Nate Hagens is a systems thinker and educator focused on the “human predicament” at the intersection of energy, economy, ecology, and human behavior. He’s been tracking how our financial stories and growth expectations have drifted away from the physical realities of energy, materials, and a finite biosphere. In this article he notes that the trends he has been warning about are no longer hypothetical; they are cohering into what he calls a “biophysical phase shift” in the global system.

He describes this as a drawn‑out transition, not a single crash, in which old assumptions about endless growth stop working as constraints push upward through our social and economic layers. To make this visible, he offers a “biophysical pyramid”: at the top, a financial layer of prices, wages, debt, and growth narratives; beneath it, a biophysical layer of energy, minerals, machines, and coordinated human activity; and at the base, the living earth that quietly supports everything without sending a bill. ​

For much of industrial history, the financial tip was small relative to the physical and ecological base, and it was easy to believe it could expand indefinitely. In recent decades, however, financial claims have swollen faster than the biophysical layer can support, while the waste of that expansion erodes the ecological foundation itself. As recognition of this mismatch spreads, Hagens expects more volatility, conflict over resources, and institutional strain, alongside a slowly growing awareness that biosphere risk is now a first‑order security and economic concern.

I suspect that it is exactly these kind of systems failures that will turn that slowly growing awareness into a hard reckoning with reality, as cascading breakdowns make our biophysical dependencies impossible to ignore in politics, markets, and everyday life.
