The concept of the 'Anthropocene' has gained traction among geologists as a proposed new geological epoch defined by human impact on Earth's systems. Unlike earlier epochs, which were characterized by natural climatic shifts or biological events, the Anthropocene is marked by pervasive changes such as nuclear fallout, plastic pollution, and accelerated species extinction. However, scholars debate its starting point: some argue for the Industrial Revolution, while others point to the mid-20th century 'Great Acceleration.' This ambiguity raises questions about how we define geological time and whether human activity can be compared to natural forces in scale and permanence.
