The Data Center Showdown in Lackawanna County

by Dave Rollo

As the artificial intelligence (AI) boom explodes with a race for ever more powerful models, so does the need for its infrastructure. This takes the form of huge, windowless buildings housing thousands of data servers. Projects may involve numerous buildings—sometimes a dozen or more—with added infrastructure such as hundreds of backup generators. These amalgamations are termed data centers or, in some cases as an indication of their enormity,


Spring: Ever More Silent

by Alix Underwood and Marwa Ebrahem

Humans have come to rely on chemicals not only to increase the fruits of our agricultural labor but also to stop other species from partaking in the feast. And the toll exacted by these “pest”-killing chemicals is immense.

Over 60 years ago, in Silent Spring, Rachel Carson detailed the effects of DDT, the first widely used chemical pesticide, on ecosystems and human health.


The Vicious Fertilizer Cycle and the Growth Economy

by Alix Underwood and Marwa Ebrahem

The size of our economy, measured by gross domestic product (GDP), is intimately linked to our use of artificial fertilizer. So is the ecological havoc we are wreaking on the planet and its inhabitants.

Between 2002 and 2018, while the population increased by 22 percent, the per-hectare use of synthetic nitrogen, phosphorus, and potassium fertilizers—the three most common types—increased by about 23,


On Public Lands, a Feeding Frenzy for Growth

by Kirsten Stade

American public lands management has always embodied a tense balancing act between conservation and exploitation. Too often the balance has tipped in an unsustainable direction. But the Trump Administration appears determined to break the scale, with unprecedented efforts to sell out public lands to extractive industries.

Four agencies manage most federal lands. The Bureau of Land Management (BLM), the U.S. Fish and Wildlife Service (USFWS), and the National Park Service (NPS) within the Department of the Interior,


Elk County: A Story of Restoration and Recapitulation

Pennsylvania is known for its public lands and forests. Beautiful Elk County, Pennsylvania, is no exception. It boasts rugged, forested scenery with rolling hills, deep valleys, numerous streams, and vast woodlands. Part of the Pennsylvania Wilds,


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.


Technocene Ground Zero: Counties Face Off with Data Centers

by Amelia Jaycen

In counties across the U.S.—rural and urban, democrat and republican—communities are living up close and personal with data centers. And the new neighbor is a real nightmare.

The number of data centers in the U.S., whether planned, under construction, or operating, is 3,897. This is by far the most anywhere in the world, and the number is increasing weekly.

We are hitting our heads on the ceiling of limits to growth.


Challenging Land Use and Abuse in Allamakee County

by Dave Rollo

Allamakee County lies in the northeast corner of Iowa, bordering Minnesota and Wisconsin. It is part of a three-state region that, unlike most of the upper United States and Canada, escaped glaciation during past ice ages. This geological oddity is immediately obvious to visitors by the dramatic terrain of bluffs, hills, and valleys. Expansive plains characterize most of the rest of Iowa, where miles-thick glaciers moved over the land like a bulldozer,
