Every serious ecological signal says the pressure on the planet has to come down. Yet every major institution insists the economy must keep growing. When national birth rates fall, leaders do not express ecological relief; they panic.
If overshoot—using resources faster than the planet can replace them—is real, why does the whole system still demand more bodies?
Modern capitalism did not appear from nowhere.
It is the latest iteration of an older machine. To understand how we got here, we have to look at the origins and evolution of human civilization.
The Dawn of Civilization Twelve thousand years ago, the Earth’s climate stabilized [1].
Before this, the planet’s orbit and tilt pushed the Earth in and out of ice ages. Because the climate was unpredictable, humans moved, following food.
When the seasons became predictable, human behavior could change. Humans already knew how to collect seeds and spread plants, and stable seasons made it possible to apply that knowledge to a fixed location. Wheat, rice, oats, barley, and other domesticated grains are drastically different from their wild versions. These plants
are grasses, and what humans eat is their seeds. Wild seeds evolved to hitch a ride with animals in their fur so they could spread further out. When a heavy animal hits a wild grain plant, the seed head immediately shatters into pieces, scattering the seeds across the soil. This defense mechanism ensures that a single animal cannot eat the entire harvest, leaving seeds behind to grow next year. Humans were just one of the many animals gathering these wild seeds.
Early humans noticed that some mutant plants did not shatter upon touch. Because this made the plants much easier to harvest, humans intentionally planted these seeds to grow more of them. Over time, these mutants—which otherwise would have been at an evolutionary disadvantage—spread rapidly because they had a partner: humans [2]. Nomadic groups knew this and practiced this kind of selective farming well before they became settled in one place.
As the environment shifted to a more predictable pattern, it became far less necessary to move. People often stayed put, continually planting the versions of foods they preferred until the plants became domesticated. The grains were now dependent upon humans to spread, and humans became dependent upon the grains.
Prior to 12,000 years ago, the human population grew slowly at around 0.05 percent per year. Following the widespread adoption of agriculture, the demographic growth rate in some regions jumped to over 1 percent, an increase of more than twenty-fold [3].
Grains changed the mathematics of human reproduction.
Humans and other great ape infants are highly dependent on their mothers. A chimpanzee or gorilla mother will breastfeed her child until four to five years of age; an orangutan mother nurses for six to seven years. Apes wean their offspring precisely when the young animal is capable of foraging for itself.
Human maturation is one of the slowest in the animal kingdom, and human diets rely heavily on cooking and processing food. Nomadic mothers tended to stop breastfeeding their babies around three to four years of age [4]. Because a four-year-old human still cannot feed itself, the mother relied on the support of a broader community to help feed the child after weaning. This timeline is critical because breastfeeding suppresses ovulation, acting as nature’s birth control. A woman who is breastfeeding frequently has a lower chance of getting pregnant again, allowing her to successfully raise her child to maturity.
Ancient humans were aware of how weaning affected birth spacing. Mammalian males in general are a danger to the offspring of nursing mothers, because they know that a female will not be receptive to mating while she is nursing [5]. Prehistoric humans understood the consequences of early weaning: the population would grow.
These groups were deeply aware of the impact of a rapidly growing population. They had experienced overhunting and habitat destruction, recording those ecological limits in their
stories and collective memories. Early human populations also possessed an extensive knowledge of plant-based medicines to prevent or end pregnancies, such as acacia and silphium [6]. There was no reason for a community to intentionally trigger rapid population growth.
When humans stayed put, a mother had new options. She could supplement breastfeeding with porridge or mashed-up grain meal. Transitioning from foraging to agriculture significantly increased the daily hours of labor required to survive. Processing grain, weeding, and hauling water are continuous, physically exhausting tasks. While mothers can and do farm with infants, early weaning via grain porridge allowed a mother to conserve her physical energy. She could keep working in this system that demanded her labor following the planting cycles.
The capacity for rapid population growth was unlocked, and density surged. To keep feeding a denser population, people had to grow more of that easily harvested, easily processed food.
They needed more domesticated grain.
This required a shift in scale that fundamentally changed how humans impacted the land. An intact habitat functions as a biological loop. Above ground, it supports insects, amphibians, birds, and mammals. Below ground, networks of fungi, bacteria, and earthworms form a soil food web. Waste and dead organic matter are rapidly broken
down and cycled back into the system. The ecosystem maintains its own fertility. Mobile foraging populations existed within these systems at low densities, typically less than one person per square kilometer. A grain-based density could be 100 times that or more.
