Ideas to change the world: Margaret Atwood talks to seven visionaries fighting for a brighter future

The author's hand-picked panel share their ideas on music, mushrooms, zombies and more

What do you get when you bring together some of the most revered thinkers, most progressive-minded activists and one of the most celebrated novelists writing today to discuss the immense challenges we face? A debate about the Spice Girls, of course! For the Guardian's Saturday magazine, Margaret Atwood wanted to gather some of her favourite experts from around the globe, to ask how they see the world we live in - and what they believe is key to creating the future they want to see.

The lineup included bestselling author Raj Patel, dubbed the rock star of social justice writing"; Senator Yvonne Boyer, the first Indigenous person appointed to the Canadian senate from Ontario; Akala, a writer, musician and poet; the excellently named Merlin Sheldrake, an expert on fungi; Kate Fletcher, whose speciality is sustainable fashion; Jessie Housty, a young Indigenous activist with a focus on decolonisation and community; and Yasmeen Hassan of Equality Now, which works to combat gender discrimination. The panel, hand-picked by Atwood, reflects the many disparate subjects the author is passionate about, and she was as keen to hear from them as they were to understand her vision and ideas.
