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. 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. Proponents argue that these markers are stratigraphically distinct and globally synchronous, warranting formal recognition. However, critics contend that the term is more cultural than scientific, noting that human activities have altered the environment for millennia, and that the proposed markers lack the long-term durability of natural geological boundaries. This debate underscores the tension between scientific classification and societal narratives about human responsibility for planetary change.
❓ According to the passage, what is a main reason some critics oppose formalizing the Anthropocene as a geological epoch?
A. A) Human impact on the environment has been occurring for a very long time and is not new.
B. B) The proposed markers are not globally widespread enough to be useful.
C. C) The term is too focused on natural climatic shifts rather than human activity.
D. D) Scientists agree that nuclear fallout is the only reliable indicator.
✅ 正确答案
A) Human impact on the environment has been occurring for a very long time and is not new.
