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 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. However, the formal recognition of this epoch remains contentious. Critics argue that human influence, while profound, lacks the global stratigraphic distinctiveness required for a formal geological boundary. Proponents counter that the unprecedented scale and synchrony of human-induced changes justify a distinct epoch, urging a redefinition of humanity's role in planetary history.
❓ 지문에 따르면, 인류세의 공식적 인정을 둘러싼 논란의 주된 이유는 무엇인가?
A. A. 제안된 지표들, 예를 들어 핵 낙진과 플라스틱 오염 같은 것들은 너무 최근의 것이어서 지질학적 기록에 보존되기에는 부족하다.
B. B. 일부 과학자들은 인간의 영향이 뚜렷한 층서 경계의 기준을 충족하지 못한다고 믿는다.
C. C. 인류세(Anthropocene)의 개념은 자연적 사건에 기반한 전통적인 지질 시대 구분에 도전을 제기한다.
D. D. 인간에 의한 변화가 지구적 규모에서 새로운 시대를 뒷받침할 만한 충분한 증거가 부족하다.
✅ 正确答案
B. Some scientists believe that human impact does not meet the criteria for a distinct stratigraphic boundary.
