The concept of the 'Anthropocene' has gained traction among geologists as a proposed new geological epoch characterized by significant human impact on Earth's geology and ecosystems. Proponents argue that markers such as nuclear fallout, plastic pollution, and elevated carbon dioxide levels are stratigraphically distinct, warranting formal recognition. Critics, however, contend that the term lacks precise temporal boundaries and that human influences are not uniformly synchronous across the globe. They suggest that the Holocene, the current interglacial period, already encompasses human activity, making a new epoch redundant. Despite this debate, the Anthropocene serves as a powerful heuristic for interdisciplinary research, prompting discussions on sustainability and planetary stewardship. Its formal adoption remains pending, yet its conceptual utility extends beyond geology into policy and public discourse.
❓ What is the main reason critics oppose the formal recognition of the Anthropocene as a new geological epoch?
A. A. The markers of human impact are not visible in the stratigraphic record.
B. B. Human activities have not significantly altered Earth's systems.
C. C. The proposed epoch lacks clear temporal boundaries and global consistency.
D. D. The Holocene is too short to include human activity.
✅ 正确答案
C. The proposed epoch lacks clear temporal boundaries and global consistency.
