📖 Reading Passage

The concept of the 'Anthropocene' has gained traction among geologists and environmental scientists as a proposed new geological epoch characterized by significant human impact on Earth's geology and ecosystems. Proponents argue that markers such as plastic pollution, nuclear fallout, and elevated carbon dioxide levels provide clear stratigraphic evidence of human influence. However, critics contend that the term is more cultural than scientific, pointing to the difficulty of defining a precise start date, with suggestions ranging from the advent of agriculture to the mid-20th century. They also note that geological epochs typically span millions of years, whereas human impact, though profound, is relatively recent. This debate highlights the tension between scientific classification and the urgency of environmental advocacy, raising questions about how we formalize our current era.
