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. Proponents argue that markers such as plastic pollution, nuclear fallout, and elevated carbon dioxide levels provide clear stratigraphic evidence of human influence. However, critics contend that the term is more cultural than scientific, noting that human activity lacks a single, synchronous global boundary layer comparable to previous epoch transitions. This debate highlights a broader tension between scientific classification and societal narrative, as naming an epoch carries implications for how we perceive our responsibility toward the planet's future.
❓ According to the passage, what is the main reason critics reject the Anthropocene as a formal geological epoch?
A. Human impact is not significant enough to alter geological strata.
B. There is no consistent worldwide marker that aligns with a single time boundary.
C. The term is purely political and has no scientific basis.
D. Geological epochs cannot be defined by human-induced changes.
✅ 正确答案
There is no consistent worldwide marker that aligns with a single time boundary.
