The concept of the 'Anthropocene' has gained traction among geologists as a proposed new geological epoch defined by significant human impact on Earth's geology and ecosystems. Unlike previous epochs, which were marked by natural events such as ice ages or asteroid impacts, the Anthropocene is characterized by anthropogenic markers, including radioactive isotopes from nuclear tests, plastic pollution, and elevated carbon dioxide levels. However, the formal recognition of this epoch remains contentious. Some scientists argue that the changes are so profound and rapid that they warrant a distinct stratigraphic boundary, while others contend that human influence, though substantial, has not yet produced a globally synchronous and permanent signal in the rock record. This debate highlights the challenge of integrating human history with deep geological time, forcing a reconsideration of how we define and divide the planet's history.
❓ Según el pasaje, ¿cuál es la razón principal de la controversia sobre el reconocimiento formal del Antropoceno como una nueva época geológica?
A. A. Los marcadores propuestos del Antropoceno no son lo suficientemente permanentes ni consistentes a nivel global.
B. B. La mayoría de los geólogos creen que el impacto humano es demasiado trivial para afectar las formaciones geológicas.
C. C. El término 'Antropoceno' fue inventado por no científicos y carece de base científica.
D. D. Los cambios causados por los humanos son demasiado lentos para ser observados en el registro de rocas.
✅ 正确答案
A. The proposed markers of the Anthropocene are not permanent or globally consistent enough.
