Kumi Naidoo has spent his life fighting for human rights and climate justice.

In 1987 had to flee his native South Africa as a 22 year old because he was wanted by police for his role in fighting the racist Apartheid regime.

He went on the head both Greenpeace International and Amnesty International.

Kumi Naidoo tells Chris Cummins why we should listen to the Fridays For Future activists, particularly those from the global south. And why his experience with Apartheid showed him that peaceful civil disobedience might be the only way to ensure change but violence never is.
