📖 Reading Passage

The concept of the 'Anthropocene' has gained significant traction in geological and environmental discourse, positing that human activities have become a dominant force shaping Earth's systems. While the term was popularized by atmospheric chemist Paul Crutzen in 2000, its formal recognition as a geological epoch remains contentious. Proponents argue that markers such as plastic pollution, nuclear fallout, and elevated carbon dioxide levels constitute a distinct stratigraphic signature. However, critics contend that the Anthropocene lacks a clear, synchronous beginning, unlike formal epochs which are defined by global, abrupt transitions in rock layers. This debate highlights a fundamental tension: whether geological classification should reflect planetary-scale human impact or adhere strictly to traditional stratigraphic criteria. The resolution of this issue carries implications beyond geology, influencing how societies perceive their environmental responsibilities and historical narrative.
