Denis Villeneuve

“Dune,” widely considered one of the best sci-fi novels of all time, continues to influence how writers, artists and inventors envision the future. Of course, there are Denis Villeneuve’s visually stunning films, “Dune: Part One” (2021) and “Dune: Part Two” (2024). But Frank Herbert’s masterpiece also helped Afrofuturist novelist Octavia Butler imagine a future of conflict amid environmental catastrophe; it inspired Elon Musk to build SpaceX and Tesla and push humanity toward the stars and a greener future; and it’s hard not to see parallels in George Lucas’ “Star Wars” franchise, especially their fascination with desert planets and giant worms. And yet when Herbert sat down in 1963 to start writing “Dune,” he wasn’t thinking about how to leave Earth behind. He was thinking about how to save it.

Herbert wanted to tell a story about the environmental crisis on our own planet, a world driven to the edge of ecological catastrophe. Technologies that had been inconceivable just 50 years prior had put the world at the edge of nuclear war and the environment on the brink of collapse; massive industries were sucking wealth from the ground and spewing toxic fumes into the sky. When the book was published, these themes were front and center for readers, too. After all, they were living in the wake of both the Cuban missile crisis and the publication of “Silent Spring,” conservationist Rachel Carson’s landmark study of pollution and its threat to the environment and human health. “Dune” soon became a beacon for the fledgling environmental movement and a rallying flag for the new science of ecology.

Though the term “ecology” had been coined almost a century earlier, the first textbook on ecology was not written until 1953, and the field was rarely mentioned in newspapers or magazines at the time. Few readers had heard of the emerging science, and even fewer knew what it suggested about the future of our planet. While studying “Dune” for a book I’m writing on the history of ecology, I was surprised to learn that Herbert didn’t learn about ecology as a student or as a journalist. Instead, he was inspired to explore ecology by the conservation practices of the tribes of the Pacific Northwest. He learned about them from two friends in particular. The first was Wilbur Ternyik, a descendant of Chief Coboway, the Clatsop leader who welcomed explorers Meriwether Lewis and William Clark when their expedition reached the West Coast in 1805. The second, Howard Hansen, was an art teacher and oral historian of the Quileute tribe.

Ternyik, who was also an expert field ecologist, took Herbert on a tour of Oregon’s dunes in 1958. There, he explained his work to build massive dunes of sand using beach grasses and other deep-rooted plants in order to prevent the sands from blowing into the nearby town of Florence — a terraforming technology described at length in “Dune.” As Ternyik explains he wrote for the US Department of Agriculture, his work in Oregon was part of an effort to heal landscapes scarred by European colonization, especially the large river jetties built by early settlers. These structures disturbed coastal currents and created vast expanses of sand, turning stretches of the lush Pacific Northwest landscape into desert. This scenario is echoed in “Dune,” where the novel’s setting, the planet Arrakis, was similarly laid to waste by its first colonizers.

Hansen, who became the godfather to Herbert’s son, had closely studied the equally drastic impact logging had on the homelands of the Quileute people in coastal Washington. He encouraged Herbert to examine ecology carefully, giving him a copy of Paul B. Sears’ “Where There is Life,” from which Herbert gathered one of his favorite quotes: “The highest function of science is to give us an understanding of consequences.” The Fremen of “Dune,” who live in the deserts of Arrakis and carefully manage its ecosystem and wildlife, embody these teachings. In the fight to save their world, they expertly blend ecological science and Indigenous practices. But the work that had the most profound impact on “Dune” was Leslie Reid’s 1962 ecological study “The Sociology of Nature.”

In it, Reid explained ecology and ecosystem science for a popular audience, illustrating the complex interdependence of all creatures within the environment. “The more deeply ecology is studied,” Reid writes, “the clearer does it become that mutual dependence is a governing principle, that animals are bound to one another by unbreakable ties of dependence.”

In the pages of Reid’s book, Herbert found a model for the ecosystem of Arrakis in a surprising place: the guano islands of Peru. As Reid explains, the accumulated bird droppings found on these islands was an ideal fertilizer. Home to mountains of manure described as a new “white gold” and one of the most valuable substances on Earth, the guano islands became in the late 1800s ground zero for a series of resource wars between Spain and several of its former colonies, including Peru, Bolivia, Chile and Ecuador.
