Think Resilience Chapter 5: Pollution
May 9, 2017
In nature, waste from one organism is food for another. However, that principle sometimes breaks down and waste becomes poison. Humans aren’t the only possible sources of environmental pollution. But these days the vast majority of pollution does come from human activities. That’s because we humans are able to use energy and tools to extract, transform, use, and discard ever-larger quantities of natural resources, producing wastes of many kinds and in ever-larger quantities.
Here, Richard Heinberg explores the topic of pollution — in particular greenhouse gas emissions, which are the greatest threat to humans and other species.
This is the fifth video in our 22-part online course “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.
New chapters will be rolled out on a regular basis over the coming weeks, but you can also sign up to view all the videos right away.
