The concept of the 'Anthropocene' has gained traction among geologists and environmental scientists 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 collisions, the Anthropocene is characterized by markers like 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 profound, is not yet comparable to the long-term, planet-scale changes that define earlier geological boundaries. Others counter that the rapid acceleration of anthropogenic effects since the mid-20th century, termed the 'Great Acceleration,' justifies a distinct classification. This debate highlights the tension between geological precision and the need to acknowledge humanity's unprecedented role in shaping the planet's future.
❓ According to the passage, what is the primary reason for the controversy surrounding the formal recognition of the Anthropocene as a geological epoch?
A. A. The markers of human impact, such as plastic and nuclear isotopes, are not globally distributed.
B. B. Some experts question whether human-induced changes are significant enough to match natural geological forces.
C. C. The 'Great Acceleration' has only been observed in the last few decades, which is too short for geological classification.
D. D. There is disagreement over whether the Anthropocene should be defined by carbon dioxide levels or radioactive isotopes.
✅ 正确答案
B. Some experts question whether human-induced changes are significant enough to match natural geological forces.
