The concept of the 'Anthropocene' has gained significant traction in recent decades, positing that human activities have become the dominant force shaping Earth's geology and ecosystems. While the term was popularized by atmospheric chemist Paul Crutzen in 2000, its formal recognition as a geological epoch remains debated among scientists. Proponents argue that markers such as nuclear fallout, plastic pollution, and elevated carbon dioxide levels provide clear stratigraphic evidence of a distinct human-driven era. However, skeptics contend that these signals are too variable and recent to meet the strict criteria for a geological time unit, which typically spans thousands or millions of years. This debate underscores a deeper tension between scientific classification and the urgency of addressing human impact on the planet.
❓ Según el pasaje, ¿cuál es la razón principal por la que algunos científicos se oponen al reconocimiento formal del Antropoceno como una época geológica?
A. A. Las actividades humanas no han causado ningún cambio permanente en el medio ambiente.
B. B. La evidencia del impacto humano es demasiado inconsistente y de corto plazo para ajustarse a los estándares geológicos.
C. C. El término fue popularizado por un solo científico sin una revisión por pares suficiente.
D. D. La lluvia radiactiva nuclear y la contaminación por plásticos no son detectables en los registros geológicos.
✅ 正确答案
B. The evidence of human impact is too inconsistent and short-term to fit geological standards.
