How do we know when a species is extinct? - Dr Barney Long - IFLScience The Big Questions
It’s no secret that species extinction and biodiversity loss are making our environment increasingly less stable. As it feels like we inch closer to waving goodbye to threatened animals like the Javan rhino, a question springs to mind: How do we know when a species is extinct? How, for instance, do we know there aren’t some animals left just hiding in a bush somewhere?
In this episode, host Rachael Funnell puts the question to Barney Long of Re:wild, who works on the conservation of endangered mammal species and ways of recovering their populations.
