Eat, Poop, Die: Animals as the Arteries of the Biosphere
The Great Simplification #131 with Joe Roman
If plants are considered the lungs of the Earth, cycling CO2 into oxygen for animals to breathe, then animals act as the heart and arteries, spreading nutrients across the Earth to where it’s needed most.
This is the metaphor that today’s guest, conservation biologist Joe Roman, uses when describing his work studying how animals such as whales, otters, salmon, and midges provide vital ecosystem services, and how destruction of their populations – caused by modern industrial systems – affects the livability of the entire planet.
How has human activity drastically altered the balance and mass of species, and subsequently their ability to spread nutrients across the biosphere? What consequences must we face when biodiversity is diminished and nutrients are no longer dispersed as equally, leaving ecosystems with either extreme concentrations or scarcity of essential minerals, such as nitrogen and phosphorus? If we could “re-wild” diminishing species into their native habitats and aim for zero human-caused extinctions, how would this support a more resilient Earth for future generations of humans and animals alike?

Last week, I was joined by Peabody-award winning broadcaster Krista Tippett in an exploration of what it means to be human in our modern world and engage as individuals in the inner work required to create outward transformation.
