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. Unlike previous epochs, which were delineated by natural climatic shifts or biological events, the Anthropocene is characterized by markers such as nuclear fallout, plastic pollution, and elevated carbon dioxide levels. However, the formal recognition of this epoch remains contentious. Critics argue that human influence, while profound, is not yet comparable to the deep-time scale of geological processes, and that the proposed markers may not be globally synchronous. Proponents, in contrast, contend that the sheer scale and permanence of human alterations, including species extinction rates and landscape modifications, warrant a distinct designation. This debate underscores a broader tension between scientific classification and the societal implications of acknowledging humanity as a geological force.

B. B. Los geólogos prefieren centrarse en los cambios climáticos naturales en lugar de los impactos humanos.
C. C. El concepto carece de cualquier evidencia de influencia humana en los sistemas de la Tierra.
D. D. Las implicaciones sociales de la época son demasiado insignificantes para considerarse.
✅ 正确答案
A. The proposed markers are not universally accepted as being simultaneous across the globe.
