📖 Reading Passage

The concept of the 'Anthropocene' has gained traction among geologists as a proposed new geological epoch, defined by humanity's profound impact on Earth's systems. Proponents argue that markers such as radioactive fallout from nuclear tests, plastic pollution, and elevated carbon dioxide levels provide clear stratigraphic evidence. However, critics contend that the term oversimplifies complex planetary changes and that the proposed markers do not align with the traditional timescales of geological epochs, which typically span millions of years. This debate highlights a fundamental tension between scientific classification and the urgent need to address environmental crises, as naming a new epoch could either galvanize policy action or, conversely, diminish the significance of human influence by framing it as merely another geological transition.
