Gerardo Ceballos & Paul R. Ehrlich: 'Before They Vanish'—All The Life We Can Still Save from the Sixth Extinction | #25

Welcome to the Urgent Futures podcast, the show that finds signals in the noise. Each week, I sit down with leading thinkers whose research, concepts, and questions clarify the chaos, from culture to the cosmos.

My guests this week are Gerardo Ceballos & Paul R. Ehrlich

Gerardo Ceballos, one of the world’s leading ecologists, is a professor at the Institute of Ecology at National Autonomous University of Mexico (UNAM). He has established more than twenty protected areas in Mexico and is the author or coauthor of more than 55 books. Ehrlich and Ceballos are coauthors of The Annihilation of Nature: Human Extinction of Birds and Mammals.

Paul R. Ehrlich is the emeritus Bing Professor of Population Studies in the Department of Biology and the president of the Center for Conservation Biology at Stanford University. He is the author of The Population Bomb and Human Natures: Genes, Cultures, and the Human Prospect.

I don’t even know where to begin with this conversation. On the one hand, I’m still a little dumbfounded that I had the opportunity to have a conversation with two of the world’s leading conservation scientists, whose contributions not only to their respective fields but to the planet are historically significant.

On the other hand, this is one of the most devastating conversations I’ve had on the show, rivaled only by my chat with William Rees, which I’d say is thematically linked. The inciting incident for the conversation is the publication of their incredible new book, Before They Vanish, which they co-authored with Rodolfo Dirzo, who wasn’t able to also join the call because he’s out in the field. As you might gather from the title, the book is part-blaring siren, part-love letter. In in, the authors highlight how precious life on Earth really is, detailing not only the sheer variety of flora and fauna we are blessed to share the planet with, but how entangled they all are within ecosystems we humans have done so little to understand, and therefore have allowed ourselves to push to the brink of extinction.

Before I go any further, I want to say what I always say in episodes like this: go buy the book. These conversations are invitations to the subject matter, and I do hope they’re illuminating, but the book is where you’ll have the necessary time and mental space to fully grapple with the ideas.

Anyway, however bad you imagine the present extinction crisis is, which some have called the sixth mass extinction, this book basically argues it’s worse even than that. That stems from several factors, including the lack of historical data, the amount of information we still don’t have about various ecosystems, and the way we tend to measure extinctions—at the species level rather than at the level of discrete populations. The book also outlines the drivers of the extinction crisis and steps that we could take individually and collectively to mitigate the harms of modern industrial society, and advocate for protections that will begin to heal the planet.

Before people get up in my comments: I’m well aware of how individual responsibility has been weaponized by fossil fuel companies, and I too am wary putting the onus on individuals. That said, through their careers, these three authors have shown how much individuals can actually do. And we’re in the all hands-on-deck, everything-and-the-kitchen-sink moment to protect biodiversity. We should want to protect biodiversity because life is sacred, but even if that doesn’t land, as Ehrlich says in the interview, if we destroy biodiversity, we humans likely won’t survive either.