Farming breaks the biological loop on purpose. To make a farm, humans fence out wild animals, pull up competing plants, and pack the desired crops together tightly. When those packed plants grow, they extract what they need from the soil. But unlike a wild ecosystem, those plants do not die and rot where they stand. Humans harvest them, put them in carts, and transport them away. The nutrients are physically stripped from the land. To stop the earth from dying, early farmers had to haul fertility back. In the wild, animals deposit their waste where they eat, directly returning nutrients like phosphorus and nitrogen to the surface. Foragers move on before their own waste can make them sick. The living ecosystem rapidly breaks down the waste into more life.
Farming humans needed to find a way to bring nutrients back to the farms. If you gather enough human and animal waste to fertilize large agricultural fields, you either take your time and process it (i.e., composting), or you bring sickness with the nutrients. Piling up untreated waste where you live breeds parasites and waterborne disease.
Then there is the water. A densely packed field of crops often drinks far more water than naturally falls on it.
To keep the plants alive, humans had to drag water from rivers out to dry fields. That is what irrigation is: the brute-force movement of water. With trees cut down to make room for planting fields, the natural water recycling engine was gone.
Human hands then had to do its work. They hauled the waste, dug the canals, and pulled the weeds.
As populations became stationary and dependent on grains, their health declined. When bioarchaeologists examine skeletons from the Mediterranean before agriculture, they find mobile foragers who were robust, with men averaging five-foot-nine. After the shift to farming, average male height dropped to five-foot-three [7]. We see this baseline physical toll clearly in the Indus Valley.
Skeletons from this period show a reduction in stature, dental degradation from a carbohydrate-heavy diet, and markers of diseases caused by living in high densities.
Larger populations also meant more fights over territory. The Indus Valley civilizations had mountains to protect them from invasion. They also possessed abundant copper and tin ores located close together. Because these metals were widely available, many people knew how to forge bronze, a copper and tin alloy used to make the most advanced fighting tools at the time. This wide distribution of resources prevented any single group from establishing a monopoly on violence to dominate the region.
Their physical footprint reflects a society of equals.
Excavations at Mohenjo-Daro and Harappa reveal standardized baked-brick housing, with nearly every home featuring its own well and drainage system. The largest buildings in the city were a public facility known as the Great Bath, and the granaries for food storage. Their artifacts feature standardized weights for trade, terra-cotta toys, and seals depicting animals and nature. Archaeologists have never found carvings, reliefs, or monuments depicting mass warfare [8]. People in the Indus Valley appear to have voluntarily participated to gain access to grain storage, irrigation, and markets. Blessed with the gift of a flooding, nutrient-rich river as well, the population in the Indus Valley never came close to densities in the Nile Valley. There was no reason to pack as many people in as tightly as possible. And there was no one forcing them to do so anywhere. There is no archaeological evidence of an emperor, king, pharaoh, or ruling class of any kind in the roughly 2,000-year history of these civilizations [8].
This was not what happened in the vast majority of early civilizations.
In other regions, the materials required to make advanced weapons were scarce. A small group could control the supply. Once a group secured this monopoly on violence, they took the exact principles they had learned from domesticating plants and animals—fencing them in,
selective breeding, early weaning, and harvesting surplus—and applied them to other human beings. This marks the emergence of empires built on enslaved labor.
In anthropology, monumental architecture—such as Egyptian pyramids or Mesopotamian ziggurats—is understood not just as a building, but as a physical display of power that requires the deliberate diversion of human energy. Every hour a laborer spent digging, drying, transporting, and stacking mud bricks for a temple was an hour of caloric energy forcibly redirected away from growing food for their own family, rest, or play. The massive structure serves a specific cultural purpose: it provides a permanent, physical reminder of the ruling class’s supremacy and legitimizes the hierarchy [9].
To understand the scale of this extraction, we have to look at the skeletal remains of the laborers who built these monuments. Bioarchaeological evidence from the North Tombs Cemetery at Amarna in Egypt reveals the mortality rate of the laboring class. More than 90 percent of the skeletons in this worker cemetery belonged to individuals between the ages of 7 and 25. The teenagers show compressed vertebrae and spinal fractures from carrying standard limestone building blocks weighing over 150 pounds. Their skeletons exhibit scurvy and severe porotic hyperostosis—spongy lesions on the skull caused by malnutrition and anemia [10]. In early China, excavations of the Shang Dynasty royal city of Anyang reveal massive tombs surrounded by the mass graves of thousands of
laborers and field slaves who were either worked to death or sacrificed to serve the ruling class in the afterlife [11]. People did not look at that physical collapse and volunteer to join it.
As anthropologist James C. Scott summarizes the archaeological consensus: “There is no evidence that anyone voluntarily became a state subject.” [12] The extraction of materials required the same systemic redirection of calories. The Royal Cemetery of Ur in Mesopotamia contained tombs overflowing with gold and lapis lazuli. Lapis lazuli is not found in Mesopotamia; it had to be mined in the mountains of Afghanistan and transported over a thousand miles.
