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 characterized by natural climatic shifts or biological events, the Anthropocene is marked by human-induced changes such as nuclear fallout, plastic pollution, and accelerated species extinction. However, the formal recognition of this epoch remains contentious. Critics argue that human impacts are not synchronous globally, with different regions experiencing changes at different times, making a single global boundary difficult to establish. Proponents counter that markers like the radioactive isotopes from mid-20th-century nuclear tests provide a clear, worldwide signal. This debate highlights a deeper issue: whether geological classification should prioritize measurable physical evidence or acknowledge the unprecedented scale of human agency in shaping planetary processes.
❓ Согласно тексту, какова основная причина, по которой некоторые ученые выступают против официального признания антропоцена в качестве геологической эпохи?
A. A) Воздействие человека на окружающую среду распределено по земному шару неравномерно, что затрудняет определение единой даты начала.
B. B) Маркеры, используемые для определения эпохи, такие как радиоактивные осадки, не обнаруживаются во всех регионах.
C. C) Концепция слишком большое внимание уделяет человеческой деятельности и игнорирует природные процессы.
D. D) Предложенная эпоха не имеет достаточных физических доказательств для подтверждения её существования.
✅ 正确答案
A) Human impacts are not evenly distributed across the globe, complicating the identification of a single start date.
