Humans have become so powerful a force that we're now leaving a permanent mark in the rock record itself — from plastics and concrete to nuclear traces and shifted carbon. That idea gave rise to the “Anthropocene,” a proposed new chapter of geological time named for us. This final episode of the series explores what it means to become a planetary force, why the term is scientifically debated, and what it says about our responsibilities.

You'll come away understanding how geologists divide time, what evidence suggests humans are leaving a lasting signal, why the Anthropocene has not been formally adopted as an official epoch, and why the underlying idea matters regardless of the label.
