Not long before I was appointed by The University of Michigan-Dearborn as a scientist in 1963, I had believed that most people in positions of leadership, once they were well-informed scientifically, would work to make appropriate decisions for living rightly on Earth. If the science of life and the biosphere were understood, good decisions would be made. But I was wrong. That belief was shaken as I came to discover people making bad decisions even when they had access to science and had the capacity to understand it—even more so when decisions were made contrary to maintaining the integrity of their communities and the integrity of the biosphere.
My first dramatic realization of such cultured disregard and cultured ignor-ance of the science of deserts came while my wife Ruth and I lived on the open desert in southern California during the summer of 1961. I was researching how animals lived in this dry, hot, and thirsty land, on a study site situated on a nearly barren alluvial fan at the mouth of Deep Canyon—a gorge whose dry river bed originated in the San Jacinto Mountains to the south. Nearly every day during those three months of summer I walked my study site, signaling to Ruth under a nearby canopy the location of individually-marked Desert Iguanas canopy at the edge of this site, as she and I entered notes on their location and behavior. Three times every hour I would walk another 15-minute round, rest for 5, continuing this during the course of the day and drinking about a liter of water an hour.1
One day I drove a few miles west of my research site to an area of blowing sand where desert dunes were being leveled by men in bulldozers. The dunes were being flattened, sprinkled from water trucks, and covered with poured concrete slabs upon which houses were being built. One end of a just-completed ranch-style house had been undercut by desert winds, had cracked in the middle, and now hung into a wind-scoured hole. Incoming residents seemingly overlooked this event, even as they complained to me that Riverside County plows came too infrequently to push drifting sand off their paved streets. Rainfall that year was two and 54/100 inches; the regional water table was dropping 1 foot per year. Surface temperatures exceeded 150 degees F nearly every day during July and August on my research site.
Life magazine pictured these newly-built homes in the Palm Desert dunes on the cover of their March 23, 1962 issue, announcing, “A New Vista in the American West: OPENING UP THE DESERT FOR LIVING.” Reading the article again in 2016, I found it saying of its new human residents, “Their continuing enthusiasm is a distinct triumph for advanced air conditioning and the positive thinking of real estate developers, whose missionary bullishness, more than any other single factor, has been changing the face of the desert.” And then, “In a moment of uncommon candor, one of these salesmen recently looked out over a bleak track and mused: ‘There’s no real reason for anyone to be here — and they wouldn’t be if we weren’t bringing them in, selling them, convincing them it has a great future.’ ”2
More recently, similar disregard and cultured ignor-ance of science is being illustrated by events in the coastal Bald Cypress – Tupelo swamps of Louisiana. The science of wetland systems describes well their vital role in the coastal landscape, demonstrating clearly how their component cypress trees with widely buttressed trunks, intermeshing matrix of tough root systems with their protruding cypress knees, and flexible branches and crowns absorb furious energy of hurricane winds, and hold the landscape in place to the benefit of other creatures, inland landscapes, and human settlements. Yet, cypress trees are being cut and ground up as mulch to beautify gardens and landscapes in Florida and to the northern states. Their wonderfully marvelous services to Louisiana life and landscapes are eschewed by their destroyers, and ongoing destruction continues while protective coastal wetlands convert to marshland which is washed to the sea. Highly integrative wetland science is robustly published by scores of scientists at Louisiana University, scientists at Southeastern Louisiana University, and across the U.S., and yet cypress trees and their remarkable ecosystem services are sacrificed to powerful wood-chippers at great profit and tremendous loss.34
Science asks the question, “How does the world work?” Seeking the answer to this question is not only important but critical for wise habitation and use of the land. But as these two examples show, it is not enough to know. While it is vitally necessary, science is not at all sufficient. Science must be accompanied by ethics. Ethics asks the question “What is right?” Seeking the answer to this second question, interactively with the first, is critical to becoming earth wise.5
Thoughtful people—and that should mean everyone—soon find both science and ethics vitally necessary. Yet these are insufficient without corresponding praxis. Praxis asks the question, “What then must we do?” Understood as including study and development of practice, praxis must result in doing what must be done—now, and into the future with resolve and diligence.6 And such practice ranges from practical action to wisely deciding to “let it be.”7 This relationship can be pictured as a triangle we can call the science-ethics-praxis triad:8
Science: How does the world work?
Ethics: What is right? Praxis: What then must we do?
In my own Wisconsin community, the Town of Dunn, we answered the first two questions by discovering everything we needed to know scientifically and ethically about the 34.5 square miles of land we held in trust, and summarized this in what we called The Town of Dunn Open Space Preservation Handbook.9 But this Handbook—and developing a plan based upon it, was not sufficient. We next had to make sure that it all was put into practice. We achieved this by translating what we had learned into our land stewardship plan, and then codified this plan into laws and ordinances. Then—and this is the highly crucial part—they were applied with diligence, and most importantly were enforced with no exceptions. Knowing, however, that sometimes we might not “get things right,” we also provided for adjusting our plan and ordinances annually with full citizen discussion; this allowed us to address inadvertent mistakes and injustices without having to make exceptions to our plan and ordinances. In all of this we have come—citizens all—to be stewards of our own place.
Earth stewardship—stewardship of our lives and landscapes—was the outcome of our work in integrating science, ethics, and practice into fruitful interaction.10 We published our work on paper, but most importantly our major publication is in our lives and landscapes. This practical publication is our principal measure and testimony of how well we are keeping the three corners of the science-ethics-praxis triad interacting together to serve and to keep what we hold in trust.
