Classical Sources
The Roman agricultural writers gave us 2,000-year-old operating manuals for running a household on muscle, wood, and water. Their knowledge is not museum material. It is practical knowledge from a civilization that ran on the energy basis we will return to.
Marcus Porcius Cato (Cato the Elder), De Agri Cultura (c. 160 BCE)
The oldest surviving Latin prose work. A farm management manual covering crop rotation, green manure, soil testing, seed saving, food preservation, manure management, and the Roman farm contract (lex locationis). Cato's instructions are observational, local, and free. No laboratory required. No expert required.
Marcus Terentius Varro, Rerum Rusticarum (37 BCE)
A three-book dialogue on Roman agriculture covering farm size and productivity (smallholdings outproduce latifundia per acre), animal husbandry, beekeeping, rainwater collection, manure types and applications, and the Roman household as productive unit. Varro's data on small-farm productivity has been confirmed by modern research.
Lucius Junius Moderatus Columella, De Re Rustica (c. 60 CE)
Twelve books on Roman agriculture. Columella devoted an entire book to the vilicus (farm manager) and insisted no one can manage land well from a distance. He warned that neglecting soil for a single season shows damage for three. His ideal farm compound includes press room, granary, stable, poultry yard, vegetable garden, and orchard, all within the same enclosure. The original retrosuburbia.
Pliny the Elder, Naturalis Historia (77 CE)
Thirty-seven books compiling the known natural knowledge of the Roman world, including agriculture, botany, soil science, and food preservation. Pliny records underground grain storage, soil classification, and the practical agricultural knowledge of Gauls, Greeks, and other peoples Rome encountered.
Modern Thinkers
These are the people whose frameworks, data, and arguments shaped the book's analysis of civilization, energy, ecology, and alternatives.
William R. Catton Jr., Overshoot: The Ecological Basis of Revolutionary Change (1980)
Catton coined the term "Homo colossus" to describe what fossil fuels made: a new creature ecologically distinct from pre-industrial humans, with a linear metabolism that extracts, uses, and discards at rates exceeding replenishment. He drew on ecology, population biology, and the concept of carrying capacity to argue that industrial civilization is a self-terminating system. The concept of Homo colossus and the arc of overshoot are central to this book.
John Michael Greer, The Long Descent (2008) and The Ecotechnic Future (2009)
Greer's concept of catabolic collapse, the process by which the technosphere cannibalizes its own infrastructure in a stair-step decline of "one step forward, two steps back," is drawn on throughout this book. His framework rejects both sudden apocalypse and gradual transition, predicting a prolonged, uneven descent with increasing hardship and decreasing complexity.
Nate Hagens, The Great Simplification (ongoing)
Hagens' work on energy return on investment (EROEI), the concept of "energy slaves," and the thermodynamic impossibility of substituting renewables for fossil fuels at current scale informs the book's analysis of energy descent. His framework that 150 energy slaves work for every American, and that this subsidy is temporary, is central to Saying #2.
Daniel Everett, Don't Sleep, There Are Snakes (2008) and Language: The Cultural Tool (2012)
Everett's work with the Pirahã people of the Amazon demonstrated a culture that values knowledge only insofar as it changes what you do tomorrow. Their epistemology, immediate experience, practical application, no speculation about distant possibilities, is the model for the attention pragmatism framework in Saying #144.
Donella Meadows, Dennis Meadows, Jørgen Randers, and William Behrens III, The Limits to Growth (1972)
The MIT study that modeled civilizational trajectories under different assumptions about population, industrial output, food, resources, and pollution. The "standard run" scenario, in which the system overshoots and collapses, has tracked closely with observed data for 50 years. The book's framework of civilizational trajectories informed by limits modeling is foundational to this book's analysis.
Joseph Tainter, The Collapse of Complex Societies (1988)
Tainter's argument that societies collapse when the marginal cost of maintaining complexity exceeds the marginal benefit, and that collapse is not catastrophe but simplification, informs the book's analysis of why reform is structurally impossible and why building simpler alternatives is the rational response.
Vandana Shiva, Staying Alive (1989) and subsequent works
Shiva's framework of monoculture of the mind, the violence of reductionist science, and the productivity of small diverse farms versus industrial monocultures informs the book's critique of industrial agriculture and its argument for bioregional, agroecological alternatives.
Miguel Altieri, Agroecology: The Science of Sustainable Agriculture (1987) and subsequent works
Altieri's research demonstrating that small, diverse, polycultural farms produce more food per unit of land than industrial monocultures, and that agroecology is a science with its own methodology (observation, local knowledge, ecological design), not a romantic return to pre-modern farming.
Hazel Henderson, Creating Alternative Futures (1978) and subsequent works
Henderson's critique of GDP as a measure of progress, her framework for alternative economic indicators, and her advocacy for local, diverse, sustainable economies inform the book's critique of growth economics and its argument for measuring what matters.

YouTube Channels
These channels provided the analytical frameworks, empirical claims, and lived practice that shaped the book's arguments. Research involved full transcript analysis, claim verification, and thematic synthesis.
Our Crises in Context (Andrea)
A systems-level analysis of civilizational overshoot, energy descent, and ecological collapse. The channel's core argument, that industrial civilization is a self-termining system because the processes that define it (extract, exploit, expand, exhaust, expire) inevitably destroy the ecological conditions they depend on, is the single most important analytical influence on this book. Key frameworks drawn from OCIC include:
The E5E process (Extract-Exploit-Expand-Exhaust-Expire): the self-reinforcing cycle that defines civilization's metabolism. Sayings #143 and #146.
Homo colossus: civilized humans as a distinct ecological entity with a linear metabolism. Drawing on Catton's concept and extending it into a naturalist's safari. Saying #142.
