voracious mob alive today.

Beginning around 1200 B.C., a series of New World civilizations appeared here and there, aggressively devoured their resource base, enjoyed a giddy orgasm of debauchery, and then plummeted into oblivion.   The parade included the Olmecs, Mayans, Aztecs, Toltecs, Oaxacans Incas, Mixtecs, Zapotecs, and so on.  This pattern of growth and collapse was also the norm in many regions of the Old World — Uruk, Babylon, Phoenicia, etc.  Like fireflies, they blink on for a moment, then off.  In unsustainable cultures, what goes up must come down, no exceptions.

Old World civilizations were fuelled by junior grade propellants like wheat, barley, and rice.  New World civilizations were turbocharged by two highly potent propellants: corn and potatoes.  Clive Ponting noted that in A.D. 600, wheat powered Rome was home to 50,000.  At that time, in the Valley of Mexico, corn powered Teotihuacán was home to 100,000 (others say 150,000).  It is located about 18 miles (30 km) northeast of Mexico City. 

The Old World had many powerful things that Mesoamerica did not — livestock, horses, wheels, ships, and advanced metallurgy.  Maybe the Romans were handicapped by their inferior food, or by the persistent barbarian attacks, or by the waves of infectious diseases nurtured by animal domestication, or by their soils depleted by several centuries of wheat farming, or by their lead pipe water distribution system.

In 600, hungry dirty Europeans were struggling to survive in what we now call the Dark Ages, while Teotihuacán was a state of the art masterpiece of monumental architecture (look at online images).  There was the Street of the Dead, the Pyramid of the Sun, and the Pyramid of the Moon.  Aztecs ominously referred to Teotihuacán as “the place where men became gods.”  The society was destroyed in about 650, and everything flammable was burned.  By 900, it was an abandoned ghost town.

Much later, in 1521, when Spaniards arrived, the Aztec civilization of Tenochtitlán (Mexico City) was one of the biggest cities in the world, with a population of about 200,000 (some say 250,000), which was five times larger than London.  The invaders were amazed to see a big city in which the streets were not stinky and slippery with deep horse shit.  Aztecs are also known as the Mexica.

In an effort to recycle soil nutrients, the Aztecs fertilized their fields with human poop.  Imagine how much poop 200,000 people can plop every day.  Imagine continuously moving that poop out to the cornfields — without the benefit of wheeled carts or (nonhuman) beasts of burden.  Despite challenges, their population was soaring to new heights — until Old World diseases rumbled into town like a mega-death steamroller.

Several of the Spanish invaders wrote down accounts of what they observed, including the Aztec rituals of human sacrifice.  Prisoners were taken to the top of the temple-pyramid, where they were cut open, their beating heart removed and offered to the sun, and their corpse kicked down the steps.  Several Spaniards estimated that the number of folks sacrificed was maybe 20,000 per year.  On one especially sacred occasion in 1487, according to Aztec sources, the dedication of the main pyramid in Tenochtitlán was even bloodier, possibly more than 80,000.

Michael Harner focused his attention on the human sacrifices.  What was their purpose?  He noted that scholars tended to consider the practice shocking, but sacrifices were not unique to Mesoamerica.  Old World cultures had their own tradition of bloody mass murders that were inspired by periodic outbursts of holy hysteria and rabid intolerance.

Harner contemplated the notion that there was more to the rituals than good old fashioned religion.  Long before the rise of the Aztec culture, the deer in central Mexico had been hunted to scarcity.  Tenochtitlán was built on a manmade island on the western shore of Lake Texcoco.  The lake was too shallow and salty for fish to live in, so the meat department majored in domesticated turkeys and hairless dogs (Chihuahuas).

In the Andes, the Incas also performed sacrifices, but on a much smaller scale.  Their meat department was more generous, including llamas, alpacas, and guinea pigs.  Because long distance travel was extremely difficult, the people of the Andes didn’t acquire turkeys or Chihuahuas from Mexico, but they did get corn.  On the other end, Mesoamerica did not acquire llamas, alpacas, guinea pigs, or potatoes from the Andes.

While it’s possible to be fairly well nourished on a diet majoring in corn and beans, it takes some luck.  Both have to be consumed during the same meal, in adequate portions, in order to assemble essential proteins.  Adding some meat to their diet could help compensate their protein requirements.

John Reader noted that fat is essential for the absorption, transport, and storage of vitamins A, D, E, and K.  Growing children especially need two types of fat.  Arctic folks can enjoy excellent health on a diet of blubber and raw meat, but Aborigines would abandon a kangaroo that had too little fat.

Reader noted that we need to consume 40 to 50 nutrients, including carbs, fat, protein, 14 vitamins, and 15 minerals.  The building blocks of proteins are 22 types of amino acids.  From the food we eat, we can assemble 12 types of amino acids.  We cannot assemble the other 10 types, they must be consumed readymade.  These are called “essential” amino acids.  All 10 are present in plant foods, but not in the ideal proportions.  When our diet is missing just one essential amino acid, protein assembly ceases. 

It is possible to get by on a combo of cereals and beans, but this option was not practical until the era of agriculture.  For non-farmers, meat is an essential component of a healthy diet.  Different types of animal foods provide proteins, but we need to reassemble them into forms that our bodies need.  Reader said that the one and only animal food that provides the exact mix of required proteins readymade is human meat.  Full scale cannibal cultures are impossible, because the rate of consumption would far exceed the rate of reproduction.

Harner proposed the theory that the Aztec sacrifices had two roles, one was religious, and the other was about reducing malnutrition.  Aztecs often raided their neighbors, and brought back prisoners.  They did not annex their land, but they left behind survivors to breed replacements that could be captured during future raids.  Prisoners who were not eaten on the battlefield were taken back home, where they were kept in sturdy wooden cages, in which they were fattened up for an upcoming sacrifice.

Bernal Díaz was a Spaniard who was an eyewitness to sacrifices.  He wrote:  “Moreover every day they sacrificed before our eyes three, four, or five Indians, whose hearts were offered to those idols and whose blood was plastered on the walls.  The feet, arms, and legs of their victims were cut off and eaten, just as we eat beef from the butcher’s in our country.”

In the sacrifice process, the heads were also removed.  In Tenochtitlán, their skulls were displayed on a rack near the temple.  Two soldiers were assigned the job of estimating the number of skulls on the rack.  They concluded about 136,000 skulls (not including the ones on the towers).  Sacrifices were also normal events in other Aztec cities.

As school children, we were taught that civilization was an outstanding achievement, a great leap forward.  We also learned that our wild ancestors, who had far less eco-impact, were primitive, stupid, and pitiable.  Their lives were “nasty, brutish, and short.”
