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. Proponents argue that markers such as plastic pollution, nuclear fallout from atomic tests, and elevated carbon dioxide levels provide clear stratigraphic evidence. However, critics contend that the term lacks precise temporal boundaries, as human influence began at different times across regions. Moreover, some scholars suggest that framing the current era as a distinct epoch oversimplifies the complex interplay between natural and anthropogenic processes. Despite this debate, the term has proven valuable in raising public awareness about humanity's role in shaping the planet's future, prompting interdisciplinary research that bridges geology, ecology, and social sciences.
