For almost 15 years, scientists have debated whether the Anthropocene should be an official geological epoch marking the profound influence of humans on the planet. Then in March, an international panel of scientists formally rejected the proposal for a new Anthropocene epoch.

In this episode, two scientists give us their different opinions on whether that was the right decision and what it means for the future use of the word Anthropocene. 

Featuring Jan Zalasiewicz, professor of palaeobiology at the University of Leicester in the UK, and Erle C. Ellis, professor of geography and environmental systems at the University of Maryland, Baltimore County in the US. Plus an introduction from Will de Freitas, environment and energy editor at The Conversation in the UK.

Gemma Ware is the executive producer. Full credits available here. A transcript will be available shortly. Subscribe to a free daily newsletter from The Conversation.
