The concept of the 'Anthropocene' has gained significant traction among geologists and environmental scientists as a proposed new geological epoch, defined by the profound and lasting impact of human activities on the Earth's systems. Proponents argue that markers such as nuclear fallout from atomic tests, plastic pollution, and elevated carbon dioxide levels are stratigraphically distinct and will be visible in the rock record for millions of years. However, critics contend that the term is more culturally and politically charged than scientifically precise, noting that human-induced changes occur at varying rates across different regions and that the formal criteria for an epoch, such as a clear global boundary, are not yet fully met. This debate underscores a deeper tension between the desire for a clear narrative of planetary change and the complex, uneven realities of geological evidence.
❓ According to the passage, what is a primary reason why some scientists oppose the formal recognition of the Anthropocene as a geological epoch?
A. A. Human activities have not yet caused any significant changes to the Earth's systems.
B. B. The proposed markers, such as plastic pollution, are not globally distributed.
C. C. The geological evidence for human impact lacks a consistent global boundary.
D. D. The term is too scientific and excludes cultural and political perspectives.
✅ 正确答案
C. The geological evidence for human impact lacks a consistent global boundary.
