I had a series of mini-breakdowns where the public persona - this thing, this face, this person who writes this music... I would walk past that person in the mirror or listen to that person playing guitar and I didn't know who they were.

And I know I'm paranoid and neurotic, I've made a career out of it.

Someone needs to tell the truth, but it shouldn't be my job.

Music is more difficult - try naming a political band. The Dead Kennedys. The Dead Kennedys are political, but they are more funny than they are political.

My main argument is that environmental destruction comes when people externalise their costs and pass them on to future generations. That is obviously something that large enterprises do and they become large by doing it.

Even the government understands that the environmental challenge is so big that no single agency can handle it. It needs collaboration among all the stakeholders - companies, governments, NGOs and the public. Public accountability will be the ultimate driving force.

I believe we should reframe our response to climate change as an imperative for growth rather than merely being a way of being green or meeting environmental commitments.

I think we're taking a snapshot view of climate change and trying to implement policy based on that snapshot.
