The concept of the 'Anthropocene' has gained traction among geologists as a proposed new geological epoch defined by significant human impact on Earth's geology and ecosystems. Proponents argue that markers such as plastic pollution, nuclear fallout from atomic tests, and elevated carbon dioxide levels are distinctive enough to warrant a formal designation. However, critics contend that these changes, while profound, do not yet meet the strict criteria for a geological epoch, which traditionally requires a clear, global stratigraphic boundary visible in rock layers. They emphasize that the Holocene, the current interglacial period, already encompasses significant human activity, and defining a new epoch risks oversimplifying the complex interplay between natural and anthropogenic processes. This debate highlights the tension between scientific classification and the need to communicate urgent environmental concerns.

D. D. Si la contaminación por plásticos y la lluvia radiactiva son perjudiciales para los ecosistemas
✅ 正确答案
B. Whether the proposed markers meet the established criteria for a geological epoch
