The concept of the 'Anthropocene' has gained significant traction in geological and environmental circles, proposing that human activity has become a dominant force shaping the Earth's systems. Unlike previous geological epochs, which were defined by natural phenomena such as ice ages or asteroid impacts, the Anthropocene is characterized by markers like plastic pollution, nuclear fallout, and a dramatic spike in carbon dioxide levels. However, the formal recognition of this epoch remains contentious. Some scientists argue that the changes are too recent and not yet fully stratified in the geological record, while others contend that the scale and irreversibility of human impact warrant a distinct epoch. This debate underscores a deeper question: whether human influence has truly pushed the planet into a new geological reality, or whether we are merely witnessing an accelerated phase of a longer natural cycle.

C. C. El concepto de Antropoceno entra en conflicto con la idea de épocas geológicas naturales como las glaciaciones.
D. D. No hay evidencia de que la actividad humana haya alterado los niveles de dióxido de carbono a escala global.
✅ 正确答案
B. Some experts doubt that human-induced changes are sufficiently recent and clearly recorded in geological layers.
