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 shaped by natural forces such as volcanic activity 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 scholars argue that human influence, while pervasive, does not yet represent a distinct stratigraphic boundary comparable to those of the Pleistocene-Holocene transition. Others contend that the scale and irreversibility of changes, such as biodiversity loss and climate alteration, justify a new epoch. This debate underscores a broader challenge in stratigraphy: balancing geological precision with the need to communicate planetary-scale changes.
❓ Какова основная причина споров вокруг официального признания антропоцена в качестве геологической эпохи?
A. A. Воздействие человека пока не обнаруживается в геологических записях.
B. B. Некоторые учёные ставят под сомнение, соответствуют ли изменения, вызванные деятельностью человека, критериям для выделения отдельной стратиграфической границы.
C. C. Эпоха не имеет чётких маркеров, таких как радиоактивные изотопы или загрязнение пластиком.
D. D. Геологи согласны, что природные силы по-прежнему являются основными движущими факторами геологических изменений.
✅ 正确答案
B. Some scholars question whether human-induced changes meet the criteria for a distinct stratigraphic boundary.
IELTS Reading Tips
Skim the questions first, underline keywords, then locate in the passage
Watch for paraphrasing; correct answers are often reworded
Be wary of absolute statements (all, always, never) — usually wrong
Pay attention to content after transition words (however, but, yet)
