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.
❓ Согласно тексту, какова основная причина споров вокруг официального признания антропоцена новой геологической эпохой?
A. A. Предложенные маркеры антропоцена недостаточно постоянны или глобально согласованы.
B. B. Большинство геологов считают, что воздействие человека слишком незначительно, чтобы повлиять на геологические образования.
C. C. Термин «антропоцен» был придуман не учёными и не имеет научного обоснования.
D. D. Изменения, вызванные человеком, слишком медленны, чтобы их можно было наблюдать в геологической летописи.
✅ 正确答案
A. The proposed markers of the Anthropocene are not permanent or globally consistent enough.
