“Every human being is a colony,” Pablo Picasso once said. The insight is made literal in Ed Yong’s acclaimed book, I Contain Multitudes, about our hidden relationship with the microbial world. “If we zoomed in on our skin,” he writes, “we would see them: spherical beads, sausage-like rods, and comma-shaped beans, each just a few millionths of a meter across. They are so small that, despite their numbers, they collectively weigh just a few pounds in total. A dozen or more would line up cosily in the width of a human hair. A million could dance on the head of a pin.”
These microbes are not just hitching a ride, but enabling us to become ourselves: they help digest our food, sculpt our organs, and craft and calibrate our immune systems. To be at all, Yong demonstrates, is to be in partnership with them. Yong’s work has contributed to a radical shift in how we understand animals — from discrete organisms motivated by competition to living islands, communities of hidden beings.
Over 40 percent of the Earth’s surface is open ocean that is over 200 miles from the nearest shore. These international waters exist outside national jurisdiction and almost entirely free of rule of law. World-renowned investigative journalist Ian Urbina spent five years reporting about what life is like for the humans who roam these seas and about the astonishing array of extra-legal activity that goes on there. Urbina travelled to every continent and every ocean — often hundreds of miles offshore — to report stories from this vast legal void. These narratives are compiled in his best-selling book, The Outlaw Ocean: Journeys Across the Last Untamed Frontier.
In his years of non-stop voyages, Urbina risked his life to bear witness to the inhumanity faced by humans in these waters. He witnessed shackled slaves on fishing boats, joined high-speed chases by vigilante conservationists, rode out violent storms, and observed near mutinies. He lived on a Thai vessel where Cambodian boys worked 20-hour days processing fish on a slippery deck, shadowed a Tanzanian stowaway who was cast overboard and left to die by an angry crew, and met men who had been drugged, kidnapped and forced to cast nets for catch that would become pet food and livestock feed. These stories and many others together make The Outlaw Ocean, a masterpiece of investigative journalism and a riveting portrait of a sprawling and often dystopian world where humans, animals and the environment are regularly treated with depravity.
“One of the many obstacles to reckoning with global warming is the stubborn notion that humans are not powerful enough to affect the entire planet,” writes our guest, journalist Ferris Jabr, in a recent New York Times Opinion piece. “In truth,” he continues, “we are far from the only creatures with such power, nor are we the first species to devastate the global ecosystem. The history of life on Earth is the history of life remaking earth.”
Jabr argues that the time has come to revive an idea in biology known as the Gaia Hypothesis. Coined in the 1970s, the Gaia Hypothesis proposes that Earth is best understood not as a passive substrate or background to life but as a life form in its own right. It challenges us to rethink the definition of life—and with it, the process of evolution. To understand how sentient creatures have evolved on this planet, it suggests, is not only to grasp that animals are offshoots of an evolutionary tree; it’s to see the tree itself as one element of a dynamic, interrelated organism.
The early twentieth century bio-philosopher Jakob von Uexküll studied the private worlds of animals, and the perceptual differences and similarities between our worlds. Uexküll used a musical metaphor to explain his idea that each organism has a distinct, subjective and all-consuming life-world. To Uexküll, in the words of Dorion Sagan, “Organisms are instruments in a sort of celestial music show of which we hear only strains.” In his view, as Sagan writes, the multitude of earth’s organisms — a word derived from the Greek word, organon, for “instrument” — formed a many-membered orchestra of extraordinary richness.
Once, while attending a symphony by Gustav Mahler and sitting beside a young man absorbed in following along the score, Uexküll wondered if it is “the task of biology to write the score of nature.” “Each voice of a person or instrument is a being for itself, but one which melts into a higher form through point and counterpoint with other voices, which from then grows further, gaining richness and beauty in order to bring forward to us the composer’s soul,” he wrote. “Reading the score,” the young man sitting beside him told Uexküll, “one can follow the growth and branching off of the individual voices that, like the columns of a cathedral, bear the weight of the all-encompassing dome. Only in this way does one get a glance into the many-membered form of the performed artwork.” Our guest on this episode has devoted his career to observing and writing these interplaying “scores” of natures, the stories of animals, through prose and poetry. His work has allowed millions of readers to hear and appreciate anew strains of non-human animals in nature’s symphony.
