Human activities have altered the planet so significantly that scientists propose we have entered a new geological epoch: the Anthropocene. To confirm this, an extensive scientific investigation has taken place over five years, involving research teams from around the world. This documentary follows their efforts to gather evidence, examining how human impact on Earth's ecosystems, climate, and geology compares to natural processes. Through fieldwork, data collection, and analysis, the research aims to define the boundaries of this new epoch and understand its long-term consequences. The film explores the implications of this shift and what it means for the planet’s future.
