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. Unlike previous epochs, which were delineated by natural climatic shifts or biological events, the Anthropocene is characterized by markers such as nuclear fallout, plastic pollution, and elevated carbon dioxide levels. Proponents argue that these markers are stratigraphically distinct and globally synchronous, warranting formal recognition. However, critics contend that the term is more cultural than scientific, noting that human activities have altered the environment for millennia, and that the proposed markers lack the long-term durability of natural geological boundaries. This debate underscores the tension between scientific classification and societal narratives about human responsibility for planetary change.
❓ Según el pasaje, ¿cuál es una razón principal por la que algunos críticos se oponen a formalizar el Antropoceno como una época geológica?
A. El impacto humano en el medio ambiente ha estado ocurriendo durante mucho tiempo y no es algo nuevo.
B. B) Los marcadores propuestos no están lo suficientemente extendidos a nivel mundial como para ser útiles.
C. C) El término se centra demasiado en los cambios climáticos naturales en lugar de en la actividad humana.
D. D) Los científicos coinciden en que la lluvia radiactiva es el único indicador fiable.
✅ 正确答案
A) Human impact on the environment has been occurring for a very long time and is not new.