The Indus Valley redirected its surplus energy horizontally, investing in public baths, household wells, and municipal drainage. The early empires of Egypt, Mesopotamia, and China redirected their surplus energy vertically. The laboring classes under a hierarchy were worked to death before reaching full adulthood to build structures that served no biological purpose to the population [13].
Early enslavement agricultural states required concentrated populations to work, pay taxes, and supply conscripts.
Both hierarchically dominated and egalitarian agricultural civilizations produced shorter, sicker lives than mobile foraging. However, the physical damage to the human body under dominant hierarchies was starkly different from that in flat societies. In egalitarian centers like
Harappa, bioarchaeologists observe the expected baseline toll of early farming: worn joints from daily fieldwork, high rates of dental cavities from sticky, grain-based diets, and the presence of density-related infections. Yet, skeletal trauma from interpersonal violence was exceptionally rare during their peak urban phase, and mortality was distributed naturally across a normal lifespan [22].
In contrast, the bioarchaeological record of hierarchical states reveals institutionalized, forced physical abuse. In addition to the severe spinal compression found in Egyptian adolescents hauling stone, skeletons from state-level societies frequently exhibit “parry fractures”—broken forearms sustained when raising an arm to block a blow from a taskmaster, guard, or weapon. In Shang Dynasty China, the physical damage extended to systemic human sacrifice, with thousands of laborers ritually decapitated [11]. The skeletal record demonstrates that while farming universally degraded human health, ruling hierarchies weaponized that degradation to physically break the human body for expansion.
Geography determined where these states successfully formed, emerging most easily where productive agricultural land was surrounded by terrain that was difficult to survive in [14].
Egypt is the primary example. The Nile Valley provided a narrow agricultural corridor bounded by desert.
The river enabled dense farming, but the desert made it extremely difficult for a farming household to leave and
survive outside the state’s reach. Because exit was geographically blocked, rulers could impose heavy taxation and forced, unpaid labor without losing their workforce [15].
The Bible preserves what ancient people understood about Egypt: it was a slave state surrounded by a desert that limited escape.
When a group of slaves attempts to leave, they are told no and worked harder. After acts of divine intervention devastate the kingdom, the slaves are allowed to flee. The kingdom decides to follow the escaping slaves to slaughter them. More divine intervention saves them, and they escape into the desert, where they spend the next forty years wandering.
Where geography offered an exit, people took it.
Southern Mesopotamia contained productive rivers, but it also bordered marshes and open grasslands where people could fish, herd, and evade state control. In Southeast Asia, highland forests provided refuge from valley states. The presence of these refuge zones meant the state had to actively prevent its population from leaving [16].
This requirement produced the earliest administrative technologies. Sumerian clay tablets functioned as centralized ledgers where administrators recorded grain production, livestock, and people. The ledgers tracked field assignments and captured slaves, tracking human beings as property
alongside the grain. Scribes pressed marks into clay to count female slaves in the exact same format they used to count flocks of sheep. The Sumerian written symbol for a female slave literally combined the symbol for “woman” with the symbol for “mountain”—meaning a woman captured from the foreign hills [17].
To maintain this system, specialized classes formed.
A military class managed enforcement and capture. An administrative class managed the ledgers. Religious and political authority fused to justify the hierarchy [18]. To keep this inventory from walking away, rulers carved containment laws into stone. The Code of Hammurabi (c. 1750 BC) states clearly in Law 15: “If any one takes a male or female slave… outside the city gates, he shall be put to death.” Law 16 mandates: “If any one receives into his house a runaway male or female slave… he shall be put to death.” [19] The physical architecture of early cities reflected this need for containment. The walls built around early settlements protected against outside attacks, but they also functioned to keep the labor force inside [20]. When geography protected populations who fled, the state attacked the geography. History consistently shows states engineering projects to drain wetlands and clear forests that shelter populations living outside the system.
The early slave state did not grow because it was inherently attractive. It grew because it was an
administrative machine that required constant inputs of land and labor to maintain itself.
For the ruling class, expansion meant more power over human lives. An individual human has a biological limit on what they can consume, but a ruling class storing wealth in a vault is not under such a limit. More wealth simply means more ability to expand. A larger enslaved population means more concubines, cooks, gardeners, farmers, entertainers, craftsmen, miners, alchemists, engineers, soldiers, and priests at your disposal.
The phrase all roads lead to Rome does not describe travel; it describes a one-way extraction funnel. Roman road networks were engineered specifically to move armies outward and drain resources, goods, and wealth from the edges of the empire directly into the capital [21].
