The concept of the 'Anthropocene' has gained traction among geologists as a proposed new geological epoch, characterized by significant human impact on Earth's geology and ecosystems. Unlike previous epochs, which were defined by natural climatic shifts or biological events, the Anthropocene is marked by the proliferation of synthetic materials, such as plastics and concrete, alongside dramatic changes in carbon and nitrogen cycles. While some scientists argue for its formalization based on distinct stratigraphic markers, others contend that human influence, though pervasive, does not yet constitute a clear boundary in the rock record. This debate highlights a broader tension between recognizing human agency in planetary change and adhering to traditional geological criteria.
