The concept of the 'Anthropocene' has gained traction among geologists as a proposed new geological epoch, characterized by significant human impact on Earth's geology and ecosystems. Proponents argue that markers such as plastic pollution, nuclear fallout, and elevated carbon dioxide levels provide clear stratigraphic evidence of human activity. However, critics contend that these markers are not yet globally synchronous or long-lasting enough to define a distinct epoch, suggesting instead that the term 'Anthropocene' should remain a cultural or historical designation rather than a formal geological unit. This debate highlights the tension between scientific rigor and the need to communicate humanity's profound influence on the planet.
❓ ¿Cuál es el principal punto de controversia respecto al 'Antropoceno' tal como se describe en el pasaje?
A. Si el impacto humano es lo suficientemente significativo como para alterar los procesos geológicos
B. Si los marcadores propuestos son suficientes y apropiados para definir una nueva época geológica.
C. Si el término debe utilizarse en el discurso público sobre el cambio ambiental
D. Si la contaminación por plásticos es un marcador más fiable que la lluvia radiactiva nuclear.
✅ 正确答案
Whether the proposed markers are sufficient and appropriate to define a new geological epoch
