The concept of the 'Anthropocene' has gained traction among geologists and environmental scientists as a proposed new geological epoch characterized by significant human impact on Earth's geology and ecosystems. Unlike previous epochs, which were defined by natural climatic shifts or biological events, the Anthropocene is marked by anthropogenic markers such as radioactive isotopes from nuclear tests, plastic pollution, and elevated carbon dioxide levels. Proponents argue that these markers are distinct and persistent enough to warrant a formal boundary in the geological time scale. However, critics contend that the term overstates humanity's influence relative to natural processes, which have historically driven planetary change over millions of years. They also question whether the human footprint is globally synchronous, as geological epochs require a clear, worldwide starting point. This debate highlights the tension between scientific classification and the broader narrative of human agency in shaping the planet.
❓ Согласно тексту, какая из следующих причин является ключевой для того, почему некоторые учёные выступают против официального определения антропоцена как геологической эпохи?
A. Маркеры человеческой деятельности недостаточно отличимы от природных процессов.
B. Влияние человека на планету слишком недавнее, чтобы его можно было точно измерить.
C. Предложенные маркеры могут не появляться одновременно по всему миру.
D. Термин «антропоцен» слишком политизирован для научного использования.
✅ 正确答案
The proposed markers may not appear simultaneously across the globe.
