📖 Reading Passage

The concept of the 'Anthropocene' has gained significant traction in geological and environmental discourse, positing that human activity has become the dominant influence on the Earth's geology and ecosystems. 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 provide clear stratigraphic evidence. Critics, however, contend that the Anthropocene lacks a distinct and globally synchronous boundary, unlike previous epochs defined by natural transitions. Furthermore, some scholars question whether framing human impact as a geological event obscures the uneven responsibilities of different societies, as industrialized nations have contributed disproportionately to environmental change. This debate underscores the intersection of science, politics, and ethics in defining our current era.
