The Economic Priority of the Seven Wealthiest Countries: More Wealth

by Alix Underwood

Almost half of humanity lives below $6.85 per day. This population does not consume goods and services at a rate exceeding Earth’s capacity. Yet here we sit, on the wrong side of six of the nine planetary boundaries identified by the Stockholm Resilience Centre.

How did we get here? Via the economic activity of the other half of humanity. The planet, and all its inhabitants,


Whose Behavior Needs to Change? The Other Side of the International Development Coin

by Alix Underwood

“Give a man a fish and you feed him for a day. Teach him how to fish and you feed him for a lifetime.” The Western-led international development sector, born in the aftermath of World War II, has evolved according to this (ironically) Chinese proverb. To better reflect the status of international development, I would append the following sentences to the worn-out proverb: “Use advanced extractive technology to harvest all the fish from the man’s ocean,


Service Providers in the Trophic Theory of Money

by Brian Czech

Steady State Herald readers are familiar with the theory that money originates from an agricultural surplus that frees hands for the division of labor—and thenceforth the exchanging of money. This trophic theory of money (TTOM) helps us understand not only the historical origins of money, such as in Mesopotamia (the “Cradle of Cash”), but also the annual origins of “warranted money” in the grain belts of the world.


The Olympic Spirit: Friendly Competition or Unsustainable Growth?

by Mark Cramer

Every four years, the Summer Olympics present a rare opportunity for friendly competition and collaboration among nations. The public has an opportunity to witness a myriad of sports that otherwise never make the headlines. Talented athletes get a rare chance to display their skills before an international audience.

The Olympics offer a venue for peaceful, international solidarity. Yet they also present a seemingly insurmountable ecological challenge. To begin with,


A Trophic Perspective on Fossil Fuels

by Alix Underwood

Like the economy of nature, the human economy has a “trophic” structure. In nature, nutrition and energy flow from plants to herbivores to carnivores, with each of these comprising a trophic level of the ecosystem. In the human economy, materials and energy flow from agriculture and other extractive activities to heavy manufacturing to light manufacturing. Both economies include service providers, such as pollinators in nature and the transportation sector in the human economy.


Introducing the Luxury Cap Act

by Daniel Wortel-London

Even as nearly a billion people go hungry every day, the wealthiest one percent of the world’s population is purchasing ever-more expensive toys. Yacht sales grew by an average of 22 percent per year between 2014 and 2022. Private jet sales have boomed since the start of the COVID pandemic. The global luxury jewelry market, already huge at $56.5 billion,


How to Avoid the Scarcity Scare

by Gary Gardner

In congressional testimony last November, Isabel Munilla, an official from the Department of Energy, gave an alarming assessment of U.S. reliance on foreign minerals. For 31 of 50 critical minerals, she warned,”…the U.S. relies on other countries for more than 50 percent of our requirements…Our reliance on non-allied foreign sources for these materials is neither sustainable nor secure.” Munilla employed what we might call the “scarcity scare”—the panic that supplies of critical minerals may be insufficient for all nations to participate in the transition to clean,


It’s Time to Ban Earth-Damaging Ads

by Daniel Wortel-London

Advertising works. A recent study by the Advertising Association finds that every dollar of ad spending drives up sales by $21. Ads get us to recognize brands and hum jingles even if we are annoyed by pop-ups. They are particularly effective in driving the kind of unsustainable consumption that is destroying our planet.

This begs a question: Should advertising be limited for the sake of the environment?


Time to Make a Material Difference

by Gary Gardner

Well, COP 28 ended yesterday with (seeming) agreement to (sort of) walk down the fossil fuel ladder toward a (not for a while) sustainable future. Geez! It’s almost 2024, more than half a century since Limits to Growth was published, and the human family is in a pouting mood. Why is it like pulling teeth to do the right thing, sustainability-wise? Why are we sleepwalking toward a cliff?

The public is rattled by inflation, credit card debt is through the roof, and gift-giving is a real strain for many.
