The concept of the 'Anthropocene' has gained traction among geologists and environmental scientists as a proposed 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, nuclear fallout, and elevated greenhouse gas levels. However, the formal recognition of this epoch remains contentious. Some scholars argue that human influence has been too gradual and diachronous to constitute a clear boundary in the stratigraphic record, while others contend that the mid-20th century 'Great Acceleration' provides a distinct and globally synchronous signal. This debate highlights broader questions about how we define time and our role in shaping planetary history.
❓ According to the passage, what is a primary reason for the controversy surrounding the formal recognition of the Anthropocene?
A. A. Human impact has been too rapid and uniform to leave clear geological markers.
B. B. The proposed markers, such as plastic pollution, are not found in all regions.
C. C. Some scientists believe human influence lacks a clear, globally synchronous stratigraphic boundary.
D. D. The 'Great Acceleration' occurred too early in human history to be relevant.
✅ 正确答案
C. Some scientists believe human influence lacks a clear, globally synchronous stratigraphic boundary.