This mechanism exists in nature. A common biological equivalent is cancerous growth. In a healthy biological system, energy flows sustain the whole organism.
A cancer cell breaks this loop, redirecting the body’s energy flows strictly into its own growth and replication. It builds its own blood vessels to siphon nutrients from the host body, demanding continuous resources [22]. The empire is the macro-version of this biology. The hierarchy redirects energy flows of the society—its labor, its grain, its wealth—away from the health of the population. That energy is funneled to the ruling class, who then demand and direct it toward more conquest, prioritizing infinite growth until it inevitably kills the host.
Extract, Deplete, Expand, Repeat The earliest surviving work of written literature comes from Mesopotamia. Dating to roughly 2100 BC, the Epic of Gilgamesh tells the story of a king who decides to travel to the distant Cedar Forest. He wants to build massive city walls and monuments to secure everlasting fame for himself, and to bring glory to his people.
The forest is a vast wilderness protected by Humbaba, a guardian placed there by the chief god to deter humans from harming the forest. Upon arriving, Gilgamesh and his companion, Enkidu, immediately begin cutting down the massive cedars. Humbaba attacks to defend the trees, but Gilgamesh overpowers him. Pinned to the ground, the guardian attempts to negotiate, offering to serve the human king: “Let me go, Gilgamesh… The trees that I grew, I will cut down for you.” Enkidu advises Gilgamesh not to trust the guardian. “Gilgamesh heard the word of his companion. He took the axe in his hand, he drew the sword from his belt. Gilgamesh struck him on the neck…
Humbaba fell… Gilgamesh felled the trees, while Enkidu searched out the best timber.” [23]
With the protector dead, they clear-cut the sacred cedars, bind the timber into a massive raft, and float it down the Euphrates River to Uruk.
Long before the development of agriculture, humans had mined the earth for resources like obsidian, ochre, and flint. They transported these materials across hundreds of miles, returning to the same deposits for thousands of years [24]. Because early populations were small and used simple tools, the impact was limited.
The establishment of cities changed the scale. Cities needed clay and sand for brickmaking, stone for monuments, and massive amounts of charcoal to melt metals. As cities grew, their material demands grew with them. Cities rapidly burned through the resources immediately surrounding them.
By 2000 BC, the global human population was between 25 and 35 million [25]. The overwhelming majority were now engaged in farming or herding domesticated animals. Human activity had already pulled roughly one to two percent of the planet’s land entirely out of the wild—cleared, farmed, grazed, or built upon [26].
Gilgamesh came from the ancient civilization of Sumer, located in Mesopotamia (modern-day Iraq). To feed densely packed populations in the hot, dry climate, the empire relied heavily on irrigation—hauling water from rivers to dry fields. The local water contained small amounts of dissolved salt. When the fields were repeatedly flooded
under the hot sun, the water evaporated, but the salt was left behind in the soil. Year after year, the salt built up.
The civilization tracked this degradation in their clay tablets. Wheat is highly sensitive to salt in the dirt, whereas barley is much more tolerant. The tablets show a forced shift: fields that once grew wheat were converted entirely to barley just to keep producing food. By 3500 BC, wheat made up roughly 16 percent of the crop. By 2100 BC, it had dropped to 2 percent. By 1700 BC, wheat disappeared from the accounting records entirely [27]. Eventually, the rising salt levels killed the barley, too. Grain yields in affected parts of Sumer fell to roughly one-third of what they had been a thousand years earlier. As the dirt turned white with salt crusts, the fields were abandoned [28]. The Sumerian collapse demonstrated what happens when a society ignores the environmental impact of its activities. The land failed.
The logic of the hierarchical empire kept running in other places. The mechanism operated on a fixed loop: more land produced more food; more food supported more people; more people supplied larger armies; and larger armies seized more land. Two thousand years later, the Roman Empire was operating this system at a continental scale. By the first and second centuries AD, the global population had grown to somewhere between 170 and 300 million [29]. Five to ten percent of the Earth’s land had been transformed into human habitats. Wetlands were drained, native pastures were grazed bare, and rivers were diverted [30].
The physical damage to the land was obvious to the people living within the system. Writing in Greece around 360 BC, Plato documented a landscape that had already passed the point of return. He noted that in his grandfather’s time, the hills were covered in deep soil and thick forests. After generations of clear-cutting and overgrazing, the topsoil had mostly washed away. Plato described the surviving land exactly as he saw it: “What now remains compared with what then existed is like the skeleton of a sick man, all the fat and soft earth having wasted away, and only the bare framework of the land being left.” [31] Rome expanded this depletion across Europe and North Africa. The empire’s silver mines in Spain were worked by tens of thousands of enslaved people simultaneously, using high-pressure water to wash entire mountainsides away to reach the ore [32].
