Don't accept that you can't make a difference. Because if you can't make a difference, you won't make a difference, and if you put a multiplier on that we will continue on an unsustainable pathway.

I am convinced the prophets of doom have to be taken seriously.

My belief is that the purpose of economic life is to meet the social needs of people.

It is the responsibility of each human being today to choose between the force of darkness and the force of light. We must therefore transform our attitudes, and adopt a renewed respect for the superior laws of Divine Nature.

I am President of the UN created University for Peace, which has a strong commitment to the relationship between peace, security and the environment. I meet with young people around the world and I always come away enthused and encouraged.

I've got used to criticisms and, naturally, I try to make sure I don't listen to the more extreme ones because most of the people who have taken their rightwing extremist view of my life are people that I've never met.
