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.
❓ Según el pasaje, ¿cuál es una razón principal por la que algunos críticos se oponen al reconocimiento formal del Antropoceno como una época geológica?
A. A. Los cambios inducidos por el ser humano aún no son visibles en los registros geológicos.
B. B. Los marcadores propuestos carecen de sincronía global y persistencia geológica a largo plazo.
C. C. La lluvia radiactiva y la contaminación por plásticos son demasiado menores para ser significativas.
D. D. El término ha sido rechazado por todos los geólogos y científicos ambientales.
✅ 正确答案
B. The proposed markers lack global synchrony and long-term geological persistence.
