📖 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 shaped by natural forces such as volcanic activity or asteroid impacts, the Anthropocene is characterized by human-driven changes, including nuclear fallout, plastic pollution, and accelerated carbon emissions. However, the formal recognition of this epoch remains contentious. Critics argue that human impacts are not yet stratigraphically distinct enough to mark a clear boundary in the rock record, whereas proponents contend that the rapid and irreversible changes justify a new classification. This debate highlights a fundamental tension between geological precision and the urgency of conveying human influence on planetary systems.
