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 anthropogenic markers including plastic pollution, elevated carbon dioxide levels, and the global dispersal of radioactive isotopes from nuclear tests. Proponents argue that these markers are distinct and persistent enough to warrant a formal boundary in the geological timescale. However, critics contend that the term oversimplifies the complex and uneven nature of human influence, suggesting that a more nuanced framework is needed to address regional variations in environmental change. This debate underscores the broader challenge of integrating scientific evidence with societal narratives about human responsibility for the planet's future.
❓ Según el pasaje, ¿cuál es un argumento clave planteado por los críticos del concepto de Antropoceno?
A. A) El impacto humano en la Tierra no es lo suficientemente significativo como para definir una nueva época geológica.
B. B) El concepto no logra tener en cuenta la variabilidad y complejidad de la influencia humana en las distintas regiones.
C. C) Los isótopos radiactivos no son marcadores fiables de la actividad humana.
D. D) La escala de tiempo geológico debería revisarse para incluir más fuerzas naturales.
✅ 正确答案
B) The concept fails to account for the variability and complexity of human influence across regions.
IELTS Reading Tips
Skim the questions first, underline keywords, then locate in the passage
Watch for paraphrasing; correct answers are often reworded
Be wary of absolute statements (all, always, never) — usually wrong
Pay attention to content after transition words (however, but, yet)
