The concept of the 'Anthropocene' has gained traction among geologists and environmental scientists as a proposed new geological epoch defined by significant human impact on Earth's geology and ecosystems. Proponents argue that markers such as plastic pollution, nuclear fallout, and accelerated species extinction clearly distinguish this period from the Holocene, which began about 11,700 years ago. However, critics contend that the term is more cultural than scientific, as the human footprint is not uniform across time or space, and formalizing it may oversimplify complex natural processes. This debate underscores the challenge of integrating human agency into geological classification systems that traditionally rely on natural, stratigraphic evidence.
❓ Según el pasaje, ¿cuál es la razón principal por la que algunos científicos se oponen a formalizar el Antropoceno como una época geológica?
A. A. La evidencia del impacto humano es demasiado escasa para ser medida.
B. B. El concepto se basa en marcadores culturales más que en evidencia natural consistente.
C. C. La época del Holoceno ya ha terminado y no puede ser comparada.
D. D. Las actividades humanas aún no han causado cambios ambientales significativos.
✅ 正确答案
B. The concept relies on cultural markers rather than consistent natural evidence.
