Tom Mustill is a biologist turned filmmaker and writer who tells stories about the relationship between people and nature. His television documentaries over two decades for the BBC, National Geographic and PBS have been played in Times Square and the UN General Assembly in New York and projected onto the cliffs of Dover and the Pyramid Stage at Glastonbury. His award-winning short film #Naturenow (2019) highlights natural solutions to climate change – translated into 64 languages, it has been viewed over 80 million times. In 2015, Mustill was almost killed when a humpback whale leapt onto his kayak, inspiring a book and various whale-related projects.

Mustill co-hosts a podcast about the nature and climate crisis with journalist Lucy Siegle, who is captured with him in this photograph.

Journalist and writer Lucy Siegle has been involved in contemporary environmentalism for two decades, mainstreaming action on the climate and nature crisis on TV and through her writing. Her book To Die For: Is Fashion Wearing out the World? (2011) spawned the hit documentary The True Cost. Siegle was the first to write an environmental column in a national UK newspaper (the Observer, for 14 years) and has interviewed everyone from Sir David Attenborough to Björk on the future of the planet. She co-founded the Green Carpet Challenge and is a trustee of Surfers Against Sewage and ambassador for WWF UK.
