What We Do

8 Billion Angels



Earth Overshoot Founder Exposes the Primary Driver of Ecological Overshoot in Documentary

Global warming, food and water shortages, catastrophic storms, extinction of species, plant and animal habitat loss…. The list of environmental, social and economic catastrophes affecting our planet with greater frequency and severity goes on and on. If there was a simple root cause and a fundamental solution, wouldn’t you want to know?

Enter Earth Overshoot Founder Terry Spahr and his 8 Billion Angels team to do what most of the world has yet to do: connect the dots among all of the “downstream” symptoms of our global environmental crises with their fundamental upstream cause- overpopulation.

8 Billion uses breathtaking photography and startling emotion to show how mankind’s incredible success, as measured in numbers and consumption, could ultimately undo us all.

8 Billion Angels eschews political correctness for an honest assessment and real solution. Most importantly, the film arrives at a critical moment with an honest assessment and real solutions while there’s still a chance to save our planet and our species by quickly and dramatically altering our population and consumption trajectories.
