The concept of the 'Anthropocene' has gained traction among geologists and environmental scientists as a proposed new geological epoch defined by significant human impact on Earth's geology and ecosystems. Unlike previous epochs, which were characterized by natural climatic shifts or biological events, the Anthropocene is marked by human-induced changes such as nuclear fallout, plastic pollution, and accelerated species extinction. Proponents argue that these markers are distinct enough to warrant a formal boundary, while critics contend that human activities are too diachronous and variable to define a single, clear-cut geological layer. This debate underscores a fundamental tension between stratigraphic precision and the broader narrative of human influence, raising questions about how science defines time and responsibility.
