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. Unlike previous epochs, which were demarcated by natural events such as ice ages or asteroid impacts, the Anthropocene is characterized by markers like radioactive isotopes from nuclear tests, plastic pollution, and elevated carbon dioxide levels. However, scholars debate its formal recognition, arguing that human influence began thousands of years ago with agriculture, not just in the mid-20th century. This disagreement highlights the challenge of defining a time boundary when human activities have been gradual yet globally pervasive.
