The concept of the 'Anthropocene' has gained traction among geologists as a proposed new geological epoch defined by human impact on Earth's systems. Unlike previous epochs, which were characterized by natural climatic shifts or biological events, the Anthropocene is marked by pervasive human activities such as nuclear testing, plastic pollution, and rapid urbanization. These markers, deposited in sediment and ice cores, provide a distinct stratigraphic signature. However, scholars debate its formalization, with some arguing that the term lacks a clear start date and oversimplifies the complex, uneven nature of human influence across regions and time periods. Proponents counter that the epoch's recognition is crucial for raising awareness and fostering interdisciplinary research on sustainability.
❓ According to the passage, what is a primary argument against formalizing the Anthropocene as a geological epoch?
A. A. The markers of human activity are not sufficiently distinct from natural events.
B. B. The term fails to acknowledge the varying degrees of human impact over time and space.
C. C. Nuclear testing and plastic pollution are not permanent enough to appear in geological records.
D. D. The concept has not gained any support among the scientific community.
✅ 正确答案
B. The term fails to acknowledge the varying degrees of human impact over time and space.