Catabolic collapse (from Greer): stair-step decline, not sudden apocalypse. Saying #146.
Attention pragmatism: a personal philosophy for information consumption in polycrisis, drawing on Pirahã epistemology. Saying #144.
Civili-zealotry: the irrational belief that civilization can be reformed into something benign. Saying #127.
Intimate collapse: applying collapse awareness to marriage, parenthood, and relationships. Saying #145.
The gwrm: a practical resilience-planning tool for systematically replacing industrial dependencies.

Episodes Analyzed
Planet Critical (Rachel Donald)
Climate corruption journalism and deep interviews with ecologists, economists, energy analysts, and indigenous scholars. Key themes drawn from Planet Critical include: the progress myth is 5,000-year-old propaganda; human needs are finite and satisfiable (Steinberger, Max-Neef); public services deliver more well-being per energy unit than GDP growth; coercive overconsumption is structural, not individual choice; extraction follows coloniality; degrowth with well-being is data-supported; and narrative/identity are the real battlefield. Full episode-by-episode analysis available covering 127+ episodes.
Research on food system fragility, supply chain collapse, and the fossil fuel dependency of industrial agriculture. Subtitle transcripts analyzed from ~35 videos covering seed sovereignty, soil depletion, supply chain vulnerability, and preservation technologies.
Indigenous & Traditional Knowledge
Knowledge systems that predate and outlast industrial civilization. These are not sources to be cited and set aside; they are operating systems that have been tested across millennia.
Haudenosaunee (Iroquois) Confederacy
The seven-generation decision-making framework: will this decision benefit people seven generations from now? If the answer is no, find a different decision. If the answer is "we can't know," slow down. The confederacy's co-governance structure, with women's councils holding accountability authority, informed the book's governance arguments.
Pirahã People (Amazonian Brazil)
An Amazonian people whose epistemology values knowledge only insofar as it changes what you do tomorrow. No speculation about distant possibilities. No storage of information for its own sake. Attention to the present, the useful, and the directly experienced. The model for attention pragmatism in Saying #144. Documented by Daniel Everett.
Mondragon Cooperative Corporation (Basque Country, Spain)
A network of worker cooperatives that has lasted 70+ years, demonstrating that democratic ownership and governance can operate at industrial scale. Cited as evidence that alternative institutions can be built and can last. Not a utopia, but a proof of concept.
La Via Campesina
The international peasants' movement, representing 200 million farmers across 80+ countries. Advocates for food sovereignty, agroecology, and peasant rights. Evidence that the alternative is already being built at global scale by the people who actually grow the food.
Movimento dos Trabalhadores Rurais Sem Terra (MST, Brazil)
The Landless Workers' Movement of Brazil, 40+ years of land reclamation, cooperative farming, and community building. Evidence that direct action on land access produces lasting results when paired with institution building.
Pancoger (Colombian campesino polyculture)
Traditional subsistence polyculture farming practiced by Colombian campesinos. Evidence that place-based, small-scale, diverse agriculture produces more food per unit land than industrial monoculture while regenerating soil.
Preservation & Agricultural Research
Practical knowledge for food sovereignty and low-energy food preservation, drawn from historical and contemporary sources.
Loop Farmstead Preservation Research
Original research into brine percentages, lacto-fermentation science, and preservation technologies that operate without electricity. Covering canning, drying, freezing, root cellaring, seed saving, smoking/curing, and fermentation in buckets, with specific brine concentration data for pickling across multiple cultural traditions. loopfarmstead.com/preservation
Soil Science & Erosion Data
Soil erosion outpaces soil formation by approximately 5:1 under industrial agriculture (Pimentel & Pimentel, 2003). This single data point underpins the book's argument that industrial agriculture is consuming its own foundation faster than it regenerates.
Permaculture & Design
Bill Mollison & David Holmgren, Permaculture One (1978) and subsequent works
The foundational permaculture design system: observe, pattern, integrate, close the loop. The design principles, catch and store energy, obtain a yield, use and value the marginal, integrate rather than segregate, are operating instructions for a planet that runs on sunlight. Cited explicitly in Saying #8 and implicitly throughout.
Toby Hemenway, Gaia's Garden (2001) and The Permaculture City (2015)
Accessible permaculture design for home-scale and community-scale. Hemenway's framework of zones, sectors, and stacking functions informed the book's arguments about retrofitting suburbs for productivity.
Additional Influences
Works and movements that shaped the book's perspective, even where not directly cited.
The Dark Mountain Project
A network of writers, artists, and thinkers who have stopped believing the stories our civilization tells about itself. The Uncivilisation manifesto (2009) and subsequent publications shaped the book's willingness to face ecological collapse without retreating into either techno-optimism or passive despair.
Transition Towns Movement
Community-led responses to peak oil, climate change, and economic contraction. The transition model of building local resilience from the ground up informed the book's practical arguments about what to do while the system winds down.
Solarpunk Movement
A cultural movement imagining and building sustainable, just, and beautiful futures. The book draws on solarpunk's vision while critiquing any solarpunk that assumes industrial infrastructure can simply be "greened" without rethinking scale, centralization, and extraction. Meaningful solarpunk must be low-energy, decentralized, and ecologically integrated.
Clara E. Mattei, The Capital Order: How Economists Invented Austerity and Paved the Way to Fascism (2022)
Mattei's historical analysis of how austerity was invented as a class discipline tool, not an economic necessity, informs the book's argument that economic "necessity" is often constructed to preserve existing power structures.
David Graeber, Debt: The First 5,000 Years (2011)
Graeber's anthropological history of debt demonstrates that the moral framing of debt obligation is a political choice, not an economic law. Informs the book's arguments about coercive systems and manufactured dependency.
