How do you measure biodiversity? From the forests of Borneo, with the help of a pioneering team of scientists, Fidelity have followed a project to explore if sound recordings - layered with artificial intelligence - could help to solve biodiversity's data issue. Analyst Minlin Lee travelled to Indonesia to see, and hear, the data gathering in action, while Charlotte Apps followed the analysis in the south of France.

Back in the studio, Richard Edgar is joined by Fidelity International's Global Head of Stewardship and Sustainable Investing, Jenn-Hui Tan, to discuss why investors should be aware of nature loss. 

With additional contributions from Portfolio Manager Velislava Dimitrova and Director of the Natural History Museum in London, Dr Doug Gurr.
