Aldo Leopold was an author, philosopher, naturalist, scientist, ecologist, forester, conservationist, and environmentalist who made the case that land was about more than just economic exploitation. He introduced the concept of a “land ethic.”
Aldo Leopold introduced the concept of a “land ethic.” He fundamentally challenged us to rethink our relationship with the land. Land, according to Leopold, is about more than just economic exploitation.
He taught us that we need to listen to nature and what it’s telling us. His Sand County Almanac became one of the most important and influential works of the environmental movement.
Leopold’s land ethic grew out of his lifetime of experiences and values. As an author, philosopher, naturalist, scientist, ecologist, forester, conservationist, and environmentalist, Leopold was a leader of the Conservation Movement in America.
Aldo Leopold helped give birth to the Modern Environmental Movement.
He is one of More Than Just Parks Environmental Heroes.
The Frontier In American History | Aldo Leopold’s Land Ethic
When Aldo Leopold was growing up Frederick Jackson Turner formulated a theory to explain the relationship between Americans and the land. He called his idea “The Significance of the Frontier in American History.”
Turner wrote, “The existence of an area of free land, its continuous recession, and the advance of American settlement westward, explain American development.”
Aldo Leopold acquired his love of the land from his father, Carl. He taught all of his children to appreciate the natural world. By the time he was thirteen years of age, Aldo, who was the oldest of the Leopold children, was accompanying his father on hunting trips.
The Yale Forest School | Aldo Leopold’s Land Ethic
Gifford Pinchot was the first director of the U.S. Forest Service. Prior to the creation of the Forestry Service in 1905, Pinchot helped to create America’s first school of forestry at Yale University in 1900.
Pinchot was the first American to receive professional forestry training in Europe. The School was founded with a gift from the Pinchot family to ensure a continuing supply of professionals to carry out the work of forest managment.
Five years after the school’s creation, Aldo Leopold enrolled in the Sheffield Scientific School, which offered Yale undergraduates a preparatory training program before moving on to his studies at the forestry school.
Leopold completed his work as a graduate student in 1908-09. From there, his career began as a forester. Leopold would begin the next phase of his education.
The Education Of A Forester | Aldo Leopold’s Land Ethic
Apache National Forest
Leopold’s first assignment was the Apache National Forest. He would be out for several months at a time to inventory the land and estimate the available timber reserves.
Leopold had been taught the utilitarian approach to conservation whereby people have a right to use natural resources, but also an obligation to use them wisely and efficiently.
His boss, Gifford Pinchot, referred to this approach at “the greatest good for the greatest number over the long run.”
Carson National Forest
Leopold’s second assignment took him to the Carson National Forest. Here he saw firsthand the impact of soil erosion on the land. Sheep, whom John Muir once referred to as “hoofed locusts,” had been allowed to graze.
This grazing decimated the grasslands. Leopold began to see the limitations of the utilitarian approach.
He then became supervisor of the Carson National Forest. While on an extended trip in 1912, he found himself sleeping in a soaked bedroll after a hailstorm hit. Leopold returned with his face, hands, arms, and legs swollen.
He had contracted Bright’s Disease. Leopold’s kidneys had failed, toxins had built up in his system and he took a six week sick leave unaware of the fact that he would not return to the Forest Service for almost two years. He was, however, lucky to have survived.
From Forestry To The Protection Of Wildlife | Aldo Leopold’s Land Ethic
After sixteen months, Aldo Leopold finally returned to the Forest Service. When he did, he was thinking about more than just the management of timber and other forest resources.
As a child, he had been drawn to wildlife through his hunting expeditions with his father. Increasingly, Leopold became concerned about the future of wildlife and whether, in fact, there would be any species left to hunt.
Aldo Leopold left the Forest Service in 1918 to take a job with the Albuquerque Chamber of Commerce. He rejoined the Forest Service a year later as an Assistant District Forester in Charge of Operations.
He was now on the frontline of changes threatening the long-term viability of the American Southwest. This job, like all of the previous ones, formed a part of his education.
