Beneath the surface lies a complex, bustling metropolis known as the Underground Community. Within the ecosystem, carbon functions as a vital chemical element while serving as the literal structural currency and physical infrastructure that sustains the resilient life systems of the modern world.
A History of Confusion: The Carbon Crisis is Simply a Matter of Balance
For decades, an excessive atmospheric overload of carbon generated widespread confusion; the imbalance pulled attention away from the essential role the element plays when properly balanced within the earth. Society frequently struggles with a fundamental paradox regarding how carbon can be mischaracterized as an environmental threat yet it is the primary chemical building block of all life on Earth.
The roots of confusion run deep, and decades ago Earth Impact (Ei) took a leadership role in demystifying public perception of carbon as a "bad" player in earthly matters.
As Ei closed the Era of Recycling Refinement in 2017 and entered the Era of Regeneration, the foundational RiA Magazine article, Carbon Crisis: Simply a Matter of Balance, published. The article features The Soil Story, a four-minute video that succinctly explains how carbon is simply out of balance between the five carbon pools. ... and how soil is the solution to the current carbon crisis.
According to global research syntheses maintained by the National Oceanic and Atmospheric Administration the planetary carbon cycle maintains equilibrium between five distinct pools: the Atmosphere, the Oceans, the Soils, the Biosphere, and the Fossil Pool.

Simultaneously, conventional industrial agriculture and urban landscape practices break open the soil matrix, releasing ancient subterranean carbon reserves into the atmosphere.
The solution does not require complex, synthetic engineering. To restore balance, excess atmospheric carbon must transfer back into the soil pools. Nature already designed the ultimate mechanism for the transfer: plant photosynthesis.
Earth’s Digestive System: The Biological Paradigm
To understand how soil stabilizes planetary systems, society must shift its perspective from chemistry to biology. Ei introduces the Earth’s Digestive System (EDS) framework to treat soil microbiology as a living digestive organism. Just as the human gut requires a balanced microbiome to process nutrients and sustain health, the soil requires a thriving subterranean microbiome to function.
For decades, conventional landscape and agricultural practices relied on synthetic chemical interventions that temporarily feed plants while disabling the natural soil ecosystems designed to sustain them. The EDS framework advocates for a transition to biological governance, ensuring the subterranean microbiome receives the structural support and nourishment necessary to manage water, cycle nutrients, and sustain life.
The RiA Magazine article, Earth’s Digestive System: Restoring the Soil Microbiome, introduces the EDS as new Ei focus area within the Nature Prevails platform.
A Pending Crisis: The Threat to Food and Oxygen (1)

A dangerous dilemma brews with an increasing global population and a diminishing ability to produce food.
In addition, plankton perishes at alarming rates due to ocean acidification and warmer water temperatures. Marine plant life—including phytoplankton, kelp, and algal plankton—uses photosynthesis to convert carbon dioxide and sunlight into sugars for energy, generating the vast majority of atmospheric oxygen.
The December 2015 Science Daily article, Failing phytoplankton, failing oxygen: Global warming disaster could suffocate life on planet Earth, states:
"About two-thirds of the planet's total atmospheric oxygen is produced by ocean phytoplankton -- and therefore cessation would result in the depletion of atmospheric oxygen on a global scale. This would likely result in the mass mortality of animals and humans."
Is sustainability enough to stave off the building crisis of a diminishing food and oxygen supply?

Urban Carbon Sinks: Rebuilding Land-Based Infrastructure
Traditionally, discussions surrounding carbon drawdown focused primarily on vast rural farmlands and remote agricultural rangelands. Yet, Ei recognized available solutions within urban landscapes and other developed areas. In 2020, Ei introduced a vital focus area via the RiA Magazine article, Urban Carbon Sinks: a regenerative solution to the diminishing oxygen-supply crisis.
Simply defined, a carbon sink is any area of land where plants draw down more carbon from the atmosphere via photosynthesis than the soil releases back into the atmosphere.
The oceans technically function as carbon sinks because marine systems currently absorb more atmospheric carbon than they release. However, excess carbon in the oceans causes ocean acidification that kills plankton at alarming rates. Restoring the balance requires a collaborative approach between land and sea, where terrestrial systems alleviate the pressure on marine ecosystems.

Urban landscapes—including corporate complexes, college campuses, highway medians, parks, and residential neighborhoods—represent millions of acres of underutilized land. Transitioning developed spaces from high-maintenance lawns to thriving urban carbon sinks transforms fragmented impervious surfaces and turfgrass into high-functioning biological infrastructure.
Rewilding Urban Landscapes
Rewilding urban land restores the natural ecosystems that evolved over thousands of years. The process requires the restoration of native plants and cultivates food for indigenous insects. Strong insect populations form the foundation for restoring healthy predator-prey hierarchies that thrived prior to urban development; with a restored insect population wildlife may flourish within the constructs of human development.
Inherent within rewilding urban landscapes are three primary benefits:
- Restoration of vibrant soil ecosystems.
- Drawdown of carbon from the atmosphere into the soils via plant photosynthesis.
- Establishment of food-secure neighborhoods within a community.

