One of the things that I noticed with my own eyes was Nelson Mandela ability to engage with kings and queens and heads of state on the one hand, and his ability to engage with ordinary people, equally comfortably.

Currently, we allow our political and business leaders to get away with murder. Now is the time to change that. We need direct liability for those who are destroying our future and this planet. We need fast, profound and systemic change. History only moves forward when courageous people get up and act. That's why I support this citizens' initiative to recognise ecocide as the crime it is.

I think even though he [Nelson Mandela] was feted and praised as he was, he always was at pains to say, I'm a human being.

Nelson Mandela also spoke about how, as a human being, he's made mistakes.

Investing one cent more in oil, coal and gas is investing in the death of society, and the in the death of our children.

In Durban, where I was born and grew up, and all over Africa, Nelson Mandela was a hero! Now he is a hero to the world.

I was 15 years old when I first heard the name Mandela, or Madiba, as he is fondly known in Africa. In apartheid South Africa he was public enemy number one. Shrouded in secrecy, myth and rumour, the media called him 'The Black Pimpernel'.
