The concept of the 'Anthropocene' has gained traction among geologists and environmental scientists as a proposed new geological epoch defined by human impact on Earth's systems. While the Holocene, which began approximately 11,700 years ago, has been characterized by relatively stable climatic conditions that facilitated the development of agriculture and complex societies, proponents of the Anthropocene argue that the mid-20th century marked a profound shift. This period, often termed the 'Great Acceleration', witnessed exponential growth in population, industrialization, and resource consumption, leaving detectable markers such as radioactive isotopes from nuclear tests, plastic pollution, and elevated carbon dioxide levels. However, critics question whether such changes constitute a distinct geological boundary, noting that human influences have been incremental rather than abrupt, and that formalizing the Anthropocene may oversimplify the complex, diachronous nature of environmental transformation.
❓ Согласно тексту, какой ключевой аргумент ПРОТИВ формализации антропоцена как новой геологической эпохи?
A. Воздействие человека было слишком постепенным и разнообразным, чтобы обозначить чёткую геологическую границу.
B. Голоценовая эпоха уже в достаточной мере отражает последствия человеческой деятельности.
C. Радиоактивные изотопы и пластиковое загрязнение не обнаруживаются в геологических слоях.
D. «Великое ускорение» на самом деле не привело к значительному росту населения.
✅ 正确答案
Human impacts have been too gradual and varied to mark a clear geological boundary.
