A Dry Reckoning for Finney County

by Dave Rollo

Finney County lies in the southwest quadrant of Kansas and above the massive Ogallala Aquifer. Running mid-continent from the Dakotas to Texas, the Ogallala is the largest aquifer in North America. Once holding the volume equivalent of Lake Huron, the aquifer was first tapped for high-volume irrigation in 1909. This fundamentally transformed the landscape from ecologically diverse tallgrass prairie to energy- and water-intensive monoculture crops on an immense scale.


Hitting Freshwater Rock Bottom

by Alix Underwood and Marwa Ebrahem

Freshwater is arguably the single most essential resource for human life. Yet, its use seems more abstract than that of solid materials. Freshwater sources exist everywhere that humans do, but they are often hidden from view, buried underground or frozen in glaciers. It’s hard to fathom the scope and the impact of the 3.95 trillion cubic meters of freshwater the human economy extracted in 2021.


Growth of an Economy, Death of a River

by Amelia Jaycen

The Colorado River has a simple math problem: More water is taken out than nature refills every year. The gap between the two is also widening. Every year, an increasing amount of water is taken out of the Colorado River, as demand for water increases across the arid American West. Meanwhile, every year less water is available in the river and its tributaries as climate change and other manmade stressors cause imbalances in natural systems.


Greenwashing in the Amazon: Debunking False Green Solutions

by Mauricio López

The concept of greenwashing has gained unfortunate relevance, especially regarding the energy transition. Greenwashing occurs when companies, governments, or institutions promote products, services, or projects as ecologically responsible, while minimizing or hiding their negative impacts. The inhabitants of the Amazon, particularly Indigenous peoples, are witnessing how greenwashing is not only problematic from an environmental perspective. It is also detrimental to human rights and social justice.

Circularity in the Gold Sector

by Ramachandran Kallankara and Vivek Vivek

Twenty years ago, visionary economist Herman Daly exhorted the readers of Scientific American to create new ways of thinking towards a sustainable economy:

“The global economy is now so large that society can no longer safely pretend it operates within a limitless ecosystem. Developing an economy that can be sustained within the finite biosphere requires new ways of thinking.”

Economies are triangular,


Influenced to Overconsume: How Social Media Hijacks Sustainability

by Priya Thompson

We live in an age defined by contradiction. On one hand, the climate crisis demands urgent and systemic action. On the other hand, we are more connected to a digital world that profits—at great ecological cost—from our distraction, desires, and deeply human need to belong.

This tension is constant and personal for many Gen Z users, who overwhelmingly identify with sustainability as a lifestyle and a moral imperative.


Corporate Conservation Funding: A Contradictory Conundrum

by Kali Young

Apple, Cargill, Walmart, United Airlines, Chevron, BlackRock, Starbucks, Ford Motor Company, Amazon, McDonald’s, Sotheby’s…What do they all have in common? They are among many megacorporations that fund Conservation International, one of the most prominent conservation foundations in the world. World Wildlife Fund and the Conservation Fund, also conservation powerhouses, have similar though less expansive funder profiles.

Walmart and BlackRock are two of the world’s top deforestation perpetrators.


Introducing the Sustainable Transportation Act

by David Shreve

While transportation is vital to American prosperity, the transportation sector is the largest direct contributor of U.S. greenhouse gas emissions among all economic sectors. Even though passenger-car efficiency has steadily increased in recent years, the sector’s contribution to environmental degradation has continued to rise. Since 1995, U.S. transportation sector emissions have risen by almost 20 percent.

We cannot ignore the principal problems in the U.S.


Hacking the Business Growth Imperative

by Kali Young

“Despite its immensity, the Earth’s resources are not infinite, and it’s clear we’ve exceeded its limits. But it’s also resilient. We can save our planet if we commit to it.” – Yvon Chouinard, founder of Patagonia

In 2022, Patagonia founder Yvon Chouinard took a bold step to make the Earth, in essence, the company’s only shareholder. Chouinard explained that he doesn’t respect the stock market and believes that companies become irresponsible after going public.


Introducing the Sustainable Housing Act: Shelter for All in a Steady State

by David Shreve

Housing in the United States (and in many other nations) is plagued by many problems and shortcomings. Among the most critical are increasingly unaffordable prices and bewildering geographic cost variations. Connected to these are additional problems associated with forced sprawl, the needless destruction of vital ecosystems, and labor market rigidity.

The residential cost problem is paramount and can no longer be dismissed as a predicament limited to isolated markets.
