Think Resilience Lesson 4: Depletion

By Richard Heinberg, originally published by Resilience.org

April 25, 2017

Post Carbon Institute Senior Fellow Richard Heinberg sat down to deliver a 22-chapter lecture series entitled “Think Resilience: Preparing Communities for the Rest of the 21st Century,” which explores how communities can build resilience in the face of our intertwined sustainability crises. The series is intended for students and concerned individuals of all ages.

Chapter 4: Depletion

Depletion is an inescapable fact of life: As soon as you’ve taken one sip of your coffee, or one bite of ice cream, you’ve begun to deplete that resource. Economists will tell you, “No problem. You can just run to the store and buy more, or find something else just as good as a substitute.” But does that work on a finite planet, and are all resources so easily substitutable?

Here Richard Heinberg explores the topic of depletion and why it matters so much — to our well-being today and the future of humanity and the planet tomorrow.
