📖 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 contentious. 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 the Anthropocene lacks a distinct starting point, with some suggesting the Industrial Revolution and others pointing to the advent of agriculture. This debate underscores a deeper question: whether humanity's footprint is a sudden rupture or a gradual transformation of the planet's history.
