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 lacks precise temporal boundaries, as human influence has been gradual rather than abrupt, and that formalizing such an epoch may oversimplify the complex interactions between natural and anthropogenic processes. Despite this debate, the Anthropocene concept has proven valuable beyond geology, fostering interdisciplinary dialogue about humanity's role in shaping planetary systems and informing policy discussions on sustainability. Thus, while its geological status remains contested, its heuristic power in highlighting the scale of human impact is widely acknowledged.
❓ Según el pasaje, ¿cuál es una razón principal por la que algunos científicos se oponen a formalizar el Antropoceno como una época geológica?
A. A. Los marcadores de la actividad humana no son lo suficientemente distintivos como para ser identificados en las capas de roca.
B. B. El concepto ha estado demasiado influenciado por agendas políticas en lugar de evidencia científica.
C. C. La influencia humana sobre la Tierra ha sido gradual, lo que dificulta definir un punto de partida claro.
D. D. El término no ha ganado suficiente popularidad entre los científicos ambientales.
✅ 正确答案
C. Human influence on Earth has been gradual, making it difficult to define a clear starting point.
