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. Proponents argue that markers such as plastic pollution, nuclear fallout, and elevated carbon dioxide levels are distinct enough to demarcate this era from the Holocene. However, critics contend that the term is more cultural than scientific, noting that geological time scales typically rely on natural, not anthropogenic, signals. They also point to the difficulty in establishing a precise global boundary stratum, as human effects vary widely across regions. Despite this debate, the term has catalyzed interdisciplinary research, prompting scholars to reconsider humanity's role as a planetary force and the long-term consequences of industrial activity.
❓ According to the passage, what is a primary reason some critics reject the 'Anthropocene' as a formal geological epoch?
A. The markers proposed are not sufficiently long-lasting.
B. It relies on human-induced signals rather than natural ones.
C. The industrial activity has not affected all regions equally.
D. The term has not gained support among environmental scientists.
✅ 正确答案
It relies on human-induced signals rather than natural ones.
