📖 Reading Passage

The concept of the 'Anthropocene' has gained traction among geologists as a proposed new geological epoch, characterized by significant human impact on Earth's geology and ecosystems. Unlike previous epochs, which were defined by natural climate shifts and biological evolution, the Anthropocene is marked by human-induced changes such as nuclear fallout, plastic pollution, and elevated carbon dioxide levels. Proponents argue that these markers are stratigraphically distinct and will be preserved in the rock record, justifying a formal designation. However, skeptics contend that the term is more cultural than scientific, noting that human activities have altered the environment for millennia, and that the proposed markers may not be globally synchronous. This debate underscores the challenge of defining geological time in an era of rapid planetary change, raising questions about the intersection of science, policy, and human responsibility.
