📖 Reading Passage

The concept of the 'Anthropocene' has gained significant traction in geological and environmental circles, referring to the current epoch in which human activities have become the dominant influence on the Earth's climate and ecosystems. While the term remains unofficial in the geological timescale, its proponents argue that markers such as nuclear fallout, plastic pollution, and elevated carbon dioxide levels provide clear stratigraphic evidence of a distinct human-driven era. Critics, however, contend that the Anthropocene lacks a precise starting point and that its boundaries are too diffuse to qualify as a formal geological period. Despite this debate, the term serves a crucial rhetorical purpose: it underscores the unprecedented scale and irreversibility of human impact, urging a re-evaluation of humanity's role as a geological agent rather than merely a biological one.
