The History of Earth's Five Mass Extinction Events

This documentary explores the five great mass extinctions that have punctuated Earth's history, and asks whether humans are driving a sixth. With the background extinction rate now far above normal, it examines the deep past for warnings about the present. The film connects ancient catastrophes to the changes our species is imposing on the planet. It is a sobering, fascinating watch for anyone concerned about life's fragility.
