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 marked by natural events such as ice ages 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 scientists argue that the changes are so profound and rapid that they warrant a distinct stratigraphic boundary, while others contend that human influence, though substantial, has not yet produced a globally synchronous and permanent signal in the rock record. This debate highlights the challenge of integrating human history with deep geological time, forcing a reconsideration of how we define and divide the planet's history.

B. B. 대부분의 지질학자들은 인간의 영향이 지질 구조에 영향을 미치기에는 너무 사소하다고 믿는다.
C. C. '인류세'라는 용어는 비과학자들에 의해 만들어졌으며 과학적 근거가 부족하다.
D. D. 인간에 의해 발생한 변화는 암석 기록에서 관찰하기에는 너무 느리다.
✅ 正确答案
