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.
❓ According to the passage, why is the formal recognition of the Anthropocene as a geological epoch controversial?
A. A) Because human influence is not yet widespread enough to affect global ecosystems.
B. B) Because some scientists believe it lacks a clear stratigraphic marker comparable to past epochs.
C. C) Because the term is only used in cultural and political contexts, not in geology.
D. D) Because volcanic activity and asteroid impacts are still the primary forces shaping the Earth.
✅ 正确答案
B) Because some scientists believe it lacks a clear stratigraphic marker comparable to past epochs.
