Calling on governments to "tell the truth about the climate emergency", the Music Declares Emergency initiative has brought together artists including Billie Eilish, Massive Attack and Radiohead. Since its launch in France, it has attracted similar support. DJ and producer Fakear joins us to tell us why he signed up to the project, as well as how touring and festivals can become greener. As people around the world mark Earth Day, we talk about government responses to activism and the planet's capacity to regenerate with – or without – the human race.
