Earth Overshoot has been a guest on numerous podcasts, initiating a dialogue about the role of our global population in environmental emergencies such as climate change, aquifer depletion, deforestation and species extinction and offering practical, proven and research-backed solutions for individuals around the world to help bring our planet back into balance. 


Terry Spahr, Executive Director of Earth Overshoot interviews economists about fascinating new data upending long held beliefs.

For the first time in modern history, a handful of countries are witnessing actual population declines. The data is now available to separate reality from what has heretofore been baseless theory.

Guest-host for the Growth Busters podcast, Terry Spahr, speaks with the study’s authors to illuminate their findings that dispel the firmly entrenched false notion that endless population growth is the only path to economic salvation.



Why Living on Less Is So Hard

Filmmaker, environmental activist and Executive Director of Earth Overshoot Terry Spahr recently appeared on Population Media Center’s “Population 8 Billion” podcast. During this revealing discussion hosted by Veronika Perkova, Terry unpacks the immutable and often overlooked connection between consumption and our financial system and its consequences.  




Podcast host Veronika Perková created Nature Solutionaries to support inspirational conservationists and encourage listeners to do something good for nature. In this episode she interviews Terry Spahr, the environmentalist and producer behind the documentary 8 BILLION ANGELS. They talk about:

  • how population growth impacts our lives, health, and the planet
  • why so few people talk about overpopulation and why some even deny it
  • why having a smaller family is the most impactful thing anyone can do
  • why providing access to education and family planning methods helps both people and nature
  • which countries are successfully slowing population growth
  • why reducing consumption is almost impossible
  • why educating people about population is part of the solution

On a recent episode of her podcast, Conservation: The New Normal Is Take the Road Less Traveled, she spoke with 8 Billion Angels producer and Earth Overshoot's Executive Director Terry Spahr about his decision to take the road less traveled and confront the "taboo" of our unsustainable population growth as a chief driver of climate change and many more of our environmental emergencies.

Lurking in the near-background behind every environmental story is one shared truth: We are running a grand experiment on planet Earth and there are simply too many people on it. The solution? That's where it gets tricky. Join the Green Radio Hour with Jon Bowermaster for a conversation with two who have studied the issue for decades, Earth Overshoot's Terry Spahr and Don Weeden. And check out Terry's new documentary, '8 Billion Angels,' coming soon to a streaming channel near you.

"Harnessing the Power of We" Podcast with Earth Overshoot's Terry Spahr

What does sustainability mean in a world of almost 8 billion people?

The Earth tells us it's in trouble in a number of ways -- things like changing disease vectors that are really surprising and harmful, food and water insecurity, and mass starvation. Why are we increasingly experiencing things that are hard for humans to recover from?

Earth Overshoot Founder Terry Spahr talked with WGCO Chicago's Mike Nowack about the outsize role population plays in our environmental emergencies and how we have the power to achieve global sustainability.

Do You Want to Be Politically Correct or Save the Environment? Terry Spahr Speaks With Green Dreamer

"If you care more about the environment than political correctness, then we have to come together as cheerleaders for a better, safer, less crowded, and more sustainable world."

On this podcast episode, Terry sheds light on what a truly sustainable lifestyle with seven billion people on earth should really look like; why population growth has been the elephant in the room that needs to be discussed more openly as a solution to lessening our environmental impact; how we can work with the nuance that people in "developing countries" have less of an ecological footprint compared to those living in "developed countries"; and more.