The Roman capital was fed by massive annual shipments of Egyptian grain, grown by populations trapped by the surrounding desert and forced to pay taxes in food [33]. The scale of Rome’s extraction remains visible in the Arctic ice. To melt silver and lead for its coins and pipes, the empire burned staggering amounts of wood in massive furnaces. When scientists drill deep into the ice sheets of Greenland, they find an unnatural spike in lead pollution that perfectly tracks the rise of the Roman Republic. The pollution stays in the ice for centuries. When the empire collapsed and the furnaces stopped burning, the lead levels crashed [34].
As enormous as its impact was, the Roman Empire was ultimately limited by its energy. Roughly half the work in the ancient world was done by human muscle, most of it formally enslaved people. Animals forced into labor contributed another twenty to thirty percent, and burning wood powered the rest [35]. The future world would not be under the same limitations.
Around the year 1800, the global human population reached one billion. As we showed in Chapter 2, the earth could likely sustain 40 to 170 million humans without agriculture. Empires spent thousands of years reshaping the planet’s surface to produce food at a scale nature does not to pass that one-billion-person mark. This reshaping was globally visible. Fifteen to twenty percent of the Earth’s land had been converted to human use. Over 700 million hectares of native forest had been removed—roughly ten to fifteen percent of the total forest cover that existed at the start of the Holocene [36]. Global trade networks connected distant lands into a single economic system, where the price of goods in European capitals directly dictated whether a forest in India was cleared or left standing.
The physical limit on the system’s expansion was finally broken when humans began digging up deep, buried energy. Coal and oil are stored energy—millions of years of ancient sunlight, captured by plants, and compressed by the earth’s pressure into a dense fuel. When a barrel of fuel is
burned, it releases heat that took the planet an almost incomprehensible amount of time to store.
Fossil fuels did not create a new economic model.
They gave the old system a new kind of worker. This stored energy never tired, did not need to eat farm crops, and could not rebel. The logic remained the same: capture work, extract surplus, and expand. The waste from this rapidly expanding industrial system immediately began changing the water and the air. Industrial cities dumped heavy metals, coal byproducts, and raw human waste directly into rivers.
In the summer of 1858, the River Thames became so foul that the physical stench disrupted the British government.
Lawmakers had to soak the curtains of Parliament in chloride of lime simply to remain in the building [37].
The physical expansion required the destruction of wild habitats to make room for more agriculture. The great prairies of North America—complex environments that took millions of years to stabilize—were plowed under within a few generations. The native bison herds, which had numbered between 30 and 60 million animals, were intentionally wiped out to clear the land for farming and starve out the indigenous people. By 1889, fewer than 600 wild bison remained [38].
Despite this massive land expansion, farming was hitting a biological wall. In the natural world, plant growth is strictly limited by the availability of nitrogen. For thousands of years, the only way to return nitrogen to the soil was biological: farmers had to rest the field, plant
nitrogen-fixing legumes, or apply animal waste. This biological rest phase served as a hard physical speed limit on agricultural extraction. The economic system viewed this limit as an existential threat. In an 1898 address to the British Association for the Advancement of Science, Sir William Crookes warned that global wheat yields were approaching a hard ceiling, declaring: “It is the chemist who must come to the rescue of the threatened communities. It is through the laboratory that starvation may ultimately be turned into plenty.” [39] In 1909, German chemists Fritz Haber and Carl Bosch broke the limit. They developed an industrial process to pull nitrogen directly out of the atmosphere and convert it into synthetic ammonia. The breakthrough was globally celebrated as a miracle—the ability to make “bread from air.” The nitrogen did not come from nothing. The Haber-Bosch process requires extreme heat and pressure, consuming massive amounts of energy. It also relies on hydrogen, which is stripped directly from fossil fuels like natural gas. By turning fossil fuels into synthetic fertilizer, the system created a dangerous illusion. Because they had bypassed the nitrogen bottleneck, agricultural administrators assumed they had conquered the biological limits of the soil entirely. They no longer needed to rest the land. With the limits of human muscle and soil nitrogen removed, the consequences accelerated.
Where native forests were not entirely cleared for this booming agriculture, they were permanently cut into
pieces by roads, railways, and fences. The passenger pigeon, which had numbered in the billions within living memory, was driven extinct by 1914. While commercial hunting reduced their numbers, the population collapsed completely because the system clear-cut the massive, unbroken forests the birds required to nest together in massive groups [40].
