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. Proponents argue that markers such as nuclear fallout, plastic pollution, and elevated carbon dioxide levels provide clear stratigraphic evidence of human activity. However, critics contend that the term is more cultural than scientific, noting that the formal recognition of an epoch requires globally synchronous and long-lasting geological signatures, which current human-induced changes may not fully satisfy. This debate highlights the intersection of scientific classification and societal awareness, raising questions about how we define and respond to our planetary influence.
❓ According to the passage, what is a primary reason some critics oppose the formal recognition of the Anthropocene as a geological epoch?
A. A. Human-induced changes are not yet visible in geological records.
B. B. The proposed markers lack global synchrony and long-term geological persistence.
C. C. Nuclear fallout and plastic pollution are too minor to be significant.
D. D. The term has been rejected by all geologists and environmental scientists.
✅ 正确答案
B. The proposed markers lack global synchrony and long-term geological persistence.