Increasingly, Leopold came to embrace wilderness preservation as a crucial component of any viable long-term land management plan.
Leopold Outgrows The Forest Service | Aldo Leopold’s Land Ethic
Aldo Leopold’s final job with the U.S. Forest Service was as assistant director at the Forest Products Laboratory in Madison, Wisconsin.
He had established himself as a pioneer in national forest policy and was becoming one of the leading voices in the conservation movement.
For Leopold, however, the Forest Service was no longer the appropriate venue for his growing list of interests and causes.
He moved on to work as a wildlife specialist for the Sporting Arms and Ammunition Manufacturers Institute before becoming, like Gifford Pinchot before him, a consulting forester.
Aldo Leopold’s final career move took him into the classroom. He became a professor of game management at the University of Wisconsin.
From this position, he went on to become a founding member of the Wilderness Society and was active in numerous professional organizations.
The Land Ethic
More importantly, Leopold began to train the next generation of conservationists while continuing his research into what would became known as the “land ethic.”
Leopold was a popular professor who had hundreds of undergraduate students interested in taking his courses. He also worked closely with a number of graduate students who made contributions of their own to the growing cause of conservation and environmentalism.
A Sand County Almanac | Aldo Leopold’s Land Ethic
At the end of his career, Leopold assembled a collection of essays. His plan was to publish these essays with a unifying theme which embraced his land ethic. Leopold was in the process of completing his most important work when tragedy struck.
While fighting a fire near his vacation home, he suffered a massive heart attack and died.
A Critical Success
His son, Luna Leopold, who had become a conservationist, saw to it that his father’s final work was published. A Sand County Almanac was a huge critical success. At a time when others were predicting ecological catastrophe, Leopold’s book offered a ray of hope.
Published in 1949, the book encouraged a new generation of conservationists in the 1950s. In his book, Leopold defined conservation as “a state of harmony between men and land.”
This definition demonstrated his desire for a healthy relationship between the needs of man and the needs of the environment.
To Treat The Land With Respect
What Leopold did was urge humankind to treat the land with respect and not to base the value of everything simply on monetary gain. Leopold said that humans could no longer behave as the masters of everything by determining what should and what should not exist.
The message of his final work is that a healthy environment requires all of its parts working together.
The “Big Three” Of The Environmental Movement | George Perkins Marsh
Through their writings, three American authors have arguably had the greatest impact on the environmental movement. One was George Perkins Marsh.
Through his Man & Nature, published in 1864, Marsh was among the very first to include human impacts in our understanding of the natural world.
More than that, however, was his challenge to this notion, which dominated 19th century thinking; namely, that humankind’s efforts to shape its environment was always beneficial.
The fundamental message of Man and Nature is that nature does not heal itself from our destruction.
The “Big Three” Of The Environmental Movement | Rachel Carson
A second was Rachel Carson. Prior to Silent Spring, it was believed that humankind was the master of its own destiny. We could bend the physical universe to meet our needs.
Rachel Carson showed us that there were limits to how far the universe will bend in our favor. All life is interconnected. Actions have consequences. If we make life unfit for one species then we make it unfit for others as well, including ourselves.
The Legacy Of Aldo Leopold | Aldo Leopold’s Land Ethic
Aldo Leopold was the final member of this important trio of authors whose works provide a foundation on which the modern environmental movement has built.
At a time when technological advances, such as chemical pesticides and nuclear weapons, placed our planet in increasing peril, Aldo Leopold brought a greater understanding of our relationship with the natural world.
Like George Perkins Marsh and Rachel Carson, he challenged the notion that all human impacts are beneficial.
Rethinking Our Relationship With The Land
Leopold challenges us to rethink our relationship with the land. Leopold’s early recognition of keeping and restoring biological diversity and ecological processes became central to his evolution of thought on the environment.
Leopold taught us that we need to listen to nature and what it is telling us. Our use of natural resources needs to become more intelligent. Leopold challenges all of us to seek alternatives which restore an essential balance and harmony within the natural world.
We owe it to ourselves and to generations yet to come to heed his wise words and follow his sterling example.
