How to be a powerful youth campaigner?

Christina Adane is co-chair of Bite Back 2030, a youth-led movement to fix the food system, and is one of the BBC's top 100 women of 2020. She launched a petition last year on free school meals that got 500,000 signatures and inspired Marcus Rashford's campaign. She speaks to our CEO Olly Buston about how people her age or younger can make change happen.