Soon, oil joined coal as a primary fuel. A single barrel of crude oil contains the energy equivalent of roughly four to five years of continuous, hard manual labor by a human. By 1927, the world was consuming approximately 1.2 billion barrels of oil per year. Alongside this, coal consumption added the energy equivalent of another three to four billion barrels [41]. Combined, burning fossil fuels added the working power of 10 to 20 billion humans to the system every year.
The global population, which had taken the entirety of human history to reach one billion, doubled to two billion in just 123 years, crossing the threshold in 1927.
By this time, thirty to thirty-five percent of the Earth’s land had been converted to agriculture or grazing [42].
For the first time, human activity was measurably altering the makeup of the air itself. Before industrialization, the atmosphere held a concentration of roughly 280 parts per million of carbon dioxide—a level that had remained highly stable since the beginning of the Holocene [43]. By 1927, burning stored energy had pushed that number past 306 ppm [43]. Carbon dioxide is one of the major greenhouse gases that is heating up the planet.
The physical limits of the soil were tested at the exact same time. On the American Great Plains, native prairie grasses had held the dry topsoil in place for thousands of years. Their root systems went six feet deep, binding the earth even through high winds. When mechanized farming arrived, the deep native roots were plowed under to plant fields of wheat [44].
When a multi-year drought struck in the 1930s, the soil could not hold together. Without the native roots, the exposed topsoil simply blew away. In May 1934, a single storm lifted an estimated 300 million tons of topsoil, carrying it across the continent and dropping dust onto the eastern seaboard. The physical collapse of the farmland forced 3.5 million people to abandon their homes [45].
Agricultural pioneers watched this chemical transition with alarm. In 1940, Sir Albert Howard, one of the founders of the organic movement, warned that the system had fallen victim to an “NPK mentality” (referring to Nitrogen, Phosphorus, and Potassium). Howard wrote that the system was making an error by treating the soil as a factory machine rather than a living organism: “The entire mystery of soil fertility had been solved… Since treating the soil as a machine seemed to work well enough, at least in the short term, there no longer seemed any need to worry about such quaint things as earthworms and humus.” [46] In reality, forcing the earth to produce massive, continuous crop yields without biological rest rapidly accelerated the depletion of the soil’s entire profile. Because
the crops were forced to grow faster and larger, they aggressively drained the earth of dozens of essential trace minerals and micronutrients. The system attempted to patch this depletion by strip-mining phosphorus and potassium to apply synthetically alongside the nitrogen, reinforcing the exact mentality Howard warned about, while the broader biological complexity of the soil collapsed.
More critically, pumping synthetic chemicals onto continuous monoculture crops burned through the soil’s organic carbon. The living microbiome of the earth starved.
The soil lost its physical structure and its natural ability to absorb water. It degraded from a self-sustaining biological loop into an inert, physical sponge whose only remaining function was to hold fossil-fuel chemicals just long enough for the crop roots to absorb them. The trajectory of the system was set.
The alternatives to endless growth had been forgotten. The empires were operating as if they could, and should, turn the entire planet into ever expanding farms and pavement.
Terminal Growth In 1927, the global human population reached two billion.
It had taken the entirety of human history to reach that number. It took less than one hundred years to quadruple it to eight billion.
The energy required to support this expansion grew at the same pace. In 1924, the global economy consumed roughly 2.8 million barrels of oil per day. One century later, that number crossed 102 million barrels per day—a nearly thirty-six-fold increase [47]. The system did not move away from older fuels to achieve this. The burning of coal and natural gas hit historic highs at the same time. Renewable energy infrastructure like solar and wind expanded faster than at any point in history, but they did not replace fossil fuels. They were added on top of them to meet the demand for growth [48]. This stored energy allowed the system to alter the physical crust of the Earth. By the 2020s, the global economy was extracting roughly 106 billion metric tons of material from the planet every single year [49]. To picture that physical mass: the Great Pyramid of Giza weighs an estimated six million tons. The modern economic machine digs up, processes, and moves the weight of more than seventeen thousand Great Pyramids annually.
Nearly half of that annual weight is sand and gravel, dug up to mix concrete and pave the planet’s surface.
Because land-based sand deposits have been heavily drained, the system now dredges the ocean floor to keep up the supply, systematically destroying the living ecosystems at the bottom of the sea in the process [50].
The shift to a digital, service-based economy did not separate this growth from the physical world. The internet requires immense physical resources. By 2024, global data centers consumed massive amounts of industrial
electricity—over 400 terawatt-hours annually. Because these sprawling warehouses of computer servers generate extreme heat, they require constant liquid cooling. An average data center evaporates hundreds of thousands of gallons of freshwater every day. Driven by the massive processing power required for artificial intelligence, the digital sector’s cooling demands are projected to require over a trillion liters of freshwater every year by the end of the decade [51].
