The Coronavirus pandemic can be seen as a huge ecological warning: a sign that our footprint on planet Earth is becoming terribly unsustainable. And while that crisis continues to - rightly - dominate global headlines it is still rarely seen as the environmental crisis that it is.

To answer this question and more hosts Zoe Williams and Luke Cooper are joined by Green Party co-leader, Sian Berry, to appraise the current state of the global climate emergency and what we need to do next.