With more than 40 million acres of lawn nationwide, tremendous potential exists to reverse the diminishing food and oxygen crisis simply by rewilding lawns.
The 2020 RiA Magazine article, Urban Carbon Sinks: Rewilding Urban Landscapes, explains how solutions to the out-of-balance carbon scenario become available by overhauling current landscape-maintenance practices.
Upon relocating to her hometown of Sarasota, Florida, in 2021, Ei Founder & CEO Holly Elmore donated her front yard for an Ei Native Plant Landscape Pilot and her backyard for an Ei Permaculture-Oriented Landscape Pilot. The Holly Elmore Images (HEI) Ei Rewilding Urban Landscapes Pilots album chronicles pilot development and physical progress.
The accompanying RiA Magazine article, Ei Rewilding Urban Landscapes Pilots, formally announces the projects and emphasizes vital importance within the overarching Ei Nature Prevails platform.
The Biological Currency of the Underground Community
The entire subterranean economy begins with a solar-powered transaction. Through photosynthesis, plants capture atmospheric carbon and convert it into liquid carbon sugars. While some of sugars fuel plant growth above ground, a massive percentage is deliberately pumped down through roots and into the soil.
The process is not a leak; it is a calculated investment.
Plants pump carbon-rich exudates into the rhizosphere to feed the soil microbiology—the biological Workforce. In the underground marketplace, plants exchange carbon sugars for essential minerals, water, and immune-boosting compounds delivered by micro-organisms.
Peer-reviewed research published through the Frontiers in Plant Science journal research topic, Exchanges at the Root-Soil Interface: Resource Trading in the Rhizosphere that Drives Ecosystem Functioning, confirms that carbon serves as the universal currency driving biological commerce. Without a constant influx of plant-derived carbon, the subterranean Workforce starves, economic trade ceases, and the system collapses.
Building the Soil Sponge: Glomalin and Biological Concrete
The structural magic of carbon manifests through transformation into soil organic matter, the standard industry term for the lifecycle phases within the earth. In soil science, institutional standards maintain that soil organic matter consists of three distinct, interconnected phases.
As documented by the USDA-NIFA Sustainable Agriculture Research and Education (SARE) Program, the soil organic matter architecture breaks down into simplified categories:
- The Living: This phase consists entirely of living biology, including bacteria, fungi, protozoa, nematodes, micro-arthropods, and plant roots. The soil microbial communities reside squarely within this category.
- The Dead: This phase consists of active, easily decomposable organic materials, such as recently dead microbes, fresh root exudates, and decaying plant litter. This material serves as the primary food source for the living Workforce.
- The Very Dead: This phase consists of stable humus and highly complex carbon molecules, including glomalin bound to mineral surfaces, which can remain locked in the soil matrix for decades or centuries.

As the biological Workforce processes carbon sugars through these three phases, it builds the physical framework of the soil. Specifically, arbuscular mycorrhizal fungi weave through the soil matrix and exude a durable, carbon-centric glycoprotein called glomalin. Discovered in 1996 by Dr. Sara Wright at the United States Department of Agriculture (USDA) Agricultural Research Service, glomalin acts as the biological concrete of the subterranean world.
Glomalin binds individual particles of sand, silt, and clay together into stable micro-aggregates. Small aggregates then bind into larger macro-aggregates, creating a complex, porous structural framework known as the Soil Sponge.
Without carbon-based glomalin to glue soil particles together, individual grains of earth compact under pressure or wash away in the rain. Carbon creates the architectural spaces—the microscopic caves, tunnels, and porous voids—that allow soil to breathe and replenish water reserves. The structural porosity allows oxygen to circulate, roots to penetrate deeply, and micro-organisms to build thriving communities.
The Subterranean Plumbing Network
Beyond structural stability, the carbon-built Soil Sponge serves as the primary water management infrastructure of the planet. Voids created by carbon aggregates function as a vast, interconnected plumbing network.
When rain falls on a carbon-rich Soil Sponge, the porous architecture effortlessly absorbs and infiltrates moisture, pulling it deep into the subterranean profile. The absorption mechanism creates a reliable Water Vault.
Data published by the Natural Resources Defense Council (NRDC) in the NRDC Composting and Soil Health Brief substantiates that for every one percent increase in soil organic matter, the soil can retain roughly twenty thousand gallons of water per acre. Retained moisture hydrates the biological Workforce during dry spells, sustains plant life through droughts, and slowly filters downward to recharge localized aquifers. Carbon infrastructure effectively mitigates the dual planetary crises of flooding and desertification by transforming destructive deluges into life-sustaining subterranean reserves.
Restoring the Architectural Foundation
For centuries, conventional management practices have systematically depleted the subterranean carbon reserve. Continuous tilling, toxic-chemical saturation, and prolonged fallow periods disrupt the carbon cycle, starving the biological Workforce and shattering glomalin-bound aggregates. When carbon is lost, the architectural infrastructure crumbles, collapsing the Soil Sponge into a compacted, lifeless layer of dirt incapable of absorbing water or cycling nutrients.

True ecological health relies on maintaining a balanced distribution of carbon across all five planetary pools. When the carbon cycle returns to equilibrium, the element functions effectively as the foundational brick and mortar of the subterranean metropolis. Restoring the architectural integrity of the Underground Community allows the planet to reclaim its natural capacity to manage water, grow nutrient-dense food, and foster enduring community resilience.
