When I was younger, I read a book by Frank Barnaby, this wonderful nuclear physicist. He said that media had a responsibility, that all sectors of society had a responsibility to try and move things forward. And that fascinated me... I'd been messing around with a camera most of my life...

I always thought I was really thick.

We're in this together, and if we united and we inter-culturally cooperated, then that might be the key to humanity's survival.

We all want a world without war, without conflict, without human suffering.

I think there's a number of pillars to success. One is you've got to have a great idea. The other is you've got to have a constituency, you've got to have finance, and you've got to be able to raise awareness.

We need to support the governments of the world to create the world we want and I also think we need to empower the UN so that the secretariat, the people who work day in and day out, know that the people are behind them.

World Peace Day is envisioned to become a moment of global unity - it is up to each and every one of us to make this a reality.
