Veganuary ambassadors Joaquin Phoenix, Kellie Bright, George Monbiot, Alicia Silverstone, Evanna Lynch, Peter Egan, Jasmine Harman, Melody Kane, Sara Pascoe, and Chris Packham have joined forces with the vegan charity, launching its 2020 campaign to encourage fans to adopt a plant-based diet in the New Year and 'fight climate chaos'.

Joker star Phoenix commented 'If you look at the climate crisis or the violence of our food system and feel helpless, thinking "I wish there was something I could do" - you can. Right now. Sign up to try vegan this January'.
