The concept of the 'Anthropocene' has gained traction among geologists and environmental scientists as a proposed geological epoch defined by significant human impact on Earth's geology and ecosystems. Unlike previous epochs, which were shaped by natural forces such as volcanic activity or asteroid impacts, the Anthropocene is characterized by markers like plastic pollution, nuclear fallout, and elevated greenhouse gas levels. However, the formal recognition of this epoch remains contentious. Some scholars argue that human influence has been too gradual and diachronous to constitute a clear boundary in the stratigraphic record, while others contend that the mid-20th century 'Great Acceleration' provides a distinct and globally synchronous signal. This debate highlights broader questions about how we define time and our role in shaping planetary history.
❓ Según el pasaje, ¿cuál es una razón principal de la controversia en torno al reconocimiento formal del Antropoceno?
A. A. El impacto humano ha sido demasiado rápido y uniforme como para dejar marcadores geológicos claros.
B. B. Los marcadores propuestos, como la contaminación por plásticos, no se encuentran en todas las regiones.
C. C. Algunos científicos creen que la influencia humana carece de un límite estratigráfico claro y sincrónico a nivel global.
D. D. La 'Gran Aceleración' ocurrió demasiado temprano en la historia humana como para ser relevante.
✅ 正确答案
C. Some scientists believe human influence lacks a clear, globally synchronous stratigraphic boundary.
