I'm highly political. I spend an awful lot of time in the U.S. trying to influence decision-makers. But I don't feel in tune with British politics.
I wasn't trying to be a scientist. I only ever wanted to be a naturalist, like a David Attenborough.
In 1975, when my students were kidnapped by rebels, I was accused of hiding instead of trying to save them, and of not giving enough money for their ransom. I wasn't believed.
So this is my effort to bring back the hope that we must have if we are to change direction. . . . I think to be fully human, we need to have meaning in our lives, and that's what I am trying to help these young people to find.
