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 from atomic tests, and elevated carbon dioxide levels provide clear stratigraphic evidence of a distinct boundary. However, critics contend that the term is more political than scientific, suggesting that human activity has been altering the environment for millennia, without a single, globally synchronous start date. Despite this debate, the term has proven useful in fostering interdisciplinary dialogue about sustainability and planetary stewardship.
