The concept of the 'Anthropocene' has gained significant traction in geological and environmental circles, though its formal recognition as a new epoch remains a subject of debate. Proponents argue that human activities, particularly since the mid-20th century, have left unmistakable markers in the stratigraphic record, such as radioactive isotopes from nuclear tests, microplastics, and elevated carbon dioxide levels. These markers, they contend, justify a distinct geological boundary. Conversely, skeptics point out that the term lacks the temporal depth of formal geological epochs, which typically span millions of years. They also question whether human impacts are truly global and synchronous, noting that geological boundaries require a clear, worldwide signal. Despite these disagreements, the Anthropocene concept has proven valuable as a heuristic device, prompting interdisciplinary research into human-environment interactions and fostering a broader dialogue about sustainability and planetary stewardship.
❓ Según el pasaje, ¿cuál es la razón principal por la que algunos geólogos se oponen a reconocer formalmente el Antropoceno como una nueva época?
A. A. Los impactos humanos aún no son visibles en el registro geológico.
B. B. La época propuesta no cumple con los criterios temporales y globales de las épocas geológicas formales.
C. C. El término 'Antropoceno' es demasiado difícil de entender para los no científicos.
D. D. No hay evidencia de cambios ambientales causados por el ser humano.
✅ 正确答案
B. The proposed epoch does not meet the temporal and global criteria of formal geological epochs.
