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.

C. C) 因为这个术语仅用于文化和政治语境中,而非地质学领域。
D. D)因为火山活动和小行星撞击仍然是塑造地球的主要力量。
✅ 正确答案
B) Because some scientists believe it lacks a clear stratigraphic marker comparable to past epochs.
