Sonic Earth: Life, Loss and Listening

We start Season 4 of The Subverse, which will focus on “Earth”, with a conversation with David George Haskell, a writer and biologist. We focus on his latest book, Sounds Wild and Broken, which explores the story of sound on Earth. It was a finalist for the 2023 Pulitzer Prize in Nonfiction and the PEN E. O Wilson Literary Science Writing Award. In it, David writes about how, three and a half billion years ago, sunlight found a new path to sound: life.

The wonders of Earth’s living voices emerged after hundreds of millions of years of evolution that unfolded in communicative silence. From the ancient cricket Permostridulus which bears the earliest known sound-making structure, a ridge on its wing, this sonic creativity was spurred on by some amazing marvels, anatomical and otherwise. They range from insect wings and flowering plants to ciliary hair and even human milk.

Now, both land and water are far from silent; fish drum and twang, whales sing, birds chirp and wings buzz. The sonic diversity of the world is rooted in the divergent physical worlds and social lives of animals and the happenstances of history. Every species has a logic, a grammar, to its sound making. And still, the process of hearing is one of unity at the cellular level. Sound also travels across oceans, creating a sort of global unity in sonic communication. 

Sound is ephemeral, instantly dissipating, and yet can be older than stone. So, in listening to animal voices around us, we are taken back into deep time and legacies of sonic geology. But it is also a ledger of loss. Our species is both an apogee of sonic creativity and the great destroyer of the world’s acoustic riches. As we get noisier, we diminish sonic soundscapes, bequeathing the future an impoverished sensory world.

This sensory crisis is an important measure of the environmental crisis, and a powerful untapped tool for environmental justice. How do we create a poetics and politics of listening? We tend to think of experiences of beauty and of creativity as somehow separate from politics and ethics, but Haskell points out that they are deeply intertwined. We are embodied sensory beings. As a species, we need to gather and celebrate the voices of non-human beings.

Technological advances have allowed us to record these soundscapes to check on the health of ecosystems. But when we get too reliant on technology, we ignore the wisdom of the people who have lived in the forest for centuries and don’t need gadgets to gauge the health of the forest, or to protect it. David spoke of the generative capacity of sound which comes from life and interconnection. He closed with an invitation to take a few minutes of each day and listen, without judgement or expectation, and let sound do its work.
