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 nuclear fallout, plastic pollution, and elevated carbon dioxide levels provide clear stratigraphic signals. However, critics contend that the term oversimplifies the complex, uneven nature of human influence, which varies temporally and spatially. They also note that formalizing the epoch requires rigorous evidence of a global, synchronous boundary in the rock record, which remains elusive. This debate highlights broader tensions between scientific classification and societal narratives about environmental responsibility.
❓ Según el pasaje, ¿cuál es una razón principal por la que los críticos se oponen a formalizar el Antropoceno como una época geológica?
A. A) El término ignora los efectos positivos de la actividad humana sobre el medio ambiente.
B. B) La influencia humana en la Tierra carece de marcadores geológicos claros y globalmente consistentes.
C. C) La época propuesta es demasiado reciente para ser estudiada por geólogos.
D. D) La lluvia radiactiva y la contaminación por plásticos no son detectables en las capas de roca.
✅ 正确答案
B) Human influence on Earth lacks clear, globally consistent geological markers.
