Benedict Cumberbatch has released a new documentary, How to Live on Earth, which launches on YouTube this month and features him delivering monologues from London's Natural History Museum interspersed with short films about activists, scientists and chefs pioneering more sustainable ways of living. The actor, a long-time environmental campaigner, hopes the film will serve as a "blueprint" for humanity's future relationship with the planet, framing the current period of extreme climate impacts as a decisive moment to act.

In the interview, Cumberbatch discusses how his vegan diet clashed with filming demands on The Courier, where he was told to eat lean meat for health reasons, and explains he now eats ethically sourced venison due to the UK's deer overpopulation. He also details his work with the Green Rider movement, which pushes for emissions-cutting measures to become contractual requirements on film sets, including talks with Disney over its UK Avengers production, while defending the right to peaceful climate protest amid government crackdowns on activists.
