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 and biological evolution, 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 activity has been altering the environment for millennia, making it difficult to pinpoint a precise starting point. Proponents suggest the mid-20th century, coinciding with the 'Great Acceleration' of industrial growth and global-scale impacts, as the most appropriate boundary. This debate highlights broader questions about how humanity's legacy will be preserved in the geological record and whether our species' influence warrants a distinct stratigraphic designation.
❓ Согласно тексту, почему формальное признание антропоцена вызывает споры?
A. A) Поскольку воздействие человека на окружающую среду было относительно незначительным по сравнению с природными изменениями.
B. B) Потому что существуют разногласия относительно того, когда влияние человека начало определять отдельную геологическую эпоху.
C. C) Потому что радиоактивные осадки и загрязнение пластиком не считаются долговечными геологическими маркерами.
D. D) Потому что концепция антропоцена не находит поддержки в научном сообществе.
✅ 正确答案
B) Because there is disagreement over when human influence began to define a distinct geological epoch.
