The nature of AI: solving the planet's data gap | Drew Purves

Could we use the sound of a coral reef to determine its health? Do we know where all the world's natural forests are? And are we on the verge of using AI to decode animal communication? In this episode, Professor Hannah Fry is joined by Drew Purves, Nature Lead at Google DeepMind. They explore how AI is helping ecologists map forests and species for the first time in history and how this data can be used to better understand the root causes of deforestation.

They also explore bioacoustics and how sound is playing a pivotal role in tracking species on land and underwater —providing a powerful new way for us to understand and protect the environment.
