Brief summary
The Ends of the World in a nutshell
Peter Brannen takes readers on a fascinating journey through Earth's five previous mass extinction events, from the End-Ordovician extinction that killed 85% of marine species to the End-Cretaceous extinction that wiped out the dinosaurs. Drawing on cutting-edge paleontological and geological research, Brannen explores the causes of these ancient catastrophes—massive volcanic eruptions, asteroid impacts, rapid climate change, and ocean acidification—to provide crucial context for understanding the current biodiversity crisis.

Key ideas in The Ends of the World
Key idea 1
Earth has experienced five previous mass extinction events.
The history of life on Earth is a story of catastrophic loss followed by remarkable recovery, but the current extinction is fundamentally different.
Brannen documents each of Earth's previous mass extinctions: End-Ordovician (444 million years ago), Late Devonian (372-359 million years ago), Permian-Triassic (252 million years ago), Triassic-Jurassic (201 million years ago), and Cretaceous-Paleogene (66 million years ago). Each event had different causes but all resulted in massive loss of biodiversity, with the Permian-Triassic extinction killing up to 96% of marine species.
Remember
- Recognize that mass extinction is a recurring feature of Earth's history.
- Understand that different mechanisms have driven previous extinctions.
- Appreciate that recovery from mass extinctions takes millions of years.
Key idea 2
The Permian-Triassic extinction was the most severe in Earth's history.
The Great Dying was so severe that it almost ended life on Earth entirely.
The Permian-Triassic extinction, also known as "The Great Dying," was the closest life has ever come to complete annihilation. Caused by massive volcanic eruptions in Siberia that triggered rapid climate change, ocean acidification, and anoxia, this extinction killed up to 96% of marine species and 70% of terrestrial species. It took 10 million years for complex ecosystems to recover.
Remember
- Recognize that The Great Dying was nearly total biological annihilation.
- Understand how volcanic activity can trigger climate catastrophe.
- Appreciate the enormous timescales required for ecosystem recovery.
Key idea 3
The current extinction is unique in being caused by one species.
For the first time in Earth's history, a single species is causing a mass extinction.
Brannen emphasizes that while previous mass extinctions were caused by natural geological or astronomical events, the current extinction is being driven by human activities. This makes it unique in Earth's history—the first extinction caused by an intelligent species that is aware of what's happening. This uniqueness brings both responsibility and the possibility of prevention.
Remember
- Recognize that human agency makes this extinction unique in Earth's history.
- Understand that previous extinctions were caused by external forces.
- Appreciate that awareness gives us the ability to change course.
