The concept of the 'Anthropocene' has gained traction among geologists as a proposed new geological epoch defined by humanity's profound impact on Earth's systems. Unlike previous epochs, which were delineated by natural climatic shifts or biological events, the Anthropocene is characterized by markers such as nuclear fallout, plastic pollution, and elevated carbon dioxide levels. However, the proposal remains contentious. Some scientists argue that the term should be formalized to reflect the scale of human-induced change, while others contend that the changes are not yet synchronous across the globe, failing to meet the strict criteria of a geological time unit. This debate underscores a deeper tension between scientific classification and the recognition of human agency in shaping planetary history.
❓ According to the passage, what is a primary reason some scientists oppose formalizing the Anthropocene as a geological epoch?
A. A. The markers used to define it are not universally agreed upon.
B. B. Human-induced changes are not occurring simultaneously worldwide.
C. C. Nuclear fallout and plastic pollution are too recent to study.
D. D. The concept ignores natural climatic shifts from previous epochs.
✅ 正确答案
B. Human-induced changes are not occurring simultaneously worldwide.
