Chapter 2 - Mass Extinction Events

Chapter Summary

The passage explores past mass extinctions, such as the event that wiped out the dinosaurs and the Permian-Triassic event, the most severe extinction in history. These were caused by natural disasters like asteroid impacts and volcanic eruptions.

The text then shifts to the Anthropocene, a sixth mass extinction that is caused by humans. Our impact on the planet is now so deep and pervasive that we now have the dubious honour of having a slice of Geological time named after us. Our relentless consumption-driven biodiversity loss destabilised the natural balance of climate systems and polluted multiple layers of the environment.

To illustrate our fleeting existence in Earth’s timeline, a 24-hour clock analogy shows humans arriving mere seconds before midnight. A fact that underlines both our fragility as a civilization and our extraordinary capacity to affect change.

Finally, given our reckless overconsumption, the chapter playfully questions whether we truly deserve the title "Homo sapiens" — wise humans. This sets the stage for deeper discussions on responsibility and solutions in later chapters.
