The concept of the 'Anthropocene' has gained traction among geologists as a proposed new geological epoch defined by human impact on Earth's systems. Unlike previous epochs, which were characterized by natural climatic shifts or biological events, the Anthropocene is marked by pervasive human activities such as nuclear testing, plastic pollution, and rapid urbanization. These markers, deposited in sediment and ice cores, provide a distinct stratigraphic signature. However, scholars debate its formalization, with some arguing that the term lacks a clear start date and oversimplifies the complex, uneven nature of human influence across regions and time periods. Proponents counter that the epoch's recognition is crucial for raising awareness and fostering interdisciplinary research on sustainability.
❓ Según el pasaje, ¿cuál es un argumento principal en contra de formalizar el Antropoceno como una época geológica?
A. A. Los marcadores de la actividad humana no son suficientemente distintos de los eventos naturales.
B. B. El término no reconoce los distintos grados de impacto humano a lo largo del tiempo y del espacio.
C. C. Las pruebas nucleares y la contaminación por plásticos no son lo suficientemente permanentes como para aparecer en los registros geológicos.
D. D. El concepto no ha obtenido ningún apoyo entre la comunidad científica.
✅ 正确答案
B. The term fails to acknowledge the varying degrees of human impact over time and space.