The draining of fresh water is planetary in scale. As surface rivers were diverted or polluted by industrial waste, the agricultural system began drilling into underground aquifers. These deep, subterranean water reserves took thousands of years to accumulate. Between 1993 and 2010 alone, the system pumped over two trillion tons of this groundwater to the surface. The physical weight of the water moved from beneath the continents into the oceans was so immense that it measurably shifted the Earth’s rotational axis, tilting the planet roughly eighty centimeters [52].
The soil above those aquifers is being mined just as aggressively. Driven by the continuous dumping of synthetic chemicals and the use of heavy machinery, the Earth’s agricultural topsoil is currently washing or blowing away between one hundred and one thousand times faster than the natural rate at which it forms [53].
The destruction of the physical earth directly dictates the collapse of the biological web. An ecosystem is not a collection of individual animals; it is a highly
connected engine of energy transfer. When the physical foundation is removed, the life it supports is wiped out.
In the last thirty years, 420 million hectares of native forest have been cleared [54]. In the Amazon, roughly twenty percent of the total forest has been removed, and another seventeen percent is heavily damaged [55]. Because the Amazon generates its own rainfall by pulling moisture from the ground and sweating it into the air, physically removing the trees breaks the water cycle. The forest begins to dry out from the inside, triggering massive fires that start on their own and clear more land without any human involvement.
As the natural habitats are paved, plowed, or burned, the populations of the animals living within them collapse. In the fifty years between 1970 and 2020, monitored populations of wild animals with backbones—mammals, birds, amphibians, reptiles, and fish—declined by an average of 73 percent globally. That drop is from the already depleted baseline of 1970. In Latin America and the Caribbean, those tracked wildlife populations fell by 95 percent [56].
The wipeout extends into the oceans. The oceans absorb roughly a quarter of the carbon dioxide pollution created by the fossil fuel economy. This changes the chemistry of the water, making it more acidic. The oceans also absorb over ninety percent of the excess heat trapped in the atmosphere. The combination of heat stress and acidic
water has killed roughly half of all living coral reefs since the 1950s [57].
The massive scale of this extinction means there is no longer an “outside” to the economic model. Even in untouched wilderness areas entirely free from plows, bulldozers, or pesticides, the base of the food web is failing.
In a remote, protected mountain meadow in Colorado, researchers tracking flying insects over two decades recorded a 72 percent collapse in the population. The cause was a general rise in summer temperatures driven by air pollution generated thousands of miles away [58].
Insects pollinate three-quarters of the human food supply and form the foundational food base for the rest of the animal kingdom. Globally, insect populations have dropped by an estimated 45 percent over forty years [59].
The waste generated by this 106-billion-ton annual extraction cycle infects what remains of the living world.
Chemical leftovers from oil refining are turned into plastics, a material that does not break down naturally. Since the 1950s, plastic production has grown by a factor of over two hundred. The material has shattered into microscopic pieces and entered the planetary water cycle. It is now heavily concentrated in the soil, in the deepest ocean trenches, and in the flesh of the animals at the top of the food chain. It is consistently detected in human blood, lung tissue, and the placenta of developing fetuses [60].
The distribution of this waste reveals the underlying structure of the system. Wealthy, highly
industrialized nations generate the majority of the material consumption and chemical waste. A significant percentage of this waste, including toxic electronic components and non-recyclable plastics, is shipped to poorer nations that lack the facilities to safely process it.
The economic reward of this 106-billion-ton extraction does not distribute evenly; it pools at the top. By 2026, global billionaire wealth had surged to historic highs.
A small group of just twelve individuals now controls the exact same amount of wealth as the bottom half of humanity combined—roughly 4.1 billion people [61].
To manage the populations entirely excluded from this wealth, the system relies on physical containment.
Globally, there are over 11.7 million humans currently held in cages [62]. In the United States alone, roughly 1.9 million people are in cages. The Thirteenth Amendment of the US Constitution abolished slavery, but explicitly kept it “as a punishment for crime whereof the party shall have been duly convicted.” Under this legal exception, people in prison are stripped of workplace protections and forced to labor under the threat of solitary confinement, producing billions of dollars in goods and services for pennies an hour, or entirely for free [63].
For the populations outside the cages, the economic machine extracts their physical health and their time. A 2023 report by the International Labour Organization revealed that 2.93 million workers die every single year as a direct result of work-related
factors—equivalent to roughly 8,000 human beings killed by their jobs every day [64].
