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.
❓ Какова основная причина споров вокруг официального признания антропоцена новой геологической эпохой?
A. A. Учёные не могут прийти к единому мнению о точной дате начала антропоцена.
B. B. Некоторые утверждают, что изменения, вызванные человеком, недостаточно стратиграфически различимы, в то время как другие считают, что они уже превышают воздействия уровня голоцена.
C. C. Термин «антропоцен» не получил широкого признания среди общественности.
D. D. Нет доказательств воздействия человека на глобальные системы.
✅ 正确答案
B. Some argue human changes are not stratigraphically distinct enough, while others believe they already exceed Holocene-level impacts.
