Inspiration for Dr. Seuss's 'The Lorax' may be from real plant and animal life in Kenya

July 23, 2018

Ever since "The Lorax" by Dr. Seuss (the pen name for Theodor Geisel), was first published in August of 1971, it has captured the minds of young readers. It's been translated into 15 languages and more than 1.6 million copies were sold by 2010. The short and spunky, furry orange creature called the Lorax, who "speaks for the trees," is famous for his environmental pleas, as he demands that the Once-ler stop cutting down the Truffula trees to make yarn for the Thneeds.

In the book, as the landscape becomes dotted with Truffula tree stumps, the Lorax explains:

"NOW...thanks to your hacking my trees to the ground,
there's not enough Truffula Fruit to go 'round..."

But what exactly did the Lorax mean by "my"? Did he consider himself the owner of the forest, as some critics have claimed? A Dartmouth-led study proposes a new theory that the Lorax viewed himself as a part of the Truffula forest and was speaking as the personification of nature rather than as some sort of ecopoliceman. The essay is published in Nature Ecology & Evolution.

The findings propose that the Lorax had a symbiotic relationship with other species, debunking notions that he was trying to exert his authority over the forest. The research also finds that Geisel's inspiration for elements in the Lorax may have been based on an actual, tree and monkey species in Kenya.

"Our analysis illustrates how the Lorax is not some self-proclaimed steward of the environment but rather a participating member of the ecosystem. In fact, many of the themes embedded in the narrative are textbook examples of ecological interactions. In my opinion, many of these dynamics were based on Geisel's own observations while he was in Kenya, and it's no accident that the Lorax looks the way he does," explains lead author Nathaniel J. Dominy, the Charles Hansen Professor of Anthropology at Dartmouth, whose expertise includes nonhuman primate foraging ecology.

Historical records indicate that Geisel wrote 90 percent of "The Lorax" while visiting Mount Kenya Safari Club in September 1970. That was the year that the U.S. environmental movement was born with the creation of the National Environmental Protection Act, Earth Day and the Environmental Protection Agency.

The illustrations of "The Lorax" provide important clues. For example, the spiky, barren trees outside the Once-ler's home look like the whistling thorn acacia (Acacia drepanolobium), a common tree found on the Laikipia plateau in Kenya. If Geisel noticed these trees while he was there, then he probably also saw patas monkeys (Erythrocebus patas), which rely on the acacia tree for more than three-fourths of their diet. The acacia tree and the patas monkey have a commensal relationship in which neither species is harmed. It is this very notion of commensalism that grounds the story of "The Lorax," according to the research team.

"The proposal that the patas monkey might be the real-life referent for Dr. Seuss's Lorax introduces an interpretation of the children's tale that undermines the core assumption of human exceptionalism. If we really want this biodiverse planet to thrive, we cannot consider ourselves as separate from the environment. This is the deep message of the Lorax: He is a part of the ecological system not apart from it," explains co-author Donald E. Pease, a professor of English and the Ted and Helen Geisel Third Century Professor in the Humanities at Dartmouth. Pease is an expert on Theodor Geisel and author of "Theodor Seuss Geisel" (Oxford University Press, 2010).

"If the Lorax is genuinely part of the environment, he is modeling the attitude we need to assume," adds Pease.

The study also finds that the Lorax has physical features similar to the patas monkey, as it has orange hair and stands on two legs. The findings demonstrate that the Lorax's face looks more like one of the species of Kenyan monkeys than the most similar-looking Seussian character, after a computer-generated analysis was used to compare their faces.

The research team adds that we may be "witnessing a prophetic example of life imitating art imitating life," as acacia tree populations in Kenya have been shrinking due to climate change, as have patas monkeys in recent decades.

Toward the end of "The Lorax," Dr. Seuss makes a call to action through the Once-ler, who explains:

"UNLESS someone like you cares a whole awful lot,
Noting is going to get better.
It's not."

#521 The Curious Life of Krill
Krill may be one of the most abundant forms of life on our planet... but it turns out we don't know that much about them. For a create that underpins a massive ocean ecosystem and lives in our oceans in massive numbers, they're surprisingly difficult to study. We sit down and shine some light on these underappreciated crustaceans with Stephen Nicol, Adjunct Professor at the University of Tasmania, Scientific Advisor to the Association of Responsible Krill Harvesting Companies, and author of the book "The Curious Life of Krill: A Conservation Story from the Bottom of the World".
