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 shaped by natural forces such as volcanic activity or asteroid impacts, the Anthropocene is characterized by markers like plastic pollution, radioactive fallout from nuclear tests, and elevated carbon dioxide levels. However, the formal recognition of this epoch remains contentious, as some scholars argue that human influence, while pervasive, has not yet produced a distinct stratigraphic signal comparable to that of earlier transitions. Others contend that the term itself is useful beyond geology, serving as a cultural and political catalyst for discussions on sustainability and planetary stewardship. This debate highlights the intersection of scientific classification and societal values, raising questions about how we define boundaries in both time and responsibility.
❓ Según el pasaje, ¿por qué es controvertido el reconocimiento formal del Antropoceno como una época geológica?
A. A) Porque la influencia humana aún no es lo suficientemente generalizada como para afectar los ecosistemas globales.
B. B) Porque algunos científicos creen que carece de un marcador estratigráfico claro comparable al de épocas pasadas.
C. C) Porque el término solo se utiliza en contextos culturales y políticos, no en geología.
D. D) Porque la actividad volcánica y los impactos de asteroides siguen siendo las fuerzas principales que moldean la Tierra.
✅ 正确答案
B) Because some scientists believe it lacks a clear stratigraphic marker comparable to past epochs.
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)
