📖 Reading Passage

The concept of the 'Anthropocene' has gained traction among geologists and environmental scientists as a proposed new geological epoch defined by significant human impact on Earth's geology and ecosystems. Unlike previous epochs, which were delineated by natural climatic shifts or biological events, the Anthropocene is characterized by markers such as nuclear fallout, plastic pollution, and elevated carbon dioxide levels. Proponents argue that these markers are stratigraphically distinct and globally synchronous, warranting formal recognition. However, critics contend that the term is more cultural than scientific, noting that human activities have altered the environment for millennia, and that the proposed markers lack the long-term durability of natural geological boundaries. This debate underscores the tension between scientific classification and societal narratives about human responsibility for planetary change.