The vast majority of these deaths are not sudden accidents, but slow biological extraction. A 2018 United Nations human rights report documented the catastrophic toll of the system’s chemical footprint, stating bluntly: “One worker dies at least every 30 seconds from exposure to toxic industrial chemicals, pesticides, dust, radiation, and other hazardous substances.” [65] The physical realities of this extraction are staggering. To satisfy the global demand for cheap steel, the massive, thirty-year-old cargo ships of the global supply chain are intentionally run aground on the beaches of Bangladesh. There, workers break the toxic ships apart by hand, using gas torches without meaningful protection.
They suffocate from poisonous gas trapped in the ship chambers or are crushed by falling steel plates so massive that locals refer to the impacts as “earthquakes.” [66] In the sewers of India, informal sanitation workers descend into total darkness to manually clear human waste.
The World Health Organization estimates that one sanitation worker dies every five days in these sewers, suffocating from lethal gases because they are not provided with protective breathing equipment [67].
Even the “clean” digital economy is built on a foundation of human extraction. The smartphones and electric vehicles of the modern era are powered by batteries that require cobalt. Roughly 75 percent of the world’s
cobalt is dug out of the Democratic Republic of the Congo.
Hundreds of thousands of informal miners, including tens of thousands of children as young as seven, dig this metal out of the earth by hand, breathing toxic dust that causes severe lung disease and birth defects. In his investigation of the supply chain, researcher Siddharth Kara documented the physical reality of the mines, quoting a Congolese worker: “We work in our graves… Please tell the people in your country, a child in the Congo dies every day so that they can plug in their phones.” [68] When the digital hardware is finally assembled, the extraction shifts to the psychological limits of the workers.
In 2010, the grueling, twelve-hour shifts and hyper-controlled environments at the Foxconn manufacturing plants in China led to a wave of worker suicides, with over a dozen employees jumping to their deaths from the factory rooftops. The system’s response was not to change the economic demands of the assembly line.
The company simply built large nets around the outside of the factory to catch the falling bodies, and temporarily forced workers to sign pledges promising not to kill themselves [69].
This extraction translates directly into biological time. A child born at the top of the global economic pyramid can expect to live significantly longer than one born at the bottom. The World Health Organization documents a 33-year gap in life expectancy based simply on the country in which a human is born [70]. Even within the wealthiest
nations, the divide is stark. In the United States, men in the top one percent of income live an average of fifteen years longer than men in the bottom one percent, whose life expectancies mirror those in poorer nations like Sudan and Pakistan [71].
When archaeologists excavate the skeletal remains of the Roman Empire, they do not need to look at written records to find the inequality; they look at the bones. The skeletons of the laboring classes show extreme rates of linear enamel hypoplasia—permanent horizontal grooves carved into their teeth caused by severe childhood starvation and stress. Their spines and joints show severe bone breakdown from relentless heavy labor [72].
The modern empire does the same thing.
According to 2024 data from the World Health Organization, over 148 million children under the age of five—nearly a quarter of all children on Earth—are currently physically stunted by chronic malnutrition [73].
Their skeletal and neurological growth is permanently arrested by an economic model that extracts agricultural wealth from their regions while leaving them undernourished.
For those who enter the labor force, the physical extraction continues. Across the sugarcane fields of Central America, an epidemic of chronic kidney disease has killed tens of thousands of young agricultural workers [74].
Epidemiological research confirms the primary driver is occupational heat stress and dehydration—kidneys systematically failing under the demands of heavy manual labor in hot environments. At the other end of the supply chain, in the informal e-waste yards where the hardware of the digital economy is dismantled by hand, workers absorb extreme levels of cadmium and lead. Cadmium toxicity specifically targets the skeletal system, leaching calcium and causing the workers’ bones to physically demineralize [75].
The economic machine carves its hierarchy directly into the bone density, stunted growth, chronic illness, and shortened lifespans of the global poor. The modern capitalist system did not emerge from a vacuum. It is a continuation of an ancient system of extraction.
Thousands of years ago, the Indus Valley civilization built vast, organized cities across modern-day Pakistan and northwest India. They engineered complex city-wide plumbing systems, standardized their weights and measures for trade, and managed densely packed urban populations for centuries. Yet archaeologists have found no monuments to divine kings, no sprawling palaces, and no evidence of the massive wealth divides and aggressive military expansions that defined other empires of their time [76]. They proved that large, highly organized human societies do not inherently require a rigid, extractive hierarchy.
The modern economic system did not inherit the ideology of the Indus Valley. It is the direct descendant of
Mesopotamia, of the Egyptian pharaohs, and of the Roman Senate. It inherited the belief that the natural world is a warehouse of raw materials waiting to be turned into wealth, and that human beings are units of labor meant to fuel that conversion. The core logic has not changed in five thousand years. Modern capitalism remodeled ancient empire ideology and scaled it across the entire planet.
In 2026, every nation on the planet set a goal for more consumption, more economic growth, and more people.
