📖 Reading Passage

The concept of the 'Anthropocene' has gained traction among geologists as a proposed new geological epoch defined by human impact on Earth's systems. 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. Some scholars argue that human-induced changes are not yet stratigraphically distinct enough to warrant a separate epoch, while others contend that the scale and permanence of these changes, including species extinction rates and altered nitrogen cycles, already surpass those of the Holocene. This debate reflects a broader tension between scientific classification and societal awareness, as naming a new epoch carries profound implications for how humanity perceives its role in planetary history.
❓ ¿Cuál es la razón principal de la controversia sobre el reconocimiento formal del Antropoceno como una nueva época geológica?

✅ 正确答案

B. Some argue human changes are not stratigraphically distinct enough, while others believe they already exceed Holocene-level impacts.
