📖 Reading Passage

The concept of the 'Anthropocene' has gained significant traction in geological and environmental circles, referring to the current epoch in which human activity has become the dominant influence on the Earth's climate and ecosystems. While the term was popularized by atmospheric chemist Paul Crutzen in 2000, its formal recognition as a geological epoch remains contested. Proponents argue that markers such as nuclear fallout, plastic pollution, and elevated carbon dioxide levels provide clear stratigraphic evidence of human impact. Critics, however, contend that these signatures are too variable and recent to define a distinct epoch, suggesting instead that the term 'Anthropocene' is more useful as a cultural or historical concept. This debate highlights a fundamental tension between scientific classification and the broader implications of human agency on planetary processes.
