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. Unlike previous epochs, which were characterized by natural climatic shifts or biological events, the Anthropocene is marked by human-induced changes such as nuclear fallout, plastic pollution, and accelerated species extinction. However, the formal recognition of this epoch remains contentious. Critics argue that human impacts are not synchronous globally, with different regions experiencing changes at different times, making a single global boundary difficult to establish. Proponents counter that markers like the radioactive isotopes from mid-20th-century nuclear tests provide a clear, worldwide signal. This debate highlights a deeper issue: whether geological classification should prioritize measurable physical evidence or acknowledge the unprecedented scale of human agency in shaping planetary processes.
❓ Según el pasaje, ¿cuál es la razón principal por la que algunos científicos se oponen al reconocimiento formal del Antropoceno como una época geológica?
A. Los impactos humanos no están distribuidos de manera uniforme en todo el mundo, lo que complica la identificación de una única fecha de inicio.
B. B) Los marcadores utilizados para definir la época, como la lluvia radiactiva nuclear, no son detectables en todas las regiones.
C. C) El concepto se centra demasiado en la agencia humana e ignora los procesos naturales.
D. D) La época propuesta no cuenta con suficiente evidencia física que respalde su existencia.
✅ 正确答案
A) Human impacts are not evenly distributed across the globe, complicating the identification of a single start date.
