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 radioactive isotopes from nuclear tests, plastic pollution, and elevated carbon dioxide levels provide clear stratigraphic evidence. However, critics contend that the epoch's onset is difficult to pinpoint, with some suggesting the Industrial Revolution as a start date, while others advocate for the mid-20th century 'Great Acceleration'. This debate highlights the challenge of integrating human history with deep geological timescales, raising questions about how we define and periodize our own impact on the planet.
