The concept of the 'Anthropocene' has gained traction among geologists 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 anthropogenic markers including radioactive isotopes from nuclear tests, plastic pollution, and elevated carbon dioxide levels. However, the formal recognition of this epoch remains contentious. Some scholars argue that human influence, while pervasive, does not yet represent a distinct stratigraphic boundary comparable to those of the Pleistocene-Holocene transition. Others contend that the scale and irreversibility of changes, such as biodiversity loss and climate alteration, justify a new epoch. This debate underscores a broader challenge in stratigraphy: balancing geological precision with the need to communicate planetary-scale changes.
❓ 인류세(Anthropocene)를 지질학적 시대로 공식 인정하는 것에 대한 논란의 주요 원인은 무엇인가?
A. A. 인간의 영향은 아직 지질학적 기록에서 감지되지 않는다.
B. B. 일부 학자들은 인간이 유발한 변화가 별개의 층서학적 경계 기준을 충족하는지 의문을 제기한다.
C. C. 이 시기는 방사성 동위원소나 플라스틱 오염과 같은 명확한 지표가 부족하다.
D. D. 지질학자들은 자연적 힘이 여전히 지질학적 변화의 주요 동인이라는 데 동의한다.
✅ 正确答案
B. Some scholars question whether human-induced changes meet the criteria for a distinct stratigraphic boundary.
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)
