📖 Reading Passage

The concept of the 'Anthropocene' has gained significant traction in geological and environmental circles, positing that human activities have become a dominant force shaping the Earth's systems. While the term remains informal in the geological timescale, its proponents argue that markers such as nuclear fallout, plastic pollution, and elevated carbon dioxide levels provide clear stratigraphic evidence. Critics, however, contend that the epoch is too recent and human impacts too diachronous to define a single global boundary. This debate underscores a broader tension between recognizing human influence on planetary processes and adhering to strict geological criteria, raising questions about how we classify our current era.
